A.2. Cluster Creation with Pacemaker in Red Hat Enterprise Linux Release 6.5 and Red Hat Enterprise Linux Release 6.6 (and later)
To create a Pacemaker cluster in Red Hat Enterprise Linux 6.5, you must create the cluster and start the cluster services on each node in the cluster. For example, to create a cluster named
my_cluster that consists of nodes z1-rhel65.example.com and z2-rhel65.example.com and start cluster services on those nodes, run the following commands from both z1-rhel65.example.com and z2-rhel65.example.com.
pcs cluster setup --name my_cluster \ z1-rhel65.example.com z2-rhel65.example.com pcs cluster start
[root@z1-rhel65]# pcs cluster setup --name my_cluster \
z1-rhel65.example.com z2-rhel65.example.com
[root@z1-rhel65]# pcs cluster startpcs cluster setup --name my_cluster \ z1-rhel65.example.com z2-rhel65.example.com pcs cluster start
[root@z2-rhel65]# pcs cluster setup --name my_cluster \
z1-rhel65.example.com z2-rhel65.example.com
[root@z2-rhel65]# pcs cluster start
In Red Hat Enterprise Linux 6.6 and later, you run the cluster creation command from one node of the cluster. The following command, run from one node only, creates the cluster named
my_cluster that consists of nodes z1-rhel66.example.com and z2-rhel66.example.com and starts cluster services on those nodes.
pcs cluster setup --start --name my_cluster \ z1-rhel66.example.com z2-rhel66.example.com
[root@z1-rhel66]# pcs cluster setup --start --name my_cluster \
z1-rhel66.example.com z2-rhel66.example.com
