4.2.2. Setup Pacemaker Remote
On the HOST machine run these commands to generate an authkey and copy it to the /etc/pacemaker folder on both the host and guest.
# mkdir /etc/pacemaker
# dd if=/dev/urandom of=/etc/pacemaker/authkey bs=4096 count=1
# scp -r /etc/pacemaker root@192.168.122.10:/etc/
Now on the GUEST install pacemaker-remote package and enable the daemon to run at startup. In the commands below you will notice the pacemaker and pacemaker_remote packages are being installed. The pacemaker package is not required. The only reason it is being installed for this tutorial is because it contains the a Dummy resource agent we will be using later on to test the remote-node.
# yum install -y pacemaker pacemaker-remote resource-agents
# systemctl enable pacemaker_remote.service
Now start pacemaker_remote on the guest and verify the start was successful.
# systemctl start pacemaker_remote.service
# systemctl status pacemaker_remote
