MySQL based DNS Server: MyDNS

This tutorial will describe how to install and configure MyDNS, a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. This has the advantage that you can easily use web-based frontends to administrate your DNS records. You could even write your own frontend, e.g. using PHP, to interact with the MyDNS database. MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted! This is a major advantage.

There are multiple web frontends to MyDNS. Of course, you can use phpMyAdmin for the MyDNS administration, or you can use the web frontend that comes with MyDNS (which is not for beginners because it lacks the field descriptions), or you can use MyDNSConfig, a tool written by Author. How to install and configure each of them. read more…

In this document I will use PHP5 as Apache module and PHP4 as CGI, and describe the setup for the Linux distributions Debian Sarge (3.1) and Ubuntu 5.10 (Breezy Badger) read more…

Configure Apache for performance

Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU etc. But, most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on the Linux systems. read more…
