    Configuration of Apache 2.4 mod_cluster for JBoss EAP 6.4 Domain

    Gian Carlos Barros Honório Newbie

      Hello, I have an application that runs with JBoss EAP 6.4 in domain mode, and I'm trying to configure an Apache with module mod_cluster to do the load balancing, however I'm having some difficulty setting up the proxy. Below are the settings that I tried to use:

       

      <subsystem xmlns="urn:jboss:domain:modcluster:1.2">

           <mod-cluster-config advertise-socket="modcluster" proxy-list="192.168.8.91:6666" balancer="myCluster" sticky-session="true" sticky-session-force="false" connector="ajp">

                <dynamic-load-provider>

                     <load-metric type="busyness"/>

                </dynamic-load-provider>

           </mod-cluster-config>

      </subsystem>

       

      <IfModule manager_module>

           Listen 6666

           ManagerBalancerName myCluster

       

           <VirtualHost *:6666>

                <Location />

                     Require all granted

                </Location>

                KeepAliveTimeout 5

                MaxKeepAliveRequests 0

                AdvertiseFrequency 30

                EnableMCPMReceive on

                <Location /modcluster_manager>

                     SetHandler mod_cluster-manager

                     Order deny,allow

                     Allow from 192.168.0.0/23

                     Require all granted

                </Location>

           </VirtualHost>

           <VirtualHost *:80>

                ProxyPreserveHost On

                ProxyPass /server-status !

                ProxyPass / http://192.168.8.91:6666/app/

                ProxyPassReverse / http://192.168.8.91:6666/app/

                ProxyPassReverseCookiePath / /

                <Location /server-status>

                     SetHandler server-status

                     Order deny,allow

                     Deny from all

                     Allow from 192.168.0.0/23

                </Location>

           </VirtualHost>

      </IfModule>

       

      With these settings I was able to get the desired result, but I noticed that with each request made by a client, the Apache server creates one more, I imagine that because of how the proxy was configured, which makes the application performance severely impaired. So I tried different setup:

       

      <IfModule manager_module>

           Listen 6666

           ManagerBalancerName myCluster

       

           KeepAliveTimeout 5

           MaxKeepAliveRequests 0

           AdvertiseFrequency 30

       

           RewriteEngine on

       

           RewriteRule "^/$" "/app/" [R,L]

       

           <Location /server-status>

                SetHandler server-status

                Order deny,allow

                Deny from all

                Allow from 192.168.0.0/23

           </Location>

       

           <VirtualHost *:6666>

                EnableMCPMReceive on

                <Location />

                     Require all granted

                </Location>

                <Location /modcluster_manager>

                     SetHandler mod_cluster-manager

                     Order deny,allow

                     Allow from 192.168.0.0/23

                     Require all granted

                </Location>

           </VirtualHost>

      </IfModule>

       

      Using this second configuration I noticed that the performance improves a lot and the requests are not duplicated, however I was not able to remove the "/app" from the url, because I believe it is only possible to do this using the proxy.

       

      What I want to do is: Any request that Apache receives on port 80 it should redirect to the Jboss load balancer. What is the bestt, most efficient and most correct way to do this?
