MariaDB is an open-source database server which is created & developed by Michael ‘Monty’ Widenius (creator of MySQL). We can also say MariaDB is a drop-in replacement to MySQL Server and is compatible with MySQL database.

In this post, we will discuss how to install & connect MariaDB in CentOS 7

By default MariaDB packages are not listed in CentOS repositories, so to install this first we have to enable MariaDB repositories.

Setting up MariaDB Repositories

Create a file /etc/yum.repos.d/MariaDB.repo with below content:

# MariaDB 10.0 CentOS repository list - created 2014-10-23 13:06 UTC
name = MariaDB
baseurl =

Install MariaDB

Open the terminal and type below yum command.

# yum install MariaDB-server MariaDB-client

while Installing we can get below conflicting error:

Transaction check error:
 file /etc/my.cnf from install of MariaDB-common-10.0.14-1.el7.centos.x86_64 conflicts with file from package mariadb-libs-1:5.5.35-3.el7.x86_64
file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-10.0.14-1.el7.centos.x86_64 conflicts with file from package mariadb-libs-1:5.5.35-3.el7.x86_64

So to resolve this problem remove postfix & mariadb-libs:

# yum remove postfix mariadb-libs-5.5.35-3.el7.x86_64

Now Again re-run the above yum command to install MariaDB Server.

Starting MariaDB Service

# systemctl start mysql.service

Now Set MariaDB root password:

# mysql_secure_installation 


In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorization.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success! 
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
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!

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
 ... Success!

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...
 ... Success!
 - Removing privileges on test database...
 ... Success!

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

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
