How to instruct yum to install a specific package (rpm) from a specific repo

Question

If the rpm package is available in multiple repos (configured in /etc/yum.repos.d/ directory), yum is scanning all the repo files and installing it from the one which has the latest version of that package.

I want the package to be downloaded from a specific repo, also I don't want to completely disable the other repositories, instead, I want just one package to be fetched from a specific repo, and disable it from getting downloaded from other repo.

I also don't want to use the version as a filter as there could be the same version of the same package present on multiple repos.

Answer 1

you can tell yum which repositories he can use:

yum --disablerepo="*" --enablerepo="<desired-repo-id>" install package-name

This does not permanently enable/disable repositories; just for this command execution.

The downside of this approach is that dependencies have to be installed beforehand if the enabled repo doesn't have them. – Photoplay

@LucasBustamante which is quite logical... If you have dependencies outside the repositories you use... – Domenicadomenico

Answer 2

If you don't want to disable all repos, then only solution here is to use yum-priorities. It's a plugin.

$ yum install yum-plugin-priorities

Then in a yum repo in /etc/yum.repos.d/*.repo, you can use,

[some_repo]
....
priority=1

Note, the lowest numerical value represents the highest priority. If your package is available in multiple repos, installation/update will occur from the highest priority repo.
