How to automatically restart Tomcat on system reboot time ?

There are 2 method:-

Method 1. Create the init script in /etc/init.d/tomcat with following lines :-

#!/bin/sh
# chkconfig: - 80 20
# Created by: USer
# Purpose: Start or stop the Tomcat service.
# Check the path of Tomcat and set enviorment variables as follows in the .bashrc profile
# chkconfig: 345 99 01
#chkconfig: 2345 50 70
# export CATALINA_HOME="/usr/local/tomcat7/apache-tomcat-7.0.37"
# export CATALINA_BASE="/usr/local/tomcat7/apache-tomcat-7.0.37"
# export JAVA_HOME="/usr/local/java/jdk1.7.0_17"
#export JAVA_HOME="/usr/java/jdk1.5.0_15"
export JAVA_HOME="/usr/java/jdk1.6.0_25"
case $1 in
start)
cd /usr/local/tomcat/bin/
./startup.sh
;;
stop)
cd /usr/local/tomcat/bin/
./shutdown.sh
;;
restart)
cd /usr/local/tomcat/bin/
./shutdown.sh
cd /usr/local/tomcat/bin/
./startup.sh
;;
esac
exit 0

--------------------

Change its permissions and add the correct symlinks automatically:-
chmod 755 /etc/init.d/tomcat7
update-rc.d tomcat7 defaults


Method 2:-
user should be valid "tomcat" and has rw permissions in the $CATALINA_HOME/conf and $CATALINA_HOME/logs directories. and $JAVA_HOME shpuld be proper set. You will start Tomcat as user "tomcat" to avoid running it as root.

Save the following script as /etc/init.d/tomcat . it will automatically be read and run at boot time. Check the log files if it does not start properly.

Make a link to it from /etc/rc5.d such as:

cd /etc/rc5.d
sudo ln -s ../init.d/tomcat S71tomcat

----------------------------  /etc/init.d/tomcat  ------------------------
#!/bin/bash
#
# tomcat      
#
# chkconfig:
# description: Start up the Tomcat servlet engine.

# Source function library.
. /etc/init.d/functions


RETVAL=$?
CATALINA_HOME="/usr/local/tomcat/jakarta-tomcat-6"

case "$1" in
 start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
   echo $"Starting Tomcat"
            /bin/su tomcat $CATALINA_HOME/bin/startup.sh
        fi
;;
 stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
   echo $"Stopping Tomcat"
            /bin/su tomcat $CATALINA_HOME/bin/shutdown.sh
        fi
  ;;
 *)
  echo $"Usage: $0 {start|stop}"
exit 1
;;
esac

exit $RETVAL
-----------------------  end of /etc/init.d/tomcat  ----------------------
