I am absolutely shocked at how much is taking place within this company that I have little to no experience with. To help bolster my experience, I purchased a used server to use for hands-on training and practice. My ultimate goal is to have a complete, secure LAMP server available to the public running CentOS. I have been browsing the Net for various guides and tips on setup, optimization, security, and maintenance, but nothing I've found really gives me a hands-on approach to the topics I want to learn about. When you all started out, what route did you take to pick up the server setup and maintenance skills you have now? Is there anything in particular that you would recommend to someone who has excellent skills with consumer PCs and servers but is a total newbie to corporate and enterprise networking and servers?"
