Implementing Server Failover - Red Hat NETWORK SATELLITE 5.2 - CLIENT Configuration Manual

Chapter 2. Client Applications
sysconfig/rhn/up2date configuration file (as root). Replace the default Red Hat Network URL
with the fully qualified domain name (FQDN) for the RHN Proxy Server or RHN Satellite Server. For
example:
serverURL[comment]=Remote server URL serverURL=https://
your_primary.your_domain.com/XMLRPC noSSLServerURL[comment]=Remote server
URL without SSL noSSLServerURL=http://your_primary.your_domain.com/
XMLRPC
Warning
The httpProxy setting in /etc/sysconfig/rhn/up2date does not refer to the
RHN Proxy Server. It is used to configure an optional HTTP proxy for the client. With
an RHN Proxy Server in place, the httpProxy setting must be blank (not set to any
value).
Skip this section if you are running Red Hat Enterprise Linux 3 or later on the client system.
Note
You must use version 2.7.11 or higher of rhn_register on client systems so they can
recognize new certificates. This RPM should be available in /var/spool/up2date
on your proxy system after running up2date for the Proxy.
To configure the Red Hat Network Registration Client on the client systems connecting to the RHN
Proxy Server or RHN Satellite Server, edit the values of the serverURL and noSSLServerURL
options in the /etc/sysconfig/rhn/rhn_register configuration file (as root). Replace the
default Red Hat Network URL with the fully qualified domain name (FQDN) for the RHN Proxy Server
or RHN Satellite Server. For example:
serverURL[comment]=Remote server URL serverURL=https://
your_proxy_or_sat.your_domain.com/XMLRPC noSSLServerURL[comment]=Remote
server URL without SSL noSSLServerURL=http://
your_proxy_or_sat.your_domain.com/XMLRPC

2.2.4. Implementing Server Failover

Beginning with up2date-4.2.38, the Red Hat Update Agent can be configured to seek updates
from a series of RHN Servers. This can be especially helpful in sustaining constant updates if your
primary RHN Proxy Server or RHN Satellite Server may be taken offline.
To use this feature, first ensure that you are running the required version of up2date. Then manually
add the secondary servers to the serverURL and noSSLServerURL settings in the /etc/
sysconfig/rhn/up2date configuration file (as root). Add the fully qualified domain names (FQDN)
for the Proxy or Satellite immediately after the primary server, separated by a semicolon (;). For
example:
serverURL[comment]=Remote server URL serverURL=https://
your_primary.your_domain.com/XMLRPC; \ https://
