I want to get some hands on knowledge with linux servers (sine the last internship I applied for, required some experience with linux servers, but I had none), and I'm wondering if the RPi would give me the same server experience as any other computer (x86 or ARM). Everyone I've asked about "starting with servers" says to just use any old computer. The truth is. All I have is my laptop with Win7, and an RPi.
I want something that will give me real world experience with setting up a LAMP server, FreeNAS, some kind of media server, or anything else. I'm second guessing myself, because this runs on ARM, and most Linux OS's won't run on arm. I believe Ubuntu and CentOS (from what I heard) are the biggest name servers OS's. I also heard that archlinux runs on arm.
I know the above is a mess of questions, but any help and/or guidance is appreciated.
Can I get cmd line, server setup, and server maintenance experience from the RPi comparable to that of someone that works on x86 machines?
