Both of them installed and started:
yum install pacemaker pcs passwd hacluster (Set the same password) systemctl enable pcsd.service systemctl start pcsd.service
When authenticating the cluster nodes:
(On node 1) psc cluster auth 192.168.0.1 192.168.0.2 (Output) Username: hacluster Password: Error: Unable to communicate with 192.168.0.2 192.168.0.1: Authorized
Why can't authenticate node2?
