WildFly 10 Jgroups allways binding to localhost interface

[isurul]

Hi I'm trying to develop a clustered application that uses Infinispan for caching. First I tried to run in replicated mode by starting two instance of wildfly using the localhost as binding interface (with port offsets). This worked fine. But once I start the server using interface IP, cluster is not forming. Still I can access other services using the interface IP. I tried to telnet the Jgroups port using interface IP address and it failed. But telnetting to localhost works for Jgorups port.

(Then entered localhsot[port] IP's to initial host configuration element in tcpping. Then cluster formation worked.)

So my question is why does it bind to localhost even after starting wildfly using interface IP.

Here is my configuration. (I cant use UDP, therefore need to use tcpping for cluster formation)

Started the wilfly server using

standalone.bat -Djboss.server.base.dir=../standalone_isuru -c standalone-full-ha.xml -b 192.168.17.33 -Djboss.node.name=isuru -Djboss.socket.binding.port-offset=1 

Jgourps configuration

Just skimming through the post, you can just specify -bprivate=...

If you look closely at the interfaces configuration you will see that there are 3 interfaces and jgroups bindings are using the private one:

...

    <interfaces>

        <interface name="management">

            <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>

        </interface>

        <interface name="public">

            <inet-address value="${jboss.bind.address:127.0.0.1}"/>

        </interface>

        <interface name="private">

            <inet-address value="${jboss.bind.address.private:127.0.0.1}"/>

        </interface>

    </interfaces>

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

...

        <socket-binding name="jgroups-tcp" interface="private" port="7600"/>

        <socket-binding name="jgroups-tcp-fd" interface="private" port="57600"/>

        <socket-binding name="jgroups-udp" interface="private" port="55200" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45688"/>

        <socket-binding name="jgroups-udp-fd" interface="private" port="54200"/>

Thanks for the reply. Will check on tomorrow and let you know

Thanks man, it works now !!!!!. I didn't see this anywhere in documentation. maybe I should read more.

Hi!

I have the same problem. Can you specify how did you solve this adress bind problem?

Many thanks

Give it a try using -bprivate <specific ip addr> or -Djboss.bind.address.private=<specific ip addr> like the following:

---

${WILDFLY_HOME}/bin/standalone.sh -c standalone-ha.xml -bprivate <specific ip addr>

---

It worked! Many thanks!!
