How to download 3rd party rpm packages with all the dependencies for offline installation?

Question

I want to download all the .rpm files for the below packages with all its dependencies. The problem is yum cannot find any of them nor its dependencies. I want all these .rpm files for offline installation in another secluded redhat server.

• protobuf-devel
• leveldb-devel
• hdf5-devel
• gflags-devel
• glog-devel
• lmdb-devel

I am using yumdownloader and I got the below error for the above packages

No package package-name available.                     
Error: Nothing to do 

I used the command below

yumdownloader --resolve snappy-devel

for other packages like

• snappy-devel
• opencv-devel
• boost-devel
• atlas-devel

for which it worked perfectly and downloaded all the packages and the required dependencies *.rpm

Please tell me how to do the same for the other packages mentioned in the beginning.

Answer 1

The problem seems to be that yumdownloader cannot find any package with that name.

Either those packages have different names (try searching yourself using yum search protobuf for example); either you need to add new repositories that do contain those packages.
