9.2. Red Hat Cluster configuration

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.

[Note]Note

For more information about configuring Red Hat clusters, see Red Hat’s documentation on the Red Hat Cluster and GFS.

9.2.1. The cluster.conf file

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.
