错误：2016/09/21 15:10:02 [error] 18423#0: *61221 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 122.231.110.46, server: localhost, request: "POST /wzptServer/do/otherservice/queryRoadInfo?type=2 HTTP/1.1",
upstream: "http://10.17.56.11:8081/wzptServer/do/otherservice/queryRoadInfo?type=2", host: "localhost", referrer: "http://localhost/"

NGINX反向代理的超时报错，解决方法：
