Install Tomcat 6 on linux step by step

Download and Install JAVA

Download j2sdk-1.4.2 from Sun Download center Sun Developer Network (SDN) Downloads Here I have used j2sdk-1_4_2_18-linux-i586-rpm.bin which will install j2sdk using RPMS and set the Path of JAVA_HOME automatically

Quote:

#chmod +x j2sdk-1_4_2_09-linux-i586.bin #./j2sdk-1_4_2_09-linux-i586.bin

Now Check if Java is installed on the server using command java -version

Quote:

[root@vps907 ~]# java -version java version "1.6.0_07" Java(TM) SE Runtime Environment (build 1.6.0_07-b06) Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

Download Tomcat

Quote:

#cd /usr/local/ #wget Blue Dog Fan Blogs #tar -zxvf apache-tomcat-6.0.18.tar.gz

Create Symlink for the Tomcat Folder

Quote:

#ln -s /usr/local/apache-tomcat-6.0.18 /usr/local/apache/tomcat

Install Tomcat

Quote:

#cd apache-tomcat-6.0.18 #cd bin #tar xvfz jsvc.tar.gz #cd jsvc-src #chmod +x configure #./configure #make #cp jsvc .. #cd ..

Start Tomcat

Use Following script to start Tomcat Service on the Server

Quote:

#/usr/local/apache/tomcat/bin/startup.sh

Running Tomcat as non root user

Due to security reasons always run tomcat as non-root user i.e. tomcat. Following are the steps to run tomcat as non-root user

Quote:

#chown tomcat.tomcat /usr/local/apache-tomcat-6.0.18 -R

Now Tomcat can be stopped and started under user tomcat using following commands:

Quote:

#su -l tomcat -c /usr/local/apache/tomcat/bin/startup.sh #su -l tomcat -c /usr/local/apache/tomcat/bin/shutdown.sh

Test Tomcat installation
open a browser and browse website http://xx.xx.xx.xx:8080 where xx.xx.xx.xx will be your Server IP and If you get following output than Tomcat has been installed properly on the Server.



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

Quote:

#chown 755 /etc/init.d/tomcat

Add and Enable tomcat for all the Run-levels

Quote:

#chkconfig --add tomcat #chkconfig tomcat on

Now you can restart tomcat service using following commands (you can check the screenshot too)

#service tomcat restart <<< To restart tomcat
#service tomcat stop <<< To stop Tomcat
#service tomcat start <<< To start Tomcat
#service tomcat Status <<< to check the status of Tomcat
