Conducting Satellite-Specific Tasks - Red Hat NETWORK SATELLITE 5.1.1 Installation Manual

Chapter 8. Maintenance
If your original SSL certificate does not take your high-availability solution into account, you may
create a new one with a more appropriate Common Name value now. In this case, you may also
generate a new bootstrap script that captures this new value.
3. After installation, copy the following files from the primary Satellite to the secondary Satellite:
• /etc/rhn/rhn.conf
• /etc/tnsnames.ora
• /var/www/rhns/server/secret/rhnSecret.py
4. Copy and install the server-side SSL certificate RPMs from the primary Satellite to the secondary.
Refer to the Sharing Certificates section of the RHN Client Configuration Guide for precise
instructions. Remember, the Common Name value must represent the combined Satellite solution,
not a single machine's hostname.
If you generated a new SSL certificate during Satellite installation that included a new Common
Name value, copy the SSL certificate RPMs from the secondary to the primary Satellite and
redistribute the client-side certificate. If you also created another bootstrap script, you may use this
to install the certificate on client systems.
5. If you did not create a new bootstrap script, copy the contents of /var/www/html/pub/
bootstrap/ from the primary Satellite to the secondary. If you did generate a new one, copy that
directory's contents to the primary Satellite.
6. Turn off the RHN Task Engine on the secondary Satellite with the following command:
/sbin/service taskomatic stop
You may use custom scripting or other means to establish automatic start-up/failover of the RHN
Task Engine on the secondary Satellite. Regardless, it will need to be started upon failover.
7. Share channel package data (by default located in /var/satellite) between the Satellites over
some type of networked storage device. This eliminates data replication and ensures a consistent
store of data for each Satellite.
8. Make the various Satellites available on your network via Common Name and a method suiting
your infrastructure. Options include round-robin DNS, a network load balancer, and a reverse-proxy
setup.

8.7. Conducting Satellite-Specific Tasks

Using a RHN Satellite Server is quite similar to using the hosted version of Red Hat Network. For
this reason, you should consult the RHN Reference Guide to obtain detailed instructions to standard
tasks, such as editing System Profiles and updating packages. Tasks directly related to managing
custom channels and Errata are covered in the RHN Channel Management Guide. This section seeks
to explain activities available only to Satellite customers.
