I've occasionally wondered if it was at all practical to run a small functional Moodle site using just a Raspberry Pi and whenever I've been half tempted to try I've came to the swift conclusion that the answer was most likely 'No'; and I think this is still probably the case today. We are now however in the brave new era of the Raspberry Pi 2 where we have more cpus and RAM to play with, and after my friend Moodle Fairy asked if it was at all possible or indeed worthwhile to do such a thing I decided it was time to give it a real shot and put to task my experience in optimising Moodle at work hosting a Moodle site on the decidedly lightweight Pi 2. So what is the answer? Can you run a useful Moodle on a raspberry Pi 2? Well, yes you can! And not only that I have been rather impressed with the sites overall performance which has exceed all reasonable expectations. Your average page load time is well under a second.
