Ubuntu start Tomcat on boot

Automatic Starting

To make tomcat automatically start when we boot up the computer, you can
add a script to make it auto-start and shutdown.

sudo vi /etc/init.d/tomcat

Now paste the following content:

# Tomcat auto-start
#
# description: Auto-starts tomcat
# processname: tomcat
# pidfile: /var/run/tomcat.pid

export JAVA_HOME=/usr/lib/jvm/java-6-sun

case $1 in
start)
sh /usr/local/tomcat/bin/startup.sh
;;
stop)
sh /usr/local/tomcat/bin/shutdown.sh
;;
restart)
sh /usr/local/tomcat/bin/shutdown.sh
sh /usr/local/tomcat/bin/startup.sh
;;
esac
exit 0
You'll need to make the script executable by running the chmod command:

sudo chmod 755 /etc/init.d/tomcat

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/tomcat /etc/rc1.d/K99tomcat

sudo ln -s /etc/init.d/tomcat /etc/rc2.d/S99tomcat
