Start WildFly as a System V Service on Linux

Internal

• Start WildFly as a Service on Linux

Overview

This procedure applies when the installation was done by unzipping or via the installer. This does not apply to an RPM installation.

The procedure is similar for standalone mode and domain mode. The only difference is the name of the original startup scripts (jboss-as-standalone.sh, jboss-as-domain.sh below).

Note that this procedure differs slightly from the manual procedure (https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.4/html/Installation_Guide/sect-Service_Configuration.html#Install_JBoss_Enterprise_Application_Platform_6_Red_Hat_Enterprise_Linux_Service). This procedure is simpler, and does not require supplementary configuration files in /etc.

Locate the Pre-Packaged Startup Scripts

They are available in $JBOSS_HOME/bin/init.d as jboss-as-domain.sh and jboss-as-standalone.sh.

Install the Scripts into their Standard Locations

Perform the following operations as "root", name the scripts accordingly:

For a standalone installation, name the script jboss.

cp $JBOSS_HOME/bin/init.d/jboss-as-standalone.sh  /etc/init.d/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  /etc/init.d/jboss-host-controller

Configure the Startup Script from init.d

Add at the top of the file:

JBOSS_HOME=/home/eap/EAP-6.4.0
JBOSS_USER=eap
#
# The amount of time to wait for startup
#
STARTUP_WAIT=30
#
# The amount of time to wait for shutdown
#
SHUTDOWN_WAIT=30
#
# Location to keep the console log
#
JBOSS_CONSOLE_LOG=${JBOSS_HOME}/domain/log/console.log
[ ! -d ${JBOSS_HOME}/domain/log ] && { mkdir -p ${JBOSS_HOME}/domain/log; chown ${JBOSS_USER} ${JBOSS_HOME}/domain/log; chmod a+rx ${JBOSS_HOME}/domain/log; }

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
  ...
<pre>

===Optional===

If you deleted <tt>domain.xml</tt>, you will also need to set:

<pre>
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

Then adjust permissions:

chmod a+rx ./jboss
chmod a+rx ./jboss-host-controller 

Add the Startup Script As a Service

chkconfig --add jboss|jboss-host-controller
chkconfig --list jboss|jboss-host-controller
chkconfig --level 2345 jboss|jboss-host-controller on

The Line that Starts The Process

...
su - $JBOSS_USER -c "LAUNCH_JBOSS_IN_BACKGROUND=1 JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT --domain-config=$JBOSS_DOMAIN_CONFIG --host-config=$JBOSS_HOST_CONFIG" 2>&1 > $JBOSS_CONSOLE_LOG &
