Pre-requisites

JDK (java) should be install.
1. To Install Java

Download tarball package.

Goto the downloaded directory. Extract tarball jdk-6u31-linux-x64.tar.gz

	sudo tar-xzf jdk-6u31-linux-x64.tar.gz -C /opt
	Set Environment variable

vim /etc/profile
.
.
.
	JAVA_HOME=<path-to-jdk-extracted-directory>
	export JAVA_HOME
	PATH=$JAVA_HOME:$PATH
:wq!

2. Configure tomcat

Download Tomcat binary distribution from http://tomcat.apache.org/download-70.cgi, then extract it

	tar -zxf <path-to-tomcat-tarball> -C /opt/
	Start tomcat server

cd /opt/<tomcat-dir>/bin
./startup.sh
Open http://localhost:8080, 8080 is default for tomcat

3. Create virtualhost in tomcat

Goto the tomcat root directory

	cd /opt/<tomcat-root-directory>
vim conf/server.xml
.
.
<Engine....>
 <Host name="localhost"  appBase="webapps" aunpackWARs="true" autoDeploy="true">
.
.
.    
</Host>
<!-- Custom Virtual host -->
<Host name="abc.example.com" appBase="sample" unpackWARs   ="true" autoDeploy="true">
    <Context path="" docBase="/opt/apache-tomcat-7.0.40/sample.war"/>
</Host>
</Engine>
:wq!
Restart Apache tomcat server

	cd /opt/<tomcat-dir>/bin
	./shutdown.sh
	./startup.sh
now open url http://abc.example.com:8080

Integrate tomcat with apache

Install apache-jk module
	sudo apt-get install libapache2-mod-jk
Now create our /etc/apache2/workers.properties file for Apache
# Define 1 real worker using ajp13 
	worker.list=worker1 
# Set properties for worker (ajp13) 
	worker.worker1.type=ajp13 
	worker.worker1.host=localhost
	worker.worker1.port=8009
Now set workers file to jk module in  Apache.
vim /etc/apache2/mods-available/jk.conf
    	JkWorkersFile /etc/apache2/mods-available/jk.conf
:wq!
Now create virtual host
vim /etc/apache2/sites-available/example.com.conf
	<virtualhost *:80>
	servername abc.example.com
	documentroot /opt/apache-tomcat-7.0.40/sample.war
	jkmount /* worker1
	</virtualhost>
Enable virtualhost
	sudo ln -s /etc/apache2/sites-available/dbc.example.com.conf /etc/apache2/sites-enable/.
	Restart apache server

sudo /etc/init.d/apache2 restart
