The MoodleBox plugin for Moodle is an administration tool providing a GUI to some settings and management of a MoodleBox, a Moodle server installed on a Raspberry Pi.
It enables a Moodle administrator to monitor some hardware settings, to set the date of the MoodleBox, to allow restart and shutdown of the MoodleBox and changing Raspberry Pi passwords using a GUI. After the installation in Moodle, some steps are required to complete on the Raspberry Pi (see below).
The plugin is compatible with Moodle 3.6 or later. A Raspberry Pi model 3A+, 3B, 3B+ or 4B is recommended.
- A Raspberry Pi (Model 3A+, 3B, 3B+ or 4B recommended)
- Raspbian installed (or another Linux based distribution)
- Package Incron installed
- Moodle installed (obviously)
The MoodleBox plugin must be installed in the Moodle tree of the MoodleBox, in the tool folder. Once installed, an new option MoodleBox will be available in Moodle, under Site administration > Server in the Administration block.
To complete the installation, you have to create some files in the plugin folder and configure some incron jobs on the MoodleBox.
Create necessary files
This step is not needed anymore for versions 1.10 or later
touch .reboot-server; touch .shutdown-server; touch .set-server-datetime; touch .newpassword; touch .wifisettings chown -R www-data:www-data /var/www/moodle/admin/tool/moodlebox
Install incron package and allow root to run it
sudo apt-get install incron echo root | sudo tee -a /etc/incron.allow
