CentOS 6.4安装bind-9.8.2最新版（DNS服务器）

1：使用YUM安装bind

yum install bind

2：配置自动启动

chkconfig named on

3：第一次启动named

rndc-confgen -r /dev/urandom -a
service named start

4：配置vi /etc/named.conf

key "rndc-key" {
    algorithm hmac-md5;
    secret "这里拷贝/etc/rndc.key里的内容";
};
controls {
    inet * port 953
    allow { any; } keys { "rndc-key"; };
};
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
allow-query { any; };
forwarders {114.114.114.114;};

5：添加新域名，配置/etc/named.rfc1912.zones，添加以下代码

zone "fm20.cn" IN {
    type master;
    file "fm20.cn.zone";
    allow-update { none; };
};

6：创建A记录与CNAME记录，新增文件/var/named/fm20.cn.zone

$TTL 1
@ IN SOA localhost. root(1 1 1 1 1)
@ IN NS localhost.
@ IN A 127.0.0.1
