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(Oracle’s SPARC/IBM’s 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.
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” using yum repository.By default it installs “cman” and “ricci”.
[root@UANODE1 ~]# yum install rgmanager

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.
