2.5. Implementing Server Failover

Procedure 2.3. To Implement Server Failover:

  1. Ensure that you are running Red Hat Enterprise Linux 5 or 6, or for Red Hat Enterprise Linux 3 or 4, 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;
