Apache2.2 Tomcat6 Cluster Configuration for Windows

 

1,add following lines in httpd

 

 

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties

JkMountFile conf/uriworkermap.properties

JkLogFile logs/mod_jk.log

JkLogLevel warn

JkMount /* controller   

 

 

2,download mod_jk.so,and copy into folder modules

3,create workers.properties,and content is the followng:

 

worker.list=controller

worker.tomcat1.host=192.168.3.2

worker.tomcat1.port=8009

worker.tomcat1.type=ajp13

worker.tomcat1.connect_timeout=10000

worker.tomcat1.lbfactor = 6 

 

worker.tomcat2.host=192.168.3.2

worker.tomcat2.port=9009

worker.tomcat2.type=ajp13

worker.tomcat2.connect_timeout=10000

worker.tomcat2.lbfactor = 2 

 

worker.tomcat3.host=192.168.3.2

worker.tomcat3.port=9010

worker.tomcat3.type=ajp13

worker.tomcat3.connect_timeout=10000

worker.tomcat3.lbfactor = 2 

 

worker.tomcat4.host=192.168.3.3

worker.tomcat4.port=8009

worker.tomcat4.type=ajp13

worker.tomcat4.connect_timeout=15000

worker.tomcat4.lbfactor = 2 

 

worker.controller.type=lb

worker.controller.balance_workers=tomcat1,tomcat2,tomcat3,tomcat4

worker.controller.sticky_session=True

 

4,create uriworkermap.properties,and content is:

 

/*=controller

 

 

5,config server.xml in folder tomcat/conf

 

 1)<Engine name="Catalina" defaultHost="localhost" >   ----> <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

2)add the following code

 

<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"/>     

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

                    address="auto"  

                   port="4001"    

                   autoBind="100"    

                   selectorTimeout="5000"    

                   maxThreads="6"/>     

         <!-- timeout="60000"-->     

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

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

         </Sender>     

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

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

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

       </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>  

 

Note:port="4001" ,the port should be modidfied in diffrent tomcat

 

3)modify the following ports;

 

<Server port="8005" shutdown="SHUTDOWN">

<Connector port="8401" protocol="HTTP/1.1" 

               connectionTimeout="20000" 

               redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

 

6,note

if you set environment variable CATALINA_HOME,remember to modify the file: startup.bat/sh and catalina.bat.

 

 

add the line in  above files

set CATALINA_HOME=C:\apache-tomcat-cluster2
