This section outlines the configuration steps necessary to get Red Hat Cluster running. Preparing your cluster configuration is fairly straightforward; all a DRBD-based Red Hat Cluster requires are two participating nodes (referred to as Cluster Members in Red Hat’s documentation) and a fencing device.

RHEL clusters keep their configuration in a single configuration file,
/etc/cluster/cluster.conf
. You may manage your
cluster configuration in the following ways:
Editing the configuration file directly. This is the most straightforward method. It has no prerequisites other than having a text editor available.
Using the system-config-cluster
GUI. This is a GUI application written in Python using Glade. It requires
the availability of an X display (either directly on a server console,
or tunneled via SSH).
Using the Conga web-based management infrastructure. The Conga infrastructure consists of a node agent ( ricci
)
communicating with the local cluster manager, cluster resource
manager, and cluster LVM daemon, and an administration web application
( luci
) which may be used to configure the cluster infrastructure
using a simple web browser.
