Hello all,
We prefer to use an automated method to install Centos (Kickstart
Installations).
Here is the link to Kickstart documentations:
http://www.centos.org/docs/5/html/5.2/Installation_Guide/s1-kickstart2-whatis.html
You can setup how you want to disks will be partitioned, setup network, you
can select which packages to install or not to install and the best thing is in
post section you can add users, install rpms and even compile and install
packages ( we've done it with ldm).
The only thing you need is an access to web or ftp server where you put that
kickstart config file and your custom packages (like ldm, rpms or config files).
You can use kickstart file created automatically by anaconda
(/root/anaconda-ks.cfg ) as start kickstart config file and modify it.
The list of packages and group of packages can be found in CentOS DVD
(\CentOS\base\comps.xml).

I just burned the 5.2 DVD yesterday and am getting ready to do the install on
what will become our new PDI ingestor boxes. Thanks for the heads up on some
of the issues.

Subject: [ldm-users] Initial thoughts on CentOS 5.2
Hello all,
All of my servers are now on CentOS 5.2, including my NOAAport server.
For those who have used it or are thinking of getting it, here's what I
think about it so far.
Installation: Centos 5.2 does NOT like some Viewsonic monitors for the
graphical install. Once you got past the "Welcome to CentOS"
page and it started X windows, I got an "Out of range" message
on my monitor. Installing in text mode is much slower if you select
packages you want, like I do. On one machine, it was the only way I could
do it. On 2 others exhibiting the problem, I used a Dell monitor from a
3rd server. This was a problem in Fedora 6/7 that apparently wasn't fixed
for 5.2. I can understand it being there in 5.0, but 5.2...swat that bug!
Especially with a known fix out.
Second issue I had was not finding some packages I needed. After some
pointing from a few of you and some old-fashioned Google hunting, I found
the remainder of the packages I needed. That was frustrating. But, after
the first test server got the installation completed and tweaked, the rest
went pretty fast.
Gnome had a problem where autologin had an error. I log my office servers
into LDM automagically after a boot; it would stop with an error that said
the .dmrc file must be set to file permission 644. But that didn't fix
it; setting the permissions variable did. Finally, on one of the
servers, the keyboard simply stopped working. After finding the
issue on the Ubuntu forums, removing the .gconf directory brought it back,
and all was well. These were known issues in Fedora 6/7; wish they had
gotten them fixed for CentOS.
Now, as for the OS itself: it seems to run fine. LDM, McIDAS and WXP all
ran fine, although I had to recompile LDM because Centos still uses
syslog, while Fedora 8 and later uses rsyslog. Need to try GEMPAK, haven't
had the opportunity yet.
What about the packages? I was pleasantly surprised. I enabled the
updates-testing repository, and doing a large "yum update", I saw I had
Apache 2.2.8, Postfix 2.3.3-2, and Firefox 3.0.5. My previous postfix
config files were somewhat incompatible, but after a few tweaks, it was
fine. I really like Postfix over Sendmail; UNIDATA sold me on it when they
flipped their mailing lists over to it. Sometimes email had long delays,
but now, I usually get any emails within a minute after its sent. Maybe
exim is a bit faster, never tried it, and from what I've read, never want
to...but Postfix is still screaming fast for me.
Anyway, everything has been switched over to Centos 5.2 here.
Yesterday evening, at about 11 PM when I put the final touches on this
server, I opened up a side drawer and saw DVD's for Fedora 8, 9, 10. I
opened up the DVD cases and envelopes, took out the media, and after a
pause, I threw them in the trash. 10 years with Redhat/Fedora, gone. OK,
I know I am still with them, technically. And I'll have Fedora 8
back...when CentOS 6 comes out...in first quarter 2010. :-) But still,
Fedora was really making things less flexible...no root login from GDM
anymore, no SMTP connection allow to let WXP make its images...bad. If I
wanted an OS that was inflexible, I'd choose Windows. I don't know what
I'll do 2 or 3 years down the road when that garbage hits CentOS.
All that having been said, so far, everything is up and working that I had
before. However, to make that happen, I had to do some serious hunting to
get some packages I needed (like the latest versions of Icecast and
Darkice). I don't know when they update their individual packages when a
problem is found, but that will come in time. Now, back to work.
Oh, do I recommend Centos? Well, it's Fedora, isn't it? What's not to
like? :-)
