    Mod_Cluster /context root mapping issue in JBOSS EAP 6.2  with  httpd Apache Webserver

    sridhar a.r Newbie

      Hi Friends,

       

       

      1) I have two Jboss EAP 6.2 domain ( say Domain A & Domain B) working in cluster mode.

       

      Domain A : Architecture is as below

      Host X Host Y

      Node 1 Node2

       

      An Application with context root "/checkin" is deployed in this Domain A

       

       

      Domain B : Architecture is as below

      Host X Host Y

      Node 3 Node4

       

       

      An Application with context root "/checkout" is deployed in this Domain  B

       

       

      2) I have used two httpd apache  webserver ( say  integration.com  & acceptance.com ) :

       

       

      Application with content root /checkin is  hosted via  mod_cluster configurartion  in  integration.com  ( www.integation.com/checkin )

       

      Application with content root /checkout is hosted via  mod_cluster configurartion  in  acceptance.com   ( www.acceptance.com/checkout )

       

       

      3)My integation Webserver Configuration is as below:

        +++++++++++++++++++++++++++++++++++++++++

       

       

      Listen 10.9.8.27:8777

       

      <VirtualHost 10.9.8.27:80>

      <Directory />

      Order Allow,Deny

      Allow from all

      </Directory>

      <Location /mc>

      SetHandler mod_cluster-manager

      Order Allow,Deny

      Allow from all

      </Location>

      </VirtualHost>

       

       

      <VirtualHost 10.9.8.27:8777>

      <Directory />

      Order Allow,Deny

      Allow from all

      </Directory>

      ServerAdvertise on http://10.9.8.27:8777

      AdvertiseGroup 224.0.1.105:8662

      </VirtualHost>

       

       

      8777 - Virtual port used in Webserver

      8662 - Multicast port used in domain.xml of domain A

       

       

      Entry in domain.xml of domain A

      <socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="8662"/>

       

       

      4)My Acceptance Webserver Configuration is as below:

        +++++++++++++++++++++++++++++++++++++++++

       

       

      Listen 10.9.8.23:7777

       

      <VirtualHost 10.9.8.23:80>

      <Directory />

      Order Allow,Deny

      Allow from all

      </Directory>

      <Location /mc>

      SetHandler mod_cluster-manager

      Order Allow,Deny

      Allow from all

      </Location>

      </VirtualHost>

       

       

      <VirtualHost 10.9.8.23:7777>

      <Directory />

      Order Allow,Deny

      Allow from all

      </Directory>

      ServerAdvertise on http://10.9.8.23:7777

      AdvertiseGroup 224.0.1.105:8682

      </VirtualHost>

       

       

      7777 - Virtual port used in Webserver

      8682 - Multicast port used in domain.xml of domain B

       

      Entry in domain.xml of domain B :

      <socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="8682"/>

       

       

      5) My Mod_cluster  management console output for integraton Webserver  is as follows:

      Context: [4:1:4], Context: /checkout, Status: ENABLED

       

       

      7) Issue statement :

       

      All 4 Nodes are visible to  both the webservers  ( integration & acceptance) so  content root  /checkin & /checkout  are accessible from both the webservers but

      I need  /checkin to be accessible only  from  www.integration.com and   /checkout to be accessible only from www.acceptance.com

       

      i.e.

      I need only Node1 and Node2 to  Listen to proxy advertisements on  224.0.1.105:8662

      &

      I need only Node3 and Node4 to  Listen to proxy advertisements on  224.0.1.105:8682

       

       

      Kindly let me know how I can instruct the worker nodes(Node 1 & Node2) to join only a specified  <multicast_addr:port> and  also instruct  worker nodes(Node 3 & Node 4) to join <some_other_multicast_addr:some_other_port>

       

       

      Thanks in Advance
