Installing MyDNS And The MyDNSConfig Control Panel On CentOS 5.1
In this tutorial I will describe how to install and configure MyDNS
and MyDNSConfig on CentOS 5.1. MyDNS is a DNS server that uses a MySQL
database as backend instead of configuration files like, for example,
Bind or djbdns. The advantage is that 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. A secondary
nameserver can be easily set up by installing a second instance of
MyDNS that accesses the same database or, to be more redundant, uses
the MySQL master / slave replication features to replicate the data to
the secondary nameserver.
