Creating Service for starting/stopping Tomcat Unix

Create the init script in /etc/init.d/tomcat7 with the contents as per below (your script should work too but I think this one adheres more closely to the standards).

This way Tomcat will start only after network interfaces have been configured.

Init script contents:

#!/bin/bash

### BEGIN INIT INFO
# Provides:        tomcat7
# Required-Start:  $network
# Required-Stop:   $network
# Default-Start:   2 3 4 5
# Default-Stop:    0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO

PATH=/sbin:/bin:/usr/sbin:/usr/bin

start() {
 sh /usr/share/tomcat7/bin/startup.sh
}

stop() {
 sh /usr/share/tomcat7/bin/shutdown.sh
}

case $1 in
  start|stop) $1;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac

Change its permissions and add the correct symlinks automatically:

chmod 755 /etc/init.d/tomcat7
update-rc.d tomcat7 defaults

And from now on it will be automatically started and shut down upon entering the appropriate runlevels. You can also control it with service tomcat7 <stop|start|restart>
