8.2. Performing Critical Updates to the Server

Red Hat releases critical updates to Red Hat Satellite in the form of an Erratum.
For Red Hat Satellite systems connected to the Internet, apply these errata updates using the Red Hat Update Agent with Red Hat Network. Since the Red Hat Satellite is subscribed to Red Hat Network during initial installation, run the yum update on the Red Hat Satellite or use the website at to apply the updates.


Apache RPMs do not restart the httpd service upon installation. Conducting a full update of the Red Hat Satellite Server (such as with the command yum update) might cause Apache to fail. To avoid this, make sure to restart the httpd service after upgrading it.
For Red Hat Satellite systems not connected to the Internet, retrieve the packages using a customer account at Then, apply these packages manually according to instructions in the Errata Advisory.


It is very important to read the Errata Advisory before applying any Red Hat Satellite Errata Updates. Some Errata Advisories require additional configuration steps to apply certain Red Hat Satellite updates, especially updates to the database. In such cases, the Advisory contains specific and detailed information about necessary steps required.
If you are attempting to only update the server's Red Hat Network Entitlement Certificate, such as to increase its number of client systems, see Chapter 5, Entitlements for instructions.
