[root@server01 named]# cp -a named.localhost lizhip.cn.zone
[root@server01 named]# vim lizhip.cn.zone

6 配置反向解析域文件

[root@server01 named]# cp -a named.loopback 172.16.100.zone
[root@server01 named]# vim 172.16.100.zone

7 指定dns服务器ip

[root@server01 named]# echo nameserver 10.1.1.5 > /etc/resolv.conf

8 语法检测,不报错就ok.

[root@server01 named]# named-checkconf /etc/named.conf 
[root@server01 named]# named-checkconf /etc/named.rfc1912.zones 
[root@server01 named]# named-checkzone ./lizhip.cn.zone ./lizhip.cn.zone 
[root@server01 named]# named-checkzone ./172.16.100.zone ./172.16.100.zone 

9 启动服务

[root@server01 named]# systemctl start named
[root@server01 named]# netstat -tnlp | grep named

10 nslookup测试解析

正向的解析测试：
[root@server01 named]# nslookup nginx.lizhip.cn
Server:     10.1.1.5
Address:    10.1.1.5#53

Name:   nginx.lizhip.cn
Address: 172.16.100.31

[root@server01 named]# nslookup nfs.lizhip.cn
Server:     10.1.1.5
Address:    10.1.1.5#53

Name:   nfs.lizhip.cn
Address: 172.16.100.32

反向的解析测试：

[root@server01 named]# nslookup 172.16.100.33
Server:     10.1.1.5
Address:    10.1.1.5#53

33.100.16.172.in-addr.arpa  name = zabbix.lizhip.cn.

[root@server01 named]# nslookup 172.16.100.250
Server:     10.1.1.5
Address:    10.1.1.5#53

250.100.16.172.in-addr.arpa name = dns.lizhip.cn.
