首先安装dnsmasq

sudo apt-get install dnsmasq

修改dnsmasq.conf配置文件

sudo nano -K /etc/dnsmasq.conf

设置IGNORE_RESOLVCONF

sudo nano -K /etc/default/dnsmasq
IGNORE_RESOLVCONF=yes

修改resolv.conf，添加上游DNS服务器

sudo nano -K /etc/resolv.dnsmasq.conf

开启dnsmasq服务

sudo systemctl restart dnsmasq
sudo systemctl enable dnsmasq

测试dnsmasq服务

sudo apt-get install  dnsutils

dig www.sina.cn A @127.0.0.1  grep Query

可以看到第二次请求的时间极大地缩短了
