In this tutorial, we will show you how to install MySQL Server on your Debian 10. For those of you who didn’t know, MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. 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 web servers.
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 Server on a Debian 10 (Buster) server.
Prerequisites
- A server running one of the following operating systems: Debian 10 (Buster).
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install MySQL Server on Debian 10 Buster
Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt-get commands in the terminal:
apt update apt upgrade
Step 2. Installing MySQL.
MySQL team provides official MySQL PPA for Debian. You can download and install the package on your Debian system, which will add a PPA file to your system:
wget http://repo.mysql.com/mysql-apt-config_0.8.13-1_all.deb sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb
The package installer will prompt you to select the MySQL repository. Based on your selection, the installer will configure repositories to receive the appropriate version of MySQL.
Then, update the package list with and install the MySQL server package by running:
sudo apt update 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 status mysql
Step 3. Securing MySQL.
After the installation of MySQL is complete, you may need to secure your new MySQL. By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL:
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 the latest version of MySQL Server on the Debian 10 Buster server. For additional help or useful information, we recommend you check the official MySQL website.
