Cronjob problem

I've done this a few different ways. If security isn't an issue, you can just run

Code:

wget http://mysite.com/cron

You need to consider the possibility of someone typing that URL into their browser - its unlikely you'd want to allow someone to fire your cron manually at a random time of day.

If you have cURL available on the server, you can add a little security by adding a post variable.

Code:

/usr/bin/curl -d "key=F00b4r" http://mysite.com/cron

Then in the cron controller:

Code:

function Cron()
{
    parent::Controller();
    if ($_POST['key'] != 'F00b4r') show_404();
}

I recently worked on a project where I needed a cron to run some data extraction and DB related stuff (about 300-500 queries per min/every min). Just to cut back on any unneeded resources, I ended up stripping a few pieces out of CI's core to use only the libraries I needed.

1. http://nevercraft.net/files/ci_cron/cron...ernal.phps
2. http://nevercraft.net/files/ci_cron/cron...oller.phps
These two files trick CI into working right while stripping away some unneeded stuff. File 1 contains constants about your application, so make sure to set them.

3. http://nevercraft.net/files/ci_cron/cont...n_job.phps
This is a standard controller that contains the code for your cron job. Notice: You extend ControllerStripped, not Controller.

4. http://nevercraft.net/files/ci_cron/cron/cronjob.phps
This is the file that will be called by the cron daemon

Files 1, 2, and 4 go in /root/crons or wherever you want. File 3 would go in application/controllers.

Then you simply call the cron via

Code:

php /root/crons/cronjob.php

You might need to make some changes to make it work the way you need it to, but it should point you in the right direction.
