*以服务器地址120.79.254.2为例，服务器具体地址数值仅为示范所需，并非真实所用地址，如有冒犯，请联系更改。

1. 切换权限

sudo su root

2.安装DNS服务器软件包

yum install bind -y

yum install bind-libs -y

3.配置/etc/named.conf文件

vim /etc/named.conf

修改：

listen-on port 53 { any; };

allow-query { any; };

增加：

zone "uc-knight.top" IN{
type master;
file "uc-knight.top.zone";
};

zone "254.79.120.in-addr.arpa" IN{
type master;
file "254.79.120.zone";
};

4.配置 /var/named/uc-knight.top.zone 文件

vim /var/named/uc-knight.top.zone

$ttl 600

@ IN SOA lance.uc-knight.top. lance.www.uc-knight.top.(
2018060601 10800 3600 604800 38400 )
; Serial Refresh Retry Expire MinumumTTL
; Serial<2^32 Refresh>=Retry*2 Refresh+Retry<Expire
; Expire>=Retry*10
@ IN NS lance.uc-knight.top.
lance.uc-knight.top. IN A 120.79.254.2
@ IN MX 5 www.uc-knight.top.
www.uc-knight.top. IN A 120.79.254.2

5.配置 /var/named/254.79.120.zone 文件

vim /var/named/254.79.120.zone

$ttl 600
@ IN SOA lance.uc-knight.top. lance.www.uc-knight.top.(
2018060601 10800 3600 604800 38400 )
; Serial Refresh Retry Expire MinumumTTL
; Serial<2^32 Refresh>=Retry*2 Refresh+Retry<Expire
; Expire>=Retry*10
@ IN NS lance.uc-knight.top.
2 IN PTR lance.uc-knight.top.

6.启动named服务，并设为开机自启

systemctl start named

systemctl enable named

*7.DNS客户端配置（注意不是服务器端）

Linux: yum install bind-utils -y 然后编辑 vim /etc/resolv.conf

本例中为 nameserver 120.79.254.2

Windows: 本地连接/网络适配器-ipv4协议-手动配置输入dns地址

本例中为使用下面的DNS服务器地址- 120.79.254.
