installing rpm from ISO

Hi,

I would like to know is it possible to install rpm along its depedable rpm from mounted .iso image on Redhat Linux

while installing rpm it is showing so many depandancy, so I would like to know with single command wheather it will take all depedable rpm from mounted iso image.

With RPM alone it's not possible to resolve the dependencies. That's why yum came into picture. You need to configure a yum repository of the packages you have. You can then install the package using yum. It will take care of everything.

By the way, are you talking about the installation DVD/CD ISO here?

You can follow the steps listed here to build a local repository:

Create a local yum repositories on RHEL
