MySQLTuner - An excellent free MySQL tool
Some thoughts on MySQLTuner and how to go about setting it up
MySQLTuner is a fairly small perl script that you can run on the linux box that contains your MySQL setup.
It quickly checks your configuration and produces an actionable report of recommendations.
You shouldn’t just blindly follow exactly what it recommends, but it did point out some glaring omissions in one of my setups and it will certainly give you some food for thought.
Running the script is very easy, to get everything setup you run through the following steps;
- Grab the script
wget mysqltuner.pl -O mysqltuner.pl
- Set permissions on it to allow you to execute it
chmod +x mysqltuner.pl
- Run it
wget works because the owner owns the domain mysqltuner.pl, it was a very clever idea since perl scripts are commonly given the extension .pl
Given how quick it is to install and run I am not sure why you wouldn’t give it a go.
