I have 2 servers which I run keycloak on.
node1 ip: 10.12.201.3
node2 ip: 10.12.201.4
I run keycloak asi standalone-ha.xml on both servers. I also have zevenet load balancer which distributes traffic to both nodes via ip 10.12.203.13:8080. I have 2 issues which I would like to solve:
1.issue:
when I login to keycloak via 10.12.203.13:80 and I stop the process on the server where the session is opened I will be disconnected from the session and I have to login again to keycloak. Is it possible to solve that? I want to achieve that I would not be disconnected when one of the servers goes down.
2.issue: when I login to keycloak via 10.12.203.13:80 and delete on of servers from load balancer I am also disconnected from the session and I have to login again. Please is it possible to solve that?
Please if you can help me write a specific lines of xml which I have to include into standalone-ha.xml config.
my standalone-ha.xml config looks like this now:
<?xml version='1.0' encoding='UTF-8'?>
