Jboss Eap-mod_cluster-防止jboss互相交谈

Question

I have a jboss setup with 2 jboss instances on one VM. Each of the 2 jboss talk to 2 apaches on same VM.

Apache 1 apache listen port is 82

<VirtualHost 192.168.1.2:6262>

    <Directory />
        Order deny,allow
        Allow from all
    </Directory>

  KeepAliveTimeout 60
  MaxKeepAliveRequests 0

  ManagerBalancerName box1_cluster
  ServerAdvertise Off
# AdvertiseFrequency 5
  EnableMCPMReceive On

  <Location /mod_cluster-manager>
    SetHandler mod_cluster-manager
    Order deny,allow
    Allow from all
  </Location>
</VirtualHost>

jboss 1

        <subsystem xmlns="urn:jboss:domain:modcluster:1.1">
          <mod-cluster-config advertise-socket="modcluster" connector="ajp" proxy-list="192.168.1.2:6262" balancer="box1_cluster">

  <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">


        <socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="23364"/>

    <Directory />
        Order deny,allow
        Allow from all
    </Directory>

  KeepAliveTimeout 60

jboss 2

     <subsystem xmlns="urn:jboss:domain:modcluster:1.1">
          <mod-cluster-config advertise-socket="modcluster" connector="ajp" proxy-list="192.168.1.2:6263" balancer="box2_cluster">
            <dynamic-load-provider>
              <load-metric type="busyness"/>
            </dynamic-load-provider>
          </mod-cluster-config>
        </subsystem>

  <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">

        <socket-binding name="txn-status-manager" port="4713"/>
        <socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="23364"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>

The apache works well and connect to jboss .The apache also detects all deployed apps.

Questions:-

When the

192.168.1.2:6262/mod_cluster-manager is done it shows the applications deployed on the 2nd jboss. I want to make sure that the apache 1 detects application that are deployed in jboss 1 and no other applications. Basically i want to use mod_cluster but dont want one jboss to talk to another.I want to use mod_cluster for jboss to autopublish applications to apache.But i dont want 2 jboss to talk to each other.

Answer 1

If you do not want two JBoss instances cross talk (since they are not in the same cluster) then you should have the 2 nodes listen on unique multicast addresses.

By the way, if you do not use clustering you are losing the ability of session replication and high availability.
