How To Install MariaDB on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install MariaDB on your Ubuntu 18.04 LTS. 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 in Ubuntu 18.04 LTS Bionic Beaver.

Prerequisites

• A server running one of the following operating systems: Ubuntu 18.04, and any other Debian-based distribution like Linux Mint.
• 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 18.04 LTS Bionic Beaver

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 on Ubuntu 18.04 LTS.

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

sudo apt install mariadb-server mariadb-client

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] http://mirror.zol.co.zw/mariadb/repo/10.3/ubuntu bionic main'

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

sudo apt update
sudo apt install mariadb-server mariadb-client

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

systemctl stop mariadb.service
systemctl start mariadb.service
systemctl enable mariadb.service

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
