Abandoned - 2-Node EL5 Cluster

AN!Wiki :: How To :: Abandoned - 2-Node EL5 Cluster

Overview

This first cluster How-To will cover building a two node cluster. This is a good place to start as the step up to 3+ node is significant. Having a working 2-node will give you a much stronger foundation for that step up. In fact, this How-To will be a prerequisite for the 3+ Node How To.

The initial cluster will be built for two purposes;

• VM Hosting; Make a virtual server "float" between two real servers for high-availability.
• iSCSI Target on top of LVM + DRBD.

Progress

Feb. 02, 2010 I finally got the hardware in place to start building the cluster I will need to create this How To. Progress should now really start!

Oct. 15, 2009 I've gotten permission from Canada Equity's owner to use the docs I created for them on this public How To. I will post here once it is complete and signed off on.

OS Install

Start with a stock CentOS 5 install. This How-To uses CentOS 5.4 x86_64, however it should be fairly easy to adapt to other CentOS 5*, RHEL5 or other RHEL5-based distributions.

Kickstart

This is a sample kickstart script used by this paper. Be sure to set your how password string and network settings.

Warning! This kickstart script will erase your hard drive! Adapt it, don't blindly use it.
