[CentOS] How to setup RAID 5 + 1 hot spare?

Hello everyone,

I am new to this group so please forgive me if this question has been
already asked.

With four identical hard drives, I want to setup RAID 5 + 1 hot spare by a
fresh CentOS (6.3) installation.

I have read this article (
http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-raid-config.html)
and watched this video (http://www.youtube.com/watch?v=qm3MkuTfDLw), now I
have the basic ideas.

However, due to my limited experience and knowledge on this area, I am
still confused.

To make things easier, I only need a swap and a `/' partition.

Could you give me any hint on this? What should I read to get the basic
knowledge? How can I setup a simple RAID 5 + hot spare?
