配置DNS辅助域名和子域名服务器

一、规划说明：

主机A:双网卡

192.168.1.7??>mydomain.org主域名服务器

192.168.10.7??>myzone.org主域名服务器,其有两个子域,为market.myzone.org和develog.myzone.org

主机B：双网卡

192.168.1.6??>mydomain.org辅助域名服务器

192.168.10.6??>market.myzone.org子域名服务器

两台服务器均有DNS独立的日志,用以记录查询（query_logs）记录和错误（err_logs）记录,以便于DNS后期管理；本文不过多涉及安全方面的问题。

安装过程请参照另一篇文章“Bind9.4.0rc2安装笔记（一步步学习配置简易DNS）”。

　　二、主机A：

1.主配置文件/etc/named.conf

options{directory"/var/named/";version"0.0.0";};logging{channeldns_errors{file"/var/log/named/err_logs"versions3size10m;severityerror;print-categoryyes;print-severityyes

2.域mydomain.org的正向解析文件/var/named/mydomain.org.zone


$TTL1D$ORIGINmydomain.org.@1DINSOAmydomain.org.root.mail.mydomain.org.(200703011H15M1W1D)INNSns.mydomain.org.INMX10mail.mydomain.org.mydomain.org.INA192.168.1.7#泛域名解析nsINA192.168.1.7mailINA192.168.1.100wwwINCNAMEmailftpINCNAMEmail
3.域mydomain.org的反向解析文件/var/named/192.168.1.zone


$TTL1D@1DINSOAmydomain.org.root.mail.mydomain.org.(200703011H15M1W1D)INNSns.mydomain.org.7INPTRmarion.org.7INPTRns.mydomain.org.100INPTRmail.mydomain.org.
4.域myzone.org的正向解析文件/var/named/myzone.org.zone


#more/var/named/myzone.org.zone$TTL1D$ORIGINmyzone.org.@1DINSOAmyzone.org.root.mail.myzone.org.(200703011H15M1W1D)INNSns.myzone.org.INMX10mail.myzone.org.myzone.org.INA192.168.10.7nsINA192.168.10.7mailINA192.168.10.5wwwINCNAMEmailftpINCNAMEmailmarketINNSns.market#指明授权的子域marketns.marketINA192.168.10.6$ORIGINdevelop.myzone.org.#指明授权的子域develop，和上一种方法稍有不同.INNSns.develop.myzone.org.nsINA192.168.10.2
5.域myzone.org的反向解析文件/var/named/192.168.10.zone


$TTL1D@1DINSOAmyzone.org.root.mail.myzone.org.(200703011H15M1W1D)INNSns.myzone.org.6INPTRns.market.myzone.org2INPTRns.develop.myzone.org7INPTRns.myzone.org.5INPTRmail.myzone.org.7INPTRmyzone.org.

三、主机B：

1.named主配置文件/etc/named.conf


options{directory"/var/named/";version"unknown";forwarders{192.168.1.7;};};logging{channeldns
2.子域market.myzone.org的正向解析文件/var/named/market.myzone.org.zone


$TTL1D$ORIGINmarket.myzone.org.@1DINSOAmarket.myzone.org.root.mail.market.myzone.org.(200703011H15M1W1D)INNSns.market.myzone.org.INMX10mail.market.myzone.org.market.myzone.org.INA192.168.10.6nsINA192.168.10.6mailINA192.168.10.100wwwINCNAMEmail
3.子域market.myzone.org的反向解析文件/var/named/192.168.10.zone


$TTL1D@1DINSOAmyzone.org.root.mail.myzone.org.(200703011H15M1W1D)INNSns.myzone.org.6INPTRns.myzone.org.100INPTRmail.myzone.org.
注:辅助域的解析文件将会由区域传送获得,不需要手动建立。如果你想要反复尝试区域传送的效果,请将TTL值改小。本机的如下所示:

4.域mydomain.org的正向解析文件/var/named/mydomain.org.zone


$ORIGIN.$TTL86400;1daymydomain.orgINSOAmydomain.org.root.mail.mydomain.org.(20070301;serial3600;refresh(1hour)900;retry(15minutes)604800;expire(1week)86400;minimum(1day))NSns.mydomain.org.A192.168.1.7MX10mail.mydomain.org.$ORIGINmydomain.org.ftpCNAMEmailmailA192.168.1.100nsA192.168.1.7wwwCNAMEmail
5.域mydomain.org的反向解析文件/var/named/192.168.1.zone
