Once the ‘ cdrom‘ mounted, you can verify the files under /mnt/cdrom using ls command. Before creating a local yum repository, insert your CentOS 7 DVD ISO image your CD/DVD drive and mount it using the following commands.įirst, create a empty ‘ cdrom‘ directory under ‘ /mnt/‘ location and mount the ‘ cdrom‘ ( /dev/cdrom is the default name of your device) under ‘ /mnt/cdrom‘ path.

Those who are following CD/DVD method, they must have full RHEL/CentOS 7 DVD ISO (download and burn image to CD/DVD) with them, because we use this image to create a local yum repository.
