    proxy_cluster_isup: Can't find worker for 1

    Claudio Miranda Expert

      Hi, see my system

       

      - Fedora Linux 12

      - httpd -v Server version: Apache/2.2.15 (yum install)

      - mod_cluster httpd modules: mod_cluster-1.0.4.GA-linux2-x86-so.tar.gz

      - JBoss EAP 5.1.0

      - mod_cluster.sar copied from EAP/mod_cluster/mod_cluster.sar

       

      I cannot use a recent mod_cluster version, because EAP already support 1.0.4

       

      $ cat /etc/httpd/conf.d/jboss_cluster.conf

      #  by claudio

      LoadModule slotmem_module modules/mod_slotmem.so

      LoadModule manager_module modules/mod_manager.so

      LoadModule proxy_cluster_module modules/mod_proxy_cluster.so

      LoadModule advertise_module modules/mod_advertise.so

      ===> When the httpd is started it prints

       

      [Wed Feb 23 12:28:10 2011] [debug] mod_manager.c(1432): manager_trans ENABLE-APP (/)

      [Wed Feb 23 12:28:10 2011] [debug] mod_manager.c(1988): manager_handler ENABLE-APP  OK

       

       

      ===> Going to /cluster-manager it shows

      Auto Refresh show DUMP output show INFO output

      Node lb-1 (ajp://192.168.1.10:8009):

      Enable Contexts Disable Contexts

      Balancer: mycluster,Domain: ,Flushpackets: Off,Flushwait: 10000,Ping: 10000000,Smax: 1,Ttl: 60000000,Elected: 0,Read: 0,Transferred: 0,Connected: 0,Load: 0

      Virtual Host 1:

      Contexts:

      /jmx-console, Status: ENABLED Disable
      /load-demo, Status: ENABLED Disable

      Aliases:

      localhost

       

      So, looks like everything is fine.

       

      ===> So I type into the browser http://<machine>/load-demo/sessions

       

      Not Found

      The requested URL /load-demo/sessions was not found on this server.

      Going directly to jboss, it works

       

      http://<machine>:8080/load-demo/sessions

       

      Handled By: lb-1

       

      So, is there anything else I must configure to make this work ?

       

      Thanks
