使用bind搭建DNS服务器

Posted 2020-10-21

1. 安装bind
   yum install -y bind
   cp /etc/named.conf /etc/named.conf.bak

   /etc/named.conf
   chown named /etc/named.conf
   cd /var/named/
   dig -t NS . > named.ca
   检测配置是否有问题: named-checkconf
   检测正解析: named-checkzone "localhost" /var/named/localhost.zone
   检测反解析: named-checkzone "0.0.127.in-addr.arpa" /var/named/named.local
   rndc-confgen -r /dev/urandom -a // 这一步是生成 rndc.key, 如果没有这个key namd 是启动不了的。
   chown named:named /etc/rndc.key
   /etc/init.d/named start
   netstat -lnp |grep named // 查看一下named进程是否监听了53端口
   首先测试正向解析：dig @127.0.0.1 localhost.
   vim /etc/named.conf
   加入如下配置：
   options {
   directory "/var/named";
   };
   zone "." IN {
   type hint;
   file "named.ca";
   };
   zone "localhost" IN {
   type master;
   file "localhost.zone";
   };
   zone "0.0.127.in-addr.arpa" IN {
   type master;
   file "named.local";
   };

vim localhost.zone //加入
$TTL 86400
@ IN SOA localhost. admin.localhost. (
2013081601
1H
10M
7D
1D
)
@ IN NS localhost.
localhost. IN A 127.0.0.1
vim named.local //加入

$TTL 86400
@ IN SOA localhost. admin.localhost. (
2013081601
1H
10M
7D
1D
)
@ IN NS localhost.
1 IN PTR localhost

接着测试反解析：dig @127.0.0.1 -x 127.0.0.1
