The best way for individual packages name of which you know is utility yumdownloader  from yum-utils. Th elatter  is a collection of utilities and examples for the yum package manager. It is actually a valuable RPM to study on its own right.

It includes utilities by different authors that make yum easier and more powerful to use. These tools include: debuginfo-install, package-cleanup, repoclosure, repodiff, repo-graph, repomanage, repoquery, repo-rss, reposync, repotrack, verifytree, yum-builddep, yum-complete-transaction, yumdownloader, yum-debug-dump and yum-groups-manager.

On RHEL they are usually installed by default. If not to install use the command

yum -y install yum-utils.noarch

Now use the yumdownloader command which is a program for downloading RPMs from Yum repositories. Type the following command to download httpd rpm file:

[0]root@sandbox: # yumdownloader perl-XML-Simple
Loaded plugins: product-id, refresh-packagekit, rhnplugin
This system is receiving updates from RHN Classic or RHN Satellite.
perl-XML-Simple-2.18-6.el6.noarch.rpm

If packages that you need download are result of update process then you need to use yum plugin yum-downloadonly

yum update yum-downloadonly

This will add two options to yum commands

usage is

yum install perl-XML-Simple -y --downloadonly --downloaddir=/home

You can also get RPMs during normal update or install process

You can also get RPMs during normal update or install process. Before installation, downloaded RPMs are stored in the dir /var/yum/cache

So you can go there and simply copy the rpms after yum downloaded them and waiting your permission to install them.

Unfortunately they are deleted after installation...

[Dec 26, 2016] How To Download A RPM Package With All Dependencies In CentOS

Method 1 – Download A RPM Package With All Dependencies Using "Downloadonly" plugin

We can easily download any RPM package with all dependencies using "Downloadonly" plugin for yum command.

To install Downloadonly plugin, run the following command as root user.

yum install yum-plugin-downloadonly

Now, run the following command to download a RPM package.

yum install --downloadonly <package-name>

By default, this command will download and save the packages in /var/cache/yum/ in rhel-{arch}-channel/packages location. However, you can download and save the packages in any location of your choice using "–downloaddir" option.

yum install --downloadonly --downloaddir=<directory> <package-name>

Example:

yum install --downloadonly --downloaddir=/root/mypackages/ httpd

Sample output:

Loaded plugins: fastestmirror

 * updates: centos.excellmedia.net

exiting because "Download Only" specified

Now go the location that you specified in the above command. You will see there the downloaded package with all dependencies. In my case, I have downloaded the packages in /root/mypackages/ directory.

Let us verify the contents.

ls /root/mypackages/

Sample output:

apr-1.4.8-3.el7.x86_64.rpm
apr-util-1.5.2-6.el7.x86_64.rpm
httpd-2.4.6-40.el7.centos.4.x86_64.rpm
httpd-tools-2.4.6-40.el7.centos.4.x86_64.rpm
mailcap-2.1.41-2.el7.noarch.rpm

As you see in the above output, the package httpd has been downloaded with all dependencies.

Please note that this plugin is applicable for "yum install/yum update" and not for "yum groupinstall". By default this plugin will download the latest available packages in the repository. You can however download a particular version by specifying the version.

Example:

yum install --downloadonly --downloaddir=/root/mypackages/ httpd-2.2.6-40.el7

Also, you can download multiple packages at once as shown below.

yum install --downloadonly --downloaddir=/root/mypackages/ httpd vsftpd

Method 2 – Download A RPM Package With All Dependencies Using "Yumdownloader" utility

Yumdownloader is a simple, yet useful command-line utility that downloads any RPM package along with all required dependencies in one go.

Install Yumdownloader using the following command as root user.

yum install yum-utils

Once installed, run the following command to download a package, for example httpd.

yumdownloader httpd

To download packages with all dependencies, use –resolve option:

yumdownloader --resolve httpd

By default, Yumdownloader will download the packages in the current working directory.

