WildFly 32

Configure the application server according to instructions in the following sections.

 

Download WildFly

WildFly can either be downloaded as a zip package or customized using Galleon. We recommend you to use Galleon, since it only downloads the components you need, as opposed to using the zip package, which bundles all configurations and JBoss modules (EJBCA is only using a subset of all functionality in WildFly).

WildFly is usually put in the /opt folder on Linux systems, and using a symlink to the WildFly folder makes it easy to switch to a new version of WildFly by simply overriding the symlink.

Using the Zip Package

You need to use the Jakarta EE Full & Web Distribution package of WildFly when downloading the zip package. If you have not downloaded WildFly already, you can use the following command to do so:

Download and unpack the WildFly zip package

BASH 
wget https://github.com/wildfly/wildfly/releases/download/32.0.0.Final/wildfly-32.0.0.Final.zip -O /tmp/wildfly-32.0.0.Final.zip
unzip -q /tmp/wildfly-32.0.0.Final.zip -d /opt/
ln -snf /opt/wildfly-32.0.0.Final /opt/wildfly

Using Galleon

Instead of downloading the WildFly zip package containing everything (all default server configurations and all JBoss modules), using Galleon tooling you can choose to only install the components needed by EJBCA.

Download Galleon

Galleon is provided as a zip package from GitHub which you can download and run without any installation.

Download Galleon

BASH 
wget https://github.com/wildfly/galleon/releases/download/6.0.0.Final/galleon-6.0.0.Final.zip -O /tmp/galleon-6.0.0.Final.zip
unzip -q /tmp/galleon-6.0.0.Final.zip -d /tmp/
cd /tmp/galleon-6.0.0.Final/bin

Layers Used By EJBCA

The table below lists the Galleon layers used by EJBCA.

The core-tools layer will include the JBoss and Elytron CLI which comes in handy if the Elytron credential store or the standalone.xml configuration file need to be tweaked later. If you don't need this, exclude the core-tools and management layers and add elytron separately. bean-validation can be excluded as well, but is good to have, at least in staging environments. Picketbox-based web security is deprecated and replaced with the cloud-server layer which is required for EJBCA to detect authentication using client certificates.

Download and Configure WildFly Using Galleon

Galleon can download and extract WildFly to the directory specified using the install command. EJBCA is running on a standalone server, and only this server configuration is needed. For a typical installation, use the following CLI recipe:

Download and build WildFly using Galleon

BASH 
./galleon.sh install wildfly:current#32.0.0.Final --dir=/opt/wildfly-32.0.0.Final --default-configs=standalone/standalone.xml --layers=cloud-server,deployment-scanner,ejb-lite,remoting,resource-adapters,undertow,io,jsf,mail,webservices,-jsonb,-jms-activemq,-observability,-jmx-remoting,-messaging-activemq
ln -snf /opt/wildfly-32.0.0.Final /opt/wildfly

When building EJBCA from source you need to have bin/client/jboss-client.jar in your WildFly directory at compile time for the CLI tools to work. This jar file is not available when building WildFly using Galleon, but you can fetch it manually from the Maven Central Repository.

CODE 
mkdir /opt/wildfly/bin/client
wget https://repo1.maven.org/maven2/org/wildfly/wildfly-client-all/32.0.0.Final/wildfly-client-all-32.0.0.Final.jar -O /opt/wildfly/bin/client/jboss-client.jar

Remove RESTEasy-Crypto

The application server can sometimes load its own version of Bouncy Castle, resulting in incompatibility and/or conflict issues.

The following displays an example log message in case of a conflict:

ERROR [StartupSingletonBean] BouncyCastle is not loaded by an EJBCA classloader, version conflict is likely

A typical error occurring as a consequence of the wrong Bouncy Castle being loaded in EJBCA is:

ClassCastException setting BagAttributes, can not set friendly name: : java.lang.ClassCastException: org.bouncycastle.jcajce.provider.asymmetric.x509.X509CertificateObject cannot be cast to org.bouncycastle.jce.interfaces.PKCS12BagAttributeCarrier

To avoid issues and prevent WildFly from loading the Bouncy Castle library included in the RESTEasy-Crypto module, rather than the library included in EJBCA, run the following:

CODE 
sed -i '/.*org.jboss.resteasy.resteasy-crypto.*/d' /opt/wildfly/modules/system/layers/base/org/jboss/as/jaxrs/main/module.xml
rm -rf /opt/wildfly/modules/system/layers/base/org/jboss/resteasy/resteasy-crypto/

Create a Custom Configuration

Replace /opt/wildfly/bin/standalone.conf with the following Jinja2 template.

/opt/wildfly/bin/standalone.conf

BASH 
if [ "x$JBOSS_MODULES_SYSTEM_PKGS" = "x" ]; then
     JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman"
fi

if [ "x$JAVA_OPTS" = "x" ]; then
     JAVA_OPTS="-Xms{{ HEAP_SIZE }}m -Xmx{{ HEAP_SIZE }}m"
     JAVA_OPTS="$JAVA_OPTS -Dhttps.protocols=TLSv1.2,TLSv1.3"
     JAVA_OPTS="$JAVA_OPTS -Djdk.tls.client.protocols=TLSv1.2,TLSv1.3"
     JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true"
     JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS"
     JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true"
     JAVA_OPTS="$JAVA_OPTS -Djboss.tx.node.id={{ TX_NODE_ID }}"
     JAVA_OPTS="$JAVA_OPTS -XX:+HeapDumpOnOutOfMemoryError"
     JAVA_OPTS="$JAVA_OPTS -Djdk.tls.ephemeralDHKeySize=2048"
else
     echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
fi

When installing EJBCA Community Edition, add an additional JAVA_OPTS parameter to enable the use of PKCS#11 tokens with Java 17 and later:

BASH 
echo -e "\nJAVA_OPTS=\"\$JAVA_OPTS --add-exports=jdk.crypto.cryptoki/sun.security.pkcs11.wrapper=ALL-UNNAMED\"" >> /opt/wildfly/bin/standalone.conf

Set Allowed Memory Usage

By default, 512 MB of heap (RAM) is allowed to be used by the application server. This is not sufficient to run EJBCA. We recommend to allocate at least 2048 MB of RAM. To increase the default value, run the following command:

BASH 
sed -i -e 's/{{ HEAP_SIZE }}/2048/g' /opt/wildfly/bin/standalone.conf

Set the Transaction Node ID

Set the transaction node ID to a unique number. The node ID is used by the transactions subsystem and ensures that the transaction manager only recovers branches which match the specified identifier. It is imperative that this identifier is unique between WildFly instances sharing either an object store or access common resource managers (i.e. when EJBCA is operating in a cluster).

