Installing MyDNS And The MyDNSConfig Control Panel On Mandriva 2008.0

In this tutorial I will describe how to install and configure MyDNS and MyDNSConfig on Mandriva 2008.0. 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.

MyDNSConfig is an easy to use web-based interface to MyDNS. MyDNSConfig can create all types of DNS records that are available in MyDNS and adds features like user management and access privileges.

I do not issue any guarantee that this will work for you!

 

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

 

2 Installing The Prerequisites

MyDNSConfig is a web-based interface to MyDNS written in PHP. This requires a webserver with PHP enabled and the MySQL database server. If you have already Apache, PHP and MySQL installed, you may skip this step. We also install phpMyAdmin here so that you have a web interface to the MySQL database in case you need it:

urpmi MySQL MySQL-client phpmyadmin

By default, networking is not enabled in the Mandriva 2008.0 MySQL package. We can change this by commenting out the line skip-networking in /etc/my.cnf:

vi /etc/my.cnf

[...]
# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!
#
#skip-networking
[...]

Afterwards, we start MySQL and Apache:

/etc/init.d/mysqld start
/etc/init.d/httpd start

Create a password for the MySQL user root (replace yourrootsqlpassword with the password you want to use):

mysqladmin -u root password yourrootsqlpassword
mysqladmin -h server1.example.com -u root password yourrootsqlpassword

Now you can direct your browser to http://server1.example.com/phpmyadmin/ or http://192.168.0.100/phpmyadmin/ and log in with the user name root and your new root MySQL password.

 

3 Installing MyDNSConfig

Log in to MySQL and create the database:

mysql -u root -p

CREATE DATABASE mydns;
GRANT SELECT, INSERT, UPDATE, DELETE ON mydns.* TO 'mydns'@'localhost' IDENTIFIED BY 'mydnspassword';
GRANT SELECT, INSERT, UPDATE, DELETE ON mydns.* TO 'mydns'@'localhost.localdomain' IDENTIFIED BY 'mydnspassword';
FLUSH PRIVILEGES;
quit;

Replace the word mydnspassword in the above commands with a password of your choice.

Download MyDNSConfig:

cd /tmp
wget http://mesh.dl.sourceforge.net/sourceforge/mydnsconfig/MyDNSConfig-1.1.0.tar.gz
tar xvfz MyDNSConfig-1.1.0.tar.gz
cd MyDNSConfig-1.1.0

Install MyDNSConfig:

mkdir /usr/share/mydnsconfig
cp -rf interface/* /usr/share/mydnsconfig/
ln -s /usr/share/mydnsconfig/web/ /var/www/html/mydnsconfig

Install the MyDNSConfig MySQL Database:

mysql -u root -p mydns < install/mydnsconfig.sql

The command above asks for a password, please enter the password of the MySQL root user.

Edit the MyDNSConfig configuration; please make sure you fill in the correct database settings:

vi /usr/share/mydnsconfig/lib/config.inc.php

Afterwards, remove the MyDNSConfig installer from the /tmp directory:

cd /tmp
rm -rf MyDNSConfig-1.1.0/
rm -f MyDNSConfig-1.1.0.tar.gz
