Manual Installation of Tomcat from Zip file on Ubuntu 12.04:

You can use this guide to manually install the glassfish on Ubuntu 12.04 Server

1)      Visit http://tomcat.apache.org/ to download the latest tomcat installer

2)      Unzip it with tar -zxvf Tomcatxxx.tar

                          tar -zxvf apache-tomcat-6.0.16.tar.gz

3)      Move the folder contents to the required directory. In my case, it is /app/tomcat directory

4)      Now create an user tomcat to run the tomcat service under this username. Also change the directory permissions to tomcat

#useradd tomcat

Or

#adduser tomcat

#chown -R tomcat:tomcat /app/tomcat/

#chmod 775 -R /app/tomcat

5)      Check whether java is already installed by sung this command

#java –version

If it is not installed, then refer this post to install JDK or refer this post to install JRE

6)      Create a file called tomcat in the following path /etc/init.d/ to create tomcat service file. It should have the following lines in it

export CATALINA_HOME=”/app/tomcat” case “$1″ in start) tomcat_id=$(ps -ef | grep $CATALINA_HOME | grep -v grep | awk ‘{print $2}’ | head -n 1) if [ -n "$tomcat_id" ] then echo “Tomcat is already Running with PID:” $tomcat_id else echo “Starting tomcat from $CATALINA_HOME” sudo -u tomcat authbind –deep $CATALINA_HOME/bin/startup.sh fi ;; stop) tomcat_id=$(ps -ef | grep $CATALINA_HOME | grep -v grep | awk ‘{print $2}’ | head -n 1) if [ -n "$tomcat_id" ] then echo “Stopping tomcat from $CATALINA_HOME” sudo -u tomcat authbind –deep $CATALINA_HOME/bin/shutdown.sh else echo “Tomcat is not running” fi ;; status) tomcat_id=$(ps -ef | grep $CATALINA_HOME | grep -v grep | awk ‘{print $2}’ | head -n 1) if [ -n "$tomcat_id" ] then echo “Tomcat is Running with PID:” $tomcat_id else echo “Tomcat is not Running…….” fi ;; *) echo $”usage: $0 {start|stop|status}” exit 3 ;; esac

Note:
Install authbind if required by typing apt-get install authbind

7)      Finally apply 0755 permissions to tomcat file

#chown -R tomcat:tomcat /etc/init.d/tomcat  #chmod 775 /etc/init.d/tomcat

8)      Now you can start the tomcat using any of the following commands

# sh /app/tomcat/bin/startup.sh  # /etc/init.d/tomcat start

9)      To link the service in desired run levels in ubuntu server, install the following utility

#apt-get install sysv-rc-conf

10)   Then open the utility and enable the service in all run levels as shown in the screenshot

# sysv-rc-conf

11)   Done, tomcat is ready for use.
