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.
