If you want to only download an RPM package without installing it, you'll need to install the yum-plugin-downloadonly.noarch package first.  This will then add options to the yum command allowing only downloads of RPM packages without installing them. 

 

This is particularly handy if you just want to download a package for extracting single files or viewing it's contents prior to installing them.

 

Here's how to use it once it's installed:

Install the plugin package using yum:

# yum install yum-plugin-downloadonly.noarch
Loaded plugins: refresh-packagekit, security

Once installed, issue your command to get the RPM:

yum install –downloadonly –downloaddir=./ <RPM / PACKAGE>

Example:

yum install –downloadonly –downloaddir=./
