Determining the Path That a Yum Package Installed To

Determining the path that a yum package installed to

yum uses RPM, so the following command will list the contents of the installed package:

$ rpm -ql package-name

to what location on disk does yum installs python packages by default?

I got it by little bit of digging ,

I searched like this :

rpm -ql python2-rpdb-0.1.5-2el7.1.noarch

its installed in the /usr/lib/python2.7/site-packages folder

or in /usr/lib64/python2.7/

Yum Installed Package But I Cant Find It

You did not install soundtouch package, yum is telling you that this package is obsoleted by libsoundtouch. You can check which files belong to that package:

rpm -ql libsoundtouch

How to list the contents of a package using YUM?

There is a package called yum-utils that builds on YUM and contains a tool called repoquery that can do this.

$ repoquery --help | grep -E "list\ files" 
  -l, --list            list files in this package/group

Combined into one example:

$ repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

On at least one RH system, with rpm v4.8.0, yum v3.2.29, and repoquery v0.0.11, repoquery -l rpm prints nothing.

If you are having this issue, try adding the --installed flag: repoquery --installed -l rpm.

DNF Update:

To use dnf instead of yum-utils, use the following command:

$ dnf repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

Best way to check for installed yum package/rpm version in Ansible and use it

The way you do it is perfectly fine. The check which is causing the warning is very simply and just checks the first word against a pre-defined list. It ignores further options and often results in warnings which can not be solved with the corresponding module, like in the yum case.

To get rid of the warning you can simply do a which:

shell: `which yum` list installed custom-rpm | grep custom-rpm | awk '{print $2}' | cut -d'-' -f1

which looks up the the complete path of yum, which then is executed. It's the exact same thing, but from viewpoint of Ansible it calls which, not yum which avoids the warning.

If you want to deactivate this kind of warnings globally you can set command_warnings = False in your ansible.cfg. (See docs)

According to the docs you can also add warn=no at the end of your command but this really looks strange to me as it appears to be part of the command.

Can yum tell me which of my repositories provide a particular package?

yum list packagename

That will show from which repository the package is in the third column of the output.

For already installed packages, that won't work, as the third column shows just installed. In that case you can do e.g. rpm -qi packagename, typically the Vendor, Packager and Build Host tags will give an indication to which repository the package belongs. Also it's quite common for some repo symbol being appended to the package version number.

Determine if package installed with Yum Python API?

import yum

yb = yum.YumBase()
if yb.rpmdb.searchNevra(name='make'):
   print "installed"
else:
   print "not installed"

How do I find out w/YUM or RPM what files it installed?

Use the --filesbypkg argument for rpm.

rpm -qi --filesbypkg nx

How to list installed packages from a given repo using yum

On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:

yumdb search from_repo repoid

(or repoquery and grep -- don't grep yum output).
However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:

http://james.fedorapeople.org/yum/commands/find-repos-of-install.py

As floyd said, a lot of repos. include a unique "dist" tag in their release, and you can look for that ... however from what you said, I guess that isn't the case for you?
