發現異常所在

2017/05/31 19:03:13 [error] 22358#0: *1upstream timed out (110: Connection timed out) while reading response headerfrom upstream, client: 223.223
 
.204.244, server: localhost, request: "GET/platform/totalData HTTP/1.1", upstream:"http://10.163.171.188:94/platform/totalData", host:"rep.jinrongboshi.com", referrer: "http://rep.jinrongboshi.com/page/left.jsp"

問題解決：

location / {

       ...

       proxy_read_timeout 150; #重點

       ...

    }

在nginx.conf的location中新增proxy_read_timeout 150;
