操作系統(tǒng)版本：

[root@test ~]# cat /etc/issue

Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Kernel r on an m

內(nèi)核：

[root@test ~]# uname -a

Linux test 2.6.9-42.EL #1 Wed Jul 12 23:16:43 EDT 2006 i686 i686 i386 GNU/Linux

[root@test ~]#

需要安裝的軟件：

[root@test ~]# rpm -aq | grep bind

bind-9.2.4-16.EL4

bind-utils-9.2.4-16.EL4

bind-chroot-9.2.4-16.EL4

bind-libs-9.2.4-16.EL4

ypbind-1.17.2-8

[root@test ~]# rpm -aq | grep caching-nameserver

caching-nameserver-7.3-3

[root@test ~]#

1，修改配置文件：

[root@test etc]# pwd

/var/named/chroot/etc

[root@test etc]# vi named.conf

添加如下行到配置文件中

zone "example.com" IN{

type master;

file "example.com.zone";

};

zone "25.172.in-addr.arpa" IN {

type master;

file "example.com.local";

};

2，添加zone文件：

[root@test etc]# cd ../var/named/

[root@test named]# pwd

/var/named/chroot/var/named

[root@test named]# ls

data localdomain.zone localhost.zone named.broadcast named.ca named.ip6.local named.local named.zero slaves

[root@test named]# cp localdomain.zone example.com.zone

[root@test named]# cp named.local example.com.local

[root@test named]#

3，修改example.com.zone文件，在文件末尾添加A記錄：

. IN A 172.25.1.111

bbs IN A 172.25.1.112

第一行是完整寫法，第二行是省略寫法，效果一樣。

4，修改example.com.local文件，在文件末尾添加PTR記錄：

111.1.25.172.IN-ADDR-ARPA IN PTR .

112 IN PTR bbs.example.com.

5，修改這個兩個文件的權(quán)限。

[root@test named]# chmod 644 example.com.*

[root@test named]#

6，啟動named.

[root@test named]# service named start

Starting named: [ OK ]

[root@test named]#

啟動的日志信息：

7, 配置dns客戶機.

[root@test named]# cat /etc/resolv.conf

search example.com

nameserver 172.25.1.114

[root@test named]#

8, 測試：

正向解析可以，逆向解析有問題：

[root@test named]# nslookup

> 172.25.1.111

Server: 172.25.1.114

Address: 172.25.1.114#53

** server can't find 111.1.25.172.in-addr.arpa: NXDOMAIN

>

Server: 172.25.1.114

Address: 172.25.1.114#53

Name:

Address: 172.25.1.111

> exit

[root@test named]#

9，修改反向解析的配置文件，把最后兩行更改為：

111.1 IN PTR .

112.1 IN PTR bbs.example.com.

這個是簡單配置。

重啟named服務(wù)，然后測試就可以了。

[root@test named]# nslookup

> 172.25.1.111

Server: 172.25.1.114

Address: 172.25.1.114#53

111.1.25.172.in-addr.arpa name = .
