    Is this a good method to start Jboss on Linux with systemd?

      This is a copy of Is this a good method to start Jboss on Linux with systemd? However do to lack of reactions I do a re post here.

       

      I have written a systemd service to start Jboss on Linux and I wonder if there is a more elegant solution. Are there any disadvantages for the method I have chosen? The configuration xml secure_eap_1.xml is a copy of the standalone.xml (or a copy of one of the other templates). Every Jboss AS instance has it own Jboss installation tree in this example.

       

      The systemd unit file: secure_eap_1.service

       

      [Unit]

      Description=JBoss AS secure_eap_1

      After=network.target

       

      [Service]

      EnvironmentFile=/appl/jboss/scripts/secure_eap_1.cfg

      ExecStart=/bin/sh -c '${JAVA} ${JBOSS_MODE} ${GC_OPTS} ${JAVA_OPTS} ${JBOSS_OPTS} ${JBOSS_CFG}'

      TimeoutStartSec=120

      TimeoutStopSec=300

      SuccessExitStatus=143

      Type=simple

      User=jboss

      Group=jboss

       

      [Install]

      WantedBy=default.target

       

      The configuration file with the environment settings in /appl/jboss/scripts/secure_eap_1.cfg

       

      # JAVA version

      JAVA_HOME=/usr/lib/jvm/jre-1.8.0
