(6)主服務(wù)器:

主服務(wù)器是給定域的所有信息的授權(quán)來(lái)源。它所裝載的域信息來(lái)自于由域管理員所創(chuàng)建

并在本地維護(hù)的磁盤(pán)文件。

我們用"test.com"作為例子,我們需要五個(gè)基本配置文件:

/etc/named.conf

/var/named/named.ca

/var/named/named.local

/var/named/named.test.com

/var/named/named.172.16.0

(6.1)創(chuàng)建或修改/etc/named.conf:

// generated by named-bootconf.pl

options {

directory "/var/named";

/*

* If there is a firewall between you and nameservers you want

* to talk to, you might need to uncomment the query-source

* directive below. Previous versions of BIND always asked

* questions using port 53, but BIND 8.1 uses an unprivileged

* port by default.

*/

// query-source address * port 53;

};

//

// a PM nameserver config

//

zone '.' {

type hint;

file "named.ca";

};

zone '0.0.127.in-addr.arpa' {

type master;

file "named.local";

};

//there are our primary zone files

zone "test.com" {

type master;

file "named.test.com";

};

zone '0.16.172.in-addr.arpa' {

type master;

file 'named.172.16.0';

};

文件中的zone 'test.com'段是聲明這是用于test.com 域的主服務(wù)器,用于該域的數(shù)據(jù)

從/var/named/named.test.com 文件中裝載。

文件中的zone '0.16.172.in-addr.arpa'段是指向映射IP 地址172.16.0.* 到主機(jī)名的

文件。用于該域的數(shù)據(jù)從/var/named/named.172.16.0 文件中裝載。

(6.2)創(chuàng)建或修改/var/named/named.local

@ IN SOA ns.test.com. root.ns.test.com. (

2000051500 ; Serial

28800 ; Refresh

14400 ; Retry

3600000 ; Expire

86400 ) ; Minimum

IN NS ns.test.com.

1 IN PTR localhost.

注意:在修改named.*文件時(shí)每次存盤(pán)時(shí)要注意增加Serial 值,如使用絕對(duì)域名時(shí)千萬(wàn)別忘了后面帶的'.'。

資源記錄中的@字符轉(zhuǎn)變?yōu)楫?dāng)前的域test.com,IN 表示資源記錄使用TCP/IP 地址,SOA 表示管轄開(kāi)始記錄.ns.test.com. 是這個(gè)域的主DNS 服務(wù)器的標(biāo)準(zhǔn)名稱,在之后是聯(lián)系的

EMAIL 地址,其中@字符必須用'.'代替。

 

(6.3)創(chuàng)建或修改/var/named/named.test.com

@ IN SOA ns.test.com. root.ns.test.com. (

2000051500 ; Serial

28800 ; Refresh

14400 ; Retry

3600000 ; Expire

86400 ) ; Minimum

IN NS ns.test.com.

ns A 172.16.0.1

ns2 A 172.16.0.11

www A 172.16.0.2

ftp CNAME www.test.com.

mail A 172.16.0.3

MX 10 mail.test.com.

(6.4)創(chuàng)建或修改/var/named/named.172.16.0

@ IN SOA ns.test.com. root.ns.test.com. (

2000051500 ; Serial

28800 ; Refresh

14400 ; Retry

3600000 ; Expire

86400 ) ; Minimum

IN NS ns.test.com.

1 IN PTR ns.test.com.

11 IN PTR ns1.test.com.

2 IN PTR www.test.com.

3 IN PTR mail.test.com.

(7)輔服務(wù)器

輔服務(wù)器從主服務(wù)器上獲取域信息的完整拷貝.也能以授權(quán)方式回答有關(guān)域的查詢。我們用'test.com'作為例子,我們需要五個(gè)基本配置文件:

/etc/named.conf

/var/named/named.ca

/var/named/named.local

(7.1)創(chuàng)建或修改/etc/named.conf:

// generated by named-bootconf.pl

options {

directory "/var/named";

/*

* If there is a firewall between you and nameservers you want

* to talk to, you might need to uncomment the query-source

* directive below. Previous versions of BIND always asked

* questions using port 53, but BIND 8.1 uses an unprivileged

* port by default.

*/

// query-source address * port 53;

};

//

// a SM nameserver config

//

zone '.' {

type hint;

file "named.ca";

};

zone '0.0.127.in-addr.arpa' {

type master;

file "named.local";

};

//there are our slave zone files

zone "test.com" {

type slave;

file "named.test.com";

masters {172.16.0.1;};

};

zone '0.16.172.in-addr.arpa' {

type slave;

file 'named.172.16.0';

masters {172.16.0.1;};

};

 

在文件中'masters {172.16.0.1;};'其中的IP 地址是你網(wǎng)絡(luò)中主服務(wù)器的IP 地址。從主服務(wù)器上拷貝/var/named/named.ca 和/var/named/named.local 這兩個(gè)文件。實(shí)際運(yùn)行的服務(wù)器可以是以上其中一種配置,也能同時(shí)包含多種配置,但所有的系統(tǒng)都應(yīng)該運(yùn)行解析器。
