This guide has been written to help you install and configure the MariaDB Database server on RHEL 8. RHEL 8 is distributed with MariaDB 10.3 which is binary-compatible with MySQL. MariaDB 10.3 is a multi-user, multi-threaded SQL database server. You can find all RHEL 8 new features on my previous article Red Hat Enterprise Linux 8 (RHEL 8) New Features & Review

MariaDB is a community-developed fork of the MySQL relational database management system. it is a fast and robust database server with a huge community behind its development and improvements.

  • FOR loops
  • MariaDB Galera Cluster, a synchronous multi-master cluster, is now a standard part of MariaDB.
  • Sequences
  • Instant ADD COLUMN for InnoDB
  • Invisible columns

Summary     : The MariaDB server and related files
Description :
MariaDB is a multi-user, multi-threaded SQL database server. It is a
client/server implementation consisting of a server daemon (mysqld)
and many different client programs and libraries. This package contains
the MariaDB server and some accompanying files and directories.
MariaDB is a community developed branch of MySQL.

Step 3: Start and Configure MariaDB on RHEL 8

Activate the mariadb service using the command below:

sudo systemctl enable --now php-fpm

Once the service is started, run the command mysql_secure_installation to harden MariaDB database server security.

$ 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: <ENTER NEW PASSWORD>
Re-enter new password: <CONFIRM 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!

Ensure you:

  • Set Database root user password
  • Remove anonymous users
  • Disallow root user remote logins
  • Remove test database and access to it

When done, test access using the root user

$ mysql -u root -p
Enter password:
