lg. asked:
After I have installed a package by yum (with multiple repositories configured), how can I find from which repository it has been installed?
If I run yum info package-name (or yum list package-name), I can only see that the package is “installed”.
My answer:
If all else fails, you can inspect the yumdb manually. It’s located in /var/lib/yum/yumdb and contains detailed information on every installed package. You’ll be particularly interested in from_repo. For example, for the bind-utils package:
# for i in /var/lib/yum/yumdb/b/*bind-utils*/*; do echo $i: `cat $i`; done
/var/lib/yum/yumdb/b/73ea08770fa666e18c59842bf65fa0f3a0b103d8-bind-utils-9.8.2-0.23.rc1.el6_5.1-x86_64/checksum_data: 39f7840f93d3d76825a9e8da79cfe0366f7fad68f018a273477aee62cccfa3f4

To get just the information you want:
# cat /var/lib/yum/yumdb/b/*bind-utils*/from_repo
updates
Later versions will provide even more data; for instance in EL 7 the exact mirror and URL from which the package was downloaded is stored here.
