Create a new MariaDB database and user

These are the basic steps to create a new database and user for your applications:

Create a new database:

MariaDB> create database DATABASE_NAME;
Query OK, 1 row affected (0.00 sec)

Create a new user (only with local access) and grant privileges to this user on the new database:

MariaDB> grant all privileges on DATABASE_NAME.* TO 'USER_NAME'@'localhost' identified by 'PASSWORD';
Query OK, 1 row affected (0.00 sec)

Create a new user (with remote access) and grant privileges to this user on the new database:

MariaDB> grant all privileges on DATABASE_NAME.* TO 'USER_NAME'@'%' identified by 'PASSWORD';
Query OK, 1 row affected (0.00 sec)

After modifying the MariaDB grant tables, execute the following command in order to apply the changes:
```
MariaDB> flush privileges;
Query OK, 1 row affected (0.00 sec)
```
