  • 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?


  • Once you have downloaded a DVD version of your chosen Rhel Version and copied it over to a location on your server.
  • Mount the RHEL installation ISO to a directory like /mnt/disc, e.g.:

    # mkdir -p  /mnt/disc   # mount -o loop RHEL7.1.iso /mnt/disc   

    If you use DVD media , you can mount like below.

    # mkdir -p  /mnt/disc   # mount /dev/sr0  /mnt/disc   
  • 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/disc/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

    vi /etc/yum.repos.d/rhel7dvd.repo   enabled=1   baseurl=file:///mnt/disc/   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release   

    In the end, the new repo file could look like the following

    [InstallMedia]   name=DVD for Red Hat Enterprise Linux 7.1 Server   mediaid=1359576196.686790   metadata_expire=-1   gpgcheck=1   cost=500   enabled=1   baseurl=file:///mnt/disc/   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release   
  • Clear the cache and check whether you can get the packages list from the DVD repo

    # yum clean all       # yum repolist enabled   
  • It should look like the following if no other repository is enabled.
    To avoid any corruption its recommend to disable any non-redhat repositories.
# yum repolist enabled   Loaded plugins: product-id, search-disabled-repos, subscription-manager   This system is not registered to Red Hat Subscription Management.
