I have had many clients ask me if Liferay has management scripts for Apache Tomcat. While Liferay doesn't officially recommend any particular way to start/stop Tomcat, I have found this works really well for me on client sites.
You’ll need to make the script executable by running the chmod command:
sudo chmod 755 /etc/init.d/liferay
The last step is actually linking this script to the startup folders with a symbolic link. Execute these two commands and we should be on our way.
sudo ln -s /etc/init.d/liferay /etc/rc1.d/K99liferay
sudo ln -s /etc/init.d/liferay /etc/rc2.d/S99liferay
