Starting with linux
 

Hi all,

I am windows system admin,I am new to Linux please guide me how to startup with Linux for administration

Thank you

Try out some Linux distributions using Virtual Machines or Live DVD/USB boots to verify they work on your machine(s) and then consider installing Linux on systems and getting to know it.

Since you're a Windows sysadmin, then you'll understand the general things which you need to do to service users of computer desktops. Learn the Linux equivalents and experiment, and ask more detailed questions versus a general question such as this one. Sorry, but a general question can only give you a general answer, which is highly dependent on the answering person's perspectives. :)

Welcome to the forums! :)

If you have specific questions, I'd start additional threads for each question, but also try to be more specific with each question. Also helps immensely if you've first tried to determine an answer on your own.

:hattip:

If you're a professional, you need to know one of the enterprise-class distros. On a server it's usual to run Linux without a GUI, so the differences between them are less noticeable.

> SUSE Enterprise Linux is based on the free OpenSUSE
> Red Hat Enterprise Linux has a free version, CentOS
> Debian Stable is popular with many organisations that don't need the paid support that comes with SEL or RHEL.

One word: Bash

Since you're a windows admin I will say this:

If Bash and Powershell got into a boxing match.. we all know how ridiculously one sided it would be..

Bash is like glue that can control every single available linux application from the cli. For admin and server work, it is better than any way I can think of to describe it.

Starting with Linux
 

For starters I would suggest just installing Linux on your personal computer with several user accounts. By default, you are the sysadmin for this machine. Try doing a variety of things that require sysadmin privileges like creating user accounts with varying privileges, setting up a way to ftp files to another computer, sharing privileges on specific directories, setting up and managing a webserver, installing a relational database such as MySQL, etc. You can learn a lot just getting those things mastered. Most people who install linux on their personal computers end up learning how to do these things even when they have no intention of managing a larger network.

Hi.

Back up everything and jump in. :D Here are some links to links I thought helpful: http://www.linuxquestions.org/questi...0/#post5545942

have fun.

I would agree that you should "start small," and that you should use virtual machines, perhaps hosted on a convenient personal Windows box.

Oracle is the big-guns company behind VirtualBox, a very complete VM system that is absolutely free.

"So, there you have 'Linux.'" It's running in a window on your Windows box, and you can "snapshot" it at any time (and restore from the snapshot). You can do absolutely anything you want to with it ... or, to it ... and, no matter what you do, you won't hurt your Windows environment. You can say, "I wonder what happens if I try this?" ... and actually get away with it. :D

The first thing that you'll need to do is, simply, "to kick the tires." To learn how this very-different operating system "looks and thinks," even as it does many of the same things that Windows does. :)

And I think that I should warn you to expect that you will be "taking a sip from a fire-hose." Not once, but many times. You are moving from a system that is produced by one vendor, and that is tightly controlled by that one vendor, to a system that runs on more than 20 wildly-different hardware platforms. It has a different viewpoint, a different philosophy, and, "it is owned-and-controlled by no one." It does not have "a GUI management-interface for everything."

At first, you'll absolutely feel like someone hit you squarely in the face with a hot cast-iron skillet. :eek: But then, you'll start to see "what all the fuss is about."

And, I'll also say this: this will bring you a much deeper and more thorough understanding of Windows, as well.

Yes, start small don't miss the basic and invest in good solid foundation.

VirtualBox really helps a lot.

I will not argue with anything above, there is a lot of good advice there.
That said, if you have an extra piece of hardware around there is nothing wrong with installing a distro on hardware a few times. My first install was a CDE desktop for monitoring, my second turned into a print server. It is now faster and easier to start with VirtualBox and load in guests, but there will be a day you want to go beyond.

I would also pick up a cheap copy of the Linux Bible. It does not matter if it is a couple of years our of date, you are seeking the general information about things System Admins (SA) do and have always done and how those look on Linux. Having a paper reference while learning can be very valuable, and these are pretty good. Keep in mind, once you have a good grasp of what we do today, the details will change tomorrow anyway. You will never stop learning and teaching if you are any kind of SA. The book is a good start, Google, vendors, and the systems themselves will turn into your ongoing resources once you are up to speed.

This picture is an interesting representation of the things you can explore with the Linux command line

best advice i can give is buy this O'Reilly book: http://shop.oreilly.com/product/9780596009526.do

... and read it :)

I might be very wrong in all of this, because my time on Linux can be best described as "few and far between" -

Learn the command line.
Learn the Kernel
Learn regex and how to shell script.
LFS might be a nice place to start.

"How to startup with Linux for administration" same way as "windows system admin" if professionally? :D

New to Linux - suggestions
 

=========================
I agree. I agree. I agree.

Your two best friends in Linux are man & bash.
Man -k [something] will try to list EVERY thing that that [something] pertains to.
... (the [] above are not entered)
If you cannot actually do it in bash (a super steroid form of Microsoft$ batch
(.bat) stuff) it may well be that the binary machine is the limiting factor.
WARNING: bash can be devious at times. But do .. man bash .. and READ. Hope your
reading comprehension is good.

I prefer Slackware. Been using it since mid-1993. But if you need the crutches -- try
one of the others. In my opinion they are Window$ Wanta-Be.

as a starter thing... man bash[enter]/[spacebar]fi[spacebar][enter]
..... will take you to the flow control section. (loop while if do and so forth)
and ... man dir ... will show some directory things and the MSDOS dir command and ls
which is Linux for dir. in Linux use ls. Time will teach you why.
/[thing][enter] to find and then use CTRL-S to proceed to next (if present) match.

Another seldom mentioned thing: the Linux /n (newline) is x0D (linefeed)
whereas Window$ uses x0D0A (linefeed, carriage return) (MAC is x0A - roll eyes)
Notepad don't like that. use WordPad on Window$.
