A Red Hat training course is available for Red Hat Satellite

Appendix B. Importing Content ISOs into a Disconnected Satellite

In high security environments where hosts are required to function in a closed network disconnected from the Internet, Satellite Server can provision systems with the latest security updates, errata, and packages. To accomplish this, download the Content ISOs for Red Hat Satellite from the Red Hat Customer Portal and import them into Satellite Server.

Important

This section is not required if your Satellite Server is connected to the Internet.

Download the product ISO from the Red Hat Customer Portal, as follows:

  1. Navigate to Downloads (at the very top of the window) and select Red Hat Satellite.
  2. Open the Content ISOs tab. All products in your subscription are listed here.
  3. Click the link for the product name, such as Red Hat Enterprise Linux 6 Server (x86_64) to download the ISO.
  4. Copy all of Satellite Content ISOs to a directory Satellite can access. This example uses /root/isos.
  5. Create a local directory that are shared through httpd on the Satellite. This example uses /var/www/html/pub/sat-import/.

    # mkdir -p /var/www/html/pub/sat-import/
  6. Mount and recursively copy the contents of the first ISO to the local directory:

    # mkdir /mnt/iso
    # mount -o loop /root/isos/first_iso /mnt/iso
    # cp -ruv /mnt/iso/* /var/www/html/pub/sat-import/
    # umount /mnt/iso
    # rmdir /mnt/iso
  7. Repeat the above step for each ISO until you have copied all the data from the Content ISOs into /var/www/html/pub/sat-import/.
  8. Ensure the SELinux contexts for the directory are correct:

    # restorecon -rv /var/www/html/pub/sat-import/
  9. Satellite Server now contains the content from the Content ISOs. However, Satellite Server needs to point to this location as the CDN URL. In the Satellite Web UI, navigate to Content > Red Hat Subscriptions. .
  10. Click Manage Manifest.
  11. On the Subscription Manifest information screen, select the Actions tab.
  12. Navigate to Red Hat Provider Details. Click the edit icon on the Red Hat CDN URL and change the URL to the Satellite host name with the newly created directory, for example:

    http://server.example.com/pub/sat-import/

  13. Click Save and then upload your manifest using Section 4.1.8, “Importing a Subscription Manifest into Satellite Server”.

Satellite is now acting as its own CDN with the files located in http://server.example.com/pub/sat-import/. This is not a requirement. The CDN can be hosted on a different machine inside the same disconnected network as long as it is accessible to Satellite Server using HTTP.

If your environment changes from disconnected to connected, you can reconfigure a disconnected Satellite to pull content directly from Red Hat Customer Portal:

  1. In the Satellite Web UI, navigate to Content > Red Hat Subscriptions.
  2. Click Manage Manifest.
  3. On the Subscription Manifest information screen, select the Actions tab.
  4. Navigate to Red Hat Provider Details. Click the edit icon on the Red Hat CDN URL and change the URL to the Red Hat CDN URL:

    https://cdn.redhat.com

  5. Click Save

Satellite Server pulls content directly from Red Hat Customer Portal on the next synchronization.
