其中有這麼一段描述: In order to configure dnsmasq to act as cache for the host on which it is running, put "HTTP://www.aliyun.com/z ixun/aggregation/11696.html">nameserver 127.0.0.1" in /etc/resolv.conf to force local processes to send queries to dnsm asq. Then either specify the upstream servers directly to dnsmasq using --server options or put their addresses real in another file, say /etc/resolv.dnsmasq and run dnsmasq with the -r /etc/resolv.dnsmasq option.
