In this tutorial, we will show you how to install MariaDB on your Debian 9. 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 MariaDB database management system on a Debian 9 (Stretch) server.
Prerequisites
- A server running one of the following operating systems: Debian 9 (Stretch).
- 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 useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install MariaDB on Debian 9 Stretch
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.
First, Add MariaDB Repositories, use the below commands to add MariaDB Repositories on Debian systems:
apt-get install software-properties-common dirmngr apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8 add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://sumberterbuka.beritagar.id/mariadb/repo/10.2/debian stretch main'
Once the key is imported and the repository added you can install MariaDB using the following command:
apt-get update apt-get install mariadb-server mariadb-client
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 9 (Stretch). For additional help or useful information, we recommend you to check the official MariaDB website.
