Ubuntu搭建DNS

摘自 https://blog.csdn.net/change_on/article/details/78376830

环境

DNS服务器配置

# 更新源, 安装软件
apt update
apt install bind9


# 配置服务器域解析文件, 一个git 一个cd
vi /etc/bind/named.conf.local

zone "git.ls"{
    type master;
file "git.ls";
};
zone "cd.ls"{
    type master;
file "cd.ls";
};


cp /etc/bind/db.local /var/cache/bind/git.ls
cp /etc/bind/db.local /var/cache/bind/cd.ls

vi /var/cache/bind/git.ls
在末尾加：@ IN A 192.168.11.80
vi /var/cache/bind/cd.ls
在末尾加：@ IN A 192.168.11.81

配置/etc/bind/named.conf.options 文件
vi /etc/bind/named.conf.options
在中间加入下面的代码，dns服务器就可以访问外网了
 forwarders {
        223.5.5.5;
  };
allow-query-cache       { any; };
