1. 更改主机名，写/etc/hosts记录
vim /etc/hosts
47.99.116.202           test.com
0.0.0.0           test.com

关闭防火墙
systemctl  disable  firewalld  

关闭selinux
vim  /etc/selinux/config
SELINUX=disabled

2. 在DNS服务器上安装bind软件
yum  -y  install bind

3. 启动DNS服务
systemctl restart named.service
systemctl enable named.service
netstat -anlp | grep named


4. 域名服务器的配置
修改DNS服务的配置文件
vim  /etc/named.conf
```
options {
        listen-on port 53 { localhost; };    # 将127.0.0.1改为本机IP
        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; };               # 将localhost改为any,表示所有人都能对我的DNS服务进行查询
```
添加域的信息写在子配置文件
vim  /etc/named.rfc1912.zones
```
zone "test.com" IN {
        type master;
        file "data/test.com.zone";
};
```
编辑正向解析文件
vim  /var/named/data/test.com.zone
```
$TTL 1D
@       IN SOA  dns.test.com. dns.www.test.com. (
                                         20171224      ; serial 
                                         1D      ; refresh 
                                         1H      ; retry 
                                         1W      ; expire 
                                         3H )    ; minimum 
@                       IN      NS      dns.test.com.
dns.test.com.           IN      A       58.48.186.194
@                       IN      MX 10   mail.www.test.com.
mail.www.test.com.      IN      A       58.48.186.194
www.test.com.           IN      A       58.48.186.194
ftp.test.com.           IN      A       58.48.186.194
```
重启
systemctl  restart  named.service
