How To Install MariaDB on CentOS 8

In this tutorial, we will show you how to install MariaDB on CentOS 8. For those of you who didn’t know, MariaDB is an open-source, multi-threaded relational database management system, a backward-compatible replacement for MySQL.

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 MariaDB on a CentOS 8 server.

Prerequisites

• A server running one of the following operating systems: CentOS 8 server.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• 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 MariaDB on CentOS 8

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

sudo dnf update

Step 2. Installing MariaDB on CentOS 8.

MariaDB is a drop-in replacement for MariaDB. It is a robust, scalable, and reliable SQL server that comes a rich set of enhancements. We will also be using yum to install MariaDB:

sudo dnf install mariadb-server

By default, MariaDB is not hardened. You can secure MariaDB 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 MariaDB:

mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

Remove anonymous users? [Y/n] y
 ... Success!

Disallow root login remotely? [Y/n] y
 ... Success!

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...
Thanks for using MariaDB!

To log into MariaDB, use the following command (note that it’s the same command you would use to log into a MariaDB database):

mysql -u root -p

Also try to create a new database, user, and assign privileges to a database:

## CREATE DATABASE
MariaDB [(none)]> CREATE DATABASE mydb;
 
## CREATE USER ACCOUNT
MariaDB [(none)]> CREATE USER 'dbuser'@'localhost' IDENTIFIED BY 'secret-passwd';
 
## GRANT PERMISSIONS ON DATABASE
MariaDB [(none)]> GRANT ALL ON mydb.* TO 'dbuser'@'localhost';
 
##  RELOAD PRIVILEGES
MariaDB [(none)]> FLUSH PRIVILEGES;

Then, restart the MariaDB database server and enable it to start on system start-up using:

sudo systemctl restart mariadb
sudo systemctl status mariadb
sudo systemctl enable mariadb