BASH 
sed -i -e "s/{{ TX_NODE_ID }}/$(od -A n -t d -N 1 /dev/urandom | tr -d ' ')/g" /opt/wildfly/bin/standalone.conf

Configure WildFly as a Service

Modern Linux systems use systemd to start and stop services. The WildFly zip package already contains the necessary files to run as a service, but they need to be installed manually. Once started as a service, WildFly will run as the wildfly user, and we need to add this user as well.

BASH 
cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin
cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system
mkdir /etc/wildfly
cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly
systemctl daemon-reload
useradd -r -s /bin/false wildfly
chown -R wildfly:wildfly /opt/wildfly-32.0.0.Final/

The docs directory does not exist when using Galleon. For reference, this is what the missing files look like:

/opt/wildfly/docs/contrib/scripts/systemd/launch.sh

BASH 
#!/bin/bash
if [ "x$WILDFLY_HOME" = "x" ]; then
    WILDFLY_HOME="/opt/wildfly"
fi
if [[ "$1" == "domain" ]]; then
    $WILDFLY_HOME/bin/domain.sh -c $2 -b $3
else
    $WILDFLY_HOME/bin/standalone.sh -c $2 -b $3
fi

launch.sh

Based on your O/S, you might need to make launch.sh file executable.

/opt/wildfly/docs/contrib/scripts/systemd/wildfly.service

Start WildFly

Start WildFly as a service.

BASH 
systemctl start wildfly

Or if you prefer running it just on the console (no service).

CODE 
/opt/wildfly/bin/standalone.sh

Create an Elytron Credential Store

You can protect passwords by storing them in a credential store. The credential is encrypted with a master password which is fetched by WildFly on startup.

Create a Master Password

Create a script which outputs the master password to stdout and ensure the script can only be executed by the wildfly user.

BASH 
echo '#!/bin/sh' > /usr/bin/wildfly_pass
echo "echo '$(openssl rand -base64 24)'" >> /usr/bin/wildfly_pass
chown wildfly:wildfly /usr/bin/wildfly_pass
chmod 700 /usr/bin/wildfly_pass

Create the Credential Store

Create a credential store in /opt/wildfly/standalone/configuration encrypted with the password echoed by the wildfly_pass script.

BASH 
mkdir /opt/wildfly/standalone/configuration/keystore
chown wildfly:wildfly /opt/wildfly/standalone/configuration/keystore
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add(path=keystore/credentials, relative-to=jboss.server.config.dir, credential-reference={clear-text="{EXT}/usr/bin/wildfly_pass", type="COMMAND"}, create=true)'

Add Database Driver

For most database management systems, the JDBC driver can be added by hot-deploying it into the deployment directory. This will be picked up by WildFly and deployed so we can create a data source straight away. You can use a generic name, without version number, in order to get a generic driver-name for the data source command.

MariaDB

Download and deploy MariaDB JDBC driver

BASH 
wget https://dlm.mariadb.com/3852266/Connectors/java/connector-java-3.4.1/mariadb-java-client-3.4.1.jar -O /opt/wildfly/standalone/deployments/mariadb-java-client.jar

PostgreSQL

Download and deploy PostgreSQL JDBC driver

BASH 
wget https://jdbc.postgresql.org/download/postgresql-42.2.18.jar -O /opt/wildfly/standalone/deployments/postgresql-jdbc4.jar

Microsoft SQL Server

Download and deploy Microsoft SQL Server JDBC driver

BASH 
wget https://github.com/microsoft/mssql-jdbc/releases/download/v12.8.1/mssql-jdbc-12.8.1.jre11.jar -O /opt/wildfly/standalone/deployments/mssql-jdbc.jre11.jar

Other Databases

If you are using another type of database, copy the JDBC driver to the deployment directory and make note of the driver class and driver-name shown in the server log, for later use when adding the data source. For example:

TEXT 
... INFO  [org.jboss.as.connector.deployers.jdbc] (...) WFLYJCA0005: Deploying non-JDBC-compliant driver class org.driver.class (version X.Y.Z)
... INFO  [org.jboss.as.connector.deployers.jdbc] (...) WFLYJCA0022: Started Driver service with driver-name = jdbc-driver.jar

Add a Datasource

To add a datasource for EJBCA to use, run the commands in JBoss CLI according to the examples below.

Note that --driver-name is should be the same as the filename of the JAR file you copied in the step above.

The --jndi-name is is defined by the property datasource.jndi-name in database.properties, and the default value is used in the following example.

The --user-name and --password defines the username and password of the EJBCA database user. They correspond to the username and password defined by the properties database.username and database.password in database.properties. In production this password should be changed to a "real" password.

MariaDB

For MariaDB, run the following:

XML 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=dbPassword, secret-value="ejbca")'
/opt/wildfly/bin/jboss-cli.sh --connect 'data-source add --name=ejbcads --connection-url="jdbc:mysql://127.0.0.1:3306/ejbca?permitMysqlScheme" --jndi-name="java:/EjbcaDS" --use-ccm=true --driver-name="mariadb-java-client.jar" --driver-class="org.mariadb.jdbc.Driver" --user-name="ejbca" --credential-reference={store=defaultCS, alias=dbPassword} --validate-on-match=true --background-validation=false --prepared-statements-cache-size=50 --share-prepared-statements=true --min-pool-size=5 --max-pool-size=150 --pool-prefill=true --transaction-isolation=TRANSACTION_READ_COMMITTED --check-valid-connection-sql="select 1;"'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

MariaDB Connection URL

If you are using MariaDB connector of versions >= 3.0:


(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

PostgreSQL

For PostgreSQL, run the following:

CODE

/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Microsoft SQL Server

For Microsoft SQL Server, run the following:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=dbPassword, secret-value="ejbca")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads:add(connection-url="jdbc:sqlserver://foobar.YOUR.DOMAIN:1433;DatabaseName=ejbca;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;sendStringParametersAsUnicode=false", min-pool-size=5, max-pool-size=150, jndi-name="java:/EjbcaDS", driver-name=mssql-jdbc.jre11.jar, user-name="ejbca", credential-reference={store=defaultCS, alias=dbPassword}, pool-prefill=false, pool-use-strict-min=false, idle-timeout-minutes=2)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Other Databases

If you are using another type of database, adapt the statement above with the correct --driver-name, --connection-url, --driver-class and --check-valid-connection-sql.

Configure WildFly Remoting

EJBCA needs to use JBoss Remoting for the EJBCA CLI to work. Configure it to use a separate port 4447 and remove any other dependency on remoting except for what EJBCA needs.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=remoting/http-connector=http-remoting-connector:write-attribute(name=connector-ref,value=remoting)'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=remoting:add(port=4447,interface=management)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/http-listener=remoting:add(socket-binding=remoting,enable-http2=true)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Configure Logging

Configure logging in WildFly to be able to dynamically change logging while the application server is running.

Logging Configurations

Choose one of the logging configurations below.

