Hi, using mysql 5.0.77 on Centos 5.6 I was required me to do the following due mysql.sock.

#ln -s /var/lib/mysql /data/mysql
#chown -R mysql.mysql /var/lib/mysql

Using mysql 4.X this step was not required.

Nice job on the howto.

anyway, thanks again!

Your right. Heartbeat is so last year, but it is in the Redhat release. I'm a DBA not a sysadmin. (Well really I'm both, see linuxfanboy.com, but we have separation of duties where I work.) Sometimes to get the sysadmin to you have to right them instructions. I will be reviewing Pacemaker, Corosync and Continuent's Tungsten sometime.

You’re seriously using Heartbeat in R1 mode? Time to step a few years forward into the present and check out Pacemaker and Corosync.
