Step by step Installing Tomcat 6 on Redhat Enterprise Linux.

 *********************

Tomcat 6 on CentOS 5.2

1. Download jdk-6u11-linux-i586-rpm.bin from

http://java.sun.com/javase/downloads/index.jsp.

2. cd Desktop;

 #./ jdk-6u11-linux-i586.bin

3. As root, insert following lines in /etc/profile.

#vim /etc/profile --add below code..

export JAVA_HOME=/usr/java/default

export PATH=$PATH:$JAVA_HOME/bin

export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

4. . /etc/profile

5. #mkdir /tmp; cd /tmp

6. wget http://ftp.sh.cvut.cz/MIRRORS/apache/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz

7. #tar xvzf apache-tomcat-6.0.18.tar.gz

8. #mv -f apache-tomcat-6.0.18 /usr/share/tomcat6

9. #chown -R tomcat /usr/share/tomcat6

10. #ln -s /usr/share/tomcat6 /usr/share/tomcat

11. #useradd -d /usr/share/tomcat -s /sbin/nologin tomcat

12. Create /etc/init.d/tomcat as shown below:(Script to start, stop and restart Tomcat)
The above installation step will not create tomcat service so that user can restart tomcat using command service tomcat restart. Create a new file in /etc/init.d as tomcat and copy following contenents into it.

Quote:

#vi /etc/init.d/tomcat #!/bin/bash # # Startup script for Tomcat # # chkconfig: 345 84 16 # description: Tomcat jakarta JSP server #Necessary environment variables export CATALINA_HOME="/usr/local/tomcat" if [ ! -f $CATALINA_HOME/bin/catalina.sh ] then echo "Tomcat not available..." exit fi start() { echo -n -e '\E[0;0m'"\033[1;32mStarting Tomcat: \033[0m \n" su -l tomcat -c $CATALINA_HOME/bin/startup.sh echo touch /var/lock/subsys/tomcatd sleep 3 } stop() { echo -n -e '\E[0;0m'"\033[1;31mShutting down Tomcat: \033[m \n" su -l tomcat -c $CATALINA_HOME/bin/shutdown.sh rm -f /var/lock/subsys/tomcatd echo } status() { ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap start" | awk '{printf $1 " "}' | wc | awk '{print $2}' > /tmp/tomcat_process_count.txt read line < /tmp/tomcat_process_count.txt if [ $line -gt 0 ]; then echo -n "tomcatd ( pid " ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap start" | awk '{printf $1 " "}' echo -n ") is running..." echo else echo "Tomcat is stopped" fi } case "$1" in start) start ;; stop) stop ;; restart) stop sleep 3 start ;; status) status ;; *) echo "Usage: tomcatd {start|stop|restart|status}" exit 1 esac

Save and exit from the file. Now assign executable permission to this file

#vim /etc/init.d/tomcat---add below code...

# Tomcat auto-start

#

# description: Auto-starts tomcat

# processname: tomcat

# pidfile: /var/run/tomcat.pid

export JAVA_HOME=/usr/java/default

case $1 in

start)

sh /usr/share/tomcat6/bin/startup.sh

;;

stop)

sh /usr/share/tomcat6/bin/shutdown.sh

;;

restart)

sh /usr/share/tomcat6/bin/shutdown.sh

sh /usr/share/tomcat6/bin/startup.sh

;;

esac

exit 0

:wq

13. #chmod +x /etc/init.d/tomcat

14. #chkconfig tomcat6 on

15. Add following into /usr/share/tomcat/conf/tomcat-users.xml:

#vim /usr/share/tomcat/conf/tomcat-users.xml

 <user username="tomcat" password="tomcat" roles="manager,admin">

16. Add $CATALINA_HOME to /etc/profile.

#vim /etc/profile

export CATALINA_HOME=/usr/share/tomcat

17. #/etc/init.d/tomcat start

18. If the Apache Tomcat page can be found at http://localhost:8080, the installation is correct.

-->open browser--->http://localhost:8080

19. Done.
