By default Linux CentOS or other Linux Distro installation, MySQL data directory is stored in /var/db/mysql, how can I change it to other directory in example /db/mysql?

It is always better to have MySQL Data Directory store in a specific partition/drive. It will help on performance and better management and scalability. You change change the data store directory in Linux by editing /etc/my.cnf file.

Edit /etc/my.cnf file


# vi /etc/my.cnf

Change the data directory structure


datadir=/db/mysql
socket=/db/mysql/mysql.sock

After the file has been updated, restart MySQL service.

Who run more than 10 Linux servers with different version of Linux Distro? We all know there are many type of Linux distro such as Ubuntu, Centos, Gentoo, Fedora, debian, OpenSUSE and etc. Every single distro runs on different version and etc. Sometime I am having problem to remember what Linux distro is running on my DNS server or Mail Server, and what Linux version is it on now. There are two methods to find linux version on your server.

To check Linux distro on your server


shell> cat /etc/issue

To check Linux Version and distro on your server
