DNS服务器安装部署，The DNS server installation deployment.html一、配置一台DNS缓存服务器 二、配置一个正向解析区域 三、配置一个反向解析区域 四、如何配置DNS主从？ 五、如何配置子域授权？ 六、如何配置forward？ 七、如何配置Bind View？
1、虚拟机操作系统：centos6.7 64bit 2、虚拟机IP地址：10.22.22.1（N01）、10.22.22.2（N02）、10.22.22.11（C01）、10.22.22.12（C02） 3、虚拟化客户端：VMware Workstation 12 Pro 12.1.1 build-3770994
bind：DNS服务器的主程序 bind-libs：提供了bind和bind-utils所依赖的到库文件 bind-utils：提供了bind客户端的程序集合，如dig、host、nslookup等实用工具 bind-chroot：让named运行于jail模式下（jail可以理解为一种更安全的模式）
