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:

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 "1.168.192.in-addr.arpa" {
type master;
file "192.168.1.zone";
allow-transfer { 192.168.1.6/32; };
};
key "rndc-key" {

secret "oKLRLl8BolNj883OX1YcxQ==";
};
controls {

allow { 127.0.0.1; } keys { "rndc-key"; };
};
