Setting up YUM on my local machine 😎

Why YUM ?

Yum is an automatic updater and package installer/remover for rpm systems,But i think rpm also does the same thing then why do we need yum ?Yes rpm also does the package management in rpm based machines but it does not handle dependency resolution which is taken care very well by yum

It automatically computes dependencies and figures out what things should occur to install packages. It makes it easier to maintain group of machines without having to manually update each one using rpm. Yum has a plugin interface for adding simple features. Yum can also be used from other python programs via its module interface.

It has been so much of theory i guess, lets jump into the practicals

Note: This post is tested on rhel 5.7 and will work well on 5.x(works well for all rpm based machines) i will drop comments for rhel 6 and 7 , This is tested on Vmware Workstation

Pre-requisites:

One RHEL/Centos (5.x) machine on Vmware or Virtual Box, I have used Vmware workstation and RHEL 5.7 in this article

Steps:

1. Attach the CD/DVD to the Virtual Machine

2. Mount it to File System or Directly user the files from /media

3. Install Createrepo Application(program using rpm)

4. Create a Repository folder on your local Machine and copy all files from disk to this folder

5. Make the folder as repository using Createrepo

6. Make a configuration file in /etc/yum.repos.d/ and import gpg keys using rpm

7. Have fun using yum😉

Step 1:

Attach the CD/DVD to VM

Goto VM>> Removable Devices >> CD/DVD(SATA) >> Setting

We Just need to check the connected box and second one is optional if you to connect it automatically when booting is also fine

If Every thing goes fine then we should see the some thing like this posted in screenshot below if not then there is some mistake done while following this article
