How to configure two apache tomcat instances in the same machine both Windows and Linux ?

Introduction:

In this article, we will explore How to configure two apache tomcat instances in the same machine  both Windows and Linux? 

Configuring Tomcat port

By default tomcat binding ports are 8005, 8080 and 8009.

If you have another tomcat instance running on same server or other application like JBoss Application Server, these ports are likely already used. In this case you should change the default ports.

Change tomcat ports

The port change must be done with the tomcat application stopped.

Edit $TOMCAT_Home/config/server.xml and check all Tomcat port properties.

Shut-down Port	8005	8105
	Change <Server port="8005" shutdown="SHUTDOWN"> to <Server port="8105" shutdown="SHUTDOWN">

Tomcat Connector Port	8080	8180
	Change <Connector address="0.0.0.0" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> to <Connector address="0.0.0.0" connectionTimeout="20000" port="8180" protocol="HTTP/1.1" redirectPort="8443"/>

AJP Connector Port	8009	8109
	Change <Connector address="127.0.0.1" port="8009" protocol="AJP/1.3" redirectPort="8443"/> to <Connector address="127.0.0.1" port="8109" protocol="AJP/1.3" redirectPort="8443"/>

To shut-down the different instances execute the shutdown.sh script from each $TOMCAT_HOME/bin.
