I bought a Raspberry Pi this week and used it to replace the server this blog is hosted on. There are plenty of guides to installing WordPress on the Pi but I was pleasantly surprised to find that none of them were necessary and the whole process took only a few hours.
I even managed to get Ampache up and running with little effort. Tomorrow I will add NodeJS and MongoDB and see how they run.
It is not as fast as the last server but the switch from a 250w power supply to the 3.5w that the Raspberry Pi consumes makes the whole effort worthwhile. I have overclocked the Pi, switched on Quick-Cache in WordPress and now I’m happy with the results.
