[keycloak-user] Keycloak Clustering, other instance logs me out

Wed Mar 30 06:52:29 EDT 2016

When you start the second instance, are you seeing something like this 
in log of both servers?

INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] 
(Incoming-10,shared=udp)
ISPN000094: Received new cluster view: [node1/keycloak|1] (2) 
[node1/keycloak, node2/keycloak]

If not, then clustering doesn't work properly and the servers doesn't 
form a cluster with each other. From the log you sent, there is just 
startup of one server, which indicates that clustering may not work.

Maybe multicast doesn't work in your network. Either disable 
firewall/selinux/whatever to have multicast working or switch to TCP 
JGroups channel instead of UDP. See the Wildfly and JGroups 
documentation for more details.

Also I personally use the virtual hosts to test clustering of 2 servers 
on same machine (Ie. have virtual servers like kc1:8080 and kc2:8080) . 
Using same host but differ just in port number ( host:8080 and host:8081 
) may causing mess with cookies, so
I am personally not using the setup like this.
