1.环境 内网IP:192.168.3.8 系统：Centos7 2.安装

代码语言：javascript复制
yum -y install bind*

3.修改bind配置文件

代码语言：javascript复制
vi /etc/named.conf
options {
    listen-on port 53 { 127.0.0.1; any; };
    #监听任何ip对53端口的请求
     allow-query     { localhost; any; };
     #接收任何来源查询dns记录
#增加一个xls.com域名的解析,解析规则在/var/named/xls.com.zone里
zone "xls.com" IN {
    type master;
    file "xls.com.zone";
};

4.配置解析文件

代码语言：javascript复制
[root@xls named]# cat xls.com.zone
$TTL 1D
@   IN SOA  @ root.xls.com. (
                0   ; serial
                1D  ; refresh
                1H  ; retry
                1W  ; expire
                3H )    ; minimum
NS  @
A         192.168.3.8 ;
www     A             192.168.3.8 ;
@       MX      10    mx.xls.com.     ;
AAAA          ::1

5.启动bind

代码语言：javascript复制
systemctl start named
systemctl enable named

6.修改DNS

代码语言：javascript复制
vi /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.3.8

7.开始测试
