Offline package Installation

VishwasR · ‎07-07-2025

I need to install some packages offline, what procedure to follow,

Implementation Plan for Offline Package Installation on RHEL 9

1.Use dnf-utils on a system with internet access to download all required packages and their dependencies from trusted RHEL 9 repositories.

2.Save all downloaded .rpm files to a designated directory /tmp/all-offline-libs

3.Transfer or mount this directory on the target offline system.

4.On the offline system, create a custom YUM repository pointing to the mounted directory by configuring a .repo file.

5.Use microdnf or dnf to install the packages offline from the local repository via a shell script.

This did not work any other way

Download the image into the local system.

Create a mount point directory, example /isomount with permissions 555.

Mount the iso image in the VM using “mount -o loop rhel-8.0-x86_64-dvd.iso /isomount”

Or add an entry in the /etc/fstab as “/home/user/rhel-8.0-x86_64-dvd.iso /isomount iso9660 loop 0 0”

$ mount /isomount
Create a file “/etc/yum.repos.d/rhel8.repo” and copy the below data inside

[InstallMedia-BaseOS]

name=Red Hat Enterprise Linux 8 - BaseOS

metadata_expire=-1

gpgcheck=1

enabled=1

baseurl=file:///isomount/BaseOS/

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[InstallMedia-AppStream]

name=Red Hat Enterprise Linux 8 - AppStream

metadata_expire=-1

gpgcheck=1

enabled=1

baseurl=file:///isomount/AppStream/

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

$ yum clean all

$ yum repolist << We should see the new repos listed here.

Try installing any package, example “yum install -y httpd” it should work.
