One of the most common sources of site performance degradation is poor database optimization. While it is possible to optimize databases by manual inspection, this process may be prohibitively time consuming. To assist with this, MySQL Tuner was designed to make database optimization easier. In this guide, we will explore the basics of tuning MySQL databases with MySQL Tuner in order to optimize your MySQL service for faster queries and load times on your website. Please note that you will need to log into the command line interface as the root user to continue on with this tutorial.
MySQL Tuner
MySQL Tuner is a script that checks for fragmented database tables that need to be repaired, provides uptime statistics, and reviews the database for security issues. Written in PERL, MySQL Tuner is often used to help optimize databases and increase efficiency in database queries. By tuning MySQL databases, you can reduce site load times and increase the overall performance of the site itself. If your site relies heavily on database queries, proper optimization is key. The good news is that tools such as MySQL Tuner exist as easy-to-use database optimization resources.
