MyDNS with MyDNSConfig Control Panel and DNSMasq on Ubuntu 6.10 | HowtoForge - Linux Howtos and Tutorials
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.
Installing MySQL and Apache webserver:
apt-get install libdbd-mysql-perl libdbi-perl libmysqlclient15off libnet-daemon-perl libplrpc-perl mysql-client mysql-client-5.0 mysql-server mysql-common apache2 phpmyadmin libapache2-mod-php5
Remove ads
Set the MySQL root password:
mysqladmin -u root password yourrootsqlpassword
Replace yourrootsqlpassword with a password of your choice.
Installing MyDNSConfig
I will use the MyDNS package from the Ubuntu universe repository. Befor you go to the next steps, please make sure that the universe repository is enabled in /etc/apt/sources.list.
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/mydnsconfig
Install the MyDNSConfig SQL 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:
vi /usr/share/mydnsconfig/lib/config.inc.php
The file should look like this:

Afterwards, remove the MyDNSConfig installer from the /tmp directoy:
cd /tmp
rm -rf MyDNSConfig-1.1.0/
rm -f MyDNSConfig-1.1.0.tar.gz
Installing MyDNS
Now install the MyDNS package from Ubuntu. As we created a database named mydns already which contains all the tables needed for MyDNS, we can choose to not create the database in the following setup.
apt-get install mydns-mysql
-> localhost
-> mydns
-> no
-> mydns
-> mydnspassword
Modify the MyDNS configuration file so that MyDNS will listen also on TCP and allow zone transfers:
vi /etc/mydns.conf
allow-tcp = yes
allow-axfr = yes
The basic installation of MyDNS and MyDNSConfig is now finished. To log in to the MyDNSConfig interface, open a web browser and enter enter the following URL:
http:///mydnsconfig/
Replacewith the IP address of your server.
The default username and password of MyDNSConfig is:
Username: admin
Password: admin
Don't forget to change the password after login under System > Users.
Installing DNSMasq
MyDNS does not contain a DNS resolver that is able to resolve DNS records that MyDNS is not athoritive for. In the next step I will install and configure the DNS resolver and cache DNSMasq to act as a local DNS resolver and configure MyDNS to use DNSMasq to resolve external domains. If you don't want your server to resolve external domains, you can skip this part.
Create a DNS Resolver on IP 127.0.0.1:
apt-get install dnsmasq
This installs the dnsmasq Ubuntu package. Now we will have to edit the DNSMasq and MyDNS configuration files to ensure that both pacakges won't listen on the same port on all IP addresses.
vi /etc/dnsmasq.conf
listen-address=127.0.0.1
no-dhcp-interface=
bind-interfaces
Now edit the mydns.conf file to configure MyDNS to not listen on 127.0.0.1:
vi /etc/mydns.conf
no-listen = 127.0.0.1
recursive = 127.0.0.1
Then edit /etc/resolv.conf:
vi /etc/resolv.conf
and add the following line as first line so that the DNSMasq DNS-Cache is used for all local DNS queries, too:
nameserver 127.0.0.1
