Connecting apache and Widfly using mod_cluster

Question

I am trying to setup mod_cluster as a reverse proxy for Wildfly 9. When I use http as a protocol (between mod_cluster and Wildfly), everything works just fine (forwarding requests to application server and detecting server).

My problems come up when I try to wire mod_cluster and wildfly using ajp as a protocol. I checked mod_cluster-manager and it seemed that mod_cluster was connected to wildfly, but it couldn't forward requests to application server.

I have the following configuration:

• http server: Apache/2.4.18 (Ubuntu)
• application server: Wildfly 9.0.2
• mod_cluster: 1.3

Wildfly Configuration (relevant fragments):

mod_cluster subsystem:

    <subsystem xmlns="urn:jboss:domain:modcluster:2.0">
        <mod-cluster-config advertise-socket="modcluster"
                            proxies="mc-prox1"
                            advertise="false"
                            sticky-session-force="true" load-balancing-group="mycluster" connector="ajp">
            <dynamic-load-provider>
                <load-metric type="cpu"/>
            </dynamic-load-provider>
        </mod-cluster-config>
    </subsystem>

outbound-socket-binding:

    <outbound-socket-binding name="mc-prox1">
        <remote-destination host="192.168.0.71" port="5555"/>
    </outbound-socket-binding>

[EDIT]

I should have included ajp configuration:

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:1500}">
    <socket-binding name="ajp" port="${jboss.ajp.port:0}" />
 .......
</socket-binding-group>

[EDIT2]

When I set ajp port to 8009, it works. I want to use custom port number. Does anyone have a clue how to do it?

Answer 1

It turned out I had the wrong binaries :/. After replacing them with the ones from the offical website, I managed to connect Wildfly with apache through AJP.
