How to Install MySQL Server on Fedora

Free, open-source MySQL is one of the most popular database management systems. MySQL is used as a database backend for websites and web-based applications. It is very popular due to its stability, robustness, and ease of use. Also, MySQL is compatible with all major Linux operating systems, including Fedora, Debian, Ubuntu, CentOS, and more. It is primarily used with LAMP and LEMP stack to host web applications.

This post will show you how to install MySQL server on Fedora.

Step 1 – Add MySQL 8 Repository

The MySQL 8 package is not included in the Fedora official repository by default, so you will need to create a MySQL repo in your server. You can create it by running the following command.

rpm -ivh https://dev.mysql.com/get/mysql80-community-release-fc34-2.noarch.rpm
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

Next, verify the added repo using the following command.

dnf repolist all | grep mysql | grep enabled

You should see the MySQL repo in the following output.

mysql-connectors-community        MySQL Connectors Community            enabled
mysql-tools-community             MySQL Tools Community                 enabled
mysql80-community                 MySQL 8.0 Community Server            enabled

Step 2 – Install MySQL 8

You can now install the MySQL community server package using the following command.

dnf install mysql-community-server -y

Once MySQL is installed, start and enable the MySQL service using the following command.

systemctl enable mysqld
systemctl start mysqld

Next, check the status of the MySQL service with the following command.

systemctl status mysqld

You should see the following output.

● mysqld.service - MySQL Server
     Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
