Raspberry pi cluster

As soon as I heard about "Cluster programming" I pretty much knew I had to try it. Now I don't know about you guys but I don't have a serverpark laying around on which I can practice. So naturally I resorted to simpler measures. Which for me were some laptops and pc's tied together in a less than ideal environment.

While talking about the cluster with friends one of them mentioned he saw someone build a cluster of Raspberry pi's on the internet. And sure enough, after a quick google something came up. I expected to find an in-depth tutorial about clustering pi's together. Sadly thats not what I found, and so I decided to blog about it. If I were to go through the struggle I could at least prevent some of you from going through the same struggle.

The pi cluster has been operational since september 2014 and is still going strong today.
The blogs below are all related to the Raspberry pi cluster.

Raspberry pi cluster step 5: Expanding the cluster

In today's post we'll have a look at expanding the cluster with more nodes! We will have a look at how to clone them and how we can set up a universal login using ssh keys.


Raspberry pi cluster Step 4: Setting up the master node

After installing raspbian to the sd card it's time to plug in that SD card and fire up the Raspberry pi. If everything went well you should end up with a screen similar to mine:


Raspberry pi cluster Step 3: Installing the OS

Installing an OS for a Raspberry pi is quite different from installing an OS on any other computer. We will have to write an "image" to the SD card rather than actually "installing" anything. Don't worry if you're confused just now, even I don't know what I'm rambling on about at times!


Raspberry pi cluster Step 2: Assembling the hardware

So today I finally received the required parts to finish up my Raspberry pi cluster and I was extremely excited! To share this excitement with you lot here's a picture of all the parts I'll be using:


Raspberry pi cluster Step 1: Shopping

Well, a raspberry pi is a small $35 dollar Linux computer with an SD card as a hard drive and an USB cable as it's power source. While they are only $35, they perform really well!
