一、規劃說明：
主機A: 雙網卡
192.168.1.7 --> mydomain.org主域名服務器
192.168.10.7 --> myzone.org主域名服務器，其有兩個子域，為market.myzone.org和develog.myzone.org
主機B：雙網卡
192.168.1.6 --> mydomain.org輔助域名服務器
192.168.10.6 --> market.myzone.org子域名服務器
兩台服務器均有DNS獨立的日志，用以記錄查詢（query_logs）記錄和錯誤（err_logs）記錄，以便於DNS後期管理；本文不過多涉及安全方面的問題。
安裝過程請參照另一篇文章“Bind 9.4.0rc2安裝筆記（一步步學習配置簡易DNS）”。
二、主機A：
1. 主配置文件/etc/named.conf
options { directory "/var/named/"; version "0.0.0"; };
logging { channel dns_errors { file "/var/log/named/err_logs" versions 3 size 10m; severity error; print-category yes; print-severity yes; print-time yes; }; channel dns_queries { file "/var/log/named/query_logs" versions 3 size 10m; severity info; print-category yes; print-severity yes; print-time yes; }; category default { dns_errors; }; category queries { dns_queries; }; };
zone "." { type hint; file "named.ca"; };
zone "localhost" { type master; file "named.local"; };
zone "0.0.127.IN-addr.arpa" { type master; file "named.rev"; };
zone "mydomain.org" { type master; file "mydomain.org.zone"; allow-transfer { 192.168.1.6/32; }; };
zone "myzone.org" { type master; file "myzone.org.zone"; allow-transfer { 192.168.10.0/24; }; };
zone "10.168.192.in-addr.arpa" { type master; file "192.168.10.zone"; allow-transfer { 192.168.10.0/24; }; };
zone "1.168.192.in-addr.arpa" { type master; file "192.168.1.zone"; allow-transfer { 192.168.1.6/32; }; };
key "rndc-key" { algorithm hmac-md5; secret "oKLRLl8BolNj883OX1YcxQ=="; };
controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; # End of named.conf
2.域mydomain.org的正向解析文件/var/named/mydomain.org.zone
$TTL 1D $ORIGIN mydomain.org. @ 1D IN SOA mydomain.org. root.mail.mydomain.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.mydomain.org. IN MX 10 mail.mydomain.org. mydomain.org. IN A 192.168.1.7 #泛域名解析 ns IN A 192.168.1.7 mail IN A 192.168.1.100 www IN CNAME mail ftp IN CNAME mail
3.域mydomain.org的反向解析文件/var/named/192.168.1.zone
$TTL 1D @ 1D IN SOA mydomain.org. root.mail.mydomain.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.mydomain.org. 7 IN PTR marion.org. 7 IN PTR ns.mydomain.org. 100 IN PTR mail.mydomain.org.
4.域myzone.org的正向解析文件/var/named/myzone.org.zone
# more /var/named/myzone.org.zone $TTL 1D $ORIGIN myzone.org. @ 1D IN SOA myzone.org. root.mail.myzone.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.myzone.org. IN MX 10 mail.myzone.org. myzone.org. IN A 192.168.10.7 ns IN A 192.168.10.7 mail IN A 192.168.10.5 www IN CNAME mail ftp IN CNAME mail

$ORIGIN develop.myzone.org. #指明授權的子域develop,和上一種方法稍有不同.
IN NS ns.develop.myzone.org. ns IN A 192.168.10.2
5.域myzone.org的反向解析文件/var/named/192.168.10.zone
$TTL 1D @ 1D IN SOA myzone.org. root.mail.myzone.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.myzone.org. 6 IN PTR ns.market.myzone.org 2 IN PTR ns.develop.myzone.org 7 IN PTR ns.myzone.org. 5 IN PTR mail.myzone.org. 7 IN PTR myzone.org.
三、主機B：
1.named主配置文件/etc/named.conf
options { directory "/var/named/"; version "unknown"; forwarders { 192.168.1.7; }; };
logging { channel dns_errors { file "/var/log/named/err_logs" versions 3 size 10m; severity error; print-category yes; print-severity yes; print-time yes; }; channel dns_queries { file "/var/log/named/query_logs" versions 3 size 10m; severity info; print-category yes; print-severity yes; print-time yes; }; category default { dns_errors; }; category queries { dns_queries; }; };
zone "." { type hint; file "named.ca"; };
zone "localhost" { type master; file "named.local"; };
zone "0.0.127.IN-addr.arpa" { type master; file "named.rev"; };
zone "mydomain.org" { type slave; file "mydomain.org.zone"; masters { 192.168.1.7; }; };
zone "1.168.192.in-addr.arpa" { type slave; file "192.168.1.zone"; masters { 192.168.1.7; }; };
zone "market.myzone.org" { type master; file "market.myzone.org.zone"; };
zone "10.168.192.in-addr.arpa" { type master; file "192.168.10.zone"; };
key "rndc-key" { algorithm hmac-md5; secret "NiBZCqWP0IsvMPuZpUKdog=="; };
controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; # End of named.conf
2.子域market.myzone.org的正向解析文件/var/named/market.myzone.org.zone
$TTL 1D $ORIGIN market.myzone.org. @ 1D IN SOA market.myzone.org. root.mail.market.myzone.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.market.myzone.org. IN MX 10 mail.market.myzone.org. market.myzone.org. IN A 192.168.10.6 ns IN A 192.168.10.6 mail IN A 192.168.10.100 www IN CNAME mail
3.子域market.myzone.org的反向解析文件/var/named/192.168.10.zone
$TTL 1D @ 1D IN SOA myzone.org. root.mail.myzone.org. ( 20070301 1H 15M 1W 1D ) IN NS ns.myzone.org. 6 IN PTR ns.myzone.org. 100 IN PTR mail.myzone.org.
注:輔助域的解析文件將會由區域傳送獲得，不需要手動建立。如果你想要反復嘗試區域傳送的效果，請將TTL值改小。本機的如下所示:
4.域mydomain.org的正向解析文件/var/named/mydomain.org.zone
$ORIGIN . $TTL 86400 ; 1 day mydomain.org IN SOA mydomain.org. root.mail.mydomain.org. ( 20070301 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS ns.mydomain.org. A 192.168.1.7 MX 10 mail.mydomain.org. $ORIGIN mydomain.org. ftp CNAME mail mail A 192.168.1.100 ns A 192.168.1.7 www CNAME mail
5.域mydomain.org的反向解析文件/var/named/192.168.1.zone
$ORIGIN . $TTL 86400 ; 1 day 1.168.192.in-addr.arpa IN SOA mydomain.org. root.mail.mydomain.org. ( 20070301 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS ns.mydomain.org. $ORIGIN 1.168.192.in-addr.arpa. 100 PTR mail.mydomain.org. 7 PTR marion.org. PTR ns.mydomain.org.
四：測試結果
1.主機A：
#nslookup > set type=NS > market.myzone.org Server: 127.0.0.1 Address: 127.0.0.1#53
Non-authoritative answer: market.myzone.org nameserver = ns.market.myzone.org.
Authoritative answers can be found from: ns.market.myzone.org internet address = 192.168.10.6 > myzone.org Server: 127.0.0.1 Address: 127.0.0.1#53
myzone.org nameserver = ns.myzone.org. > mydomain.org Server: 127.0.0.1 Address: 127.0.0.1#53

Non-authoritative answer: myzone.org nameserver = ns.myzone.org.
Authoritative answers can be found from: ns.myzone.org internet address = 192.168.10.7 > market.myzone.org Server: 127.0.0.1 Address: 127.0.0.1#53
