    Wildfly 8, mod_cluster & apache integration

    M P Newbie

      I am having problems getting mod_cluster 1.2 to work with Apache.

       

      Symptoms:

      When I start Wildfly the console produces the following error every 3-5 seconds:

      ERROR [org.jboss.modcluster] (UndertowEventHandlerAdapter - 1) MODCLUSTER000042: Error null sending INFO command to precise32/127.0.1.1:6666, configuration will be reset: null

       

      I can see a corresponding request in my Apache logs as: "INFO / HTTP/1.1" 501 529 "-" "ClusterListener/1.0"

       

      The http://localhost:9191/mod_cluster-manager URL only shows the page title and links, but no cluster info:

      mod_cluster/1.2.6.Final

      Auto Refresh show DUMP output show INFO output

       

      I am running both jboss and apache on the same virtual server.

      Server Info:

      Virtual Box 4.3.14 running:

      Ubuntu 12.04 LTS

      Apache/2.2.22

      Wildfly 8.0

       

      I can navigate to my web apps on Wildfly directly without going through Apache and it works fine. If I try and navigate through Apache, I get the following errors in my Apache log:

      [Thu Oct 16 03:12:33 2014] [debug] mod_proxy_cluster.c(2231): proxy: byrequests balancer FAILED

      [Thu Oct 16 03:12:33 2014] [error] proxy: CLUSTER: (balancer://mycluster). All workers are in error state

      My relevant Apache configs look like:
