Having trouble with a crashing webserver? Is MySQL or Apache eating up your RAM and trashing your drive swapping? Don’t worry, there are good tools to help you get started in tuning your LAMP server to avoid crashes.
There are two scripts that I find invaluable in getting me a first and fast opinion on the current status of the server. The trick is often to get the settings right so that they do not risk eating up your RAM for breakfast. Here are two scripts to help you get your MySQL and Apache settings right for you.
This script will test your MySQL settings and suggest performance improvements. By using statistics from MySQL of current state of performance it will suggest modifications to your settings.
Inspired by MySQLtuner.pl Apachebuddy.pl does the same thing to Apache server settings. It checks your current settings and calculates average as well as maximum RAM usage and suggest improvements.
These script does of course not replace knowledge. Use them as a first opinion but then educate yourself about the settings before changing anything.
