2.4. Implementing Server Failover

Procedure 2.3. To Implement Server Failover:

1. Ensure that you are running Red Hat Enterprise Linux 5, 6, or 7. For Red Hat Enterprise Linux 3 or 4, use the latest version of up2date.
2. Manually add the secondary servers to the serverURL and noSSLServerURL settings in the /etc/sysconfig/rhn/up2date configuration file (as root).
3. Add the fully qualified domain names (FQDN) of Red Hat Proxy or Red Hat Satellite immediately after the primary server, separated by a semicolon (;). Your client will attempt to connect to these servers in the order provided here. Include as many servers as necessary. For example:

   serverURL[comment]=Remote server URL
   serverURL=https://satellite.example.com/XMLRPC;
   https://your_secondary.your_domain.com/XMLRPC;
   
   noSSLServerURL[comment]=Remote server URL without SSL
   noSSLServerURL=http://satellite.example.com/XMLRPC;
   http://your_secondary.your_domain.com/XMLRPC;
