/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.
Backing up only these files and directories would require reinstalling the RHN
Satellite Server ISO RPMs and reregistering the Satellite. In addition, Red
Hat packages would need to be resynchronized using the
satellite-sync
tool. Finally, you would have to reinstall the
/root/ssl-build/\
rhn-org-httpd-ssl-key-pair- MACHINE_NAME-VER-REL .noarch.rpm
.
Another method would be to back up all of the files and directories mentioned above but
reinstall the RHN Satellite Server without reregistering it. During the installation, cancel
or skip the RHN registration and SSL certificate generation sections.
The final and most comprehensive method would be to back up the entire machine. This
would save time in downloading and reinstalling but would require additional disk space
and back up time.
8.4. Using RHN DB Control
RHN Satellite Server with Embedded Database requires a utility for managing that
database. Red Hat provides just such a tool: RHN DB Control . This command line utility
allows you to do everything from make, verify, and restore backups to obtain database
status and restart it when necessary. You must be the oracle user to invoke RHN DB
Control . To begin, switch to the oracle user:
su - oracle
Next, issue the following command:
