RHEL 6 as Cobbler server

[Daniel Kertby]

Hi all,

Im quite new to Cobbler and have evaluated it on Centos. However, we are now
moving
Cobbler into our production environment which also then includes RHEL 6 as
OS.

I have been looking around but Im a bit confused how to setup Cobbler in the
best way on RHEL6.
Which repo to use, how to solve the dependencies (pyYAML etc..) without
messing up
the RPM database.

Recommendations how to get a clean install would be VERY APPRECIATED!

Thanks in advance,

Daniel

Afaik, pyYAML is on RHN so setting up epel and RHN could do the job

RHEL6 is doing fine here for me.

Yes, its in epel, packaye PyYAML.
Just one thing, in case you hit problems with the cobbler 2.0.10 from
epel try stepping back to 2.0.9 .

Thanks for a quick reply.

Does this mean that I can install Cobbler for RHEL 6 from the EL 5 x86_64 /
testing repo?

I don't know if that'll work.  I'd suggest using the package from the
EPEL repo for RHEL 6.

[Daniel Kertby]

Ok,

Ok, the repo was added (had to comment out the mirrorlist and uncomment
baseurl.

However, when trying to install cobbler, I get

Yum now detects the required packages but could not find fence-agents
Error: Package: cobbler-2.0.10-1.el6.noarch (ehel6-x86_64)
           Requires: fence-agents

Any hints?

Is there any way to get cobbler-2.1.0 for RHEL 6 as rpm package?

This is part of the HA addon.
Interesting for cobbler for resetting servers via fence agents.

It's used for the remote power on/off feature.

[Daniel Kertby]

Thanks for the info, If someone could give me a clue how to get the 2.1.0
release onto our RHEL 6
server without to much fiddling, it would be appreciated.

Thanks,

I just
- made a copy of the contents of the rhel6 dvd
- run createrepo on it
- added a new repo:
cat >/etc/yum.repos.d/localdir.repo<<EOT
[localdir]
name=localdir
baseurl=file:///mnt/store/cobbler/x86_64/rhel-server-6.0
EOT
- and installed it via yum (actually yum resolves it automatically
as dependency for cobbler then)

Alternatively if your server is added at a satellite or RHN you could
add the HA software channel for the system.

According to the EPEL page, you need to enable the "optional" repository
to use EPEL for RHEL 6.
> Is there any way to get cobbler-2.1.0 for RHEL 6 as rpm package?

For now, I think the only solution is to build it yourself or to see if
someone has already built it.  I would expect an official(-ish) RPM to
be built in the near future.

Thanks again,

Does anyone know how solve the required fence-agent issue on RHEL6?
Another question, is there any company providing support for Cobbler?

Im struggling to get things to work, consider to go live on RHEL 5.5 but im
fightning
a yum update issue when doing yum update after adding the EPEL repo...

Our environment will within a year from now most probably perform 1000-2000
installations
during a 12 month period, perhaps even more. I need a stable Cobbler
environment up and running
right now! :D (on RHEL...)

You could download the rpm and install it separately for right now from:

http://pkgs.org/centos-6-rhel-6/centos-rhel-x86_64/fence-agents-3.0.7-4.el6....

As for cobbler support Red Hat - supports Red Hat Satellite which utilizes cobbler as its engine for installation - might want to look into that if you want 24/7 support.

Thanks Tim, stupid question: What repo should I use solve the fence-agents
dependencies? Hand picking the packages
seems time consuming...

You could try doing yum info fence-agents --enablerepo=* and see what it
returns.  You might have to do disable specific repositories for this to
work.

Any package required by the version of cobbler in EPEL should be present
either in EPEL or in one of the RHEL repositories.

Unfortunately, I don't have access to RHEL 6 (and CentOS 6 isn't out
yet) so I can't tell you specifically where you'd find it.

It actually comes from a couple of satellite channels. Next stable
release I'm going to remove the dependency. Cobbler degrades properly
when the package isn't there, so it really shouldn't be a dependency.

[Daniel Kertby]

Thanks guys!

I got it working, the main problem was that the local repo wasn't correct
setup for the ha repo ( as pointed
out in this thread required for fence-agents).

Thanks alot again for excellent assistance!

Hi again,

Im still fighting to get it all working! Puh!

Conclusions so far (could be useful for you developers to know about) from a
cobbler beginner.

* Wow, so difficult to get the latest version up and running on RHEL6.
  No RPMs with 2.1.0, still stuck with the 2.0.10 version.
   - Anyone know how to get 2.1.0 in on RHEL without dependency    problems?

