[Install]
WantedBy=multi-user.target

When you are finished, save and close the file.

Next, reload the systemd daemon so that it knows about our service file:

sudo systemctl daemon-reload

Now enable the service

sudo systemctl enable liferay

Start the Liferay service by typing:

sudo systemctl start liferay

Double check that it started without errors by typing:

sudo systemctl status liferay

Thank you very much! Helped me a lot!

It works

I can't start the service I got this message :
Process: 8712 ExecStart=/var/www/vhosts/themeray.com/liferay-portal-6.2-ce-ga6/tomcat-7.0.62/bin/startup.sh (code=exited, status=203/EXEC)
liferay.service: Failed to execute command: Permission denied

Did you set the right user/group?
