主服务器的概念我理解成比如一个公司的网站如何能得到解析，就需要在主服务器上添加区域文件，首先在主服务器上的配置文件中监听端口ip设置好，递归关闭，将根域文件删除或注释掉，建立一个gz.com的区域文件，类型是master,并注意文件路径/var/named/gz..com.zone
[root@server-124 named]# vim /etc/named.conf
options { listen-on port 53 { 192.168.10.11; }; 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; };
recursion no;
dnssec-enable yes;
dnssec-validation yes;
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
pid-file "/run/named/named.pid";
session-keyfile "/run/named/session.key";
};
logging { channel default_debug { file "data/named.run"; severity dynamic; }; };
zone "gz.com" IN { type master; file "/var/named/gz.com.zone"; };
#include "/etc/named.rfc1912.zones"; #include "/etc/named.root.key"; 保存退出，并去建立该文件/var/named/gz.com.zone，默认文件不存在，需要自行建立 [root@server-124 named]# cd /var/named/ [root@server-124 named]# ll 总用量 16 drwxrwx--- 2 named named 23 3月 17 10:20 data drwxrwx--- 2 named named 6 8月 4 2017 dynamic -rw-r----- 1 root named 2281 5月 22 2017 named.ca -rw-r----- 1 root named 152 12月 15 2009 named.empty -rw-r----- 1 root named 152 6月 21 2007 named.localhost [root@server-124 named]# cp named.localhost gz.com.zone [root@server-124 named]# vim gz.com.zone $TTL 1D @ IN SOA server-124.gz.com. tt.qq.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum @ NS server-124.gz.com. server-124 A 192.168.10.11 www A 192.168.10.8 ftp A 192.168.10.10 保存退出，注意这个文件必须让named用户可读 [root@server-124 named]# ll 总用量 20 drwxrwx--- 2 named named 23 3月 17 10:20 data drwxrwx--- 2 named named 6 8月 4 2017 dynamic -rw-r----- 1 root root 272 3月 17 19:29 gz.com.zone [root@server-124 named]# chown named gz.com.zone [root@server-124 named]# systemctl reload named
在客户端将dns指向192.168.10.11，验证： [root@server-125 ~]# nslookup www.gz.com Server: 192.168.10.11 Address: 192.168.10.11#53
Name: www.gz.com Address: 192.168.10.8
[root@server-125 ~]# nslookup ftp.gz.com Server: 192.168.10.11 Address: 192.168.10.11#53
Name: ftp.gz.com Address: 192.168.10.10 成功解析！
