Note that remove RPM files may be misleading. There probably aren't any mysql related files ending in rpm on your server. You can use YUM to remove MySQL, but I'd recommend leaving it on the server; it'll be updated as required when you run yum update, and won't be run anyway.
I was setup mysql on dedicated server and modyfy mysql.conf:
access_host=mysqlhost
user=da_admin
passwd=mypass
And restart DA
But when I try use mysql management in panel under user, I got this error:
Error connecting to MySQL: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Why panel ignore this settings and wan use socket to access?
