Implementing Server Failover - Red Hat NETWORK 3.7 - CLIENT Configuration Manual

Chapter 2. Client Applications
To configure the Red Hat Update Agent on the client systems connecting to the RHN Proxy Server
or RHN Satellite Server, edit the values of the
/etc/sysconfig/rhn/up2date
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
Warning
The setting in
httpProxy
is used to configure an optional HTTP proxy for the client. With an RHN Proxy Server in place, the
setting must be blank (not set to any value).
httpProxy
Skip this section if you are running Red Hat Enterprise Linux 3 later on the client system.
Note
You must use version 2.7.11 or higher of
new certificates. This RPM should be available in
you run
up2date
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
tions in the
/etc/sysconfig/rhn/rhn_register
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
from a series of RHN Servers. This can be especially helpful in sustaining constant updates where
your primary RHN Proxy Server or RHN Satellite Server may be taken offline.
To use this feature, first ensure you are running the required version of
manually add the secondary servers to the
/etc/sysconfig/rhn/up2date
(FQDN) for the Proxy or Satellite immediately after the primary server, separated by a semicolon (;).
For example:
configuration file (as root). Replace the default Red Hat Network
/etc/sysconfig/rhn/up2date
for the Proxy.
, the Red Hat Update Agent can be configured to seek updates

and
serverURL
does not refer to the RHN Proxy Server. It
on the client systems so they can recognize

configuration file (as root). Replace the default
and
serverURL
noSSLServerURL
on your proxy system after

settings in the

settings in the
