自建DNS服务

采用bind9，作为DNS服务。

Debian官方WIKI

安装

apt-get install -y bind9 dnsutils

配置文件

主要的配置文件在下边

options

options {
        directory "/var/cache/bind";

        // IPV4的监听端口和地址，127.0.0.1， localhost只能用于本机使用。
        listen-on port 53 { 10.1.1.10; };
		// 允许那些机器方位DNS，any为所有机器都能访问。
        allow-query { any; };
        // 节省资源，关闭验证
        // 不做互联网认证
        dnssec-validation no;
        dnssec-enable no;
        recursion yes;

        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        // 转发的上级DNS的IP
        forwarders {
                10.1.1.254;
        };

        // 设置允许进行递归查询的ip地址列表,缺省值是允许所有地址进行查询,需要注意的是当设置了不允许递归查询后，如果仍然能够查询部分外部的域名，那是因为dns的缓存在起作用，将缓存清除以后就可以了。
        //allow-recursion { internals; };

        //========================================================================
        // If BIND logs error messages about the root key being expired,
        // you will need to update your keys.  See https://www.isc.org/bind-keys
        //========================================================================

        // ipv6监听
        // listen-on-v6 { any; };
};
