MySQL: where is the my.cnf file located on Debian (Ubuntu), CentOS (RedHat), and FreeBSD

Practice



Lost the my.cnf file (MySQL server configuration) on your new operating system? Here's a quick note on where to look for it depending on the OS:


Debian (and its clone ubuntu): /etc/mysql/my.cnf

CentOS (or RedHat): /etc/my.cnf

FreeBSD: nope, it's not there by default :) just isn't.


To get this file on FreeBSD: go to the /usr/local/share/mysql/ folder and copy whichever one you like to /usr/local/usr/my.cnf:

$ cd /usr/local/share/mysql/
$ sudo cp my-huge.cnf /usr/local/etc/my.cnf


In this example we took the my-huge.cnf file to copy, but you can take any file you like that suits your customization of the settings.

Applies to: MySQL 5.x; Debian/ubuntu, CentOS/RedHat, FreeBSD
