A few weeks back it was my birthday. I never now what to ask that is cheap enough for most people. But this time i thought of the Raspberry PI Zero W. It's cheap, it's flexible, it's great. It even builds a wall for you. Multiple people bought one for me, and that's how i ended up with 3 identical RPI's.
I wanted to try out Ansible for a long time, and 3 Raspberry PI's is a perfect use case for this. I have created a Ansible Playbook to install a LEMP server: Linux (duh), Nginx, Mysql and PHP (7.1). The code is freely available on Github so you can use it too. You can find it here:
