How to Install MariaDB/MySQL on CentOS 7

In this guide we’ll go through the steps for installing the latest version of MariaDB on CentOS 7.

All Commands – without sudo

yum update -y
echo -e "[mariadb]\nname=MariaDB Repository\nbaseurl=http://yum.mariadb.org/10.3/centos7-amd64\ngpgcheck=1\ngpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB" | tee /etc/yum.repos.d/MariaDB.repo
yum install mariadb-server mariadb-client -y
systemctl start mariadb 
systemctl enable mariadb
mysql_secure_installation

All Commands – with sudo

sudo yum update -y
sudo yum install mariadb-server mariadb-client -y
echo -e "[mariadb]\nname=MariaDB Repository\nbaseurl=http://yum.mariadb.org/10.3/centos7-amd64\ngpgcheck=1\ngpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB" | sudo tee /etc/yum.repos.d/MariaDB.repo 
sudo systemctl start mariadb 
sudo systemctl enable mariadb
sudo mysql_secure_installation

 

MariaDB is the default database management system in CentOS 7 and is a drop-in replacement for MySQL. It is an opensource relational database that uses the Structured Query Language (SQL) to manage its data. 

Prerequisites

  • A CentOS 7 VPS
  • Sudo access

Update Your System

Log in as a sudo user and then update your system.

yum update -y

Install MariaDB

At the time of writing this article, the latest version of MariaDB is version 10.3. If you want a different version of MariaDB, go to the official MariaDB repositories page and generate a repository file for the specific MariaDB version you require.

To enable the MariaDB repository, create a repository file named MariaDB.repo and add the following content in /etc/yum.repos.d/MariaDB.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install the MariaDB server and client packages using yum.

yum install mariadb-server mariadb-client -y

Now that MariaDB has installed successfully, run the following command to start and enable the service.

systemctl start mariadb

systemctl enable mariadb

To prevent unauthorized access to your database and remove some dangerous defaults run the following command.

mysql_secure_installation

You will be prompted with an option to change the MariaDB root password, remove anonymous user accounts, disable root logins outside of localhost, remove test databases and reload privileges. It is recommended that you answer ‘yes’ to these options to secure the database server.

Verify the Installation

Run the following to test to get info about the installation of MariaDB.

mysqladmin -u root -p version

You’ll see an output similar to what shown below,
