A Major Improvement in BIND 9 Startup Performance

One of the common complaints we've received over the years about BIND 9 is that large authoritative servers, particularly those with a very large number of small zones, are slow to launch. I've met some DNS operators who expressed a powerful aversion to upgrading their systems, because a shutdown and restart can literally take all day.

If that describes you, I have some good news. There is a simple optimization for BIND 9 that can dramatically improve your startup performance. New versions of BIND are being released soon to take advantage of it.

Bind-DLZ with MySQL

Bind-DLZ with MySQL

DNS management with Bind has traditionally been flat files and slave/master configurations. Bind also has a feature/extension called DLZ — dynamically loaded zones. This feature can be very useful when designing applications that use databases or directories for storage rather than having to design your application to address a filesystem to create resource records or zone files.

In this article, I will explain how to set this up for a configuration where there are thousands of name-based virtual hosts hosted on the same VIP/email infrastructure using the same resource record on a CentOS 5.X system using MySQL to store records. The Bind version is 9.6.0-P1.
