Step 1: Download the following source

   >> apache-tomcat-5.5.30.tar.gz

   >> jdk-6u21-linux-i586.rpm

Step 2: follow the instruction below

   >> adduser tomcat

   >> cd /home/tomcat

Download the source file.

-- wget http://download.filehat.com/apache/tomcat/tomcat-5/v5.5.30/bin/apache-tomcat-5.5.30.tar.gz

-- http://java.sun.com/javase/downloads/index.jsp >> (jdk-6u21-linux-i586.rpm)

   >> chmod a+x jdk-6u21-linux-i586-rpm.bin

   >> ./jdk-6u21-linux-i586-rpm.bin

   >> tar xzvf apache-tomcat-5.5.30.tar.gz

 Edit the file ".bash_profile" and add the following line

   >> vi /home/tomcat/.bash_profile

      add this >> export JAVA_HOME=/usr/java/jdk1.6.0_21

   >> chown tomcat:tomcat apache-tomcat-5.5.30

Step 3: Create starup script for tomcat

   >> vi /etc/init.d/tomcat

   >> chmod 755 /etc/init.d/tomcat

Add the following lines below.........

==========================================================

#!/bin/sh

#

# Startup script for Tomcat

JAVA_HOME=/usr/java/jdk1.6.0_21

export JAVA_HOME

start_tomcat=/home/tomcat/apache-tomcat-5.5.30/bin/startup.sh

stop_tomcat=/home/tomcat/apache-tomcat-5.5.30/bin/shutdown.sh

start() {

        echo -n "Starting tomcat: "

        su -c ${start_tomcat} - tomcat

        echo "done."

}

stop() {

        #echo -n "Shutting down http: "

        echo -n "Shutting down tomcat: "

        ${stop_tomcat}

        echo "done."

}

# See how we were called

case "$1" in

  start)

        start

        ;;

  stop)

        stop

        ;;

  restart)

        stop

        sleep 10

        start

        ;;

  *)

        echo "Usage: $0 {start|stop|restart}"

esac

exit 0

===========================================================

Step 4: Edit /etc/sysconfig/iptables and add the line below

 -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

  >> Restart Iptables 

     > service iptables restart or /etc/init.d/iptables restart

  >> telnet localhost 8080

Example:

    [root@nocdev java]# telnet localhost 8080

    Trying 127.0.0.1...

    Connected to localhost.localdomain (127.0.0.1).

    Escape character is '^]'.

Step 5: Run the tomcat script

    >> /etc/init.d/tomcat start

    You should get this after execute the command.

    [root@nocdev java]# /etc/init.d/tomcat  start

    Starting tomcat: Using CATALINA_BASE:   /home/tomcat/apache-tomcat-5.5.30

    Using CATALINA_HOME:   /home/tomcat/apache-tomcat-5.5.30

    Using CATALINA_TMPDIR: /home/tomcat/apache-tomcat-5.5.30/temp

    Using JRE_HOME:        /usr/java/jdk1.6.0_21

    Using CLASSPATH:       /home/tomcat/apache-tomcat-5.5.30/bin/bootstrap.jar

    done.

Then try to access http://localhost:8080 or http://IP ADDRESS:8080 in your local pc.
