Chapter 5: Configure Servers 53

the example, two servers, acmd1 and acmd2, are configured to accept

round-robin requests.

The addresses on the name server are virtual_acmd1 and virtual_acmd2.

Two virtual hosts have also been created with those names. The first

virtual host uses acmd1 as the primary server and acmd2 as the backup.

The second virtual host uses acmd2 as the primary and acmd1 as the

backup.

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.
