CentOS = Red Hat Linux.

CentOS is built using the sources from Red Hat Enterprise Linux and is 100%
binary compatible with RHEL.
Red Hat has quite good documentation available on their web site.

One of the first things you will need to do is identify the distribution and
version of Linux in which you will be dealing.  Ubuntu is a growing favorite
for the desktop, Debian is one of the favorites for servers.  The version of
the distribution is also important when looking for tutorials, but not
nearly as much as the distribution.  Most distributions have a website, such
as Uvuntu.org that has fairly good documentation, including reference
manuals and tutorials.  If you read any reference manuals, make sure they
are for the version that you are using.  

 

I think most of the Linux distributions use the bash environment.  There is
plenty of reference style help through commands like 'man' and 'info'.  So
to look up all of the possible options for the 'apt-get' command, type "man
apt-get".  For bash script programming, after looking through the official
documentation mentioned above, I just perform a Google search for something
specific after "ubuntu bash", or whatever environment in which you are
interested.  

 

Don't be sure that you will not be expected to touch Apache.  I would assume
this web server needs security updates at least as often as the SQL database
software.

Jim,

 

I find myself in somewhat the same boat just recently. I have just been
informed that we are switching all our HP/UX environments over to Suse
linux. While I have been asured that I can continue to use Tera Term for my
SSH sessions, I know there are going to be some differences between the KSH
shell I am used to and whatever shell linux is using. So, I will be jumping
into some linux book or books myself shortly. 

 

We use Weblogic instead of Apache but still I need to learn how to manage
the Weblogic environment under linuyx right away. So, while I don't as yet
have any suggestions, I will certainly be following this thread closely.

        Hi,

        On the system I'm using, I don't have the authority to administrate
the operating system, but I do have the authority, and need to, administrate
the other software on the box that doesn't come with it, so I need to come
up to speed yesterday. You know how that is. 

         

        I cracked open the book called Learning The Unix Operating System
Fifth Edition and started using it to learn basic commands. Among other
things, two things are tripping me up. First, I'm using Putty. I have it set
up properly with JAWS, but I'm being driven crazy any time data needs to
scroll the screen because the whole screen is being spoken. 

         

        The second thing has to do with knowing what I need to learn. I'm
just trying to learn what I need to know for now, and branching out from
there. Unfortunately, I'm not sure exactly what all that entales. But
fortunately, I do have some time, because we're just starting to use MySQL
and PHP. 

         

        So I see three big tasks or things to learn. 

         

        * What's involved in administrating Apache, like not letting the
logs get too big, possibly installing a friendly statistics package, or
whatever.

        * Setting up daily backups of the changed MySQL database or
databases that we have.

        * Whatever MySQL administration that I have no earthly idea I may
need to do.

        * I'll have to upgrade MySQL at some point.

        * I'll have to upgrade PHP at some point.

        * I pray that I never have to upgrade Apache.

        * Possibly installing some nice, convenient packages like
PHPMyAdmin. But I'm thinking that like the people who were advocating
learning the dirty way, I think it's best to probably learn how to do it
from command lines so that I have total control and really know what's going
on.

         

        But I'm starting with basic commands, but at the same time, trying
to do my first Drupal installation, and I'm in real trouble because of
course there's this deadline. 

         

        Back to my UNIX book.

         

        Specifically, I didn't see in the book two things. First, what
permissions do files and directories automatically get when you create them?
Second, I used to know a little more about some sort of file in my home
directory that I could put stuff in to customize the environment a little
more. I know that that file has a name that starts with a period. Yet
another thing. I'm pretty sure that the shell I'm using is called the bash
shell, but I don't know how to find out. And how does that affect how I work
with the system? For example, if there's another shell that's better, what
is it, what does better mean, and how to I turn it on. 

         

        Like I was thinking of making aliases for cp and rm that
automatically run the -i option to keep myself from trashing stuff. 

         

        Someone please hold my hand and tell me it'll be all right. <grin>
