Installing MySQL on Fedora Linux using MariaDB. Since MySQL was sold to Oracle. MariaDB is a fork and open source version of MySQL.

Install MySQL on Fedora using MariaDB

$ sudo dnf install mariadb mariadb-server mariadb-devel

Start MariaDB

Run this to start the process:

$ sudo systemctl start mariadb

Later if you try to connect to MariaDB and get this error:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket

This means that you didn’t start the process. Or you restarted the machine and the process didn’t start.

For reference:

  • Stop: sudo systemctl stop mariadb
  • Restart: sudo systemctl restart mariadb
  • Status: sudo systemctl status mariadb
  • Start at boot: sudo systemctl enable mariadb

This the output of checking status with sudo systemctl status mariadb:

Config MariaDB

$ sudo mysql_secure_installation

In order to log into MariaDB to secure it, we’ll need the current password for the root user. If you’ve just installed MariaDB, and haven’t set the root password yet, you should just press enter here.

Enter current password for root (enter for none):

Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have your root account protected, so you can safely answer ‘n’.

Switch to unix_socket authentication [Y/n] n
... skipping.

You already have your root account protected, so you can safely answer ‘n’.

Change the root password? [Y/n] n
