If you can access phpMyAdmin and cPanel, you can do the following:
- From phpMyAdmin: Create a database
- From cPanel - MySQL Databases: Create a MySQL user
- From cPanel - MySQL Databases: Add that MySQL user to the new database
- Add the database name, user name, and user password to the wp-config file. Just be sure to add the hosting account prefix.
- DB host is probably: localhost
The bottomline: if you're not doing a one-click install you need to create the following:
- database
- user
- password
