I recently decided to consolidate all of my random projects into a single hosting account as it was starting to get very expensive to run each on an individual hosting plan. I purchased the HostGator Baby plan which allows hosting of multiple domains.

You have to set it up with a root domain name which is fine (I used my portfolio domain name). As far as file structure, I wanted a folder for each site in /public_html so the structure looks like this:

- public_html/
   - myportfolio.com/
      - ... my files ...
   - anothersite.com/
      - ... my files ...
   - thirdsite.com/
      - ... my files ...

I setup add-on domains and pointed them to their respective folders which works fine. My problem is the root domain ex. myportfolio.com expects it's files to be contained at the root of /public_html rather than within it's folder I created. I setup a redirect to point requests for myportfolio.com to myportfolio.com/myportfolio.com/ which works initially except (at least in my WordPress installation) it still references it's root folder as public_html.

TL;DR; What is the best way to go about setting up multiple site hosting in a shared hosting environment (i.e. I can't setup vhosts). Does anybody know of any tutorials or videos that walk through this more clearly? Thanks.
