I’m managing a website that have 1.000.000 uniq visitors per day and at the moment it’s been supported with 5 servers, one of them MySQL. The problem I have is when mysql server goes down to do some maintenance or if it falls down everything else is screwed up.

I’ve been looking for a how-to mysql cluster but only could find outdated articles like this:
http://dev.mysql.com/tech-resources/…o-servers.html

Im using RHEL 5.4 on all my servers + native RHEL MySQL 5.0.77

Can anyone share a mysql cluster how to?

Thanks.
