5. Make Judge Work

There are two recommended routines to make the judge work. The first is the most recommended but it works in Linux only.

5.1. Create Judge Daemon Through Cron

(Linux only)

Setup moodle’s cron job to be called by php cli. In crontab, put a command which is similar with:

php -q /PATH/TO/MOODLE/admin/cron.php

That’s all! Read http://docs.moodle.org/en/Cron for detail about how to setup moodle cron job triggered by php cli (Not wget, curl and etc.).

If it works, a judge daemon would be created. Use

ps -FC php

to ensure the daemon is running.

5.2. Create Judge Daemon in Command Line

If you can NOT trigger cron through php cli or are using Windows, then use this method.

In Linux

Run the following command to create judge daemon:

sudo -u APACHE-USER php /PATH/TO/MOODLE/mod/assignment/type/onlinejudge/judged.php

The APACHE-USER means the username of apache in your system. It is www-data in debian, apache in fedora. Perhaps `ps aux|grep apache` or `ps aux|grep httpd` can help you getting the correct username.

Use

ps -FC php
