At the MySQL shell, type the following commands. Remember to use your own, valid values for the database name, and database user, and also use a secure and robust password as the database user password:

> CREATE DATABASE wordpress_database;

> CREATE USER 'wpdb_user'@'%' IDENTIFIED WITH mysql_native_password BY 'password';

> GRANT ALL ON wordpress_database.* TO 'wpdb_user'@'%';

> FLUSH PRIVILEGES;

> EXIT;
