[wildfly-dev] 2 instance cluster in master/slave

[Arun Gupta]

Trying to following the instructions at:

https://docs.jboss.org/author/display/WFLY8/WildFly+8+Cluster+Howto

This shows how to setup a 2-instance cluster in master/slave where
master is on my laptop and slave is on a Raspi. Couple of questions
...

1). Why the following entry is still referring to 9999 ? Shouldn't it be 9990 ?

<domain-controller>
   <remote host="10.211.55.7" port="9999"/>
</domain-controller>

FTR it only works with 9999, not with 9990.

Domain Controller shows the message:

[Host Controller] 15:36:22,811 INFO  [org.jboss.as.domain] (Host
Controller Service Threads - 28) JBAS010918: Registered remote slave
host "slave", WildFly 8.1.0.CR2 "Kenny"


2). Master is throwing the following exception:

Same error for server-two as well.

Trying to explicitly start server-three on slave gives the same error.

This is all using 8.1 CR2.

Any idea what might be wrong ?

Thanks
Aru
