If you don’t have a GUI interface for your database server – like phpMySQL for example – you can create MySQL/MariaDB users and databases from the command line.
1. Authenticate as the MySQL root/admin user
# mysql -u root -p
2. Create the desired database
mysql> create database DATABASE_NAME3. Allow user access to the MySQL server
mysql> grant usage on *.* to USER_NAME@localhost identified by 'USER_PASSWORD';
4. Grant privileges to the user
mysql> grant all privileges on DATABASE_NAME.* to USER_NAME@localhost;
Example on a test MariaDB server:
[root@web ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 4180008
Server version: 10.3.28-MariaDB MariaDB Server

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