How To Install MariaDB on Ubuntu 16.04

In this tutorial, we will show you how to install and configuration of MariaDB on your Ubuntu 16.04 server. 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. I will show you the step-by-step installation of MariaDB on the Ubuntu 16.04 LTS (Xenial Xerus) server.

Prerequisites

• A server running one of the following operating systems: 16.04 LTS (Xenial Xerus).
• 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 Ubuntu 16.04

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

apt-get update
apt-get upgrade

Step 2. Installing MariaDB.

Installing MariaDB is as simple as running just one command below:

apt-get install mariadb-server

If you want to install MariaDB 10.x Which is not included in the distribution repository. We going to add the MariaDB repo to our system:

sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://ftp.utexas.edu/mariadb/repo/10.1/ubuntu xenial main

Once the key is imported and the repository added you can install MariaDB with:

apt-get update
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
