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
First we enable the RPMforge repository on our CentOS system as some of the packages that we are going to install in the course of this tutorial are not available in the official CentOS 5.1 repositories:
rpm -Uhv
http://apt.sw.be/packages/rpmforge-r...l5.rf.i386.rpm
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:
yum install httpd mysql-server php php-mysql php-mbstring phpmyadmin
Start MySQL:
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
Then set passwords for the MySQL root account:
mysqladmin -u root password yourrootsqlpassword
mysqladmin -h server1.example.com -u root password yourrootsqlpassword
Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):
vi /etc/httpd/conf.d/phpmyadmin.conf
HTML Code:
#
# Web application to manage MySQL
#
#<Directory "/usr/share/phpmyadmin">
# Order Deny,Allow
# Deny from all
# Allow from 127.0.0.1
#</Directory>
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin
Next we change the authentication in phpMyAdmin from cookie to http:
vi /usr/share/phpmyadmin/config.inc.php
HTML Code:
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]
Then we create the system startup links for Apache and start it:
chkconfig --levels 235 httpd on
/etc/init.d/httpd start
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/sourc...g-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
4 Installing MyDNS
Next we download the mydns-mysql rpm package from
http://mydns.bboy.net/download/ and install it as follows:
wget
http://mydns.bboy.net/download/mydns...1.0-1.i386.rpm
rpm -ivh mydns-mysql-1.1.0-1.i386.rpm
Open the MyDNS configuration file /etc/mydns.conf, fill in the correct database details, allow zone transfers by setting allow-axfr to yes, enable TCP (allow-tcp = yes), and specify a recursive resolver (i.e., a valid nameserver, e.g. from your ISP; e.g. recursive = 213.191.92.86) so that MyDNS can answer queries for domains that it isn't authoritative for:
vi /etc/mydns.conf
HTML Code:
##
## /etc/mydns.conf
## Wed Jan 18 17:18:48 2006
## For more information, see mydns.conf(5).
##
# DATABASE INFORMATION
db-host = localhost # SQL server hostname
db-user = mydns # SQL server username
db-password = mydnspassword # SQL server password
database = mydns # MyDNS database name
# GENERAL OPTIONS
user = nobody # Run with the permissions of this user
group = nobody # Run with the permissions of this group
listen = * # Listen on these addresses ('*' for all)
no-listen = # Do not listen on these addresses
# CACHE OPTIONS
zone-cache-size = 1024 # Maximum number of elements stored in the zone cache
zone-cache-expire = 60 # Number of seconds after which cached zones expires
reply-cache-size = 1024 # Maximum number of elements stored in the reply cache
reply-cache-expire = 30 # Number of seconds after which cached replies expire
# ESOTERICA
log = LOG_DAEMON # Facility to use for program output (LOG_*/stdout/stderr)
pidfile = /var/run/mydns.pid # Path to PID file
timeout = 120 # Number of seconds after which queries time out
multicpu = 1 # Number of CPUs installed on your system
recursive = 213.191.92.86 # Location of recursive resolver
allow-axfr = yes # Should AXFR be enabled?
allow-tcp = yes # Should TCP be enabled?
allow-update = no # Should DNS UPDATE be enabled?
ignore-minimum = no # Ignore minimum TTL for zone?
soa-table = soa # Name of table containing SOA records
rr-table = rr # Name of table containing RR data
soa-where = # Extra WHERE clause for SOA queries
rr-where = # Extra WHERE clause for RR queries
Next, create the system startup links for MyDNS and start MyDNS:
chkconfig --levels 235 mydns on
/etc/init.d/mydns start
Finally, we need to fix the system startup links for MyDNS. MyDNS depends on MySQL, so MyDNS must start after MySQL has started, otherwise it will fail. The default startup links for MyDNS make it start before MySQL which is wrong, so we fix this as follows:
cd /etc/rc.d/rc3.d
mv S52mydns S99mydns
cd /etc/rc.d/rc4.d
mv S52mydns S99mydns
cd /etc/rc.d/rc5.d
mv S52mydns S99mydns
MySQL uses the startup links S64mysql, so renaming the MyDNS startup links from S52mydns to S99mydns makes sure that MyDNS starts after MySQL.
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://<your_ip_address>/mydnsconfig/
Replace <your_ip_address> with the IP address of your server.
The default username and password of MyDNSConfig are:
Username: admin
Password: admin
Don't forget to change the password after login under System > Users