Option 1 - Recommended Logging

INFO log level for org.ejbca, org.cesecore and com.keyfactor is recommended for production systems.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca:add(level=INFO)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore:add(level=INFO)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=com.keyfactor:add(level=INFO)'

Option 2 - Quiet Logging

If you prefer more quiet logging, configure WildFly to only log audit log messages, warnings and errors.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.audit.impl.log4j.Log4jDevice:add(level=INFO)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=com.keyfactor:add(level=WARN)'

Additional Logging Configuration

You may additionally want to add the following configuration:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.jboss.as.config:write-attribute(name=level, value=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.jboss:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.wildfly:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.xnio:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.hibernate:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.apache.cxf:add(level=WARN)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.config.ConfigurationHolder:add(level=WARN)'

Add Access Logging

To log all requests processed by the server, similar to the Apache access log, add the following configuration:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/setting=access-log:add(pattern="%h %t \"%r\" %s \"%{i,User-Agent}\"", relative-to=jboss.server.log.dir, directory=access-logs)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=io.undertow.accesslog:add(level=INFO)'

Remove the Console Handler

Console logging is not used when running WildFly with systemd, and removing it can increase logging performance.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/root-logger=ROOT:remove-handler(name=CONSOLE)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/console-handler=CONSOLE:remove()'

Remove Old Log Files

Log files are rotated on a daily basis by default, but old log files are not deleted automatically. You can delete old log files using a cronjob:

/etc/cron.daily/remove-old-wildfly-logs.sh

BASH 
#!/bin/sh
# Remove log files older than 7 days
find /opt/wildfly/standalone/log/ -type f -mtime +7 -name 'server.log*' -execdir rm -- '{}' \;

Make the file executable:

CODE 
chmod +x /etc/cron.daily/remove-old-wildfly-logs.sh

Enable Syslog Shipping

To additionally send the server log over UDP to a syslog server such as Graylog or Logstash, configure a syslog handler in WildFly. Set the hostname and port of the syslog server, as well as the desired log level according to the following example:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/json-formatter=logstash:add(exception-output-type=formatted, key-overrides=[timestamp="@timestamp"],meta-data=[@version=1])'
/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=logging/syslog-handler=syslog-shipping:add(app-name=EJBCA,enabled=true,facility=local-use-0,hostname=$(hostname -f),level=INFO,named-formatter=logstash,port=514,server-address=syslog.server,syslog-format=RFC5424)"
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/root-logger=ROOT:add-handler(name=syslog-shipping)'

Enable Audit Logging To File

You can write the EJBCA audit log to a separate file. E.g. to log to /opt/wildfly/standalone/log/cesecore-audit.log, rotate every 128 MB and keep one rotated file:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/size-rotating-file-handler=cesecore-audit-log:add(file={path=cesecore-audit.log, relative-to=jboss.server.log.dir}, max-backup-index=1, rotate-size=128m)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.audit.impl.log4j.Log4jDevice:add'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.audit.impl.log4j.Log4jDevice:add-handler(name=cesecore-audit-log)'

Configure OCSP Logging

If you have enabled the OCSP audit log or the OCSP transaction log, configure an asynchronous logger in WildFly for best performance.

For the OCSP transaction log:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.certificates.ocsp.logging.TransactionLogger:add(use-parent-handlers=false)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.certificates.ocsp.logging.TransactionLogger:write-attribute(name=level, value=INFO)'

Archive rotated log files to save disk space using a cron job:

/etc/cron.daily/archive-rotated-ocsp-logs.sh

BASH 
#!/bin/sh
# Compress the OCSP audit log and the OCSP transaction log after rotation
xz /opt/wildfly/standalone/log/ocsp-tx.log.*
xz /opt/wildfly/standalone/log/ocsp-audit.log.*

Make the file executable:

CODE 
chmod +x /etc/cron.daily/archive-rotated-ocsp-logs.sh

HTTP(S) Configuration

The following section explains how to configure HTTP(S) using Undertow.

Remove Existing TLS and HTTP Configuration

Run the following commands in JBoss CLI to remove existing TLS and HTTP configuration:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/http-listener=default:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=http:remove()'
# Line 4 is not needed if Galleon was used
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=https:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=https:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Use 3-Port Separation

The following section explains how to set up Undertow with 3-port separation. Port 8080 is used for HTTP (unencrypted traffic), port 8442 for HTTPS (encrypted) traffic with only server authentication and port 8443 for HTTPS (encrypted) traffic with both server and client authentication.

You can also choose to set up with 2-port separation instead, if so see the next section instead.

Add New Interfaces and Sockets

To add new interfaces and sockets, use the following:

Consider binding to a specific interface instead of binding to all interfaces using 0.0.0.0.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/interface=http:add(inet-address="0.0.0.0")'
/opt/wildfly/bin/jboss-cli.sh --connect '/interface=httpspub:add(inet-address="0.0.0.0")'
/opt/wildfly/bin/jboss-cli.sh --connect '/interface=httpspriv:add(inet-address="0.0.0.0")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=http:add(port="8080",interface="http")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=httpspub:add(port="8442",interface="httpspub")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=httpspriv:add(port="8443",interface="httpspriv")'

Configure TLS

Configure TLS according to the following instructions.

Make sure the password of the keystore and truststore in this section are correct, in order for the deployment not to fail. In production the passwords should be changed to "real" passwords.

Note that the following configuration uses PKCS12 as type for keystore. If your keystore is in JKS format, please change accordingly.

Configure httpsserver.tokentype=P12 in the EJBCA configuration file web.properties.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=httpsKeystorePassword, secret-value="serverpwd")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=httpsTruststorePassword, secret-value="changeit")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKS:add(path="keystore/keystore.p12",relative-to=jboss.server.config.dir,credential-reference={store=defaultCS, alias=httpsKeystorePassword},type=PKCS12)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsTS:add(path="keystore/truststore.p12",relative-to=jboss.server.config.dir,credential-reference={store=defaultCS, alias=httpsTruststorePassword},type=PKCS12)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-manager=httpsKM:add(key-store=httpsKS,algorithm="SunX509",credential-reference={store=defaultCS, alias=httpsKeystorePassword})'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/trust-manager=httpsTM:add(key-store=httpsTS)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/server-ssl-context=httpspub:add(key-manager=httpsKM,protocols=["TLSv1.3","TLSv1.2"],use-cipher-suites-order=false,cipher-suite-filter="TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256",cipher-suite-names="TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/server-ssl-context=httpspriv:add(key-manager=httpsKM,protocols=["TLSv1.3","TLSv1.2"],use-cipher-suites-order=false,cipher-suite-filter="TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256",cipher-suite-names="TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256",trust-manager=httpsTM,need-client-auth=true)'

Add HTTP(S) Listeners

To add HTTP(S) listeners:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/http-listener=http:add(socket-binding="http", redirect-socket="httpspriv")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=httpspub:add(socket-binding="httpspub", ssl-context="httpspub", max-parameters=2048)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=httpspriv:add(socket-binding="httpspriv", ssl-context="httpspriv", max-parameters=2048)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Configure the Firewall

Open port 8080, 8442 and 8443 for incoming TCP traffic.

