Dns从域名服务器
主机名：ns2.dns.com ip:192.168.200.102
Nameserver 192.168.200.102
Nameserver 192.168.200.101
配置 ：
[root@ns2 Packages]# vim /etc/named.conf
options {
listen-on port 53 { 192.168.200.102; };
// listen-on-v6 port 53 { ::1; };
directory "/var/named";
// dump-file "/var/named/data/cache_dump.db";
// statistics-file "/var/named/data/named_stats.txt";
// memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { any; };
/*
- If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
- If you are building a RECURSIVE (caching) DNS server, you need to enable
recursion.
- If your recursive DNS server has a public IP address, you MUST enable access
control to limit queries to your legitimate users. Failing to do so will
cause your server to become part of large scale DNS amplification
attacks. Implementing BCP38 within your network would greatly
reduce such attack surface

};
检查配置文件：
[root@ns2 Packages]# named-checkconf /etc/named.conf
启动服务查看结果：
[root@ns2 Packages]# /usr/sbin/named -u named #因为是centos7下
[root@ns2 Packages]#
[root@ns2 Packages]# ll /var/named/slaves/
total 8
-rw-r--r--. 1 named named 534 Sep 7 17:53 192.168.200.arpa
-rw-r--r--. 1 named named 444 Sep 7 17:53 dns.com.zone
[root@ns2 Packages]#
修改客户机dns：
[root@client ~]# vim /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.200.102
nameserver 192.168.200. 101
结果：
域名更新 修改日期+1 重启会同步！
