安装：

　　yum install bind bind-utils

　　bind是主程序，bind-utils包含一些配置和测试工具

配置：

　　vim /etc/named.conf

options {
        listen-on port 53 { any; };    #允许通过本机那个ip4访问
        listen-on-v6 port 53 { any; };　　#允许通过那个ip6访问
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        recursing-file  "/var/named/data/named.recursing";
        secroots-file   "/var/named/data/named.secroots";
        allow-query     { any; };　　#允许那个外部ip访问

　　vim /etc/named.rfc1912.zones

末尾添加：
zone "yueke.com" IN {　　#正向解析
        type master;
        file "yueke.com.zone";
        allow-update { none; };
};
        

　　cp -a /var/named/named.loopback /var/named/yueke.com.zone

　　vim /var/named/yueke.com.zone
