@Andrew Rankin
It worked.
I downloaded the entire rpms for centos4,8 and created a local repo inside the chroot.
Your scripts helped with the rest of the problems,. Scripts needed some modification to suit my system, like location of the insight, cshrc files etc.
Thanks for your help
S, Thiyagarajan

@Sam Chen It should work in either RHEL or CentOS. @Chris Bowerman @S. Thiyagarajan He didn't, unfortunately. I'll post the automated installation script I use, maybe that'll get you further along.

Hi
I tried to work what you said. I was successful up to creating the 4.8 chroot environment but have no clues how to get into chroot, how to yum inside the chroot or run insightII. can you give a more step-by-step guide there.

I have CentOS 5.6 installed. created /rhel_chroot dir and installed all the rpms as you have mentioned. my chroot is located at /usr/sbin/chroot. Please help.

Thanks and regards
Thiyaga

Andrew,

I was wondering if John Bollinger ever sent a you a list of packages and/or his method of running Insight on RHEL5. I’ve got a few scientists here that won’t give Insight up, but I’ve got to put them on a new OS than RHEL4. If you do have a list or instructions that you used could you send them to me.

Thanks,

Chris.

@John Bollinger
John, do you mind giving me the list of your final set of RPMs?

Andrew,
I tried your method in RHEL5 but it does not work. I am going to try on Fedora 14 and see how it goes. Do you mind giving me a few suggestions?

Thank you very much!
Sam

John –

Glad it worked for you too! If you have a list of your final set of RPM’s I’d love to see it.

Thanks,
Andrew

Thanks for this, Andrew.

I was faced with precisely the same problem, and no amount of fiddling with v4 libraries and LD_LIBRARY_PATH overcame it. I didn’t want to maintain a separate (possibly virtual) machine just for Insight II, so I gave your approach a spin. It worked like a charm.

FWIW, I was able to reduce the size of the image to 256MB by

1) Not installing RPM, Yum, or any of their otherwise-unneeded dependencies (e.g. Python) in the chroot environment. To do this, I performed all installs externally, using rpm –root.

2) Not installing certain RPM dependencies (rpm –justdb and/or –nodeps) that are needed only for a real, bootable machine (e.g. kernel, initscripts).

In the end, I found I needed only 49 packages.

Cheers!
