    Issue with mod_cluster in CentOS

    valsaraj viswanathan Master



      I have added mod_cluster modules to already installed HTTPD 2.4.4 on CentOS 6. After fixing some bugs I am able to access mod_cluster_manager but it is showing Status: NOTOK.


      Versions are:



      HTTPD 2.4.4

      CentOS 6


      Here is the errors noticed in the logs:

      HTTPD log:

      (111)Connection refused: AH00957: ajp: attempt to connect to ( failed

      [proxy:error] [pid 57358:tid 140549438826240] AH00959: ap_proxy_connect_backend disabling worker for ( for 60s

      [proxy:error] [pid 57358:tid 140549581551360] AH00940: ajp: disabled connection for (
