So it’s all well and good having a nice MySQL cluster running on some tiny hardware, but what can you do with it?

Well in order to demo the software at some upcoming techtours my colleague put together a little Java application to showcase what can be done.

I want to run my raspberry pi’s headless so in order to get this to work I needed to install a vncserver

sudo apt-get install tightvncserver

Once this is installed make a note of the display you set up and check you can connect to it via a vnc client.

Install the java application

configure the config file for the MySQL credentials

Run the java application in a shell window on the remote VNC session making sure the screen variable has been set accordingly

export DISPLAY=1:4

When you have it all working it should look like the following
