    Apache loadbalancer and XmlRpc Server

    André Simões Newbie

      Hi there.

       

      I have a JBOSS 5.10 running in cluster.

      Two instances on the same physical machine.

       

      I also have a xmlrpc server running on port 8081 of each cluster node.
      The server is working fine.


      But, when i try to access them from the apache ip, the load balancer sends data to the cluster but it return a bad answer

       

      I'm reading the apache log and from the log i can have sure that data is arriving on the cluster ip and port

       

      Does the Xml Rpc Server or the load balancer need some extra options to work in cluster?

          One more thing.

          If I try a wget from another machine, the answer is:

           

           

          For Apache Ip and port that forwards for xmlrpcserver:

           

          wget -S 10.1.4.200:8082
          --2010-10-13 09:58:35--  http://10.1.4.200:8082/
          Connecting to 10.1.4.200:8082... connected.
          HTTP request sent, awaiting response...
            HTTP/1.1 200 OK
            Date: Wed, 13 Oct 2010 08:58:42 GMT

          Length: 1748 (1,7K) [text/html]

           

           

          For a specific node Ip:

           

          wget -S 192.168.0.21:8081
          --2010-10-13 09:46:58--  http://192.168.0.21:8081/
          Connecting to 192.168.0.21:8081... connected.
          HTTP request sent, awaiting response... No data received.
          Retrying.

           

          The second example produces a message on jboss node. That message is the expected one.

           

           

          I think my problem is what to put on VirtualHost of apache.

          In JkMount i have:

          For general purpose:

          <VirtualHost *:80>
              ServerName 10.1.4.200
          #    LogLevel warn
              JkLogLevel debug
              CustomLog logs/vtHt80.log combined
              ErrorLog logs/vtHt80Error.log
          #    ServerSignature Off
              ServerSignature On
             
          #    JkAutoAlias /
              JkMountFile conf/uriworkermap.properties
          </VirtualHost>

           

          For XmlRpcServer

          <VirtualHost *:8082>
              ServerName 10.1.4.200
              ServerSignature Off
          #    LogLevel warn
              JkLogLevel debug
              CustomLog logs/vtHt8081.log combined
              ErrorLog logs/vtHt8081Error.log
              ServerSignature Off
             
          #    JkAutoAlias /
              JkMount /* workerXmlRpc
          </VirtualHost>

           

          The big question is:

          Does the VirtualHost 8082 have a correct JkMount?

           

          I think that the problem is there, but i can't fix it

            I found the solution.

            Use mod_proxy for redirect traffic to clusters.

            AJP connector won't work
