How To Install MySQL on CentOS 8

In this tutorial, we will show you how to install and configuration of MySQL on CentOS 8. 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 CentOS 8 server.

Prerequisites

• A server running one of the following operating systems: CentOS 8.
• 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 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 MySQL on CentOS 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf clean all
sudo dnf update

Step 2. Install MySQL on CentOS 8.

You need to enable the repository package of MySQL on your system:

dnf install wget
wget https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm
rpm -ivh mysql80-community-release-el8-1.noarch.rpm

Next, Use dnf the command installs the latest version of MySQL:

sudo dnf 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 CentOS 8 server. For additional help or useful information, we recommend you check the official MySQL website.
