安装环境:Linux 2.6.18-92.el5 x86_64
安装软件:bind-9.7.5
1、 bind安装
在压缩包存放的目录下(假设我们要把bind放在/home/目录下)
cd /home/ tar zxvf bind-9.7.5.tar.gz cd bind-9.7.5 ./configure --prefix=/usr/local/bind make depend make make install mkdir -p /usr/local/bind/var/run mkdir -p /usr/local/bind/var/named mkdir -p /usr/local/bind/etc touch /usr/local/bind/etc/named.conf touch /usr/local/bind/etc/rndc.conf ln -sf /usr/local/bind/etc/named.conf /etc/named.conf ln -sf /usr/local/bind/etc/rndc.conf /etc/rndc.conf ln -sf /usr/local/bind/var/named /var/named ln -sf /usr/local/bind/sbin/rndc /usr/sbin/rndc ln -sf /usr/local/bind/sbin/named /usr/sbin/named
2、 bind配置
(1)创建密钥
cd /usr/local/bind
sbin/dnssec-keygen -a hmac-md5 -b 128 -n HOST worldhello.
为bind提供了一种安全机制Transaction Signatures,使用共享密钥进行安全的DNS通知和更新。生成的密钥文件K*****.key,K*****.private。其中*.private文件包含的Key: ******* 即为共享密钥。
(2)创建配置文件:etc/rndc.conf
rndc是远程域名服务控制器。是管理员用来控制域名服务器的应用程序,用于动态加载、停止和配置DNS服务。它的配置文件/etc/rndc.conf内容如下:
key worldhello. { /*共享密钥用于和受控DNS服务器之间完成认证*/ algorithm "hmac-md5"; secret "************************"; /*其中*为上面创建的共享密钥*/ }; options { default-server localhost; /*管理的DNS主机名称,本例为管理本机*/ default-key worldhello. ; }; server localhost { key worldhello. ; };
(3)创建配置文件:/etc/named.conf
named.conf 是域名服务器的主配置文件。zone是配置文件中的最重要的部分,描述了一个授权域名下的域名解析信息。

[root@linux etc]# cd /var/named
建立localhost.zone文件
[root@linux named]#vi localhost.zone
$TTL 86400 $ORIGIN localhost. @ 1D IN SOA @ root ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum 1D IN NS @ 1D IN A 127.0.0.1
建立named.local文件
[root@linux named]#vi named.local
$TTL 86400 @ IN SOA localhost. root.localhost. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS localhost. 1 IN PTR localhost.
dig命令直接生成named.root文件
[root@linux named]#dig > named.root
建立test.com域名正向解析文件
[root@linux named]#vi test.zone
$TTL 86400 $ORIGIN test.com. @ IN SOA ns.test.com. root.test.com.( 2012051600 3600 300 604800 3600) @ IN NS ns.test.com. ns IN A 127.0.0.1 www IN A 192.168.101.206
注明:192.168.101.206为www.test.com机器的ip
建立test.com域名反向解析文件
[root@linux named]#vi test.local
$TTL 86400 @ IN SOA test.com. root.test.com.( 20031001; 7200; 3600; 43200; 86400); @ IN NS test.com. 82 IN PTR dns.test.com.
配置named.conf加如以下代码
[root@linux etc]# vi named.conf
key worldhello. { algorithm "hmac-md5"; secret "************************"; /*其中*为上面创建的共享密钥*/ }; controls { inet 127.0.0.1 allow { localhost; } keys { worldhello.; }; }; options { directory "/var/named"; allow-query { any; }; pid-file "named.pid"; }; zone "." IN { type hint; file "named.root"; }; zone "localhost" IN { type master; file "localhost.zone"; allow-update { none; }; }; zone "0.0.127.in-addr.arpa" IN { type master; file "named.local"; allow-update { none; }; }; zone "test.com" IN { type master; file "test.zone"; allow-update { none; }; }; zone "101.168.192.in-addr.arpa" IN { type master; file "test.local"; allow-update { none; }; };
