Apache, Java, Software | How to setup Apache Tomcat, Java on CentOS?

Below set of steps involve setting up Tomcat 6 on CentOS 5 with Java 1.6

Download Apache Tomcat

$ wget http://apache.parentingamerica.com/tomcat/tomcat-6/v6.0.36/bin/apache-tomcat-6.0.36.tar.gz

Go to opt/ folder and extract Tomcat

$ cd /opt

$ tar -xzf apache-tomcat-6.0.36.tar.gz

Create a tomcat user

$ useradd -d /opt/apache-tomcat-6.0.36/ tomcatuser

Change user permission on tomcat folder

$ chown -R tomcatuser:tomcatuser apache-tomcat-6.0.36

$ vi /etc/init.d/tomcat

#!/bin/bash
#
# tomcat       Starts Tomcat Java server.
#
#
# chkconfig: 345 88 12
# description: Tomcat is the server for 
# Java servlet applications.
### BEGIN INIT INFO
# Provides: $tomcat
### END INIT INFO
 

JAVA_HOME=/usr/java/jdk1.6.0_37
export JAVA_HOME  
PATH=$JAVA_HOME/bin:$PATH  
export PATH  

TOMCAT_HOME=/opt/apache-tomcat-6.0.36/bin
START_TOMCAT=/opt/apache-tomcat-6.0.36/bin/startup.sh
STOP_TOMCAT=/opt/apache-tomcat-6.0.36/bin/shutdown.sh
 
# Source function library.
. /etc/init.d/functions
 
[ -f $START_TOMCAT ] || exit 0
[ -f $STOP_TOMCAT ] || exit 0
 
RETVAL=0
 
umask 077
 
start() {
        echo -n $"Starting Tomcat Java server: "
        daemon su -c $START_TOMCAT tomcatuser
        echo
        return $RETVAL
}
stop() {
        echo -n $"Shutting down Tomcat Java server: "
        daemon su -c $STOP_TOMCAT tomcatuser
        echo
        return $RETVAL
}
restart() {
        stop
        start
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart|reload)
        restart
        ;;
  *)
        echo $"Usage: $0 {start|stop|restart}"
        exit 1
esac
 
exit $?

Now save the file

Give executable rights for that script

$ chmod 755 /etc/init.d/tomcat

Add the script to CentOS services

$ chkconfig –add tomcat

Check the changes

$ chkconfig –level 234 tomcat on

$ chkconfig –list tomcat

tomcat 0:off 1:off 2:on 3:on 4:on 5:on 6:off

Test that the script is working and it gives no errors

$ service tomcat start
$ service tomcat restart
$ service tomcat stop
