1.安装dnsmasq

brew install dnsmasq

2.复制配置文件：

sudo cp /usr/local/opt/dnsmasq/dnsmasq.conf.example /usr/local/etc/dnsmasq.conf

3.然后修改刚刚复制过来的配置文件：/usr/local/etc/dnsmasq.conf

subl  /usr/local/etc/dnsmasq.conf #打开配置文件

修改处：resolv-file=/usr/local/etc/resolv.dnsmasq.conf

            addn-hosts=/etc/dnsmasq.hosts

4.创建/usr/local/etc/resolv.dnsmasq.conf domain SRTwifi nameserver 202.96.134.133 nameserver 202.96.128.68 nameserver 114.114.114.114 nameserver 8.8.8.8 nameserver 172.20.135.1

5.在/etc/dnsmasq.hosts路径下添加你所需要解析的hosts域名和ip即可

6.在/etc/resolv.conf文件下也添加如下内容：

domain SRTwifi

nameserver 202.96.134.133 nameserver 202.96.128.68 nameserver 114.114.114.114 nameserver 8.8.8.8 nameserver 172.20.135.1

7.启动dnsmasq服务：sudo brew services start dnsmasq

清dns缓存：sudo killall -HUP mDNSResponder

8.测试dnsmasq服务是否正常

dig baidu.com 或nslookup baidu.com 127.0.0.1 #强制指定路径到这里去解析（/usr/local/etc/resolv.dnsmasq.conf）

dig baidu.com 或nslookup 127.0.0.1 #表示默认路径下解析(/etc/resolv.conf)

 

9.应用：

如果用到openresty需要resolv一些域名的话，只需在nginx.conf文件里的server里面的location里面添加resolver 127.0.0.1;即可；

location /test{    resolver 127.0.0.1;    default_type 'application/json;charset=utf-8';    content_by_lua_file /Users/xx/workspace/lua.api.kafka/app/producer.lua;}
