worker.tomcat3.port=8012

worker.tomcat3.lbfactor=10

worker.balancer.type=lb

worker.balancer.balance_workers=tomcat1,tomcat2,tomcat3

worker.stat.type=status

Download Tomcat Mod_Jk connector from below link and past it into apache Module directory.

http://apache.osuosl.org/tomcat/tomcat-connectors/jk/binaries/windows/

Restart Apache….

Tomcat Cluster Configuration….

Download tomcat from below link.

http://tomcat.apache.org/download-70.cgi

Create directory for tomcat cluster instances called “T_Cluster”.

Under directory “T_Cluster” create three directories for three tomcat instances and extract downloaded tomcat into each instance directory.

Edit Server.xml file for instance configuration make below changes in file.

1.       Change Default shutdown Port.  

<Server port="8007" shutdown="SHUTDOWN">

2.       Change Default AJP Port.

<Connector port="8011" protocol="AJP/1.3" redirectPort="8443" />

3.       Add JvmRoute name.

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

4.       Cluster Configuration make sure you add below lines below cluster configuration will be same for other instances.

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="8">

                <Manager            className="org.apache.catalina.ha.session.DeltaManager"

                                                                expireSessionsOnShutdown="false"

                                                                notifyListenersOnReplication="true"/>

               

                <Channel className="org.apache.catalina.tribes.group.GroupChannel">

                                <Membership className="org.apache.catalina.tribes.membership.McastService"

                                                                                address="228.0.0.4"

                                                                                port="45564"

                                                                                frequency="500"

                                                                                dropTime="3000"/>

                               

<Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">

                                                <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>

                                </Sender>

                                               

                                <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"

                                                                                address="auto"

                                                                                port="4001"

                                                                                autoBind="100"

                                                                                selectorTimeout="5000"

                                                                                maxThreads="6"/>

                                                                               

                                <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>

                               

                                <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>

                               

                </Channel>

               

                <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>

               

                <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

               

                <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

               

                <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

               

</Cluster>

Cluster Configuration End’s here.

Make above changes in other two instances.

In the deployed application add “<distributable/>” Tag in web.xml file for session replication.

Now open CMD and start tomcat.

C:\>cd T_Cluster\Node-1\bin

C:\T_Cluster\Node-1\bin>startup.bat

Start all three tomcat instances.

Restart Apache server…

Testing…

Access apache server URL with configured port.

http://127.0.0.1:8080

Check tomcat individual URL’s.

http://127.0.0.1:8181

http://127.0.0.1:8282

http://127.0.0.1:8282
