This can be used to perform the sync process described above, using the dump files in
/var/rhn-
sat-sync
to perform the necessary comparisons and imports. See
Section 6.2.3, “Running the
Import”
for precise steps.
6.4. Inter-Satellite Sync
RHN Satellite 5.3 or greater supports synchronization between two Satellites. This synchronization,
also called
Inter-Satellite Sync
, allows administrators to simplify the process of coordinating content
from one RHN Satellite source to another or several others.
The following are the basic requirements for Inter-satellite Sync.
• At least two RHN Satellite 5.3 or greater servers
• At least one RHN Satellite populated with at least one channel
• Master RHN Satellite SSL certificate available on each of the slave RHN Satellites for secure
connection
6.4.1. Recommended Models for Inter-Satellite Sync
The Inter-Satellite Sync feature for Satellite provides facilities for synchronizing content between
two or more Satellites. The following are some of the more typical uses that show the possibilities of
Inter-Satellite Sync and help guide you in determining how to make the most of this feature in your
environment.
Note
If you are not sure if the Inter-Satellite Sync feature is right for your organization, please
note that you can continue to use RHN Satellite 5.3 or greater in the typical manner.
Installing or upgrading to RHN Satellite 5.3 or greater does not require that you make use
of this feature.
Figure 6.1. Staging Satellite
In this example, the Stage Satellite is used to prepare the content and perform quality assurance
(QA) work — to make sure that packages are fit for production use. After content is approved to go to
production, the Production Satellite will then synchronize the content from the Stage Satellite.
