Hello and welcome to LinuxQuestions,
The first thing you need to do is provide a descriptive title for your thread since 'Help soon' doesn't say anything about your question/problem. Using titles like that don't get the attention your post might deserver. If you want to know how to ask a question then please read the link in my signature.
A quick Google search gave me as first link:
man createrepo
I believe that's what your looking for, so it's good practice to always search first in Google.
All of that being said, enjoy Linux, and welcome again.
Kind regards,
Eric
