Installing MyDNS And The MyDNSConfig Control Panel On CentOS 5.1 > 리눅스 Tip

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

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-release/rpmforge-release-0.3.6-1.el5.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

#
#  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

[...]
/* 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/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

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