1.1.2. Installing Red Hat Cluster software

To install Red Hat Cluster software, you must have entitlements for the software. If you are using the

Conga configuration GUI, you can let it install the cluster software. If you are using other tools to

configure the cluster, secure and install the software as you would with Red Hat Enterprise Linux

software.

1.1.3. Configuring Red Hat Cluster Software

Configuring Red Hat Cluster software consists of using configuration tools to specify the relationship

among the cluster components. Figure 1.2, “Cluster Configuration Structure” shows an example of the

hierarchical relationship among cluster nodes, high-availability services, and resources. The cluster

nodes are connected to one or more fencing devices. Nodes can be grouped into a failover domain for a

cluster service. T he services comprise resources such as NFS exports, IP addresses, and shared GFS

partitions.
