1、安装bind

[root@localhost ~]# yum -y install bind

2、修改主配置文件

[root@localhost ~]# vi /etc/named.conf 修改第13行为   listen-on port 53 { any; };
修改第21行为   allow-query     { any; };

3、修改区域配置文件

[root@localhost ~]# vi /etc/named.rfc1912.zones ## 域名部分和区域数据文件名zone "test.com" IN {type master;file "test.com.zone";allow-update { none; };
};

3、修改区域数据配置文件

[root@localhost ~]# cd /var/named/
[root@localhost named]# cp -p named.localhost test.com.zone  ## 复制模板名改名
[root@localhost named]# vi test.com.zone   ## 编辑区域数据配置文件## 配置文件如下$TTL 1D
@       IN SOA  @ rname.invalid. (0       ; serial1D      ; refresh1H      ; retry1W      ; expire3H )    ; minimumNS      @A       127.0.0.1
IN MX   5       mail.test.com     ## 邮件记录1
mail IN A       192.168.66.66     ## 邮件记录2
www  IN A       192.168.88.88     
tx   IN CNAME   mail              ## 别名解析
*    IN A       9.9.9.9           ## 泛域名解析

4、关闭系统核心防护并清空防火墙规则

[root@localhost named]# setenforce 0
[root@localhost named]# iptables -F

5、开启域名解析服务

[root@localhost named]# systemctl  start named

6、因为是本地（自己）作为DNS服务器，所以要将添加进host文件中

[root@localhost named]# echo "nameserver 192.168.50.131" > /etc/resolv.conf

7、使用host命令查看解析情况

[root@localhost named]# host test.com
test.com has address 127.0.0.1[root@localhost named]# host www.test.com
www.test.com has address 192.168.88.88[root@localhost named]# host mail.test.com
mail.test.com has address 192.168.66.66[root@localhost named]# host tx.test.com
tx.test.com is an alias for mail.test.com.
mail.test.com has address 192.168.66.66[root@localhost named]# host abc.test.com
abc.test.com has address 9.9.9.9## 解析出来的结果与配置一致！PS：如果提示未找到host命令说明未安装bind-utils，使用yum命令安装即可
[root@localhost named]# yum -y install bind-utils
