CentOS / RHEL 7 : How to setup yum repository using locally mounted DVD

by admin

yum is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories. The post below describes step by step procedure to use a locally mounted RHEL 7 DVD iso as yum repository.

1. Mount the RHEL 7 installation media ISO to some directory. For example /mnt :

# mount -o loop rhel7.iso /mnt

2. Copy the media.repo file from the mounted directory /mnt /etc/yum.repos.d/ and name it as rhel7.repo.

# cp /mnt/media.repo /etc/yum.repos.d/rhel7.repo

3. Give appropriate permissions to the repository file.

# chmod 644 /etc/yum.repos.d/rhel7.repo

4. Modify the repo file and change the parameter gpgcheck=0 to gpgcheck=1 and add below 3 lines to the same file.

enabled=1
baseurl=file:///mnt/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

5. Once you have done all the changes, the final repo file shiould look like below.( Note that – media-id may be different depending on the version of RHEL for which DVD is used)

[InstallMedia]
name=DVD for Red Hat Enterprise Linux 7.3 Server
mediaid=9859238196.834790
metadata_expire=-1
gpgcheck=1
cost=500
enabled=1
baseurl=file:///mnt/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

6. Make sure you clear the related caches by yum clean all and subscription-manager clean once.

# yum clean all
# subscription-manager clean

Verify

Verify if you can list out the packages from the repo you just created.

# yum  --noplugins list
# yum repolist -v