Open ports in RHEL / CentOS

CODE 
systemctl enable firewalld --now
firewall-cmd --set-default-zone=dmz
firewall-cmd --zone=dmz --permanent --add-port 8080/tcp
firewall-cmd --zone=dmz --permanent --add-port 8442/tcp
firewall-cmd --zone=dmz --permanent --add-port 8443/tcp
firewall-cmd --reload

Use 2-Port Separation

The following section explains how to set up Undertow with 2-port separation. Port 8080 is used for HTTP (unencrypted traffic) and port 8443 is used for HTTPS (encrypted) traffic with optional client authentication.

If you configured to use 3-port separation above, this section must be ignored.

Add New Interfaces and Sockets

To add new interfaces and sockets, use the following:

Consider binding to a specific IP instead of binding to all interfaces using 0.0.0.0.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/interface=http:add(inet-address="0.0.0.0")'
/opt/wildfly/bin/jboss-cli.sh --connect '/interface=https:add(inet-address="0.0.0.0")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=http:add(port="8080",interface="http")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=https:add(port="8443",interface="https")'

Configure TLS

Configure TLS according to the following instructions.

Make sure the password of the keystore and truststore in this section are correct, in order for the commands not to fail. In production the passwords should be changed to "real" passwords.

Note that the following configuration uses PKCS12 as type for keystore. If your keystore is in JKS format, please change accordingly.

Configure httpsserver.tokentype=P12 in the EJBCA configuration file web.properties.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=httpsKeystorePassword, secret-value="serverpwd")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=httpsTruststorePassword, secret-value="changeit")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKS:add(path="keystore/keystore.p12",relative-to=jboss.server.config.dir,credential-reference={store=defaultCS, alias=httpsKeystorePassword},type=PKCS12)'

/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-manager=httpsKM:add(key-store=httpsKS,algorithm="SunX509",credential-reference={store=defaultCS, alias=httpsKeystorePassword})'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/trust-manager=httpsTM:add(key-store=httpsTS)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/server-ssl-context=https:add(key-manager=httpsKM,protocols=["TLSv1.3","TLSv1.2"],use-cipher-suites-order=false,cipher-suite-filter="TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256",cipher-suite-names="TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256",trust-manager=httpsTM,want-client-auth=true,authentication-optional=true)'

Add HTTP(S) Listeners

To add HTTP(S) listeners:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/http-listener=http:add(socket-binding="http", redirect-socket="https")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=https:add(socket-binding="https", ssl-context="https", max-parameters=2048)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Configure the Firewall

Open port 8080 and 8443 for incoming TCP traffic.

Open ports in RHEL / CentOS

CODE 
systemctl enable firewalld --now
firewall-cmd --set-default-zone=dmz
firewall-cmd --zone=dmz --permanent --add-port 8080/tcp
firewall-cmd --zone=dmz --permanent --add-port 8443/tcp
firewall-cmd --reload

Alternatively, you may open port 80 and port 443 and redirect traffic to 8080 and 8443 respectively.

Set up NAT in RHEL / CentOS

CODE 
systemctl enable firewalld --now
firewall-cmd --set-default-zone=dmz
firewall-cmd --zone=dmz --permanent --add-port 80/tcp
firewall-cmd --zone=dmz --permanent --add-port 443/tcp
firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=8080
firewall-cmd --permanent --add-forward-port=port=443:proto=tcp:toport=8443
firewall-cmd --reload

Use an HSM for TLS

You can store the private key for the TLS client certificate in an HSM instead for improved security and performance. WildFly contains the Sun PKCS11 provider which can be used to talk to the HSM using PKCS#11.

First, create a Sun PKCS11 configuration file according to the following Jinja2 template. Consult your HSM vendor for details on how to set PKCS#11 attributes.

/opt/wildfly/standalone/configuration/pkcs11.cfg

CODE 
name = HSM
library = {{ PKCS11_LIBRARY }}
slot = {{ SLOT_NUMBER }}
attributes(*, CKO_PUBLIC_KEY, *) = {
  CKA_TOKEN = false
  CKA_ENCRYPT = false
  CKA_VERIFY = true
  CKA_WRAP = false
}
attributes(*, CKO_PRIVATE_KEY, *) = {
  CKA_TOKEN = true
  CKA_PRIVATE = true
  CKA_SENSITIVE = true
  CKA_EXTRACTABLE = false
  CKA_DECRYPT = false
  CKA_SIGN = true
  CKA_UNWRAP = false
  CKA_DERIVE = false
}

Make the file readable by WildFly.

CODE 
chown wildfly:wildfly /opt/wildfly/standalone/configuration/pkcs11.cfg

Store the token PIN in your credential store.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=hsm,secret-value=123456)'

Create a provider loader and keystore for the Sun PKCS11 provider.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/provider-loader=pkcs11:add(class-names=[sun.security.pkcs11.SunPKCS11],path=pkcs11.cfg,relative-to=jboss.server.config.dir,module=sun.jdk)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKSInHSM:add(credential-reference={store=defaultCS, alias=hsm},type=PKCS11,providers=pkcs11)'

Generate a keypair and create a CSR using JBoss CLI. The CSR is stored in /opt/wildfly/standalone/configuration/keystore.

RSA key

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKSInHSM:generate-key-pair(alias=tlsKey0001, distinguished-name="CN=hostname", algorithm=RSA, key-size=2048)' 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKSInHSM:generate-certificate-signing-request(alias=tlsKey0001, path=keystore/csr.pem, relative-to=jboss.server.config.dir, signature-algorithm=SHA256withRSA)

Issue the certificate from your favourite CA and put the certificate chain next to the CSR. Then install it on the token:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKSInHSM:import-certificate(alias=tlsKey0001, path=keystore/chain.pem, relative-to=jboss.server.config.dir)'

Switch to the HSM keystore.

CODE 
/subsystem=elytron/key-manager=httpsKM:write-attribute(name=key-store,value=httpsKSInHSM)
/subsystem=elytron/key-manager=httpsKM:write-attribute(name=credential-reference,value={store=defaultCS, alias=hsm})

HTTP Protocol Behavior Configuration

The following shows an example HTTP protocol behavior configuration.

If you are using OCSP GET requests, setting URI encoding and allowing encoding for query and backslash are needed.

The commands below also ensure the address in the EJBCA WS WSDL matches the hostname and port the client uses to access the server.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.catalina.connector.URI_ENCODING:add(value="UTF-8")'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.tomcat.util.http.Parameters.MAX_COUNT:add(value=2048)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=webservices:write-attribute(name=wsdl-host, value=jbossws.undefined.host)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=webservices:write-attribute(name=modify-wsdl-address, value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Galleon Specific Configuration

The following covers Galleon-specific configurations.

Add Security domain to Undertow

Adds configuration missing in Galleon. This is not needed if the WildFly zip package was used.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/application-security-domain=other:add(security-domain=ApplicationDomain)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(info) This command can fail with a "Duplicate resource" error. If that happens, it is safe to ignore the error and skip this step.

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Add missing Remote EJB configuration

Adds configuration missing in Galleon. This is not needed if the WildFly zip package was used.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ejb3/service=remote:add(cluster=ejb,connectors=[http-remoting-connector],thread-pool-name=default)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(info) This command can fail with a "Duplicate resource" error. If that happens, it is safe to ignore the error and skip this step.

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Optional Configuration

The following sections cover optional configurations.

Remove Welcome Content

Removes the hardcoded welcome page in WildFly. This is not needed if Galleon was used.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/location="\/":remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=handler/file=welcome-content:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

You can also remove the actual files and save some disk space with:

CODE 
rm -rf /opt/wildfly/welcome-content/

Redirect to Application for Unknown URLs

Known URLs for EJBCA starts with /ejbca, /crls, /certificates or /.well-known (EST and ACME) according to the following example:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=redirect-to-app:add(redirect=true,target="/ejbca/adminweb/")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=redirect-to-app:add(priority=1,predicate="method(GET) and not path-prefix(/ejbca,/crls,/certificates,/.well-known) and not equals({\%{LOCAL_PORT}, 4447})")'

Enable HTTP Strict Transport Layer Security

The HTTP Strict-Transport-Security response header (HSTS) defined in RFC 6797 tells the browser to only access the server using HTTPS. If you are not serving any resources on the domain over HTTP such as OCSP responses,  you can enable this to improve security. Start off with a small max-age value (such as 60 seconds) and then gradually increase.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/response-header=hsts:add(header-name="Strict-Transport-Security",header-value="max-age=31536000")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=hsts:add()'

You should also redirect any HTTP traffic to HTTPS. The example assumes port 80 is used for HTTP,  port 443 for HTTPS and that the server can be accessed using the domain name example.com. It is also assumed that there is optional client certificate authentication on port 443 similar to 2-port separation. In the case of 3-port separation, traffic should be redirected to port 8442.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=http-to-https:add(redirect="true",target="https://example.com:443%U%q")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=http-to-https:add(predicate="equals(%p,80)")'

URL Rewriting

URL rewriting allows you to serve CRLs, CA certificates and OCSP responses on your own URLs. This can be done using rewrite rules in Undertow.

URL Rewriting for the CRL Store Servlet

Since EJBCA 7.2, the ability to customize the URL for the CRL store servlet at compile time has been removed. For more information, see ECA-7059 and the EJBCA 7.2 Upgrade Notes.

However, the same result can be achieved by configuring Undertow. As an example, to allow a client to download CRLs from the URL /ejbca/crls/ instead of /ejbca/publicweb/crls/, add the following configuration:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=crl-rewrite:add(target="/ejbca/publicweb/crls/$${1}")'
/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=undertow/server=default-server/host=default-host/filter-ref=crl-rewrite:add(predicate=\"method(GET) and regex('/crls/(.*)')\")"

Or if you want to link to a specific CRL directly, go to /ejbca/publicweb/crls/search.cgi, make a note of the appropriate iHash value, and then add a URL rewrite according to the following example:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=cdp-RootCA:add(target="/ejbca/publicweb/crls/search.cgi?iHash=Aj2kgEB646IWuipyNwa970dIzOs")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=cdp-RootCA:add(predicate="method(GET) and path(/crl/RootCA.crl)")'

URL Rewriting for the Certstore Servlet

Since EJBCA 7.2, the ability to customize the URL for the Certstore servlet at compile time has been removed. For more information, see ECA-7059 and the EJBCA 7.2 Upgrade Notes.

However, the same result can be achieved by configuring Undertow. As an example, to allow a client to download CA certificates from the URL /ejbca/certificates/ instead of /ejbca/publicweb/certificates/, add the following configuration:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=certs-rewrite:add(target="/ejbca/publicweb/certificates/$${1}")'
/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=undertow/server=default-server/host=default-host/filter-ref=certs-rewrite:add(predicate=\"method(GET) and regex('/certificates/(.*)')\")"

Or if you want to link to a specific CA certificate directly, go to /ejbca/publicweb/certificates/search.cgi, make a note of the appropriate iHash value, and then add a URL rewrite according to the following example:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=aia-RootCA:add(target="/ejbca/publicweb/certificates/search.cgi?iHash=Aj2kgEB646IWuipyNwa970dIzOs")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=aia-RootCA:add(predicate="method(GET) and path(/aia/RootCA.cer)")'

URL Rewriting for the OCSP Responder

All OCSP responses are served from the same URL in EJBCA. To access the OCSP responder on the somewhat more succinct /ocsp instead of /ejbca/publicweb/status/ocsp, reconfigure Undertow as follows:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/rewrite=rewrite-ocsp:add(target="/ejbca/publicweb/status/ocsp")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=rewrite-ocsp:add(predicate="path(/ocsp) and method(GET,POST)")'

Enable OCSP Revocation Checking

WildFly can check the validity of client certificates against the OCSP responder defined by the certificate's AIA extension:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/trust-manager=httpsTM:write-attribute(name=ocsp, value={})'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Remove the ExampleDS Datasource

You can remove the ExampleDS datasource as it is not being used. This is not needed if Galleon was used.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ee/service=default-bindings:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect 'data-source remove --name=ExampleDS'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Remove Unused Subsystems and Extensions

Optionally remove the unused subsystems and extensions. This is not needed if Galleon was used.

If you used the Jakarta EE Full & Web Distribution zip package:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=jdr:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=sar:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=jmx:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=pojo:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=microprofile-jwt-smallrye:remove()' 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ee-security:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=microprofile-opentracing-smallrye:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=distributable-web:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/jdbc-driver=h2:remove()'

/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.microprofile.jwt-smallrye:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.clustering.web:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.microprofile.opentracing-smallrye:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=health:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=metrics:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.health:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.metrics:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.jboss.as.jdr:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.jboss.as.jmx:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.jboss.as.sar:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.jboss.as.pojo:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.ee-security:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.request-controller:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect '/extension=org.wildfly.extension.security.manager:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Remove AJP

Clean up all AJP related configuration if you are not using it.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/socket-binding=ajp:remove()'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Enable AJP Connector

Enabling the AJP connector is only needed if you terminate the TLS connection at a proxy (such as Apache or nginx) running in front of WildFly:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/ajp-listener=ajp-listener:add(socket-binding=ajp, scheme=https, enabled=true)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Add a Request Limiter

You can limit the number of concurrent connections by adding a request limiter in Undertow. For example, to allow 100 connections to be processed at the same time, and allow up to 300 connections to be queued before new connections are rejected:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/request-limit=ejbca-request-limiter:add(max-concurrent-requests=100,queue-size=300)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=ejbca-request-limiter:add(predicate=path-prefix(/ejbca)'

Restrict Access to Services

You can whitelist IP addresses or block access to some services completely using predicates and handlers in Undertow.

