Running Liferay as a Service

 Running Liferay as a Service

How to run Liferay as a Service and make it auto-started on system reboot


Introduction


Sometimes servers hosting Liferay can be restarted. For a higher availability of the Liferay portal we need to make sure that Liferay is also started automatically during the system start. To achieve this - Liferay can be run as a service configured to auto-start.


Configuration


  1. Define Liferay Service Configuration File


To define a service for Liferay - create a liferay.service file inside /usr/lib/systemd/system directory as root user:


sudo su 

cd /usr/lib/systemd/system

touch liferay.service

nano liferay.service


with the following content:


[Unit]

Description=Liferay Service

After=network.target


[Service]

Type=forking

User=user

Group=user

Environment=JAVA_HOME=[JAVA_HOME]

Environment=CATALINA_PID=[LIFERAY-PATH]/tomcat[-x.x.x]/temp/tomcat.pid

Environment=CATALINA_HOME=[LIFERAY-PATH]/tomcat[-x.x.x]

Environment=CATALINA_BASE=[LIFERAY-PATH]/tomcat[-x.x.x]

Environment=CATALINA_TMPDIR=[LIFERAY-PATH]/tomcat[-x.x.x]/temp

Environment='CATALINA_OPTS=-Dfile.encoding=UTF-8 -Djava.locale.providers=JRE,COMPAT,CLDR -Djava.net.preferIPv4Stack=true -Duser.timezone=GMT -Xms8g -Xmx8g -XX:MaxNewSize=2g -XX:MaxMetaspaceSize=1g -XX:MetaspaceSize=1g -XX:NewSize=2g -XX:SurvivorRatio=16 -XX:InitialCodeCacheSize=64m -XX:ReservedCodeCacheSize=96m -XX:TargetSurvivorRatio=50 -XX:MaxTenuringThreshold=15'

ExecStart=/bin/bash [LIFERAY-PATH]/tomcat[-x.x.x]/bin/startup.sh

ExecStop=/bin/bash [LIFERAY-PATH]/tomcat[-x.x.x]/bin/shutdown.sh


[Install]

WantedBy=multi-user.target


Specify Java Home [JAVA_HOME] and Liferay path [LIFERAY-PATH].

Define the user and group under which the service should be started.


Note: the WantedBy=multi-user.target directive inside [Install] sections makes the service auto-started on reboot



  1. Enable Liferay Service


Reload the systemd daemons to pick up the new service file:


sudo systemctl daemon-reload


Run the following command to enabled the service:


sudo systemctl enable liferay.service



  1. Run Liferay Service


Run the following command to start the Liferay Service:


sudo systemctl start liferay.service


Restart the system to make sure service is started properly:


sudo reboot


Enjoy 😏
