For those of you who didn’t know, MariaDB is a drop-in replacement for MySQL. It is easy to install, offers many speed and performance improvements, and is easy to integrate into most MySQL deployments. MariaDB is widely used and several Linux distributions and large companies have already switched from MySQL to MariaDB.
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 through the step by step installation MariaDB on CentOS 7.
Install MariaDB on CentOS 7

Navigate to /etc/yum.repos.d/ on your CentOS box and create a new file called MariaDB repo:
Step 2. Install MariaDB using Yum.

Step 3. Configuring MariaDB.
The configuration files and binaries for MariaDB are mostly the same as MySQL. For example, both use a configuration file called my.cnf.
Step 4. Secure MariaDB after installation to.
By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

password for the root user. If you'vejustinstalledMariaDB,and
youhaven't set the root password yet, the password will be blank,

Reloading privilege tables..
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
Remove anonymous users? [Y/n] y
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
