I have two web servers, a production web server and a backup web server.

After running a rpm -qa on the two servers, I noticed some package discrepancies.

It seems like, someone ran a yum update at some point in the past on the production server, but did not run it on the backup web server.

I would like to install a few very specific packages on the backup web server.

for example : yum install bind-libs-9.8.2-0.17.rc1.el6_4.5.x86_64

If I run yum install bind-libs-9.8.2-0.17.rc1.el6_4.5.x86_64 it seems to try and find the newest package that matches, and not the specific package I would like.

...
---> Package bind-utils.x86_64 32:9.8.2-0.17.rc1.el6_4.4 will be updated
---> Package bind-utils.x86_64 32:9.8.2-0.17.rc1.el6_4.6 will be an update
...
======================================================================================
 Package           Arch          Version                          Repository      Size
======================================================================================
Updating for dependencies:
 bind-libs         x86_64        32:9.8.2-0.17.rc1.el6_4.6        updates        878 k
...

Is there a way to install only the package I would like and nothing newer?

Another thing you can do which can be a bit more work than previous answer but works as well is to download the package manually and then run

# yum localinstall /path/package.rpm

That should try to install the specific package you downloaded.

  • I was also thinking about manual install, but how would I get the rpm in question? I am not sure how to find a specific rpm with just the information i have. – Nathan McCoy Oct 15 '13 at 12:52
  • Here you go: mirror.centos.org/centos/6/updates/x86_64/Packages/… – Tomas Oct 15 '13 at 12:56
  • rpmfind.net is a useful resource for finding RPMs of various versions from various distributions. – Ruairi Oct 15 '13 at 13:00
  • True. I like to go straight to the distro though but yes, that site is really useful as well :) – Tomas Oct 15 '13 at 13:29
  • I picked your answer because of your help with the mirror and the details about yum. I just appended .rpm to my corresponding packages and downloaded them all with wget (quick bash script). thanks! – Nathan McCoy Oct 15 '13 at 14:48

I believe the following will do what you want, as by default yum won't let you install a release BELOW what's available:

yum install yum-versionlock

and then:

yum --allow-downgrade install bind-libs-9.8.2-0.17.rc1.el6_4.5.x86_64

and to maintain this version in the case of future package updates to your system:

yum versionlock bind-libs

  • You're welcome. Do let us know how it goes. – Ruairi Oct 15 '13 at 12:52
