Hi,

I have some problems in installing and configuring Conga on RHEL-5 (2.6.18.8) with cluster defined on Dell CX300. I have following doubts.

1)I have not entered subscription key on RHEL-5 for activation.

Can I configure cluster on it?

2)I have two Linux servers and I want to configure a cluster for both.

Do I have to install ruci agent on both ?/

3) I have installed luci and conga on one of the linux server.When I try to locate conga or luci file, I am unable to find any relevant file.

What is default location of these files?

4)I install conga and when I reinistall this no error is displayed that the package is already installed.

Why ??


5) Can anybdy provide me the prerequistes fo rinstalling conga and luci agent ?


Please clarify these issues?

If you have the official GFS and Cluster Suite Packages that can be downloaded as ISO from RHN you can install them from CD.

Although not adviseable for productive environments you may also install CentOS packages on your RHEL 5 system. While those packages aim to be compatible, it is not guaranteed to work. Also sometimes the packages are a not updated as much as the official RPMs.

Other advises:
We work with GFS and Cluster Suite on daily basis and we do not recommend the graphical management tools like system-config-cluster or conga at the moment. Editing config files directly and using the shell to administer the cluster works best. Also you should not use GFS 2.

Thanx for replying.

As you said , graphical tools such as conga is not recommended. Can you tell me the limitations of these tools so that I can discuss these issues with Management and recommend them for manual/shell clustering .

No, the ricci agent has to be installed on each server you want to have managed by conga.
luci is the webinterface. Basically an adapted plone (see www.plone.org).
How did you try to locate these files?
/var/lib/luci or rpm -ql luci are your friends.

That sounds cute. How did you install what packages?


For luci you need some things like python, xml-libraries for python and the like. Normally the rpm should deal with those dependencies.
For ricci there isn't very much except some xml/ssl-libraries (as far as I remember).

Have fun and keep in mind what Mr. McGee said ;-) .

About the limitation of conga and system-config-cluster is that they cannot solve or build a valid cluster.conf on any possible cluster (fencing configuration or any other specialities).

And most important anybody who wants to setup a cluster should deal with the backgrounds and ideas behind it. GUIs don't really help you with this. Afterwards they are nice toys.
