Download rpm installer file for already installed packages

If you have not install the packages, you can always use --downloadonly flag to just download the packages without installing. For example, I want to download rpm file for curl

# yum install --downloadonly curl

The file and its dependencies will be saved into /var/cache/yum.

But if you have installed the package, the above command will only return a message saying that "Packages is already installed, and nothing to do."

In order to download rpm file of an installed package with dependencies, another command is needed, which is repotrack, that is a command in yum-utils package.

First, install yum-utils

# yum install -y yum-utils

Then, run repotrack on the package that you need the rpm installer

# repotrack curl

All the packages will be downloaded to the current directory. Nice!
