Installing cluster management

Perform this procedure to install the cluster management software.
  1. Log in to the primary node as root, or as a user with superuser privileges.
  2. In a separate window, log in to the secondary node as root, or as a user with superuser privileges.
  3. On both nodes, extract and install the cluster management packages.
    1. Extract the packages.
      cd /tmp && tar xzf ./downloads.tgz
    2. Install the packages.
      yum --disablerepo=\* install -y ./downloads/*.rpm
  4. On both nodes, install the Pacemaker resource agent for Control Center.
    Pacemaker uses resource agents (scripts) to implement a standardized interface for managing arbitrary resources in a cluster. Zenoss provides a Pacemaker resource agent to manage the Control Center master host.
    yum install -y --disablerepo=\* \
      /opt/zenoss-repo-mirror/serviced-resource-agents-1.0.0-1.x86_64.rpm
  5. On both nodes, start and enable the PCS daemon.
    systemctl start pcsd.service && systemctl enable pcsd.service
  6. On both nodes, set the password of the hacluster account.
    The Pacemaker package creates the hacluster user account, which must have the same password on both nodes.
    passwd hacluster
