To install Red Hat Enterprise with Cluster Suite, take CDs or DVD and boot from it.

We are going to see step by step the interesting components.

Language 

Set the English language and not French to have more verbose output during future problems.

Keyboard 

Keep the French keyboard

Partitioning (do the same partitioning on all the cluster nodes)

List of packages installation 

base
base-x
kde-desktop or gnome-desktop
editors (only vim)
mail-server (- spamassassin)
development-tools
compat-arch-development
admin-tools (+ sysstem-boot-config)
system-tools
compat-arch-support

After rebooting, install these packages from the cluster suite (cdrom/RedHat/RPMS). Warning: pay attention for SMP; if not SMP servers, do not install it, install other relative packages.

ccs
cman
cman-kernel-smp
dlm
dlm-kernel-smp
fence
gulm
ipvsadm
magma
magma-plugins
perl-Net-Telnet
rgmanager
system-config-cluster

Or run this command directly:

1

rpm -ivh --aid ccs-1.0.7-0.x86_64.rpm cman-1.0.11-0.x86_64.rpm cman-kernel-smp-2.6.9-45.2.x86_64.rpm  dlm-kernel-smp-2.6.9-42.10.x86_64.rpm fence-1.32.25-1.x86_64.rpm gulm-1.0.7-0.x86_64.rpm ipvsadm-1.24-6.x86_64.rpm magma-1.0.6-0.x86_64.rpm magma-plugins-1.0.9-0.x86_64.rpm perl-Net-Telnet-3.03-3.noarch.rpm rgmanager-1.9.53-0.x86_64.rpm system-config-cluster-1.0.27-1.0.noarch.rpm dlm-1.0.1-1.x86_64.rpm

A little update might not be so bad (optional):

1

up2date -u

Modify the /etc/hosts like this on each node:

1
2
3

127.0.0.1               localhost.localdomain localhost
192.168.0.242           secondary.cluster.net secondary
192.168.0.241           primary.cluster.net primary

Here is an example of the cluster.conf file in /etc/cluster:

			<fs ref="disk2"/>
			<script file="/etc/init.d/ntpd" name="ntp"/>
		</service>
	</rm>
</cluster>

And of course, don’t forget to run services:

1
2
3
4

service ccsd restart
service cman restart
service fenced restart
service rgmanager restart

If you want to stop the cluster, do it in the reverse order:

1
2
3
4

service rgmanager stop
service fenced stop
service cman stop
service ccsd stop

It’s very important to stop in this order!