To download packages along with all dependencies to a specific location, use –destdir option:

yumdownloader --resolve --destdir=/root/mypackages/ httpd

Or

yumdownloader --resolve --destdir /root/mypackages/ httpd

Sample output:

Loaded plugins: fastestmirror

(5/5): httpd-2.4.6-40.el7.centos.4.x86_64.rpm | 2.7 MB 00:00:19

Let us verify whether packages have been downloaded in the specified location.

ls /root/mypackages/

Sample output:

apr-1.4.8-3.el7.x86_64.rpm
apr-util-1.5.2-6.el7.x86_64.rpm
httpd-2.4.6-40.el7.centos.4.x86_64.rpm
httpd-tools-2.4.6-40.el7.centos.4.x86_64.rpm
mailcap-2.1.41-2.el7.noarch.rpm

Unlike "Downloadonly" plugin, Yumdownload can download the packages related to a particular group.

yumdownloader "@Development Tools" --resolve --destdir /root/mypackages/

Personally, I prefer Yumdownloader over "Downloadonly" plugin for yum. But, both are extremely easy and handy and does the same job.

[Nov 05, 2014] dsumsky lines . . . YUM download only mode

January 18, 2011 | dsumsky.blogspot.com
How many times I was in a situation I needed to update a server with RHEL installed but I wasn't at site and I didn't have a way how to reboot the server after installing a new kernel or glibc package on it reliably? Yes, I have a test environment and I'm testing the updates on it but many installations are too critical to just run yum update -y and then shutdown -r now. On top of that, there are well known Murphy's laws which are able to damage more than we are able to imagine.

Instead of remote resolution of why the server is suddenly unresponsive I'm trying to prepare some offline update archive (if there isn't an update server available but this is another situation) and then during a site visit to apply it.

As I'm talking about RHEL I'm using YUM or Yellowdog Updater Modified for it. This tool is able to download updates locally without installing them if we have RHEL 5.x system. It only requires to install a download plugin which is part of yum-downloadonly package. Try to install it with

yum install yum-downloadonly

The next lines contain common commands that I use for downloading updates:

yum install PACKAGE_NAME.rpm -y --downloadonly
yum update -y --downloadonly

If we have a RHEL 4.x server we don't have this package and we need to install another package called yum-tools which contains similar tool yumdownloader.

yum install yum-tools -y

Here it is how to use the tool

yumdownloader PACKAGE_NAME.rpm

If we wan't to download all the available updates with yumdownloader we need to get a list of all packages with yum check-update and then to pass it to yumdownloader. You can do it from shell with sed, cut or awk commands or what would you prefer:

for PKG in `yum check-update | cut -d' ' -f1`; do
   yumdownloader $PKG
done
For more detailed description of the tools and their parameters have a look at their man pages.

[Nov 05, 2014] Minimizing Downtime with YUM download only

In case you want to update your Linux system to the latest OS patch level and you want minimize your downtime, you could work with the `yum –downloadonly` option. At least, the time for downloading all your required packages can be saved.

Just install the yum-utils and the yum-downloadonly package, in case not already done.

# yum install yum-utils

# yum install yum-downloadonly

Now you can start your download operation, with or without Kernel packages.

# yum –exclude=kernel* update –downloadonly

# yum update –downloadonly

Your downloaded packages will end up per default in the following directory/subdirectories if not otherwise specified.

# cd /var/cache/yum/x86_64/

Now you can stop your applications and update your OS, with or without Kernel, whatever is desired.

# yum –exclude=kernel* update

# yum update

# reboot

Ready.

Advantage

The advantage of the –downloadonly option is simply that you minimize your downtime. Of course, it depends on the number of packages that have to be updated, and it also depends on your network bandwidth, but you could save from several minutes to hours.

Conclusion

The –downloadonly option is pretty useful, when you want to minimize your downtime.

Cheers, William (kernel@0x01.net)
