[rt-users] Eeek! RT is unable to connect to database

[Jerrad Pierce]

I applied some of the recommendations from mysqltuner.pl (since backed out),
including the users able to connect (to the test database) without
authentication
(not reversed), and now RT cannot connect to the database:

[Tue Feb 10 13:29:12 2009] [error] [client 129.44.190.12] Connect
Failed Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (13)
at /opt/rt3/bin/../lib/RT.pm line 204

The socket is there, I can connect with mysql -u rt_user -p, and with
a test perl script via DBI.
I'm at a loss, and have found nothing but these obvious bits in the
list archives, any thoughts?
