Need to set up yum repository for locally-mounted DVD on Red Hat Enterprise Linux 7 or later


  • Red Hat Enterprise Linux 7


  • How to set up yum repository to use locally-mounted DVD with Red Hat Enterprise Linux (RHEL) 7
  • Would like to upgrade server from RHEL 7.x to RHEL 7.y
  • Have a secure environment that will never be connected to the internet, but still needs to be updated
  • Way to update the packages on server, with no satellite server and servers disconnected from internet
  • Offline patches for Red Hat systems
  • How do I create a local repository in RHEL 7?


Red Hat Enterprise Linux 7

  • Mount the RHEL installation ISO to a directory like /mnt, e.g.:
    # mount -o loop RHEL7.1.iso /mnt
    If you use DVD media , you can mount like below.
    # mount /dev/sr0  /mnt

Red Hat Enterprise Linux 7

  • Copy the media.repo file from the root of the mounted directory to /etc/yum.repos.d/ and set the permissions to 0644 or another similar permissions set:
    # cp /mnt/media.repo /etc/yum.repos.d/rhel7dvd.repo
    # chmod 644 /etc/yum.repos.d/rhel7dvd.repo
  • Edit the new repo file, changing the gpgcheck=0 setting to 1 and adding the following 3 lines
    In the end, the new repo file could look like the following (though the mediaid will be different depending on the version of RHEL):
    name=DVD for Red Hat Enterprise Linux 7.1 Server

  • Clear the related caches by yum clean all and subscription-manager clean using the following:
    # yum clean all
    # subscription-manager clean
  • Check whether you can get the packages list from the DVD repo:
    # yum list
  • If no errors are returned, the following can be used to update:
    # yum update
