Please do the following to make apache as independent server :
1. In your jboss master's domain.xml replace <subsystem xmlns="urn:jboss:domain:modcluster:1.0">
</subsystem> with the following :
<mod-cluster-config advertise-socket="modcluster" proxy-list="10.10.0.1:port">
this will tell the master that it has to get registered to apache located at the following address:port.
Similarly all the slave host use the Master domain.xml, so they will also get registered to the mod cluster service.
