I'm just beginning to consider using the Clustering available with
CentOS. We are going to spec out some new hardware, and after
reading most of the Clustering manuals, I have a small question
about MySQL.
I would like to run High Availability MySQL, in other words,
similar to how you can run HA HTTPD and the like. The catch seems
to be if I run MySQL on an individual server, with common MySQL
replication to another server, how do failovers work? I see a real
problem with table locking and the like. Is there a way to run
multiple MySQL servers that get removed from the cluster as opposed
to failing over when using the newer MySQL versions (I am running
3.23 now, so a little behind)?
After all the discussions regarding MySQL-style clustering
(multi-master etc), what about a "classic" HA cluster for MySQL? Since
the OP mentioned high availability, wouldn't the simplest solution be
failover clustering (ie. single master with failover, shared storage,
fenced nodes etc) via Centos CS?
As I haven't done this myself I can't really comment further, but does
anyone else on the list have experience engineering a Centos Cluster
Suit failover cluster for MySQL?
cheers

I use a MySQL high-availability setup in a 800-1000 concurrent
connection environment. We use DRBD and Heartbeat and it's
bulletproof. See
http://marksitblog.blogspot.com/2007/07/mysql-5-high-availability-with-drbd-8.html for an example
configuration.
