How to install changed source file using puppet? - puppet

I changed a source file in for one of my puppet modules, but an older version is already installed. How do I re-apply puppet so that it installs the new package?

A puppet run would make sure that the new file is present.
If you want to remove the older version, you can use ensure => absent

How to properly build package from sources

I'm using ubuntu 18.04.
I want to modify and build a project and install it as a package. For example gstreamer1.5.
So I clone repo, modify code and use ./autogen.sh and make install in project folder. Why don't I see it in apt list then? Also there is no files in /usr/lib/x86_64-linux-gnu/gstreamer-1.5/.
The reason why I want it to behave as the original package is becase I want to build another project that uses it (kurento media server). So I just want to remove some plugins I don't need that use another packages as deps I cannot use.
apt list is from the Linux distribution. You custom made things won't appear there magically.
If you make install from your custom tree your libraries and plugins will land in /usr/local/lib/.. (note the local path). You may have some control over it by setting the prefix path. Just be careful you don't break you system by overwriting with broken libraries.

Installation bind from sources

I trying to install bind from sources on Fedora 24. I have a big problem. After installation, directory like /var/named or file named.conf does not exist. I was trying to create it manually but it didn't work too.
And my question is: where can i get that files? I know that if i install bind via yum, those files will be created properly, but then bind won't be in the newest version.

How to install two different versions of same rpm and make them work parallely

Currently I am trying to install a rpm secured_soft_2.0.0.rpm and i am
unable to install it as we already have secured_soft_1.3.0 installed.
Requirement is that we need to have both the versions installed.
Complexities :
These package inturn have dependent rpm's (lot of them ) and all these
interdependent rpm's also have versions
ex: secured_soft_1.3.0 works only with packages which are of version 1.3,
and secured_soft_2.0.0.rpm work only with dependecies of version 2.0 only.
So all these dependencies also need to be reinstalled and even these
dependenies should be parallely installed, without deleting old.
Finally , both these versions contain shared libraries and these shared
lib's do not have version numbers in their name.
#rpm -ivh secured_soft_2.0.0.rpm
error: Failed dependencies:
init-class >= 1.4.17.1-1 is needed by secured_soft_2.0.0.rpm
init-connection-interface >= 2.0.11.0 is needed by secured_soft_2.0.0.rpm
init-logger >= 2.0.11.0 is needed by secured_soft_2.0.0.rpm
init-security >= 2.0.11.0 is needed by secured_soft_2.0.0.rpm
As i have specified we already have secured_soft_1.3.0.rpm installed and
above dependencies are also available but of different version.
So we need the to install above dependencies and also need the old version's
of dependencies for the old rpm's to work
ex : secured_soft_2.0.0.rpm has libArt.so libSec.so and so on
which are copied to /usr/lib
Similarly secured_soft_1.3.0.rpm also has libArt.so libSec.so and so on
which are already available in /usr/lib
I tried to rename the so's but still iam not able to install.
Is it possible to change the location for these so's and get the things done
Is there any way we can do it.
At the moment, iam stuck here and would need advice on this
Appreciate any help on this.
Since the programs use the same filenames, and you need to put them on the same machine, you might be able to move the older version to another directory tree and make it work there.
You can do this with many applications which do not have compiled-in pathnames.
For instance,
install the older version (this sounds like where you are starting from)
use rpm -ql for each of the packages containing unversioned executables, libraries and associated files.
use tar to capture an archive of those files, relative to /usr (but omitting directories not owned by the packages).
create a new directory, e.g., /usr/local/myapp and untar the older version there.
update configuration files in the new location as needed
For applications such as this, I would run in a script that updates PATH (and perhaps sets LD_LIBRARY_PATH) to force the program to run from the new location. You can verify if this works using tools such as strace and lsof, i.e., by looking for the files that the program opens.
Once you have the older version working properly in the new location, you can uninstall its rpms and install the new version of the application.
Caveat: If the newer package is copied from a newer version of the operating system, however, the task is likely to be beyond your ability, whether or not you choose the alternative approach of recompiling the newer packages to fit on the existing system.
Building new/custom packages is one route to recompiling the newer version. If you have the source-RPMs for each part, that is a starting point:
extract the files from the source-RPM, e.g., using a script such as unrpm (see for example HowTo: Extract an RPM Package Files Without Installing It), and
copy those extracted files to their as-expected locations in your build-tree, e.g., $HOME/rpmbuild/SOURCES and $HOME/rpmbuild/SPECS
modify the spec-file to use the alternative location
build the new/modified package using the modified spec-file.
No, out of the box, you cannot.
I'd highly recommend looking into Docker, where you can throw each one into their own container and let them take care of all their dependency problems.

rpm upgrade | add new files without removing the old ones

I develop a software which is distributed and installed via rpm. During install, I copy some binaries to a destination directory.
When performing rpm upgrade, I'd like the old binaries not to be deleted, and that the new ones will be added as is.
Is there an rpm built-in way to do so? I'd really like to avoid scripting in order to resolve that...
EDIT:
The above binaries were listed in #files section.
If you are manually copying the files to some directory (in %post for example) then yum/rpm doesn't know anything about them and can't remove them.
If you have them listed in the %files section (i.e. copying them to the right place under buildroot during `%install) then no, I do not believe you can have rpm leave files not listed by the new package on the system after upgrading to a newer version of the package which does not contain those files.
It might be possible to play with marking them as %config files and then "modifying" them so that rpm won't remove them but it might still rename them and I don't know if this will actually work.

List of changed files in RPM

I wonder, if there is a way to do the following:
I have rpmA-v1 installed on the system. It has a lot of config files which user can edit for their purposes. Then, I want to install new version of rpmA, say, rpmA-v2 and before installing it I want to back up those config files, which were edited, not to edit config files one more time.
Is there any way to know which files were edited in such a situation?
If you are talking about config files related to given package, rpm already has pretty robust mechanism for this known as .rpmnew/.rpmsave.
If package is being upgraded, at the discretion of package creator/maintainer there are 2 possible actions that may be taken by rpm:
Old config is preserved intact say at /etc/myprog/config, and new one is installed right next to it as /etc/myprog/config.rpmnew. Presence of *.rpmnew file typically means that old config was NOT edited.
Old config is renamed to /etc/myprog/config.rpmsave, and new one is installed as/etc/myprog/config (replacing old one). New config may be completely fresh (vanilla) or it may incorporate settings inherited from old, .rpmsave'd version. Presence of *.rpmsave files is pretty robust sign that config files were actually edited by rpm.
Typically, after upgrading of one or more packages (or the whole system) it is recommended to search for all .rpmnew/.rpmsave files using command like
find /etc -name "*.rpmsave" -or -name "*.rpmnew"
and carefuly inspect all configs against their .rpmnew/.rpmsave versions (if they are around) to make sure that settings are correct. You can use diff -u to see text diffs or meld for graphical diff/merge.
#mvp has provided a good way to determine changed config files - provided they are marked as such.
If they aren't, you can/should verify the installed package with rpm -V packagename in order to display any changed files.
