I am trying to setup open_basedir on the php.ini file on the server however I'm not really sure how.
Do I create a directory somewhere on the server?

You can check the current status in Joomla! Administrator, under Site - System Information - PHP Information (example from 2.5)
Find your php.ini file (search for php.ini in the PHP Information page, it should be under Loaded Configuration File), make a backup and then add the following line (adapted to your current needs; don't forget to remove the comment sign ; before open_basedir):
open_basedir = /home/users/you/public_html
Restart your web server (probably Apache).
Now in Joomla! you should see the a value for open_basedir.
Make sure you test your Joomla! installation by trying some basic tasks, including updating an extension or installing a new one.
