Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 39
Server version: 10.11.3-MariaDB-1 Debian 12

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

Step 4 – Start To Use MariaDB Server

Now we want to show you a basic usage of MariaDB on Debian 12 by creating a database and user.

Run the following command from your MariaDB console to create a new database:

MariaDB [(none)]> CREATE DATABASE orca_database;

Here you can create a new user and give them full privileges on the database you have just created.

Run the following command to create the user and replace the password with a secure password of your own:

MariaDB [(none)]> GRANT ALL ON orca_database.* TO 'olivia_user'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

Now you need to be sure that they are saved and available in the current session. Flush the privileges with the following command:

MariaDB [(none)]> FLUSH PRIVILEGES;

Then verify that the user has access to the orca_database database with the following command:

MariaDB [(none)]> SHOW DATABASES;

In your output, you will see:

Output
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| orca_database      |
| performance_schema |
| sys                |
+--------------------+
5 rows in set (0.003 sec)

Now you can exit from your MariaDB shell by using the command below:

MariaDB [(none)]> EXIT;
