In this article we explain how one can install and use MariaDB 10.4 on RHEL 6 / CentOS 6. MariaDB is an open source relational database which provides an SQL interface for accessing data. The latest versions of MariaDB include support for GIS and JSON. MariaDB is a fork of MySQL database, with its active development under open source community.

MariaDB latest packages are not available in Red Hat or CentOS provided RPM repositories. We’ll have to add MariaDB provided repository then install the packages from there. I believe you can also use Software Collections repository, but I didn’t try using it.

Add MariaDB 10.4 repository to RHEL 6 / CentOS 6

Let’s add MariaDB 10.4 YUM repository to our RHEL 6 / CentOS 6 system:

CentOS 6:

sudo tee /etc/yum.repos.d/mariadb.repo<<EOF
name = MariaDB
baseurl =


sudo tee /etc/yum.repos.d/mariadb.repo<<EOF
name = MariaDB
baseurl =

Once the repository is added update package cache index to confirm it is working.

sudo yum clean all
sudo yum makecache

List available repositories:

$ sudo yum repolist

RHEL 6 command output:

Install MariaDB 10.4 on RHEL 6 / CentOS 6

With the repository added and confirmed to be working we can begin installation of MariaDB 10.4 on CentOS 6 / RHEL 6 system.

sudo yum install MariaDB-server MariaDB-client

Start the database service.

$ sudo /etc/rc.d/init.d/mysql start
Starting MariaDB.210129 20:57:51 mysqld_safe Logging to '/var/lib/mysql/localhost.localdomain.err'.
210129 20:57:51 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

Enable the database service to be started on system boot.

sudo chkconfig mysql on

The service should be running:

$ sudo service mysql status
 SUCCESS! MariaDB running (3175)

Secure MariaDB Database Server

The final step is to secure our database server installation by setting the root user password, removing test database and anonymous users, and disabling remote root user login.

$ sudo 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 authorisation.

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!

Try authenticating to MariDB shell using the set password for the root user.

$ mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 17
Server version: 10.4.27-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Confirm the version of MariaDB database server we’re running.

MariaDB [(none)]> SELECT VERSION();
| VERSION()       |
| 10.4.27-MariaDB |
1 row in set (0.000 sec)

Exit MariaDB shell:

MariaDB [(none)]> quit

We have successfully installed MariaDB 10.4 on CentOS 6 / RHEL 6, started the service and secure the database server.
