How to Install MariaDB 10 on RHEL 8

MariaDB is a popular alternative to the MySQL database management system. It is developed by the original MySQL developers and is meant to remain open source.

MariaDB is fast and reliable, supports different storage engines and has plugins which makes it perfect for wide range of use cases.

In this tutorial we are going to show you how to install MariaDB server on your RHEL 8. We will be installing MariaDB 10.3.10 version.

Note: This tutorial presumes that you have an active RHEL 8 subscription and that you have root access to your RHEL system. Alternatively you can use a privileged user and run the commands with sudo.

Installing MariaDB Server

To install the MariaDB server, we will use the following yum command to complete the installation.

# yum install mariadb-server

This will install the MariaDB server and all the required dependencies.

Once the installation is complete, you can start the MariaDB service with:

# systemctl start mariadb

If you want to have the MariaDB service started automatically after each system boot, you can run the following command:

# systemctl enable mariadb

Verify the status of the MariaDB service with:

# systemctl status mariadb

Secure MariaDB Installation

Now that we have our service started, it is time to improve its security. We will setup root password, disable remote root login, remove test database and anonymous user. Finally we will reload all privileges.

For that purpose, simply run the following command and answer the questions accordingly:

# mysql_secure_installation

Note that the root user’s password is empty, so if you want to change it, simply press “enter”, when prompted for the current password. The rest you can follow the steps and answers on the image below:

Access the MariaDB Server

Let’s go a little deeper and create a database, user and give privileges to that user over the database. To access the server with console, you can use the following command:

# mysql -u root -p 

When prompted, enter the root password that you set earlier.

Now let’s create our database. For that purpose at the MariaDB prompt, run the following command:

MariaDB [(none)]> CREATE DATABASE tecmint; 

This will create new database named tecmint. Instead of accessing that database with our root user, we will create separate database user, that will have privileges to that database only.

We will create our new user called tecmint_user and grant it privileges on the tecmint database, with the following command:

MariaDB [(none)]> GRANT ALL ON tecmint.* TO [email protected] IDENTIFIED BY 'securePassowrd';

When creating your own user, make sure to replace “securePassword” with the password you wish to give to that user.

When you have finished with the above commands, type “quit” at the prompt to exit MariaDB:

MariaDB [(none)]> quit;
Create Database in MariaDB
Create Database in MariaDB

Now you can use the new user to access the tecmint database.

# mysql -u tecmint_user -p 

When prompted enter the password for that user. To change the used database, you can use the following at the MariaDB prompt:

MariaDB [(none)]> use tecmint;

This will change the current database to tecmint.

Alternatively, you can issue the mysql command by specifying the database name as well as shown.

# mysql -u tecmint_user -p tecmint

That way when you enter the user’s password, you will directly be using the tecmint database.