For example, to only allow access to the CA web from localhost:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/expression-filter=local-only:add(expression="ip-access-control(acl={127.0.0.0/8 allow})")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=local-only:add(predicate="path-prefix(/ejbca/adminweb)")'

To block access to the public web pages and the EJBCA documentation:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/configuration=filter/expression-filter=not-found:add(expression="response-code(404)")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/host=default-host/filter-ref=not-found:add(predicate="path-prefix(/ejbca/enrol,/ejbca/retrieve,/ejbca/inspect,/ejbca/doc) or path(/ejbca)")'

Add Support for Sending Email

To add support for sending email using an SMTP smarthost, configure EjbcaMail. Specify the hostname, address, port and SMTP credentials according to the following example:

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=smtpPassword, secret-value="foo123")'
/opt/wildfly/bin/jboss-cli.sh --connect '/socket-binding-group=standard-sockets/remote-destination-outbound-socket-binding=ejbca-mail-smtp:add(port="465", host="my.mail.server")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=mail/mail-session="java:/EjbcaMail":add(jndi-name=java:/EjbcaMail, from=noreply@ejbca.org)' 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=mail/mail-session="java:/EjbcaMail"/server=smtp:add(outbound-socket-binding-ref=ejbca-mail-smtp, tls=true, username=smtpuser, credential-reference={store=defaultCS, alias=smtpPassword})'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

Only Deploy at Startup

Historically application servers are really bad at cleaning up memory from previous deployments and hot (re-)deploy is discouraged in production. To avoid manual deployment with the management interface, we can specify that the deployment directory should be scanned once at application server startup by setting the scan-interval to 0. This also prevents an attacker from loading a malicious JAR file by dropping it in the deployments directory.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-interval,value=0)'

Increase the Deployment Timeout

If you are using HSMs with smart card authentication or if the database needs to reindex when WildFly boots, you may have to increase the deployment timeout to be able to deploy EJBCA correctly. The deployment timeout is specified in seconds, the command below sets it to 5 minutes.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=deployment-scanner/scanner=default:write-attribute(name=deployment-timeout,value=300)'

Disable Management Web Console

If you only plan on using the JBoss CLI anyway there is little reason to keep this around.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/core-service=management/management-interface=http-interface:write-attribute(name=console-enabled,value=false)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Increase the Maximum Upload Size

Increase the maximum size of POST requests to 25 MB. This may be required if you need to upload large domain blocklists, zip packages with profiles, statedumps, etc. It may also be required for publishing relatively large CRLs to an external VA.

If 3-port separation is used, increase the maximum upload size for the httpspriv HTTPS listener.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=httpspriv:write-attribute(name=max-post-size,value=25485760)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

If 2-port separation is used, increase the maximum upload size for the https HTTPS listener instead.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=undertow/server=default-server/https-listener=https:write-attribute(name=max-post-size,value=25485760)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

Enable WildFly Audit Logging

WildFly can audit log changes made to the management model and output audit log events in JSON format to the file /opt/wildfly/standalone/data/audit-log.log. Audit logging is disabled by default. To enable it, run:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/core-service=management/access=audit/logger=audit-log:write-attribute(name=enabled,value=true)'

Remove WildFly Audit Logging

You may remove the WildFly audit logging configuration completely if you are not using it.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect '/core-service=management/access=audit:remove()'

Configure Certificate Enrollment With ACME

The Elytron subsystem in WildFly can enroll for TLS server certificates using ACME. If you enroll from EJBCA, see EJBCA documentation on how to enable and configure ACME.

To prove ownership of the domain name in the CSR, WildFly must be able to serve an HTTP challenge over port 80 put in the server root directory. The easiest way to get this to work is to WildFly 32#2portseparation.

  1. If the ACME server has a server certificate that chains up to an internal root not trusted by Java you need to manually add it to Java's truststore.

    Add a CA to the Java truststore in CentOS / RHEL

    CODE 
    keytool -importcert -noprompt -trustcacerts -alias internal-root -file InternalRoot.pem -keystore /etc/pki/java/cacerts -storepass changeit

  2. Create a keystore where the keypair of the ACME account will be stored.

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add-alias(alias=accountsPassword, secret-value="foo123")'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=accountsKS:add(path=keystore/accounts.p12,relative-to=jboss.server.config.dir,credential-reference={store=defaultCS, alias=accountsPassword},type=PKCS12)'

  3. Define the ACME directory to use. If you are enrolling directly against an EJBCA server, use something like https://my.ca/ejbca/acme/<alias>/directory .

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/certificate-authority=AcmeCA:add(url="<ACME_DIRECTORY_URL>")'

  4. Register an ACME account with the CA. The email address may be used by the CA to send announcements and warn about certificates that are about to expire.

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/certificate-authority-account=AcmeAccount:add(certificate-authority=AcmeCA,alias=https,key-store=accountsKS,contact-urls=[mailto:admin@example.com])'

  5. Enroll for a certificate to test the configuration. Replace <HOSTNAME> with the hostname of your machine. You can specify multiple hostnames by separating them with a comma.

    Enroll with an RSA keypair

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKS:obtain-certificate(alias=https,domain-names=[<HOSTNAME1>],certificate-authority-account=AcmeAccount,agree-to-terms-of-service)'

    Enroll with an EC keypair

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/key-store=httpsKS:obtain-certificate(alias=https,domain-names=[<HOSTNAME1>],algorithm=EC,key-size=256,certificate-authority-account=AcmeAccount,agree-to-terms-of-service)'

  6. Create a script to automatically renew the certificate when its about to expire.

    1. Install jq.

      Install jq in CentOS / RHEL

      CODE 
      yum install jq -y

    2. Create the script called renew-wildfly-certificate.sh and put it in /etc/cron.daily to make it run on a daily basis. Adjust the parameters in the script to match your configuration.

