How To Install MariaDB on Debian 8

In this tutorial, we will show you how to install and configuration of MariaDB on your Debian 8. For those of you who didn’t know, MariaDB is an open-source and cross-platform database engine and server, designed as a drop-in replacement for the well-known and powerful MySQL database engine used on numerous web servers around the world. The application is geared toward database professionals that are in search of a scalable, robust, reliable, and stable SQL server, a replacement for the MySQL database server.

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 Debian 8 (Jessie) server.

Prerequisites

• A server running one of the following operating systems: Debian 8 (Jessie).
• 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 MariaDB on Debian 8 Jessie

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt-get commands in the terminal:

apt-get update
apt-get upgrade

Step 2. Installing MariaDB.

By default MariaDB 5.x Series was included in all the Linux distribution but they didn’t include MariaDB 10.x series and if you want Add MariaDB Repositories, use the below commands to add MariaDB Repositories on Debian systems:

sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xcbcb082a1bb943db
sudo add-apt-repository 'deb [arch=amd64,i386] http://mirrors.opencas.cn/mariadb/repo/10.1/debian '$(lsb_release -cs)' main'

After refreshing the repository, just fire the below command to install MariaDB on your systems:

sudo apt-get update
sudo apt-get install mariadb-server

Once complete, you can verify MariaDB is installed by running the below command:

systemctl start mariadb
systemctl status mariadb

Step 3. Securing MariaDB after installation.

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

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

mysql -u root -p

Congratulations! You have successfully installed MariaDB. Thanks for using this tutorial for installing the MariaDB database management system on Debian 8 (Jessie). For additional help or useful information, we recommend you to check the official MariaDB website.
