Steps for creating automatic startup/shutdown scripts for Tomcat in Amazon EC2

After Tomcat is installed in EC2, it's time to create a startup/shutdown service script. Below are steps:

1. login to EC2 instance with putty
2. sudo su
3. cd /etc/init.d
4. vim tomcat
5. put following into the file  
#!/bin/bash
# chkconfig: 234 20 80
# description: Tomcat Server basic start/shutdown script
# processname: tomcat
JAVA_HOME=/usr/java/jdk1.6.0_24
export JAVA_HOME
TOMCAT_HOME=/usr/share/apache-tomcat-7.0.23/bin
START_TOMCAT=/usr/share/apache-tomcat-7.0.23/bin/startup.sh
STOP_TOMCAT=/usr/share/apache-tomcat-7.0.23/bin/shutdown.sh
start() { echo -n "Starting tomcat: "
cd $TOMCAT_HOME
${START_TOMCAT}
echo "done." }
stop() { echo -n "Shutting down tomcat: "
cd $TOMCAT_HOME
${STOP_TOMCAT} echo "done." }
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 10
start
;;
*)
echo "Usage: $0 {start|stop|restart}"
esac
exit 0
6. Change permissions.  chmod 755 tomcat
7. Add script to system services. chkconfig --add tomcat
8. Test it out. service tomcat start, service tomcat stop.