      /etc/cron.daily/renew-wildfly-certificate.sh

      BASH 
      #!/bin/sh
#
#  Renew the WildFly TLS server certificate using ACME.
#  Assumes an ACME account has been configured in Elytron.
#  Requires 'jq' to be installed.
#

# The number of days before expiry where renewal should be attempted.
days=30
# Specify the type of keypair to generate. Possible values: [ "secp256r1", "RSA2048" ]
key_specification="RSA2048"
# The domain name(s) to put in the CSR. Separate with comma ','.
domains="domain1.com,domain2.com"
# The keystore alias of the certificate to renew
alias="https"
# The name of the ACME account in standalone.xml
account="AcmeAccount"

output=$(/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=elytron/key-store=httpsKS:should-renew-certificate(alias=$alias,expiration=$days)" --output-json)
logger "$output"
renew=$(echo "$output" | jq '.result["should-renew-certificate"]')
if [ "$renew" = "true" ]; then
    logger "Attemping to renew domains [$domains]."
    if [ "$key_specification" = "secp256r1" ]; then
        output=$(/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=elytron/key-store=httpsKS:obtain-certificate(alias=$alias,domain-names=[$domains],algorithm=EC,key-size=256,certificate-authority-account=$account,agree-to-terms-of-service)" --output-json)
        logger "$output"
    fi
    if [ "$key_specification" = "RSA2048" ]; then
        output=$(/opt/wildfly/bin/jboss-cli.sh --connect "/subsystem=elytron/key-store=httpsKS:obtain-certificate(alias=$alias,domain-names=[$domains],certificate-authority-account=$account,agree-to-terms-of-service)" --output-json)
        logger "$output"
    fi
fi

    3. Make the script executable.

      CODE 
      chmod +x /etc/cron.daily/renew-wildfly-certificate.sh

Start WildFly on System Boot

To make EJBCA available automatically after a system restart, use systemd.

CODE 
systemctl enable wildfly

Performance Tuning

WilfFly performs well for most use cases using the default WildFly configuration. You only need to look at the below parameters if you experience issues that you think can be tuned.

The following section gives some hints on variables to configure in WildFly for tuning performance. The best setup varies hugely between different use cases and need to be manually fine-tuned. However, the "default" configuration would typically be a good starting point. You must also  tune Java memory usage, typically heap (RAM), for EJBCA instances under high load,  at least 4 GB is a good starting point.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=io/worker=default/:write-attribute(name=task-core-threads,value=25)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=io/worker=default/:write-attribute(name=task-max-threads,value=100)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=io/worker=default/:write-attribute(name=io-threads,value=100)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ejb3/strict-max-bean-instance-pool=slsb-strict-max-pool:undefine-attribute(name=derive-size)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ejb3/strict-max-bean-instance-pool=slsb-strict-max-pool:write-attribute(name=max-pool-size, value=32)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=ejb3/thread-pool=default:write-attribute(name="max-threads", value=100)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads/:write-attribute(name=max-pool-size,value=150)'
/opt/wildfly/bin/jboss-cli.sh --connect ':reload'

(warning) Wait for the reload to complete by checking the server log or the result of :read-attribute(name=server-state) before continuing.

Create a Snapshot of the Configuration

Create a snapshot of the current configuration to make sure you can revert back to a working state.

BASH 
/opt/wildfly/bin/jboss-cli.sh --connect ':take-snapshot(name="Initial configuration")'
cp /opt/wildfly/standalone/configuration/standalone.xml /opt/wildfly/standalone/configuration/standalone.xml.backup

Create a Terminal Alias for Reading the Log File

EJBCA is logging all actions to the WildFly log file located in /opt/wildfly/standalone/log/server.log. It is often useful to be able to quickly filter and inspect the latest log lines. If you are using Fish you can add the following function to your config.fish:

BASH 
function wflog --description 'Tail and optionally filter the WildFly log file'
    tail -f /opt/wildfly/standalone/log/server.log | \
        awk '/TRACE/ {print "\033[93m" $0 "\033[39m"}
             /DEBUG/ {print "\033[0;32m" $0 "\033[39m"}
             /INFO/ {print "\033[0;34m" $0 "\033[39m"}
             /WARN/ {print "\033[0;33m" $0 "\033[39m"}
             /ERROR/ {print "\033[0;31m" $0 "\033[39m"}
             /SEVERE/ {print "\033[1;31m" $0 "\033[39m"}
             !/(TRACE|DEBUG|INFO|WARN|ERROR|SEVERE)/ {print "\033[93m" $0 "\033[39m"}' | \
        grep --line-buffered --color=never -E "$argv[1]"
end

Or if you are using Bash, add this to your .bashrc:

BASH 
wflog() { 
    tail -f /opt/wildfly/standalone/log/server.log | \
        awk '/TRACE/ {print "\033[93m" $0 "\033[39m"}
             /DEBUG/ {print "\033[0;32m" $0 "\033[39m"}
             /INFO/ {print "\033[0;34m" $0 "\033[39m"}
             /WARN/ {print "\033[0;33m" $0 "\033[39m"}
             /ERROR/ {print "\033[0;31m" $0 "\033[39m"}
             /SEVERE/ {print "\033[1;31m" $0 "\033[39m"}
             !/(TRACE|DEBUG|INFO|WARN|ERROR|SEVERE)/ {print "\033[93m" $0 "\033[39m"}' | \
        grep --line-buffered --color=never -E "$argv[1]"
}

Clear Command Line History

Clear the command line history to prevent accidental viewing of passwords put into the credential store.

BASH 
history -c

Next Step: Deploying EJBCA

For instructions on how to build and deploy EJBCA, see Deploying EJBCA.

Debug EJBCA

The following explains the configuration options in WildFly for troubleshooting EJBCA.

Switch to Debug Logging Globally

To enable debug logging globally, if you need to troubleshoot, follow these steps.

  1. Make a note of the current log level for the packages org.cesecore and org.ejbca.

    CODE 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore:read-attribute(name=level)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca:read-attribute(name=level)'

  2. Switch to debug logging.

    BASH 
    /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca:write-attribute(name=level, value=DEBUG)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore:write-attribute(name=level, value=DEBUG)'

Once you are done troubelshooting, switch back to the log level you used previously. Note that having debug logging enabled globally will produce a lot of output, avoid using this configuration in production and consider enabling debugging for individual packages instead.

Switch to Debug Logging for Individual Packages

EJBCA is divided into different packages, and instead of raising the log level globally, you can be a bit more surgical in your approach and pick individual packages to troubleshoot. For available packages and classes, you can dynamically generate a list of JBoss CLI commands for enabling debug logging based on import statements and package declarations in the source code, with the most "popular" packages first:

CODE 
grep -REh "^(package|import) (org.ejbca|org.cesecore|org.jitsi)" /opt/ejbca/modules | grep -v '*' | sed -E 's/(package|import) //' | sed -E 's/;\s*//' | awk '{n=split($0,c,".")};{for(i=1;i<=n;i++){for(j=1;j<=i;j++)printf("%s.",c[j]);printf("\n")}}' | sed -E 's/\.$//' | sort | uniq -c | sort -nr | awk '{if(NR>3) print "/opt/wildfly/bin/jboss-cli.sh --connect \'/subsystem=logging/logger="$2":add(level=DEBUG)\'"}'

If you want something more flashy, you can pipe the output to something like fzf, allowing you to filter and select the package or class name from a list. For example, add the following to your config.fish:

