1、卸載bind

[root@mail?~]#?rpm?-e?bind-utils

2、安裝bind97-utils?bind97-libs?bind97

[root@mail?~]#?yum?install?bind97?bind97-utils???#bind97-libs依賴于utils

3、啟動dns服務

[root@mail?~]#?service?named?start

4、編寫配置文件和區域數據文件

[root@mail?~]#?vim?/etc/named.conf

//

//?named.conf

//

//?Provided?by?Red?Hat?bind?package?to?configure?the?ISC?BIND?named(8)?DNS

//?server?as?a?caching?only?nameserver?(as?a?localhost?DNS?resolver?only).

//

//?See?/usr/share/doc/bind*/sample/?for?example?named?configuration?files.

//

options?{

directory???????"/var/named";

dump-file???????"/var/named/data/cache_dump.db";

statistics-file?"/var/named/data/named_stats.txt";

memstatistics-file?"/var/named/data/named_mem_stats.txt";

allow-query?????{?localhost;?};

recursion?yes;

dnssec-enable?yes;

dnssec-validation?yes;

dnssec-lookaside?auto;

/*?Path?to?ISC?DLV?key?*/

bindkeys-file?"/etc/named.iscdlv.key";

};

logging?{

channel?default_debug?{

file?"data/named.run";

severity?dynamic;

};

};

zone?"."?IN?{

type?hint;

file?"named.ca";

};

include?"/etc/named.rfc1912.zones";

[root@mail?~]#?vim?/etc/named.rfc1912.zones

在里面添加下面的內容：

zone?"lsq.com"?IN?{

type?master;

file?"lsq.com.zone";

allow-update?{?none;?};

allow-transfer?{?none;?};

};

zone?"25.16.172.in-addr.arpa"?IN?{

type?master;

file?"172.16.25.zone";

allow-update?{?none;?};

allow-transfer?{?none;?};

};

配置區域數據文件：

[root@mail?~]#?cd?/var/named

[root@mail?named]#?vim?lsq.com.zone

$TTL?600

@???????IN??????SOA?????ns.lsq.com.?????admin.lsq.com.?(

2013050401

2H

10M

3D

1D?)

IN??????NS??????ns

IN??????MX?10???mail

ns??????????????IN??????A???????172.16.25.1

mail????????????IN??????A???????172.16.25.1

[root@mail?named]#?vim?172.16.25.zone

$TTL?600

@???????IN??????SOA?????ns.lsq.com.?????admin.lsq.com.?(

2013050401

2H

10M

3D

1D?)

IN??????NS??????ns.lsq.com.

1???????????????IN??????PTR?????ns.lsq.com.

1???????????????IN??????PTR?????mail.lsq.com.

5、檢查語法錯誤并重啟服務

[root@mail?named]#?named-checkconf

[root@mail?named]#?named-checkzone?"lsq.com"?lsq.com.zone

zone?lsq.com/IN:?loaded?serial?2013050401

OK

[root@mail?named]#?named-checkzone?"25.16.172.in-addr.arpa"?172.16.25.zone

zone?25.16.172.in-addr.arpa/IN:?loaded?serial?2013050401

OK

[root@mail named]# chgrp named lsq.com.zone 172.16.25.zone [root@mail named]# chmod 640 lsq.com.zone 172.16.25.zone

[root@mail?named]#?service?named?restart

Stopping?named:????????????????????????????????????????????[??OK??]

Starting?named:????????????????????????????????????????????[??OK??]

6、解析A記錄

[root@mail?named]#?dig?-t?A?mail.lsq.com?@172.16.25.1

;?<<>>?DiG?9.7.0-P2-RedHat-9.7.0-6.P2.el5_7.4?<<>>?-t?A?mail.lsq.com?@172.16.25.1

;;?global?options:?+cmd

;;?Got?answer:

;;?flags:?qr?aa?rd?ra;?QUERY:?1,?ANSWER:?1,?AUTHORITY:?1,?ADDITIONAL:?1

;;?QUESTION?SECTION:

;;?WHEN:?Sun?Mar?31?02:19:09?2013

;;?MSG?SIZE??rcvd:?79

解析反向記錄

[root@mail?named]#?dig?-x?172.16.25.1?@172.16.25.1

;?<<>>?DiG?9.7.0-P2-RedHat-9.7.0-6.P2.el5_7.4?<<>>?-x?172.16.25.1?@172.16.25.1
