Windows guy has to learn RHEL now
OK, I've been a Windows administrator for a LONG time, but I just got a bunch of RHEL 5 servers thrown in my lap. Me being able to properly spell Linux is the extent of my Linux knowledge unfortunately. Anyone have some ideas on what I should read to quickly get myself up to speed and to be able to support them? Right now I can log into the servers, and that's about it.
Many thanks! |
Hi rjo98,
Welcome to Linux Questions! The best way to learn Linux is using it. Good Luck! |
Hi,
Welcome to GNU/Linux! 'Linux Documentation Project' would be a good place to start. The 'Rute Tutorial & Exposition' book covers GNU/LINUX system administration' 'Linux General Help' section has a lot of information. Plus take a gander at 'Slackware-Links'. More than just SlackwareŽ links! |
Generic Windows/DOS to Linux information. You're not installing anything but it has some good conceptual discussion. It is generic not RedHat specific:
http://www.faqs.org/docs/Linux-HOWTO...nux-HOWTO.html Some Linux equivalents of Windows software: http://www.linuxlinks.com/article/20...uivalents.html Some DOS to Linux command euivalents: http://www.novell.com/coolsolutions/trench/16419.html RHEL documents: https://www.redhat.com/docs/manuals/enterprise/#RHEL5 Also remember the "man" command. It lets you read manual pages for almost every command and library. e.g. If you want to do a directory listing the 3rd link above would tell you about "ls" instead of "dir". You could type "man ls" to get more details of ls command. You can also do "man -k <keyword>" to try to see if there is a manual page that includes what you are trying to do. e.g. "man -k route" for questions about routing setup might produce: NETLINK_ROUTE [rtnetlink] (7) - Linux IPv4 routing socket esddsp (1) - attempt to reroute audio device to esd esddsp [esdplay] (1) - attempt to reroute audio device to esd iproute (rpm) - Advanced IP routing and network device configuration tools. mrtg (rpm) - Multi Router Traffic Grapher rdisc (8) - network router discovery daemon route (8) - show / manipulate the IP routing table traceroute (8) - print the route packets trace to network host traceroute (rpm) - Traces the route taken by packets over an IPv4/IPv6 network You could then type "man traceroute" if that appeared to be the one that was closest to what you were hoping to find. man exists on both UNIX and Linux. Linux also has "info" which gives more detail on some things. One key thing to remember is that Linux unlike DOS/Windows is case sensitive. Ls, ls, LS an lS are 4 different things. Most people keep things lower case (and most commands are) so unless someone specifies uppercase it is generally lower case. (e.g. When I say "ls" I mean lower case "ls" as I typed NOT "LS".) P.S. Welcome to the Dark Side! :jawa: |
Thanks!!
Thanks to both of you. I think the DOS/Windows --> Linux ones will probably be most helpful. Like you said, knowing a dir is now a ls is the type of thing that'll easily stick in my memory.
Would you recommend me buying any books also or you think all these websites are the way to go? |
Some people have an easier time reading books than web sites. Also the book is portable so you can read it anywhere.
The downside to computer books is they quickly become obsolete and are generally fairly expensive even for soft copy. Something like this book may help: http://www.amazon.com/gp/product/047...V09ZNGTX18A50F Fedora is a Linux Distribution (a/k/a distro) that is bleeding edge but much of what is in it ends up in RHEL eventually. Fedora has a very short life cycle whereas RHEL has a much longer one. I noted this only because the book discusses both Fedora and RHEL. Also in an earlier version of the book it came with Fedora installation media so this one may as well. The internet is a great resource for all FOSS (Free Open Source Software) including Linux. Don't worry about taking a long time to learn it all. I've been doing UNIX/Linux full time since 1991 and still don't know it "all". You can do quite a bit without books - the main benefit to a book over the internet is that you know it is specific to the subject you are interested in. Internet searches can be difficult to craft to get just that piece of information you want to know. |
Thanks. Sounds like I'll just stick to the websites for now. I'll just read them on my laptop with wireless, portable to a point! haha.
I'm downloading a Fedora 11 DVD ISO now, hopefully that will give me something to play with after I read some of that stuff. But I swear I read something somewhere that the Fedora is all GUI so that wouldn't me with RHEL since that's all command line? |

SS64.com Command line reference explains both Windows and Linux commands in great detail, and with decent examples. GNU Manuals Online has complete manuals for all the great GNU software you're likely to encounter. Don't neglect the documentation already installed on your system. In particular, you should familiarize yourself with the man and info commands. There may also be HTML documents, but I can't say exactly where they will be. On Kubuntu, many program's HTML documentation is installed in /usr/share/doc/programname and /usr/share/programname/doc. |
It is not "all" GUI. It allows for GUI. You can have a desktop (on the console) like you do on Windows (though of course it is not exactly the same).
The real power in Linux is at command line (CLI) but you can do a fair amount in the GUI. The deal is there are different desktop environments such as KDE and GNOME. It is all based on "X-Windows". You can even open a "terminal" in the GUI to get to CLI. |
So sounds like once my DVD download finishes in a few hours, once I get it installed, I need to look for terminal and then I can try to experience Linux! Thanks. Keep your fingers crossed!

If you are not familiar with...
I can think of this one too for a general tutorial, going from basic to advanced, if it on the the whole is not too basic for your needs. http://www.linux.org/lessons/ There are also the many books by o'reilly, some that may prove useful. http://search.oreilly.com/?q=linux |
that linux.org one has a beginner's guide, that looks like a good one after skimming through the first couple pages of it, thanks!

I know you said you were going to stick with Web sites right now.. but I'll throw this out there anyway..
Linux for Windows Administrators.. http://www.amazon.com/s/ref=nb_ss_b?...rators&x=0&y=0 Linux for Windows Administrators (Mark Minasi Windows Administrator Library) Linux for Windows Nt/2000 Administrators: The Secret Decoder Ring (Mark Minasi Windows 2000) Official Red Hat Linux Administrator's Guide by Red Hat Inc Best of luck in your training. |
Oh, that looks like it could be really good! the title is dead on for what I am! time to see if there's a RHEL for Windows administrators too!

However, my immediate suggestion is that you should look through some of the links that have been suggested already (and I'll add one Linux home Networking, on the grounds that getting your head around networking may be one of the things that slows you down most, initially, and their chapter 14 (firewalling) is straight out of Harrison). That will give you enough to look at for the moment, and once you know what is causing you grief, you'll be in a better position to say what else you want to know. A couple of very general tips
I make those two observations, because until you make those observations and realise what flows from them, you won't make an effective administrator. Maybe, you don't have to get there particularly quickly, which would be good. trying to administer a Linux/Unix box as if it was 'a windows box, done badly' (I'm not arguing that's what is is, at all) will just lead to frustration. |
