标签：DNS 主服务器设置
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
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 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！
