              yum install rgmanager lvm2-cluster gfs2-utils -y

Note that installing only the rgmanager will pull in all necessary dependencies to create an HA cluster from the HighAvailability channel. The lvm2-cluster and gfs2-utils packages are part of ResilientStorage channel and may not be needed by your site.
On both nodes install:

        
              yum groupinstall 'High Availability' 'Resilient Storage' -y

On main web management server

        
              yum install luci -y

On both nodes:

        
              # service ricci start
Starting system message bus:                               [  OK  ]
Starting oddjobd:                                          [  OK  ]

On main node:

        
              # service luci start
Adding following auto-detected host IDs (IP addresses/domain names), corresponding to `mysql-cluster-1' address, to the configuration of self-managed certificate `/var/lib/luci/etc/cacert.config' (you can change them by editing `/var/lib/luci/etc/cacert.config', removing the generated certificate `/var/lib/luci/certs/host.pem' and restarting luci):
        (none suitable found, you can still do it manually as mentioned above)
 
Generating a 2048 bit RSA private key
writing new private key to '/var/lib/luci/certs/host.pem'
Start luci...                                              [  OK  ]
Point your web browser to https://mysql-cluster-1:8084 (or equivalent) to access luci

Add the following IP table rules to your servers:

        
              iptables -I INPUT 1 -p tcp --dport 5404 -j ACCEPT
iptables -I INPUT 1 -p tcp --dport 5405  -j ACCEPT

In your browser go to the following address and log in using the servers root account:

        
              https://x.x.x.x:8084

Once you have located the 'Create New Cluster' section, enter the parameters for the cluster you are creating
