Install MariaDB 10.0 on CentOS linux using YUM command

MariaDB 10.0 is the development version of MariaDB. It is built on the MariaDB 5.5 series with backported features from MySQL 5.6 and entirely new features not found anywhere else.
For CentOS, RedHat, and Fedora, it is highly recommended to install from a repository using YUM. This page walks you through the simple steps.

Adding the MariaDB YUM Repository

We highly recommended to use custom MariaDB YUM repository to install. Create a repo file under/etc/yum.repos.d/MariaDB.repo, Copy and paste following line under MariaDB repository:

Add repository on Centos 6.5 32-bit

# vi /etc/yum.repos.d/MariaDB.repo

and paste following line:

# MariaDB 10.0 CentOS repository list - created 2014-03-12 12:46 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Add repository on Centos 6.5 64-bit

# vi /etc/yum.repos.d/MariaDB.repo

and paste following line:

# MariaDB 10.0 CentOS repository list - created 2014-03-12 12:47 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
Add MariaDB 10 repository on CentOS 6.4 -32-bit
Add MariaDB 10.0 repository on CentOS 6.4 -32-bit

The example file above includes a gpgkey line to automatically fetch the GPG key we use to sign the repositories. This key enables yum and rpm to verify the integrity of the packages it downloads.

Installing MariaDB 10.0 with YUM

With the repo file in place you can now install MariaDB like so:

# yum install MariaDB-server MariaDB-client -y

Starting MariaDB

After complite installation process, start MariaDB width following command:

# service mysql start

or

# /etc/init.d/mysql start

Set MariaDB to start on boot:

# chkconfig mysql on

Secure MariaDB after installation

  • Set (Change) root password
  • Remove anonymous users
  • Disallow root login remotely
  • Remove test database and access to it
  • Reload privilege tables

To secure MariaDB installation enter following command:

#  mysql_secure_installation

Example output:

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: ENTER YOUR PASSWORD
Re-enter new password: REPEAT YOUR 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!

Restart MariaDB:

# service mysql restart

Try to connect to MariaDB:

# mysql -u root -p
Connect to MariaDB 10.0
