Overview
We create a simple systemd Type=oneshot unit file that delegates the work of starting and stopping the instance to the System V wrappers shipped with EAP installation bundle.
systemd File Locations
We adapted the installation procedure after an ActiveMQ installation procedure that recommended placing files in /usr/lib/systemd/scripts and /usr/lib/systemd/system. However, a better location seems to be /etc/systemd/... More research is needed, the results will go here systemd Concepts#Unit_File_Location.
Install the Pre-Packaged System V Startup Scripts into Standard systemd Location
Copy the pre-packaged System V startup scripts (jboss-as-domain.sh, jboss-as-standalone.sh) from $JBOSS_HOME/bin/init.d into /usr/lib/systemd/scripts.
Perform the following operations as "root", re-name the scripts as indicated below.
For a standalone installation, name the script jboss.
cp $JBOSS_HOME/bin/init.d/jboss-as-standalone.sh /usr/lib/systemd/scripts/jboss
For a domain installation, name the script jboss-host-controller, regardless of whether we're configuring to start the domain controller or a subordinate host controller. This is because on the domain controller host, the domain controller process and the host controller process coincide.
cp $JBOSS_HOME/bin/init.d/jboss-as-domain.sh /usr/lib/systemd/scripts/jboss-host-controller
Customize the WildFly Startup Wrapper
Create the Unit File
Create the /usr/lib/systemd/system/eap.service unit file:
[Unit] Description=EAP Service After=network.target [Service] Type=oneshot ExecStart=/usr/lib/systemd/scripts/jboss-host-controller start ExecStop=/usr/lib/systemd/scripts/jboss-host-controller stop RemainAfterExit=yes [Install] WantedBy=multi-user.target
Notify systemd of the existence of the new unit file
systemctl daemon-reload
Enable at Boot
systemctl enable eap.service
