B.2. Pacemaker Installation in Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7
B.2. Pacemaker Installation in Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 Red Hat Enterprise Linux 6.5 and later releases support cluster configuration with Pacemaker, using the pcs configuration tool. There are, however, some differences in cluster installation between Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 when using Pacemaker. The following commands install the Red Hat High Availability Add-On software packages that Pacemaker requires in Red Hat Enterprise Linux 6 and prevent corosync from starting without cman . You must enter these commands on each node in the cluster. On each node in the cluster, you set up a password for the pcs administration account named hacluster , and you start and enable the pcsd service. On one node in the cluster, you then authenticate the administration account for the nodes of the cluster. In Red Hat Enterprise Linux 7, you run the following commands on each node in the cluster to install the Red Hat High Availability Add-On software packages that Pacemaker requires, set up a password for the pcs administration account named hacluster , and start and enable the pcsd service, In Red Hat Enterprise Linux 7, as in Red Hat Enterprise Linux 6, you authenticate the administration account for the nodes of the cluster by running the following command on one node in the cluster. For further information on installation in Red Hat Enterprise Linux 7, see Chapter 1, Red Hat High Availability Add-On Configuration and Management Reference Overview and Chapter 4, Cluster Creation and Administration .