* cobbler get-loaders failed. Seems to exist a bug id when trying to
  pull the files from the web behind a proxy. I downloaded the files with
wget. A time killer trying to get cobbler get-loaders

* cobbler add distro for RHEL6 fails,
   ....
   found content (breed=redhat) at /v ...
   ...
   Exceptions occured:
  ...
   Also a known issue. Some thread indicated a missing
   https://fedorahosted.org/cobbler/ticket/482

So, I really appreciate the time you developers have put into Cobbler.
As a new user that need to get Cobbler up and running on RHEL6, serving
RHEL6 and other distros/versions, this trip has been time consuming and has
really lead to frustration.

Any clues/hints to get things to work and get a solid/stable setup is VERY
appreciated, I know Cobbler is the right choice for our business.

Regards,
Daniel

I've got it working.  I'm just starting to use it.  I'm going to start
sending in patches for it to work and to fix the freebsd support we
added awhile ago.  You won't be able to use it in the current release.
 Things changed in the rhel6 version like the location of tftpboot.
That's honestly the only real change I can remember from setting it up
last night.  Anyway stand by and in the mean time just don't use
rhel6.  Use something that you know works.

2.1.0 is a development release. I really wouldn't recommend using it
unless you know what you are doing.

I believe we fixed this and it should be out whenever I get a moment to
release 2.0.11.

Can you get me the complete exception? I've not seen this and I'm
running cobbler on RHEL6 right now. In fact, I don't think I have any
cobbler servers that are not RHEL6.

Can I see a copy of your settings and modules.conf? Clean them of any
sensitive data as well.

Hi,

I haven wiped the server yet so I will wait some more! =)

I have attached some debug info, let me know if I need to provide you any
additional.
The system has not yet been updated using RHN but will mostly be during the
day.

Thanks!

Looking at your settings and modules.conf, I don't really see anything
out of the ordinary. However, I would recommend downgrading to cobbler
2.0.9[1] if you are running cobbler on RHEL6. There is a slight bug in
2.0.10 that affects kickstarts and makes cobbler pretty useless.

As for your particular error message, I'm curious, which iso are you
using to do the import? I just did a fresh install of cobbler 2.0.10
(with a small patch to fix the kickstart problem) and it worked
properly. I used the one obtained via RHN[2]. The error I'm seeing in
your log file is very odd. I am thinking it is unable to actually find
the base directory. I don't really see how that can happen. The only
thought I have is a corrupt ISO of some sort.

Thanks Scott for your support.

I did a fresh install in a virtualized environment which didn't give any
import issues, so I wiped the dedicated server this morning.

I decided to not disable SElinux this time and cobbler import fails because
of
the "setsebool -P rsync_disable_trans=1" which cannot set that boolean (not
existing
in RHEL6 as I understand). Any workaround for this?

I will downgrade to 2.0.9[1] per your recommendations. Any link for it?

Thanks in advance,
Daniel

In truth, I tend to run the main cobbler server in permissive mode. The
cobbler servers that people have access to (and replicate off of the
main one) are in enforcing mode. I plan on fixing this, there seems to
be a couple of things that stop you from doing imports and other such
stuff in enforcing mode currently.

I'm about to release 2.0.11 (today if I don't find any terrible
bugs). So hopefully it should hit epel-testing sometime tomorrow. I
would personally wait for that. It should show up in koji in a couple
hours (if all goes according to plan).

Thanks Scott!

I will catch the RPM as soon as it shows up.

We now have the cobbler server up and running on 2.0.9 and it works. It's
not in production, so an upgrade is welcome.

A General QUESTION,
The dhcpd.conf file has subnet definitions for the VLANs we have and it get
the correct next_server for the VLAN in question. Although, is it possible
to have the ks=<ip>... entry in the pxelinux file for a client to get the
same ip/hostname as specified as next_server in the dhcpd.conf file?

My finding so far is that I have to specify --server= when adding a system
to cobbler to alter ks=<ip>... I don't want the profiles to have that info.
We want to avoid routing the installation data over the firewall since it
will generate significant load and also requires us to open firewall rules
for forthcoming VLANs.

Thanks in advance,

Daniel

The sync isn't really failing. It is only failing to restart dhcpd. I'd
run dhcpd -t manually and check /etc/cobbler/dhcpd.template and
/etc/dhcp/dhcpd.conf to figure out why dhcpd isn't liking its
configuration. dhcpd.template is used to generate dhcpd.conf.
