Step 2: Download Tomcat 7 Archive

After configuring JAVA properly on your system, let’s download Apache tomcat archive file from Apache official site using http://tomcat.apache.org/download-70.cgi or use the following command to download Tomcat 7.0.68 from Apache server.

$ cd /opt
$ wget http://www.us.apache.org/dist/tomcat/tomcat-7/v7.0.75/bin/apache-tomcat-7.0.75.tar.gz

After competed download extract archive file in /opt directory. You may change this location as per your setup.

$ tar xzf apache-tomcat-7.0.75.tar.gz
$ mv apache-tomcat-7.0.75 tomcat7

Download Binary Distributions.

Step 3: Setup Environment Variable

Before starting Tomcat, Configure environment variables by adding an entry in the ~/.bashrc file, So that system environment can set on system bootup with the following command.

$ echo "export CATALINA_HOME="/opt/tomcat7"" >> ~/.bashrc
$ source ~/.bashrc

Or you can config on /etc/enviroment

Step 4: Start Tomcat

After completing all above configuration, Let’s use below command to start Tomcat. There are no need to compile its source. Tomcat by default start on port 8080, So make sure no other application using the same port.

$ cd /opt/tomcat7
$ ./bin/startup.sh

Step 5: Access Tomcat

Tomcat server works on port 8080 default. Access tomcat on a web browser by connecting your server on port 8080.

#!/bin/bash

### BEGIN INIT INFO
# Provides:        tomcat7
# Required-Start:  $network
# Required-Stop:   $network
# Default-Start:   2 3 4 5
# Default-Stop:    0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO

PATH=/sbin:/bin:/usr/sbin:/usr/bin

start() {
 sh /opt/tomcat7/bin/startup.sh
}

stop() {
 sh /opt/tomcat7/bin/shutdown.sh
}

case $1 in
  start) start;;
  stop)  stop;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac

Now execute following commands to set proper permissions and symbolic links for init script.
