MAC 下安装dnsmasq来搭建dns服务器

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.而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.建立/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路径下添加你所须要解析的hosts域名和ip便可

6.在/etc/resolv.conf文件下也添加以下内容：

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 @127.0.0.1 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：

若是用到openresty须要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;便可；

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;
}
