I spent over 5 hours yesterday trying to figure out whats wrong with my setup. In the ci213/application/controllers and views directories I have a simple site.php controller and test.php view. I'm out of ideas as to why this site wont load. Anyone have suggestions on what I could look for next? Maybe logging it's working properly? If I could get better log errors I could have more to work with.
I figured it has to be something with codeigniter since I have an index.php and index.html at apaches root (/var/www) and also an index2.php at the sites root (/var/www/vhosts/srp-local/htdocs), when I go to localhost/index.(php|html) or srp-local/index2.php the pages load and display properly so php and apache are working.
Trying to load the site I get a blank page so I figured it has to be something with CI. I'm tailing all the log files and the only one that gets an update is the site access.log with the following error.
127.0.0.1 - - [23/Mar/2013:09:00:28 -0600] "GET / HTTP/1.1" 500 381 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0"

I finally found something that pointed me in the right direction. These two posts mentioned how CI uses the @ in the database module might be causing that issue.
php return 500 error but no error log
CodeIgniter project loads blank webpage
I disabled auto-loading the database module and the site works. Now I just have to figure out the database error I was getting that might be causing CI to fail. I'll update this answer once I figure it out.
Update: I checked the account/password and access for the database everything was working. The issue was the php mysql driver was not installed. This is my first time really using an Ubuntu system and I thought that the mysql driver would be installed with the default php package, which I was incorrect about.
After installing php5-mysqlnd and enabling the database library in CI's autoload everything works properly now. The fact that I was not getting any errors is really making me consider changing frameworks.
