In this blog post I''ll show you how to create local RPM packages repository for Oracle Enterprise Linux 7.0. Let's start.
First of all we need connected Linux 7.0 ISO, go to the machine setting and check connected checkbox, under ISO image file choose Linux 7.0 installation file as shown below

with root user

mkdir -p /mnt/cdrom
mount -t iso9660 -o ro /dev/sr0 /mnt/cdrom

mkdir -p /repo
cd /mnt/cdrom/Packages
cp * /repo/

cd /repo
rpm -Uvh deltarpm-3.6-3.el7.x86_64.rpm
rpm -Uvh python-deltarpm-3.6-3.el7.x86_64.rpm
rpm -Uvh createrepo-0.9.9-23.el7.noarch.rpm

createrepo .

mv /etc/yum.repos.d/public-yum-ol7.repo /etc/yum.repos.d/public-yum-ol7.repo.bkp

create rhel_repo.repo file under /etc/yum.repos.d/ and write next parameters

vi /etc/yum.repos.d/rhel_repo.repo

[rhel_repo]
name=repo
baseurl="file:///repo/"
gpgcheck=0
enabled=1

now you can check local repository

yum repolist
