How to create yum local repository in RHEL7/CentOS7 using ISO image

If you have a fresh installation of red hat enterprise linux 7, you cannot access yum commands by default. Also you have to subscribe redhat to get repository updates from the internet.

I explained below how to make local yum repository and map using iso image in the cdrom.

First mount cdrom to a specific folder,

[akila@localhost ~]# mount /dev/cdrom  /<yourDirectory>

Then create and start editing new repo using below command, RHEL_7_Disc.repo is your local .repo file

[akila@localhost ~]# vi /etc/yum.repos.d/RHEL_7_Disc.repo

Then add below command in the file,

[RHEL_7_Disc]

name=RHEL_7_x86_64_Disc

baseurl="file:///<DirectoryYou mount your cdrom>/"

gpgcheck=0

That’s all. You have successfully created local yum repository in your machine.

Check repolist using below command, and you will see below result,

[root@lolfusionlbone ~]# yum repolist

Loaded plugins: langpacks, product-id, subscription-manager

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

repo id                          repo name                                status

RHEL_7_Disc                      RHEL_7_x86_64_Disc                       4,305

repolist: 4,305

Just try to install telnet using yum command to test the installation of repository by using below command,

[root@lolfusionlbone ~]# yum install telnet
