一、       環境：

Centos-6.6-x64位作業系統，IP地址：210.38.248.7

二、       安裝和配置bind服務：

　　1.      命令：yum install bind

　　2.      配置：

1）  配置/etc/named.conf檔案：

acl ip1{

        210.38.240.0/24;              //定義240網段

};

 

acl ip2{

        210.38.248.0/24;              //定義248網段

};

 

options {

        directory       "/var/named";              //服務安裝目錄

        recursion yes;            //是否開啟DNS遞迴

};

view "first"{

        match-clients {ip1;};   //匹配240網段

        recursion yes;

        zone "." IN {

                type hint;

                file "named.ca";

        };

        zone "a.org" IN {

                type master;

                file "a.org.first";

        };

zone "1.168.192.in-addr.arpa" IN {

                type master;

                file "1.168.192";

        };

};

view "second"{

        match-clients {ip2;};         //匹配248網段

                recursion no;

        zone "." IN {

                type hint;

                file "named.ca";

        };

        zone "a.org" IN {

                type master;

                file "a.org.second";

        };

zone "5.168.192.in-addr.arpa" IN {

                type master;

                file "5.168.192";

        };

};

2）  建立a.org.first和a.org.second檔案並配置：

->建立： touch a.org.first

                    Touch a.org.second

->配置：

配置a.org.first如下:

$TTL 1200

$ORIGIN a.org.

@       IN      SOA     ns1.a.org.      admin.a.org.(

                                        2014091301

                                        6H

                                        30M

                                        15D

                                        3D)

        IN      NS      ns1.a.org.

        IN      NS      ns2.a.org.

        IN      MX 10   mail.a.org.

ns1     IN      A       192.168.1.5

ns2     IN      A       192.168.1.6

mail    IN      A       192.168.1.7

www     IN      A       192.168.1.8

配置a.org.first如下:

$TTL 1200

$ORIGIN a.org.

@       IN      SOA     ns1.a.org.      admin.a.org.(

                                        2014091301

                                        6H

                                        30M

                                        15D

                                        3D)

        IN      NS      ns1.a.org.

        IN      NS      ns2.a.org.

        IN      MX 10   mail.a.org.

ns1     IN      A       192.168.5.5

ns2     IN      A       192.168.5.6

mail    IN      A       192.168.5.7

www     IN      A       192.168.5.8

配置1.168.192如下:

$TTL 86400

@          IN     SOA  ns1.a.org.         admin.a.org.(

                                        2014091301

                                        6H

                                        30M

                                        15D

                                        3D)

              IN     NS              ns1.a.org.

              IN     PTR  a.org.

5            IN     PTR  ns1.a.org.

6            IN     PTR  ns2.a.org.

7            IN     PTR  mail.a.org.

8            IN     PTR  www.a.org

配置5.168.192如下:

$TTL 86400

@          IN     SOA  ns1.a.org.         admin.a.org.(

                                        2014091301

                                        6H

                                        30M

                                        15D

                                        3D)

              IN     NS              ns1.a.org.

              IN     PTR  a.org.

5            IN     PTR  ns1.a.org.

6            IN     PTR  ns2.a.org.

7            IN     PTR  mail.a.org.

8            IN     PTR  www.a.org

 

                           ->拷貝檔案到/var/named目錄：

                                     #cp a.org.* /var/named

                                     #cp 1.168.192 /var/named

                                     #cp 5.168.192 /var/named

3.      重啟：service named restart

三、測試：分別在240/248網段的電腦終端上使用命令：nslookup ns1.a.org(網域名稱)測試，查看解析的IP地址。
