I have already written articles showing how to set up the Raspberry PI and how to set up a personal web server on the Raspberry PI.

I was recently asked whether I could expand further and show how to install WordPress onto the web server.

To be able to follow this guide you will need to have set up your Raspberry PI and you will need to have PHP, MySQL, PHPMyAdmin and a web server such as Lighttpd or Apache installed. Follow the guide for setting up the personal web server linked above if you haven’t already.
