Customize WildFly Startup Wrapper
Overview
This procedure is used for both System V and systemd, as both systems use the same wrapper scripts. For context, see Start WildFly as a System V Service on Linux and Start WildFly as a systemd Service on Linux.
Customize the Wrapper
Domain Controller High Availability Considerations
If you're building a host controller that is expected to fail over among multiple HA domain controllers, increase the STARTUP_WAIT (see HA Domain Controller Failover Process for details).
Backup Domain Controller Considerations
If you're building a backup domain controller you will need to add this into jboss-host-controller}:
JBOSS_BACKUP_DOMAIN_CONTROLLER=true
and then add this to the start line:
...
local backup_option
${JBOSS_BACKUP_DOMAIN_CONTROLLER} && backup_option="--backup"
if [ ! -z "$JBOSS_USER" ]; then
if [ -r /etc/rc.d/init.d/functions ]; then
daemon [...] --host-config=$JBOSS_HOST_CONFIG ${backup_option} [...]
else
su [...] --host-config=$JBOSS_HOST_CONFIG ${backup_option}" [...]
fi
fi
...
Optional
If you deleted domain.xml, you will also need to set:
JBOSS_DOMAIN_CONFIG=domain.cached-remote.xml
but this is undocumented, so it's probably best NOT to remove domain.xml and leave JBOSS_DOMAIN_CONFIG definition in jboss-host-controller alone.
Permissions
Adjust permissions so the init system can execute the scripts.
chmod a+rx ./jboss chmod a+rx ./jboss-host-controller
