Google is your friend. There are similar threads on LQ. Look into them.
And "Server" forum is not for your question of course.
I'll make it brief since you have no idea how to search for an answer.
1. Do not use windowz(that icon completely gives you away). Use Linux. use it everyday. use it as your working environment as much as possible.
2. Read manuals. Try what is written in manuals. Follow the advices from there. They were written by people knowing what they are doing, trust them. That works 100% for all basic Linux utils(coreutils). Whenever you got trouble: read on-line documentation. Read forums. It never hurts even without any trouble. If you can't find something on the manual, ask it. Be sure to read and understand this document
before you ask for any help.
3. Learn the Linux basics. Work with standard tools. Pay an attention to manuals at this point.
4. Go up with configuring services. Try to install different servers and configure them. Check they are working as expected from another computer(assuming you have one more computer and you've configured the network).
5. Try something yourself. Do something just for fun. Play with a system. If something goes wrong, search for an answer(see #2).
6. Try coding a shell scripts. Say, code up a script that parses output of example.org from curl and extracts that link to RFC.
7(optional). Do some coding on a preferred language to do the same task. Make tasks for yourself. Solve them.
And remember one more thing about that RHCE: say, if I would be searching for a guy knowing linux environment I will not look if he has any certification or not. I will look on what he can actually do. Activity in web communities/opensource development is most welcome by me.
In most cases RHCE won't really help you to get a job unless you really KNOW linux. So in case you have RHCE but actually don't know linux that job will be more of problem for you, rather than of money or enjoyment.
