DNS 正反向解析

DNS 正反向解析

yum install bind -y #安装dns服务

vi /etc/named.conf #进入dns配置文件修改以下内容 listen-on port 53 { any; }; allow-query { any; };

vi /etc/named.rfc1912.zones: 到最后一行添加以下内容 zone "hello.com" IN { //正向解析 type master; file "hello.zone"; }; zone "80.168.192.in-addr.arpa" IN { //反向解析 type master; file "hello.local"; };

cd /var/named cp -p named.localhost hello.zone //正向解析模板

vi hello.zone $TTL 1D @ IN SOA hello.zone 3040401509@qq.com ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS dns.hello.com. dns IN A 192.168.80.100 IN A 192.168.80.101 ftp IN A 192.168.80.102

cp -p named.localhost hello.local //反向解析模板

vi hello.local

$TTL 1D@ IN SOA hello. 3040401509@qq.com (0 ; serial1D ; refresh1H ; retry1W ; expire3H ) ; minimumNS dns.hello.com.100 IN PTR dns.hello.com.101 IN PTR hello.com.

检查主配置文件语法是否有错误：named-checkconf

systemctl start named 启动服务

netstat -anpt | grep named

![](/etc/sysconfig/network-scripts/ifcfg-ens32

DNS1=192.168.80.100

 > systemctl restart network > nslookup hello.com  > nslookup 192.168.80.100
