Using LAMP and CI, I simply made a cron.php controller and created various functions to do whatever operations I needed to run. If your cron is doing database manipulation, I would suggest making those functions in a model and calling them from your cron.php controller. This way you can take advantage of all of CI's features instead of a from scratch file. After making your functions, just run
Code:
wget http://www.example.com/cron/method
