Tup tup tup. That's what is called an assertion, man :).
The current state of the artr for MySQL is to use an NBD cluster. You can use
LVS to load-balance connections to your MySQL servers. You need a small
management server to manage it.
Now, to check whether a MySQL server is available or not, you have two
solutions (assuming you choose Keepalived):
Use a TCP_CHECK that will detect if the server accepts connections.
Use the check_mysql from nagios-plugins embedded in a MISC_CHECK script.
Probably you can do more complicated things with THC but, I didn't find time
yet to test it, so, I can't help.
François (et hop).