CODE 
function wflogging --description 'Configure logging for various packages and classes in WildFly using fuzzy finding'
    grep -REh "^(package|import) (org.ejbca|org.cesecore|org.jitsi)" /opt/ejbca/modules | \
        grep -v '*' | \
        sed -E 's/(package|import) //' | \
        sed -E 's/;\s*//' | \
        awk '{n=split($0,c,".")};{for(i=1;i<=n;i++){for(j=1;j<=i;j++)printf("%s.",c[j]);printf("\n")}}' | \
        sed -E 's/\.$//' | \
        sort | uniq -c | sort -nr | \
        awk '{if(NR>3) print $2}' | \
        fzf --margin 1% --border=rounded --header 'Package / Class' \
            --bind "ctrl-a:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:add(level=INFO)')+refresh-preview" \
            --bind "ctrl-r:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:remove')+refresh-preview" \
            --bind "ctrl-t:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:write-attribute(name=level,value=TRACE)')+refresh-preview" \
            --bind "ctrl-d:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:write-attribute(name=level,value=DEBUG)')+refresh-preview" \
            --bind "ctrl-i:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:write-attribute(name=level,value=INFO)')+refresh-preview" \
            --bind "ctrl-w:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:write-attribute(name=level,value=WARN)')+refresh-preview" \
            --bind "ctrl-e:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger={}:write-attribute(name=level,value=ERROR)')+refresh-preview" \
            --bind "alt-t:execute-silent(/opt/wildfly/bin/jboss-cli.sh --connect ':take-snapshot(name=wflogging_)')" \
            --bind "alt-r:execute(sudo mv /opt/wildfly/standalone/configuration/standalone.xml /opt/wildfly/standalone/configuration/standalone.xml.bak && sudo cp /opt/wildfly/standalone/configuration/standalone_xml_history/snapshot/wflogging_standalone.xml /opt/wildfly/standalone/configuration/standalone.xml && /opt/wildfly/bin/jboss-cli.sh --connect ':shutdown(restart=true)')" \
            --preview "printf \"Current logging configuration for {}\n\n\" && /opt/wildfly/bin/jboss-cli.sh --output-json --connect '/subsystem=logging/logger={}:read-resource'"
end

Or if you are using Bash, add this to your .bashrc:

CODE 
wflogging() {
    grep -REh "^(package|import) (org.ejbca|org.cesecore|org.jitsi)" /opt/ejbca/modules | \
        grep -v '*' | \
        sed -E 's/(package|import) //' | \
        sed -E 's/;\s*//' | \
        awk '{n=split($0,c,".")};{for(i=1;i<=n;i++){for(j=1;j<=i;j++)printf("%s.",c[j]);printf("\n")}}' | \

This will add a command called wflogging, which opens fzf where you can select a class or package name in a list. Press Alt+T to take a snapshot of the existing log configuration, Ctrl + A to add logging, Ctrl + R to remove logging, and Ctrl + D to enable debugging for the selected item. The current configuration in the application server is shown in the preview window on the right.

Log Requests and Responses for the WebService API

To log the SOAP messages received by and sent from EJBCA:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.cxf.logging.enabled:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.apache.cxf.services:add(level=INFO)'
systemctl restart wildfly

To remove the configuration when you are done:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=org.apache.cxf.logging.enabled:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.apache.cxf.services:remove'
systemctl restart wildfly

Log Requests and Responses for the EJBCA REST API

There is a servlet filter bundled with the EJBCA REST API which can be used to dump the full request and response.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.ui.web.rest.api.config.RestLoggingFilter:add(level=TRACE)'

Log Requests and Responses for EST

There is a servlet filter bundled with the EJBCA REST API which can be used to dump the full request and response.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.ui.web.protocol.EstLoggingFilter:add(level=TRACE)'

Log Requests for CMP

CmpMessageDispatcherSessionBean logs any CMP messages being sent from the CMP client on debug level. The whole ASN.1 is logged on trace level.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.core.protocol.cmp.CmpMessageDispatcherSessionBean:add(level=TRACE)'

Log Requests and Responses for the ACME API

There is a servlet filter bundled with the EJBCA ACME implementation which can be used to dump the full request and response.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.ui.web.protocol.acme.web.AcmeLoggingFilter:add(level=DEBUG)'

Enable Debugging for Microsoft Autoenrollment

To troubleshoot Microsoft Autoenrollment, enable debugging for the MSAE package.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.msae:add(level=DEBUG)'

Monitor the Peer Systems Connections Pool

Each peer connector maintains a pool of TLS connections. Each request will occupy one connection from the pool, and requests are delayed if the pool is empty. If you suspect that more pooled connections are needed:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.peerconnector.ra.PeerRaThrottleCounter:add(level=DEBUG)'

Debug P11Ng

P11Ng is responsible for communicating with the HSM using PKCS#11. If you need to troubleshoot HSM-related issues, you may enable debugging for P11Ng as follows:

Older installations may use the Sun PKCS#11 instead of P11Ng, in which case these instructions do not apply.

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.keys.token.p11ng:add(level=DEBUG)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.ejbca.ui.p11ngcli:add(level=DEBUG)'
# Optionally add this logging item for in-depth PKCS#11 troubleshooting
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.cesecore.keys.token.p11ng.provider.CryptokiDevice:add(level=TRACE)'

Enable Hibernate Statistics

Hibernate is the ORM library used by EJBCA to create SQL queries. You can enable Hibernate statistics to get the SQL query, as well as the time it takes to execute it, written in the server log.

Hibernate statistics are quite verbose and there may be database-specific tools better suited to troubleshoot database performance, however if you want to enable it:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads/statistics=pool:write-attribute(name=statistics-enabled,value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads/statistics=jdbc:write-attribute(name=statistics-enabled,value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.generate_statistics:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.show_sql:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.format_sql:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.use_sql_comments:add(value=true)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.hibernate.stat:add(level=DEBUG)'
systemctl restart wildfly

To remove the configuration:

CODE 
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=logging/logger=org.hibernate.stat:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.use_sql_comments:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.format_sql:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.show_sql:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/system-property=hibernate.generate_statistics:remove'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads/statistics=jdbc:write-attribute(name=statistics-enabled,value=false)'
/opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=datasources/data-source=ejbcads/statistics=pool:write-attribute(name=statistics-enabled,value=false)'
systemctl restart wildfly

Enable Profiling Using Glowroot

  1. Download Glowroot and put it in your WildFly directory.

    CODE 
    wget https://github.com/glowroot/glowroot/releases/download/v0.13.6/glowroot-0.13.6-dist.zip -O /tmp/glowroot.zip
unzip -q /tmp/glowroot.zip -d /opt/wildfly
chown -R wildfly:wildfly /opt/wildfly/glowroot


  2. Register Glowroot as a Java agent and restart WildFly.

    CODE 
    sed -i '/-Djdk.tls.ephemeralDHKeySize=2048/ a \ \ \ JAVA_OPTS=\"$JAVA_OPTS -javaagent:/opt/wildfly/glowroot/glowroot.jar"' /opt/wildfly/bin/standalone.conf
systemctl restart wildfly
  3. Glowroot should now be availble on http://localhost:4000.
