1. 安装bind服务

yum -y install bind

2. 修改named配置文件

• /etc/named.conf

 13         listen-on port 53 { any; };  //修改为any;
 14         listen-on-v6 port 53 { any; };  //修改为any;
 15         directory       "/var/named";
 16         dump-file       "/var/named/data/cache_dump.db";
 17         statistics-file "/var/named/data/named_stats.txt";
 18         memstatistics-file "/var/named/data/named_mem_stats.txt";
 19         recursing-file  "/var/named/data/named.recursing";
 20         secroots-file   "/var/named/data/named.secroots";
 21         allow-query     { any; };  //修改为any;

• /etc/named.rfc1912.zones
  在该文件中添加需要解析的域名，这里解析的分别是 www.rj.com，ftp.rj.com

 12 zone "rj.com" IN {  //正向解析
 13         type master;
 14         file "rj.com.zone";  //文件名后缀可自定义
 15         allow-update { none; };
 16 };
 17 
 18 zone "50.16.172.in-addr.arpa" IN {  //反向解析
 19         type master;
 20         file "50.16.172.local";  //文件名后缀可自定义
 21         allow-update { none; };
 22 };

3. 添加对应的文件

cd /var/named/
cp named.localhost rj.com.zone
cp named.localhost 50.16.172.local

4. 修改正向解析文件

  1 $TTL 1D
  2 @       IN SOA  rj.com. rname.invalid. (
  3                                         0       ; serial
  4                                         1D      ; refresh
  5                                         1H      ; retry
  6                                         1W      ; expire
  7                                         3H )    ; minimum
  8         NS      @
  9         A       127.0.0.1
 10         AAAA    ::1
 11 www     IN A    172.16.50.8
 12 ftp     IN A    172.16.50.8

5. 修改反向解析文件

  1 $TTL 1D
  2 @       IN SOA  rj.com. rname.invalid. (
  3                                         0       ; serial
  4                                         1D      ; refresh
  5                                         1H      ; retry
  6                                         1W      ; expire
  7                                         3H )    ; minimum
  8         NS      @
  9         AAAA    ::1
 10 8       PTR     www.rj.com.
 11 8       PTR     ftp.rj.com.

6. 测试

将测试机器的dns服务器地址填写为centos7地址，使用nslookup测试是否解析成功
