Moodle Tech Tip – Cron

The Moodle Cron process is a PHP script that must be run regularly in the background as it runs various tasks at differently scheduled intervals.

Cron is vital to the operation of a Moodle site and triggers many things including, but not limited to:

  • Forum posts digests
  • Email processing
  • Notifications – including the all important Assignment submissions
  • Course Backups
  • Emptying the Recycle Bin
  • Processing enrolments and unenrolments
  • Synchronising users (e.g. from external sources)
  • … and MANY other things !

An administrator can see and schedule cron tasks very precisely from:

Administration > Site administration > Server > Scheduled tasks

(see Scheduled tasks)

If you are a Moodle administrator you should definitely read the main Moodle Docs:

https://docs.moodle.org/33/en/Cron

If you are not from a linux background, it’s really worth doing a little background reading about Cron too.

If you are hosting on Ubuntu/Debian then the distribution guides are pretty good:

A quick search on the net will also turn up plenty of generic guides such as this tutorial:
