[keycloak-user] 1.1 Beta2 in Wildfly cluster

[Marek Posolda]

Are you using shared database among both cluster nodes? Also when you 
start node1 and then start node2, you should see some message similar to 
this in the log of node1, which indicates that cluster nodes are connected:

wfnode_1 | 11:28:30,888 INFO 
[org.infinispan.remoting.transport.jgroups.JGroupsTransport] 
(Incoming-1,shared=udp) ISPN000094: Received new cluster view: 
[wfnode1/web|1] (2) [wfnode1/web, wfnode2/web]
wfnode_1 | 11:28:33,767 INFO 
[org.infinispan.remoting.transport.jgroups.JGroupsTransport] 
(Incoming-10,shared=udp) ISPN000094: Received new cluster view: 
[wfnode1/keycloak|1] (2) [wfnode1/keycloak, wfnode2/keycloak]



For more logging of which provider is used by keycloak-server.json, you 
can enable DEBUG logging for keycloak in standalone-full.xml (or 
domain.xml or whatever you are using):

                 <logger category="org.keycloak">
                     <level name="DEBUG"/>
                 </logger>

Also I think that editing file 
|standalone/configuration/keycloak-server.json is just for standalone, 
but probably doesn't work for wildfly domain.

Maybe you can first try if cluster works in standalone configuration. If 
it helps, we can figure the domain later.
