How To Install MySQLTuner on Ubuntu

In this tutorial, we will show you how to install and configuration of MySQLTuner on your Ubuntu server.  For those of you who didn’t know, MySQLTuner is a valuable tool for MySQL database administrators and developers to optimize the performance of their MySQL servers. It provides detailed information about the server configuration and performance metrics, as well as recommendations for improving performance. By regularly running MySQL Tuner, administrators can ensure that their MySQL servers are running optimally and avoid potential performance issues.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation MySQLTuner on a Ubuntu server.

Prerequisites

• A server running one of the following operating systems: Ubuntu and any other Debian-based distribution.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for the MySQLTuner script.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MySQLTuner on Ubuntu

Step 1. First, make sure that all your system packages are up-to-date by running the following aptcommands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install perl

Step 2. Installing MySQLTuner on Ubuntu.

By default, MySQLTuner is not available on the Ubuntu base repository. Now run the following command below to download the latest version of MySQLTuner from the GitHub page to your Ubuntu system:

wget https://github.com/mysqltuner/mysqltuner.pl/raw/master/mysqltuner.pl

Move the downloaded file to the /usr/local/bin/ directory by running the following command:

sudo mv mysqltuner.pl /usr/local/bin/

Next, set the correct permissions for the file by running the following command:

sudo chmod +x /usr/local/bin/mysqltuner.pl

Finally, run the following command to start MySQL Tuner:

sudo mysqltuner.pl

As a result, you should get something like this:

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Reduce or eliminate unclosed connections and network issues
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
Variables to adjust:
    query_cache_type (=4)
    tmp_table_size (> 18M)
    max_heap_table_size (> 18M)

When you run mysqltuner, it will show you a report with many suggestions. Just follow them. The exact suggestion will vary so it’s hard to cover all of them here. Rather I will give you some notes some of which are offered by mysqltuner itself.
