pcs relies on pcsd running on all nodes.

Make sure pcs is installed on all nodes, and pcsd is enabled to start at
boot (via service or systemctl depending on which you are using). Then
set a password (same on all nodes) for the hacluster user. Finally, run
"pcs cluster auth <nodenames>" on the machine you want to run pcs from,
and give it the hacluster user/pass.

You may want to review the Clusters From Scratch documentation to see
other common configuration that needs to be done (firewall, SELinux,
hostnames, etc.):
