In this tutorial, we will show you how to install MySQL on Ubuntu 20.04 LTS. For those of you who didn’t know, MySQL is the most popular open-source relational database management system. The MySQL source code is freely available because it was originally developed as freeware. MySQL is written in C and C++ and is compatible with all major operating systems. MySQL can be used for a variety of applications but is most commonly found on the popular LAMP and LEMP stacks.
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 of MySQL on a Ubuntu 20.04 (Focal Fossa) server.
Install MySQL on Ubuntu 20.04 LTS Focal Fossa
Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.
sudo apt update sudo apt upgrade
Step 2. Installing MySQL on Ubuntu 20.04.
To install the MySQL server run the following commands:
sudo apt install mysql-server
Once complete, you can verify MySQL is installed by running the below command:
sudo systemctl status mysql sudo systemctl start mysql sudo systemctl enable mysql
You can confirm that the MySQL client was installed successfully and see what version your system is running with this command:
mysql -V
Step 3. Securing MySQL.
The first thing you’ll want to do after installing your MySQL server is secure it via the following command:
mysql_secure_installation
Configure it like this:
- Set root password? [Y/n] y - Remove anonymous users? [Y/n] y - Disallow root login remotely? [Y/n] y - Remove test database and access to it? [Y/n] y - Reload privilege tables now? [Y/n] y
To log in to MySQL, use the following command (note that it’s the same command you would use to log into a MySQL database):
mysql -u root -p
One of the most important things when running MySQL on a production server is to get the most out of its performance. If you are a beginner and you do not know how to tune your MySQL server, you can start with a program called MySQLTuner. It will help you to analyze your server and to tune MySQL for better overall performance.
Congratulations! You have successfully installed MySQL. Thanks for using this tutorial for installing MySQL server in Ubuntu 20.04 Focal Fossa system. For additional help or useful information, we recommend you check the official MySQL website.
