Have you got an old PC lying around? Have you ever wondered how easy it would be to turn it into a web server, so you can learn about hosting your own web sites instead of renting space on a commercial server?
Back in 2009 I put together a step-by-step document that explains how to do it, using Ubuntu Server 7.10. This is now rather out of date, so I've spent the past few days updating it for Ubuntu Server 11.04 (Natty Narwhal), which is available now ahead of its official launch next month.
If you fancy turning that old machine (or even a virtual machine) into a fully functional web server running Ubuntu Server, Apache, MySQL, PHP, ftp, phpMyAdmin, Webmin, and Webalizer, which you can access from anywhere on your home or office LAN, you can get the complete document for free. Just go to www.the-web-book.com/build-your-own-webserver.html.
