Chapter 5. Updating Satellite Server, Capsule Server, and Content Hosts

Use this chapter to update your existing Satellite Server, Capsule Server, and Content Hosts to a new minor version, for example, from 6.8.0 to 6.8.1.

Updates patch security vulnerabilities and minor issues discovered after code is released, and are often fast and non-disruptive to your operating environment.

Before updating, back up your Satellite Server and all Capsule Servers. For more information, see Backing Up Satellite Server and Capsule Server in the Administering Red Hat Satellite guide.

5.1. Updating Satellite Server
Link kopieren

Prerequisites

  • Ensure that you have synchronized Satellite Server repositories for Satellite, Capsule, and Satellite Tools 6.8.
  • Ensure each external Capsule and Content Host can be updated by promoting the updated repositories to all relevant Content Views.
Warning

If you customize configuration files, manually or use a tool such as Hiera, these customizations are overwritten when the installation script runs during upgrading or updating. You can use the --noop option with the satellite-installer script to test for changes. For more information, see the Red Hat Knowledgebase solution How to use the noop option to check for changes in Satellite config files during an upgrade.

Updating Satellite Server to the Next Minor Version

To Update Satellite Server:

  1. Ensure the Satellite Maintenance repository is enabled: 

    # subscription-manager repos --enable \
rhel-7-server-satellite-maintenance-6-rpms
    Copy to Clipboard Toggle word wrap

  2. Ensure that the rubygem-foreman_maintain package that provides satellite-maintain is installed and up to date: 

    # yum install rubygem-foreman_maintain
    Copy to Clipboard Toggle word wrap

  3. Check the available versions to confirm the next minor version is listed: 

    # satellite-maintain upgrade list-versions
    Copy to Clipboard Toggle word wrap

  4. Use the health check option to determine if the system is ready for upgrade. On first use of this command, satellite-maintain prompts you to enter the hammer admin user credentials and saves them in the /etc/foreman-maintain/foreman-maintain-hammer.yml file. 

    # satellite-maintain upgrade check --target-version 6.8.z
    Copy to Clipboard Toggle word wrap

    Review the results and address any highlighted error conditions before performing the upgrade.

  5. Because of the lengthy update time, use a utility such as screen to suspend and reattach a communication session. You can then check the upgrade progress without staying connected to the command shell continuously. For more information about using the screen command, see How do I use the screen command? article in the Red Hat Knowledge Base.

    If you lose connection to the command shell where the upgrade command is running, you can see the logged messages in the /var/log/foreman-installer/satellite.log file to check if the process completed successfully.

  6. Perform the upgrade: 

    # satellite-maintain upgrade run --target-version 6.8.z
    Copy to Clipboard Toggle word wrap

  7. Check when the kernel packages were last updated: 

    # rpm -qa --last | grep kernel
    Copy to Clipboard Toggle word wrap

  8. Optional: If a kernel update occurred since the last reboot, stop the satellite-maintain services and reboot the system: 

    # satellite-maintain service stop
# reboot
    Copy to Clipboard Toggle word wrap

5.2. Updating Disconnected Satellite Server

Prerequisites

  • Before syncing the following repositories, set the download policy to Immediate. This is required because Satellite downloads all packages only during synchronization of repositories with the immediate download policy.

  • Ensure that you have synchronized the following Satellite Server repositories for Satellite, Capsule, and Satellite Tools 6.8:

  • Ensure no Red Hat repositories are enabled by entering the command: 

    # yum repolist
    Copy to Clipboard Toggle word wrap

Updating Disconnected Satellite Server to the Next Minor Version

  1. Create a new configuration file as follows: 

    # vi /etc/yum.repos.d/redhat-local.repo
