Linux- How to Install Redhat Cluster Software ?Posted by: Lingeswaran R October 12, 2013 in Redhat Cluster, Redhat-LINUX

I have been trying to post about redhat cluster from quite long time.But today only I got a time to write

about it. Redhat Linux become quite popular and most of the low end and mid-range server are migrating

from Unix to Redhat Linux.Once of the recent survey stated that RISC servers(Oracles SPARC/IBMs

POWER) shipment is keep on reducing every year and X86 servers shipment has been increased rapidly.

Itanium(HP-UX) is not in that competition at all.Since Redhat Linux is emerging in the market and most of

the companies are building redhat cluster for High Availability.

So Let me start from Redhat Cluster packages installation and many more posts will follow about redhat

cluster configuration soon.

System Configuration:

UANODE1 cluster node 1 (192.168.2.200)



UANODE2 Cluster node 2 (192.168.2.201)

UACM - Management server for luci.

1. Login to both cluster nodes and install rgmanager usingyum repository.By default it installs cman

and ricci.

[root@UANODE1 ~]# yum install rgmanager

Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

Updating certificate-based repositories.

3.To configure the redhat cluster, we need to install luci on non cluster node(Hostname-UACM).So that

we will be having web interface accessibility in case of both cluster nodes down.

Note:You can also install luci on the cluster node but if the configured luci node is down,then you may

not able to manage cluster using luci.

[root@UACM ~]# yum install luci
