Requirements

  • Centos 7 must be installed and up to date

Add MariaDB repo

First of all we will add MariaDb repo

[mariadb]

baseurl = http://yum.mariadb.org/10.0/centos7-amd64

Install MariaDB 10 on CentOS 7

Now we will install MariaDB. You need to execute the following command and it will install MariaDB 10 with required dependencies.

yum -y install MariaDB-server MariaDB-client

Start and Enable the MariaDB Services

We will use systemctl to start and enable MariaDB Services.

systemctl enable mariadb.service
systemctl start mariadb.service

MariaDB Secure Installation

It is highly recommended to run the mariadb (mysql) secure installation script before using the MariaDB database.

# mysql_secure_installation

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!

Login into MariaDB

Now we can login and start using the MariaDB.

# mysql -u root -p
Enter password:
