Several JBoss instances in the same server

You can have several JBoss instances in the same server, and only need to modify some default JBoss ports.

• Edit $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/server.xml and change these ports: 8080, 8009 and 8443.
• Edit $JBOSS_HOME/server/default/conf/jboss-service.xml and change these ports: 8083, 4444, 4445,4446, 1098 and 1099.
• Edit $JBOSS_HOME/server/default/deploy/jms/uil2-service.xml and change this port: 8093.
• Edit $JBOSS_HOME/server/default/deploy/ejb3.deployer/META-INF/jboss-service.xml and change this port: 3873.
• Edit $JBOSS_HOME/bin/shutdown.sh and add to the last "localhost" line the new HTTP port.

# Execute the JVM
exec "$JAVA" \
    $JAVA_OPTS \
    -classpath $JBOSS_CLASSPATH \
    org.jboss.Shutdown localhost 8081 "$@"

The simpliest way is increasing the default port by +1, keeping in mind the pairs 4444-4446 and 1098-1099 where your have to add +3,+2 because are consecutives.

Following this advice the news port will be:

• 8080 -> 8081 (Put this one in the shutdown.sh script)
• 8009 -> 8010
• 8443 -> 8444
• 8083 -> 8084
• 4444 -> 4447 (+3 because consecutive)
• 4445 -> 4448 (+3 because consecutive)
• 4446 -> 4449 (+3 because consecutive)
• 1098 -> 1100 (+2 because consecutive)
• 1099 -> 1101 (+2 because consecutive)
• 8093 -> 8094
• 3873 -> 3874
