Redhat Cluster suite package?

LinuxLover · 06-28-2008, 01:21 PM

helo every one,

I am going to practice with RedHat Cluster suite, on RHEL 5.1

I am getting confused about the Cluster suite package,

In my RHEL 5.1 DVD I have two direcotries with the name Cluster and ClusterStorage.
Cluster direcory have the packges like luci,ricci,rgamanager , pirhana,system-config-cluster etc

and clusterStorage direcoty contail gfs, lvm2 ,gnbd etc packages.

Now my question is that , is there a separate package with the name of

"Redhat Cluster suite" which I have to install for cluster configuration or the packages mentioned above or enough to configure the cluster.

You're looking in the right place. There is no package named "Red Hat Cluster Suite", CS is provided by the combination of cman, rgmanager, and system-config-cluster. Instead of system-config-cluster, you can also use luci + ricci. You really don't need both system-config-cluster and luci/ricci on the same cluster, since they are both just configuration interfaces. I've found system-config-cluster to work more reliably, especially when you don't have access to the Cluster Suite RHN channels.

lvs/Pirahna provide a load-balancing cluster, while cman/rgmanager/etc. provide high-availability clustering. When you see references to "Red Hat Cluster Suite", most people mean the high-availability services provided by cman and company. lvs is technically part of Cluster Suite, but it provides a different kind of clustering. So make sure you know what you're using, and that it's what you want.

If you want GFS, you'll want to install the gfs, lvm2, etc. packages from ClusterStorage. Offhand, I don't recall every package you'll need; I may be missing some here.

Lot of thanks jpwigan

You got me out of confusion,

You said you use system-config-cluster ,

In Redhat docs regarding cluster , they seem to prefer CONGA web interface for cluster in RHEL 5.

I am practicing with both , but conga looking easy to manage,

Once again thanks

From my experience, Conga is easier to work with from an administrative standpoint, but has a tendency to cause unexpected problems. Anyway, try them both, and use the one you like!

Hi, I wanted to do a POC on RedHat Cluster Suite. I have installed RHEL 5.2. I don’t know how to install RHCS from RHEL 5.2. I could also see a folders named as "Cluster", "Cluster Storage". I have gone thru few links and they asked to install via Add/Remove software. But i couldn’t see any packages. RHEL 5.2 consists of 5 CD's, but while installing it asked me 4 CD's only. I don’t know, whether this caused the problem or not. Pls help me to install

Note:

I need a two node cluster.

Is it really necessary to register with RHN?

Thanks in Advance,
Mohan

Carefully Follow up with this Doc line by Line And you can get the Red Hat Cluster Suite Setup in no minutes.http://www.centos.org/docs/4/html/rh-cs-en-4/
Don't forget to say "thanks"...Just kidding

Hi,

Thanks for your IMD response.

But I have already gone through this link. They asked to install via up2date command. I have tried that too, but it has given an error.

QSNs:
1. How can I get the Conga GUI?
2. I dont see any stuff called "system-config-cluster"
3. Is it really necessary to reg with RHN?

Rgds,
Mohan

Its not necessary to register with RHN. You can get all these package through rpmpbone.
Just google rpmpbone.

Do try this too:
ftp://ftp.redhat.com/pub/redhat/linu.../en/RHCS/SRPMS

your_shadow03 · 07-06-2009, 06:58 AM

ftp://ftp.redhat.com/pub/redhat/linu.../en/RHCS/SRPMS are the list of required RPM. Just see which architecture you are on and search for these packages.Hope yu know how to build RPM from SRPM

mohbrsu · 07-06-2009, 07:09 AM

I think RHEL 5.1 package comes along with these rpm's. I could see all the rpm's in the CD. Anyother way to get it installed from the CD?

chrism01 · 07-06-2009, 08:53 PM

If you want to be able to keep your system updated, either
1. register (inc payment) with RHN
OR
2. use CENTOS instead

don't try to mix the two, as the repo settings will be wrong.

The pkg mgr for RHEL/CENTOS 5.x is 'yum'. up2date was for v4.x (and earlier).

You can install the Cluster sw from the CD (x 5) or DVD (x 1). I'd suggest getting the DVD, less messing around.

Hope that clarifies things.

Hello Chris,

I have used the yum groupinstall clustering & I got the following error

# yum groupinstall Clustering
Loading "Security" plugin
Loading "rhnplugin" pulgin
This system is not registered with RHN
RHN support will be disabled

Could you pls help me out in this?

FYI- I've installed RHEL5.2 and I couldn't see any packages after installing RHEL5.2. But I could see the packages in a CD.

I use CentOS, but do you have some form of media repo in /etc/yum.repos.d?

mohbrsu · 07-07-2009, 01:07 AM

Ya, I have two repo files in /etc/yum.repos.d/

Files: cluster.repo & rhel-debuginfo.repo

nxt?

Here's the content of my CentOS_Media.repo. Create something similar, mount the dvd and see how you go. You may need to disable the other repos. You may also need to comment out the key references.

Code:

# CentOS-Media.repo
#
# This repo is used to mount the default locations for a CDROM / DVD on
#  CentOS-5.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c5-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c5-media [command]

[c5-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS/
        file:///media/cdrom/
        file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
