ubuntu搭建dns(正反向解析)

首先安装bind9

进入安装目录

查看是否有相应文件

先编辑named.conf.default-zones文件

添加下面两个内容

wyn.com可以自定义，例如xxx.com

240.165.10IP地址和你的电脑IP地址是反的

file对应的文件需要创建

创建文件

编辑文件

内容如下

options {
directory "/var/cache/bind";
listen-on port 53 {127.0.0.1;10.165.240.100; };
allow-transfer { none; };
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.

    // forwarders {
     //      0.0.0.0;
     // };

//========================================================================
// 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
//========================================================================
dnssec-validation auto;

    auth-nxdomain no;    # conform to RFC1035
     listen-on-v6 { any; };

};

最后一步。编辑resolv.conf文件

这里需要设置为自己的IP地址

解析

如果只想解析wyn.com添加最下面那一行

即可
