MyDNS是一種以MySQL資料庫為後台的DNS伺服器，它使用數據記錄的格式替代配置文件格式的傳統DNS伺服器。例如：BIND。MyDNS伺服器的安裝配置和管理更加簡單容易實現 ，而且更容易理解。與傳統和基於配置文件的DNS伺服器相比，初學者更能快速入門。MyDNS從MySQL資料庫中讀取記錄，當記錄或區域增加、修改、刪除的時候不用重新啟動、載入伺服器。MyDNSConfig是使用WEB的MyDNS配置介面，它可以創建所有類型的MyDNS記錄。
步驟：
1。配置網路介面。
在這裡我的電腦主機名為 "wkg.com",IP地址是192.168.1.102。這是個人的設置，請依照你的實際情況進行設置。
2。配置軟體環境。
MyDNSConfig 是基於PHP的基礎上開發的。所以你的伺服器一定要能支持PHP和MySQL才行。它要用到 Apache PHP和 MySQL 。（如果你已經安裝和配置好了它們的話可以跳過這一步 ）在這裡你也要安裝 phpMyAdmin來管理MySQL。
2.1：安裝各種軟體：使用yum命令來安裝既可以解決依賴性問題，也可以得到更新版本的軟體。
# yum install httpd mysql-server php php-mysql php-mbstring phpMyAdmin
2.2：啟動MySQL資料庫(start mysql database)
# chkconfig --levels 235 mysqld on //讓MySQL在伺服器啟動時自動啟動
# /etc/init.d/mysqld start
2.2：設置MySQL 的root 用戶密碼
# mysqladmin -u root password yourrootsqlpassword
# mysqladmin -h wkg.com -u root password yourrootsqlpassword
2.3: 現在我們來配置 phpMyAdmin。修改Apache配置文件，允許 phpMyAdmin能通過別的主機訪問，不是只能在localhost可以訪問。（註銷掉）
gedit /etc/httpd/conf.d/phpMyAdmin.conf (也可以用vi 編輯器來編輯）
修改後的phpMyAdmin.conf 如下：
[table=98%][tr][td] # phpMyAdmin - Web based MySQL browser written in php
#
# Allows only localhost by default
#
# But allowing phpMyAdmin to anyone other than localhost should be considered
# dangerous unless properly secured by SSL
Alias /phpMyAdmin /usr/share/phpMyAdmin
#
# order deny,allow
# deny from all
# allow from 127.0.0.1
#
# This directory does not require access over HTTP - taken from the original
# phpMyAdmin upstream tarball
#
Order Deny,Allow
Deny from All
Allow from None
# This configuration prevents mod_security at phpMyAdmin directories from
# filtering SQL etc. This may break your mod_security implementation.
#
#
#
# SecFilterInheritance Off
#
#[/td][/tr][/table]
2.4：創建啟動項和啟動Apache
# chkconfig --levels 235 httpd on
# /etc/init.d/httpd start
現在可以在瀏覽器中打開：http://wkg.com/phpMyAdmin/ 或者 http://192.168.1.102/phpMyAdmin/ 使用你的新 root MySQL密碼登陸進去。
3 安裝MyDNSConfig (Installing MyDNSConfig)3.1 登錄MySQL和創建資料庫，創建資料庫用戶和授權
＃ mysql -u root -p
mysql> CREATE DATABASE mydns;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mydns.* TO 'mydns'@'localhost' IDENTIFIED BY 'mydnspassword';
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mydns.* TO 'mydns'@'localhost.localdomain' IDENTIFIED BY 'mydnspassword';
//以上兩條語句的作用是創建用戶並授權。
mysql> FLUSH PRIVILEGES;
mysql> quit;
註：mydnspassword是你新建的MySQL用戶的密碼，請根據自己的實際情況設置。
3.2 下載和安裝 MyDNSConfig：
＃ cd /tmp
＃ wget http://mesh.dl.sourceforge.net/s ... Config-1.1.0.tar.gz
＃ tar xvfz MyDNSConfig-1.1.0.tar.gz
＃ cd MyDNSConfig-1.1.0
＃ mkdir /usr/share/mydnsconfig
＃ cp -rf interface/* /usr/share/mydnsconfig/
＃ ln -s /usr/share/mydnsconfig/web/ /var/www/html/mydnsconfig
3.3安裝 MyDNSConfig MySQL Database（在上面的基礎上）
＃ mysql -u root -p mydns < install/mydnsconfig.sql
會提示輸入用戶密碼。輸入你的MySQL root 用戶密碼。即可完成對應資料庫的人創建。
3.4編輯MyDNSConfig的配置文件
gedit /usr/share/mydnsconfig/lib/config.inc.php

3.5完成上面的設置之後從 /tmp 目錄中刪除MyDNSConfig
# cd /tmp
# rm -rf MyDNSConfig-1.1.0/
# rm -f MyDNSConfig-1.1.0.tar.gz
4:安裝 MyDNS
4.1 從 http://mydns.bboy.net/download/ 下載 mydns-mysql RPM包 並安裝它
＃ wget http://mydns.bboy.net/download/mydns-mysql-1.1.0-1.i386.rpm
＃ rpm -ivh mydns-mysql-1.1.0-1.i386.rpm
4.2 打開MyDNS 配置文件 /etc/mydns.conf,相對應的資料庫做一些調整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)
＃ gedit /etc/mydns.conf
修改之後為如下：
[table=95%][tr][td] ##
## /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[/td][/tr][/table]
下一步創建啟動對象，讓系統啟動時啟動MyDNS.
# chkconfig --levels 235 mydns on
# /etc/init.d/mydns start
4.3用瀏覽器打開URL：http:///mydnsconfig/
然後用默認的用戶名和密碼進行登錄，默認的用戶名和密碼是admin。可以在 System > Users修改你的用戶密碼。
