Red Hat Enterprise Linux 7.3 - Setting up a YUM Repository

Well, I've done this for most other RH-based distros over the years: -

Red Hat Enterprise Linux 6.6 - Creating a local Yum repo - really really fast

CentOS Linux - Setting up Yum

Red Hat Enterprise Linux 6.5 - Creating a local Yum Repository

Red Hat Enterprise Linux 6.3 - Creating a local Yum Repository

Adding a local Yum repository to Red Hat Enterprise Linux 6.2

so here goes for RHEL 7.3: -

Mount the RHEL ISO

mount /dev/cdrom  /mnt

Install the required RPMs

rpm -ivh /mnt/Packages/deltarpm-3.6-3.el7.x86_64.rpm 

rpm -ivh /mnt/Packages/python-deltarpm-3.6-3.el7.x86_64.rpm 

rpm -ivh /mnt/Packages/createrepo-0.9.9-23.el7.noarch.rpm
Install the GPG Key

rpm --import /mnt/RPM-GPG-KEY-redhat-release

Setup the Target Directory

mkdir /var/repo
mkdir /var/repo/rhel72
cd /var/repo/rhel72/

Copy the RPMs from the ISO

cp -R /mnt/Packages/* .

Create the Repository

cd ..
createrepo .

Update YUM to reflect the newly added Respository

mv /etc/yum.repos.d /etc/yum.repos.original

mkdir /etc/yum.repos.d

cd /etc/yum.repos.d/

vi server.repo

inserting: -

[server]
gpgcheck=1
name=rhel72
baseurl=file:///var/repo

Unmount the ISO

umount /mnt

Validate the Repository

yum list

Install an RPM from the Repository

yum install -y telnet

Job done
