Chapter 5: Configure Servers 54
The DNS server is configured for round robin using the following A
records:
Address: The virtual hostnames that customers use to send requests to
your site. (The period following the “.com” in the address is required.)
Time to Live: The number of seconds an address can be cached by
intermediate DNS servers for load balancing. This value should be
relatively brief so that the addresses of non-functioning servers are not
cached by intermediate DNS servers for long periods of time.
Service: Always IN for internet.
Record Type: Always A for address.
IP address: The IP addresses for the virtual hosts that you will use for
each server in the cluster. These are the IP addresses that the DNS will
use to send alternate requests.
With this setup, the domain name server sends messages in a round-
robin fashion to the two virtual hosts indicated by the IP addresses,
causing them to share the request load. Each virtual host has a single
primary server on which it performs its work; the other server is a backup
in case the primary goes down or is taken offline for maintenance.
Depending on your needs, more complicated combinations of DNS
round robin and HP Clustered File System can be used, including cluster
configurations with multiple failover-protected load-balanced servers.
