Re: Sharing yum between several machines

Basically, I would like a system where yum looks first
in a /common/yum/ directory NFS-mounted on several machines,

then it goes to a mirror as before,
and adds what it finds to /common/yum/ as well as installing it
on the machine in question.

Does yum have such a facility?
I googled for "yum several machines" but all the solutions suggested,
eg setting up a local mirror, seemed to me excessive for my purposes.


That's the way I do it here. I have a pair of scripts which handle it. The first mounts the master copy as /mnt/cache and creates symbolic links in /var/cache/yum to the rpm files. Then the upgrade is run, and the "backup" script first lists which files have changed, and then uses rsync to backup the changes. I found this was more reliable than NFS mounting, due to possible conflicts and also laptops being updated over less than perfect connections.

Note that doing this way does not delete old copies of the packages, which may or may not be desirable. I have a script which finds the deleted packages and backs them up by moving them, that way I have older stuff should I need it for some reason.

If you have solid networking and don't need the old packages you can just NFS mount /var/cache/yum (don't run multiple upgrades at the same time).
