To Do’ s after the fresh installation of MariaDB and to harden the security of MariaDB
This step consist of options to set root password, removing anonymous users, disallowing remote root login, remove the test database and secure access to MariaDB.

[root@linuxhelp Desktop]# 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!

To restart MariaDB

By restarting the service, the settings done in the above step takes effect on MariaDB database

On RHEL/CentOS 6

[root@linuxhelp Desktop]# /etc/init.d/mysql restart
Shutting down MySQL. SUCCESS! 
Starting MySQL.. SUCCESS!

Now we have completed post installation procedures, let we try logging in now

Initially we just entered “ mysql” to log into MariaDB but after setting password,if we run the same command we get an error on permission issues. So use the below command which asks to enter the password of root user.

[root@linuxhelp Desktop]# mysql -u root -p
Enter password:
