A Raspberry Pi is small kit computer that uses an ARM processor. (like those found on smartphones) It has everything one needs to run a webserver, as well as countless other computer projects that are well documented by passionate techies across the web. It is a very bare bones machine, so it forces users to really learn the basics of computers, operating systems, and electronics.
Here is a rundown of the specs:
512 MB RAM
2 USB ports
micro USB port(power supply)
composite video jack
SD card slot
As you can see there isn't much, and one has to supply all the peripherals in order to turn this into a working system. These include a keyboard, mouse, power supply, audio and video cables, TV/Monitor, speakers, SD card(4 Gig), and a ethernet cables or wireless USB dongle.
For this project, the keyboard, mouse and TV/Monitor were only necessary for the initial installation and setup of the system. After that the webserver runs "headless", that is to say without any input or output peripherals. Getting a website up and running is no small task, especially when you are starting from scratch and know little about computer networking. Luckily there is a plether of information, tutorials, and walkthroughs available on the web that I resourced in order to get my feet wet.
Here are some of the best walkthroughs and tutorials I have used, and in many cases still use, to help me better understand computers, Linux operating systems, web design, and networking:
theurbanpenguin.com--Clear, precise youtube
tutorials, and blog that takes you step by step through learning Linux administration.
Terminus--A fun text adventure that helps you use and remember Linux commands. A great way to get comfortable with the command line.
penguintutor.com --I used this site's walkthrough for setting up this webserver.
jeremymorgan.com--This site was also great for setting up the server.
mattwilcox.net--One more Raspi webserver walkthrough.
Current setup: Model B Raspberry Pi running Raspian "Wheezy" with Apache 2.0 (LAMP), most development is done via SSH(Secure Shell) on my Toshiba NB205-210 running BunsenLabs Linux (a minimalist Debian distro)- other tools used include the Geany and nano text editors, FileZilla / WinSCP for file transfers(SFTP), ...
