Centos 7 搭建DNS服务器

参考：https://www.cnblogs.com/whjblog/p/17047263.html

1、安装DNS服务

    yum install -y bind bind-utils

2、修改/etc/named.conf配置

options {
listen-on port 53 { any; }; //此处修改为any
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";
recursing-file "/var/named/data/named.recursing";
secroots-file "/var/named/data/named.secroots";
allow-query { any; }; //此处修改为any

3、修改/etc/named.rfc1912.zones配置，在文件末尾加上如下代码

#DNS正向解析
zone "hyqvictory.com" IN {
type master;
file "hyqvictory.com.zone";
allow-update { none; };
};

#DNS反向解析
zone "20.168.192.in-addr.arpa" IN {
type master;
file "hyqvictory.com.local";
allow-update { none; };
};

 

4、进入/var/named/目录，创建hyqvictory.com.zone和hyqvictory.com.local两个文件，名称对应上面的file

hyqvictory.com.zone

$TTL 1D
@ IN SOA @ rname.invalid. (
                                  0 ; serial
                                 1D ; refresh
                                 1H ; retry
                                 1W ; expire
                                 3H ) ; minimum
NS @
A 192.168.20.100
www IN A 192.168.20.100
node1 IN A 192.168.20.101
node2 IN A 192.168.20.102

 

hyqvictory.com.local

$TTL 1D
@ IN SOA @ rname.invalid. (
                               0 ; serial
                              1D ; refresh
                              1H ; retry
                              1W ; expire
                               3H ) ; minimum
NS @
A 192.168.20.100
101 IN PTR node1.hyqvictory.com.
102 IN PTR node2.hyqvictory.com.

 

5、重启named服务

   systemctl start named 

 

   nslookup www.hyqvictory.com

   nslookup node1.hyqvictory.com 

   nslookup node2.hyqvictory.com

   nslookup 192.168.20.100

   nslookup 192.168.20.101

   nslookup 192.168.20.102
