2. CREATE THE DRUPAL DATABASE

These instructions are for MySQL. If you are using another database,
check the database documentation. In the following examples,
"dba_user" is an example MySQL user which has the CREATE and GRANT
privileges. You will need to use the appropriate user name for your
system.

First, you must create a new database for your Drupal site:

$ mysqladmin -u dba_user -p create drupal

MySQL will prompt for the dba_user database password and then create
the initial database files. Next you must login and set the access
database rights:

$ mysql -u dba_user -p

Again, you will be asked for the dba_user database password. At the
MySQL prompt, enter following command:

GRANT ALL PRIVILEGES ON drupal.*
TO nobody@localhost IDENTIFIED BY 'password';

where

'drupal' is the name of your database
'nobody@localhost' is the userid of your webserver MySQL account
'password' is the password required to log in as the MySQL user

If successful, MySQL will reply with

Query OK, 0 rows affected

to activate the new permissions you must enter the command

flush privileges;

and then enter '\q' to exit MySQL.

3. LOAD THE DRUPAL DATABASE SCHEME

Once you have a database, you must load the required tables:

$ mysql -u nobody -p drupal < database/database.mysql

I just don't get that. Also im doing this for a school. Any help would be appreciated.
