Step 1: Add MariaDB Yum Repositories

First add MariaDB yum repository in our system. Create a new repo file /etc/yum.repos.d/mariadb.repo in your system and add below code as per your operating system and architecture.

For CentOS/RHEL-6 64 Bit

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/rhel6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

For CentOS/RHEL-6 32 Bit

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/rhel6-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

For CentOS/RHEL-5 64 Bit

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/rhel5-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

For CentOS/RHEL-5 32 Bit

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/rhel5-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

For Fedora 19/18/17 – 32 Bit

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/fedora19-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Step 2: Install MariaDB

Let’s use following command to install MariaDB 10.0 in your system. This will also installed other dependencies automatically.

# yum install MariaDB-server MariaDB-client

After installing MariaDB in your system, lets start service using following command.

# service mysql start

Step 3: Secure MariaDB Install

Finally we need to secure our MariaDB install with passwords and do some other changes. To do this run secure installation script from command line.

# mysql_secure_installation

Secure installation script will ask for user input as some points, follow the installation as per below output showing, All user inputs are highlighted with red color.

/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

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): [Press Enter]
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: [Enter Password Here]
Re-enter new password: [Re-enter Password Here]
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!

Step 4: Verify Connection

After installing and completing configuration, connect to mariadb server using following command

# mysql -u root -p

Enter password:
