Generic active/passive clusters

Configuring a cluster using corosync and heartbeat means you have to write a start/stop and monitoring script for the service you are building the cluster for.

This script is very much like an "init.d" script, but you can't directly use an init.d script as heartbeat scripts use tri-state logic in stead of two-state logic. I.e., heartbeat controlled services are "running", "stopped" or "failed".

Install the cluster engine & resource manager

You need to perform the installation on each cluster node.

Add the EPEL repo to /etc/yum.repos.d:

    # rpm -Uhv http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm 

Add the Clusterlabs repo to /etc/yum.repos.d:

    # wget -O /etc/yum.repos.d/pacemaker.repo http://clusterlabs.org/rpm/epel-5/clusterlabs.repo

Now have yum install the cluster engine and resource managers. This will install loads of dependencies:

    # yum -y install pacemaker
