Your my.cnf for the system will be at:
/etc/my.cnf
DirectAdmin does create a secondary my.cnf, but it's only used for the mysqldump calls. It's found at/usr/local/directadmin/conf/my.cnf
and should not be changed as it's overwritten regularly (based on the mysql.conf in the same directory).Apart from those 2 my.cnf files, you should not have any my.cnf files anywhere else.
Common "bad" my.cnf files are:
1)
/etc/mysql/my.cnf
You shouldn't have this file.. and you shouldn't even have a /etc/mysql directory, as it will conflict with your /etc/my.cnf.2)
/root/.my.cnf
This should not exist as our call to mysqldump will find it. Often admin's will have a user/password in that file, which breaks our calls to mysqldump.In your 2 my.cnf files, only /usr/local/directadmin/conf/my.cnf should have a user/password value. Â No other my.cnf file should have a user/pass set in it.
