This month’s PC Pro magazine includes something special for fans of the Raspberry Pi microcomputer: full instructions on how to turn the compact ARM-based system into a fully-functional webserver running Apache and the popular WordPress blogging platform.
Based on a chapter of my book, the Raspberry Pi User Guide, the step-by-step tutorial assumes no prior knowledge of Linux or running a server and requires only that you use the Raspbian operating system – which is recommended by the Raspberry Pi Foundation – or another Debian-based distribution, up to and including Debian itself.
When working on the feature for the book, I was actually surprised with how well Apache – software normally found running on multi-core servers with scads of RAM – ran on the 700MHz, single-core ARM-based system with just 256MB of RAM. While WordPress does slow things down a bit, it’s surprisingly usable – and if you’re lucky enough to have one of the Revision 2 boards, which feature 512MB of memory to the original’s 256MB, the whole thing works pretty well.
For more advanced users, one piece of advice not mentioned in the book or magazine feature is to try out an alternative web server package. While Apache is fully-featured and well-supported, it can be resource intensive – something to avoid on an embedded system. Nginx, by contrast, requires significantly less memory and processing power and can give a Pi web server a much-needed boost. Another trick is to enable Turbo Mode, which overclocks the Pi’s CPU, to increase performance still further – although be careful running at speeds above 900MHz, as SD card corruption is a common occurrence.
