Anthony Bartoli on "Creating MySQL databases on my own server (OS X)"

Try logging into mysql on the command line with the username and password you tried using when setting up WordPress.

Then run: SHOW DATABASES;

If you don't see the database you created for your WordPress installation, the user you logged in with does not have the privileges to access the database you made.

I would recommend setting up phpMyAdmin or adminer to modify privileges. Otherwise, consult the MySQL manual to modify them on the command line.
