How to Optimize MySQL

CentOS
There is a default my.cnf that comes with mysql (4+5) that will make mysql run a bit quicker if you have 2+ gig of ram cp -f /usr/share/mysql/my-large.cnf /etc/my.cnfThere is also my-huge.cnf, or my-medium.cnf depending on your hardware setup.   Check the contents of these my*.cnf files for the one that’s right for you.

*NOTE* the log-bin option is enabled  by default.  This will quickly use a lot of disk space.  It’s recommended to comment out the log-bin line from your /etc/my.cnf, if it exists.

 

Remember to restart mysql when you are done with your my.cnf tweaking:

Redhat:/sbin/service mysqld restart

FreeBSD:/usr/local/etc/rc.d/mysqld restart
