Configure MariaDB 10.x on CentOS 7

1. Start and enable the mariadb database service on boot.

systemctl enable mariadb && systemctl start mariadb && systemctl status mariadb

# systemctl enable mariadb && systemctl start mariadb && systemctl status mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

2. Client version checking with command:

# mariadb -V
mariadb  Ver 15.1 Distrib 10.8.5-MariaDB, for Linux (x86_64) using readline 5.1

3. Use the mariadb-secure-installation script to secure your MariaDB database server

sudo mariadb-secure-installation

# sudo mariadb-secure-installation

You already have your root account protected, so you can safely answer 'n'.

Change the 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!

4. Access to MariaDB shell using the password that you’ve created in the previous step.

# mysql -u root -p
Enter password:
