new pages give 404 error

So i’ve recently set up a lamp server on my raspberryPi. i have wordpress installed and generally up and running. I can access wp-admin and the homepage from my localhost.
The problem is, whenever I add a page, I get a 404 error. Here’s what I’ve done:

-Found out there was not ‘.htaccess’ file. I created it in my blogs root directory.
-Went through and changed server type to apache in vars.php file (broke things, changed it back)
-Went into phpMyAdmin and looked at my wordpress database. I find the the guid of the page entries do not match the url generated by posting the page. Even entering these guids gives me a 404 error.

Any ideas as to what might be going wrong here, or where i could start debugging?
