Download RPM packages for command which is already installed

Question

I have a CentOS machine in which I already installed openssl-devel using

$ yum install openssl-devel

It downloaded and installed all the dependency packages. Now I need all those RPM packages. Is it possible to download only the RPM packages? When I do this:

 $ yum install  openssl-devel -y --downloadonly

It says

Package 1:openssl-devel-1.0.1e-4.fc18.x86_64 already installed and latest version

since it's already installed.

Does anyone know how to download those RPM packages on the same system?

It is possible to download the packages of an RPM which is already installed using the --downloadonly switch. I am not sure why yum doesn't check this setting before checking whether the package is already installed, but I guess it could be caused by the underlying architecture of the tool.

Anyway, all you need to do is to tell yum to reinstall the package:

yum --downloadonly --downloaddir=/tmp/rpm_files/ reinstall package_name

Of course, yum will not know which dependencies were installed just for this package, so if you take the RPMs and try to install them on a different system, some dependencies might be missing. There are ways to explore the whole dependency graph and I'm sure this was already described elsewhere on SE.

yumdownloader in yum-utils will download any packages you pass to it, or optionally generate the URLs the packages can be downloaded from.

its not resolving dependencies , it just download openssl-devel.x86_64.rpm – abubacker May 17 '13 at 12:46
No, it doesn't resolve dependencies. But how far back would you like the tool to resolve the dependencies? `glibc`? `filesystem`? – Ignacio Vazquez-Abrams May 17 '13 at 12:47

my requirement is simple , i need to get the list of rpms , to install it on another machine , which is in offline – abubacker May 17 '13 at 12:50
You say "simple", but it's actually not as simple as you think. There is no tool that will resolve dependencies given just a list of which packages are already installed. – Ignacio Vazquez-Abrams May 17 '13 at 12:52

actually it is simple , yum install openssl-devel -y --downloadonly if i do this command on an another machine , it will resolve all dependencies , but my question is whether its possible to do the same in a machine which we installed that command already – abubacker May 17 '13 at 12:56
"It's simple, but with caveats" is *not* the same as "it's simple". – Ignacio Vazquez-Abrams May 17 '13 at 12:57
ok let it be tough as per u say , my question is whether its possible or not – abubacker May 17 '13 at 13:00
Yes. But it's not trivial. No tool is designed to resolve dependencies given just a list of which packages are already installed. – Ignacio Vazquez-Abrams May 17 '13 at 13:01

You can use the repotrack command from the yum-utils package. It will download the entire dependency tree - even if it is already installed.

Example:

sudo yum install yum-utils      # Install yum-utils
sudo repotrack openssl-devel    # Download all dependencies for openssl-devel

Sample output:

[sbadra@rhel6 ~]$ sudo yum install openssl-devel
Loaded plugins: product-id, search-disabled-repos, subscription-manager
Setting up Install Process
Package openssl-devel-1.0.1e-57.el6.x86_64 already installed and latest version
Nothing to do

I retracted the note about the architecture bug since it is actually the expected behavior. (x86_64 is a superset of i686, which is why the command also downloads i686 packages) See [this](https://github.com/rpm-software-management/yum/issues/25) and [this](http://yum-devel.baseurl.narkive.com/h43gi3vs/why-doesn-t-reposync-work-for-me) article for more info. — Sami Badra, Feb 23 '18 at 21:16

One possibility in the longer term might be to designate a machine as the one to download from the internet, then run NFS (or a webserver) on it to expose /var/cache/yum to the internal hosts.

You would then need to update your yum config, to add:

[main]
keepcache = 1

Per https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sec-Working_with_Yum_Cache.html:

Once you enabled caching, every yum operation may download package data from the configured repositories.

In more practical terms:

$ sudo yum install -y nginx
$ sudo find /var/cache/yum/ -type f -name '*.rpm'
<...snip....>
/var/cache/yum/x86_64/7/epel/packages/nginx-1.10.2-1.el7.x86_64.rpm

The other answers will actually solve your immediate issue, where this will only help if you run yum reinstall for the packages you already have, and want RPMs for.

Here's what I do:

sudo yum install --config=./yum.conf 
  --installroot=/tmp/f541Sdex 
  --downloadonly 
  --downloaddir /tmp/DL-e25xds 
  $(cat list-of-packages)
