“Database Connection Error” upon install in Apache VirtualHost document root

I have apache virtualhosts up and confirmed working. I want to install wordpress for one of the vhosts, so I unpacked all the wordpress files in the document root for that vhost. I proceeded to follow the WordPress installation instructions. Now I am getting a database connection error upon going to to the install.php. I created the DB and WordPress user from phpMyAdmin.Here is my wp-config.php:

<?php

So I am new to MySql but I did troubleshoot as much as I could. I used SET to make a new passwd for my WordPress DB user. Still no dice. I confirmed mysql is running. I double checked passwords and spelling. I tried to login to mysql using the WordPress DB user, but I got:

ERROR 1045 (28000): Access denied for user ‘l********e’@’localhost’ (using password: YES)

I think this may be because my WordPress DB user has no global privileges, but I honestly do not know since today is basically my first day using mysql ever.

The only thing I can think of is that ‘localhost’ isn’t the correct DB hostname due to apache vhosts, but everyone says it should still be. Oh and its worth noting that in phpMyAdmin, my WordPress user’s “host” in user overview was ‘%’ until I changed it to ‘localhost'(I tried setting the wp-config.php DB host to ‘%’ before changing.
