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“Bind 9.4.0rc2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 {
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; };
};

};
