Chapter 8. Maintenance

Warning

It is very important to read the Errata Advisory before applying any RHN Satellite Errata Updates.

Additional configuration steps may be required to apply certain RHN Satellite updates, especially

if they involve the database. In such cases, the advisory will contain specific and detailed

information about necessary steps that may be required.

If instead of installing new Satellite packages, you are attempting to update the server's RHN

Entitlement Certificate, such as to increase its number of client systems, refer to Chapter 5,

Entitlements for instructions.

8.3. Backing Up the Satellite

Backing up an RHN Satellite can be done in several ways. Regardless of the method chosen, the

associated database also needs to be backed up. For the Stand-Alone Database, consult your

organization's database administrator. For the Embedded Database, refer to Section 8.4, “Using RHN

DB Control” for a complete description of this process and the options available.

Here are the minimum files and directories Red Hat recommends backing up:

• /rhnsat/ - Embedded Database only (never to be backed up while the database is running - refer

to Section 8.4.2, “Backing up the Database”)

• /etc/sysconfig/rhn/

• /etc/rhn/

• /etc/sudoers

• /etc/tnsnames.ora

• /var/www/html/pub/

• /var/satellite/redhat/1 - custom RPMs

• /root/.gnupg/

• /root/ssl-build/

• /etc/dhcp.conf

• /tftpboot/

• /var/lib/cobbler/

• /var/lib/rhn/kickstarts/

• /var/www/cobbler

• /var/lib/nocpulse/

If possible, back up /var/satellite/, as well. In case of failure, this will save lengthy download

time. Since /var/satellite/ (specifically /var/satellite/redhat/NULL/) is primarily a

duplicate of Red Hat's RPM repository, it can be regenerated with satellite-sync. Red Hat

recommends the entire /var/satellite/ tree be backed up. In the case of disconnected satellites,

/var/satellite/ must be backed up.
