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 through the step by step installation MariaDB on a CentOS 8 server.
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:
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'; ## 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
Congratulations! You have successfully installed MariaDB. Thanks for using this tutorial for installing MariaDB on CentOS 8 system. For additional help or useful information, we recommend you to check the official MariaDB website.
