Iwould like to only download the packages via yum and not install/update them. How do I download a RPM package using yum command under CentOS Enterprise Linux server 5.x or RHEL 5.x systems?
You need to install plugin called yum-downloadonly. This plugin adds a --downloadonly flag to yum so that yum will only download the packages and not install/update them. Following options supported by this plugin:
[a] --downloadonly : don't update, just download a rpm file
[b] --downloaddir=/path/to/dir : specifies an alternate directory to store packages such as /tmp
[b] --downloaddir=/path/to/dir : specifies an alternate directory to store packages such as /tmp
Please note following instructions are only tested on CentOS server but should work with RHN and RHEL without any problem.
