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 6.5.0 to 6.5.1.
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 and Restoring Satellite Server and Capsule Server in the Administering Red Hat Satellite guide.
5.1. Updating Satellite Server
Prerequisites
- Ensure that you have synchronized Satellite Server repositories for Satellite, Capsule, and Satellite Tools.
- Ensure each external Capsule and Content Host can be updated by promoting the updated repositories to all relevant Content Views.
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:
Ensure the Satellite Maintenance repository is enabled:
# subscription-manager repos --enable \ rhel-7-server-satellite-maintenance-6-rpms
Ensure
satellite-maintain
is installed and up to date:# yum install rubygem-foreman_maintain
Check the available versions to confirm the next minor version is listed:
# satellite-maintain upgrade list-versions
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 6.5.z
Review the results and address any highlighted error conditions before performing the upgrade.
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.Perform the upgrade:
# satellite-maintain upgrade run --target-version 6.5.z
Check when the kernel packages were last updated:
# rpm -qa --last | grep kernel
If a kernel update occurred since the last reboot, reboot the system:
# reboot
5.2. Updating Capsule Server
Updating Capsule Servers to the Next Minor Version
Procedure
To update Capsule Server, complete the following steps:
On Capsule Server, list the enabled repositories:
# subscription-manager repos --list-enabled
Ensure that only the following repositories are enabled:
rhel-7-server-rpms rhel-7-server-satellite-capsule-6.5-rpms rhel-server-rhscl-7-rpms rhel-7-server-satellite-tools-6.5-rpms rhel-7-server-satellite-maintenance-6-rpms rhel-7-server-ansible-2.6-rpms
For more information about disabling and enabling repositories, see Configuring Repositories in Installing Capsule Server. The
rhel-7-server-satellite-tools-6.5-rpms
repository provides Katello Agent. For more information, see Installing the katello Agent in Installing Capsule Server. The Red Hat Software Collections repository is optional, it is required for the Remote Execution feature.Stop the
satellite-maintain
services:# satellite-maintain service stop
Until BZ#1649764 is resolved, update the
gofer
package:# yum update gofer
Restart goferd.
# systemctl restart goferd
Update all packages:
# yum update
If a kernel update occurs, make a note to reboot after the upgrade is complete. Do not reboot at this point.
Perform the update by running the installer script with the
--upgrade
option.# satellite-installer --scenario capsule --upgrade
If a kernel update occurred during the
yum update
step, reboot the system:# reboot
5.3. Updating Content Hosts
Updating Content Hosts to the Next Minor Version
To Update a Content Host, enter the following commands:
Until BZ#1649764 is resolved, update the
gofer
package:# yum update gofer
Restart goferd:
# systemctl restart goferd
Update all packages:
# yum update
If a kernel update occurs, reboot the system:
# reboot
