How To Install MariaDB On CentOS 6

Mariadb-CentOS

In this tutorial, we will show you how to install and configuration of MariaDB on your CentOS 6 server. 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 and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MariaDB databases on CentOS 6.

Prerequisites

  • A server running one of the following operating systems: CentOS 6.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MariaDB on CentOS 6

Step 1. First, you need to enable the repository on your system.

Navigate to /etc/yum.repos.d/ on your CentOS box and create a new file called MariaDB repo.

## RHEL/CentOS 6 64-Bit ##

[mariadb]
name = MariaDB 
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

## RHEL/CentOS 6 32-Bit ##

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Step 2. Install MariaDB on CentOS 6.

Installing MariaDB using yum:

yum update
yum install -y MariaDB-server MariaDB-client MariaDB-devel

After the installation is completed, start MariaDB:

service mysql start

Set MariaDB to start on boot:

chkconfig mysql on

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.

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

Step 4. Secure MariaDB after installation too.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

# mysql_secure_installation 
/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): 
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!
[root@idroot]#

Step 5. Login into MariaDB.

Login to MariaDB with the root credential which was set earlier.

mysql  -u root -p
