nginx缓慢的每一个第二个请求

我目前正在为我的网站创建一个API，使用nodejs和nginx，我已经为每个nodejs应用程序设置了反向代理我将运行（API，主要，其他的东西..）。nginx缓慢的每一个第二个请求

然而，当我尝试我的API，它会用很长的时间每月的第二个要求，有时超时..

你试过绕过nginx的，并直接连接到你的应用程序看起来像吴？ INX无法连接到上游，我猜是你的应用程序。 – Martin 2014-10-27 15:50:23

是的，我有。我通过设置一个上游变量并使用它来代替http：// localhost：2345 /尝试新的东西。现在一切正常！ :) 我会写一个正确的答案，我会解释我如何解决它！ – andersfylling 2014-10-27 20:14:37

我能够通过上游语句来解决这个问题

如：

upstream nodejs_server { 
    server 192.168.0.67:8080; #ip to nodejs server 
} 

#server config 
server { 
    location /nodejsServer/ { #http://localhost/nodejsServer/ 
     proxy_pass http://nodejs_server; 
    } 
}

参考：http://nginx.org/en/docs/http/ngx_http_upstream_module.html

这个问题可能是由于使用loopback接口（localhost）分别作为目标服务器和nginx的绑定目标，使用真实本地地址解决了我的问题。 – ShadowCode 2017-09-05 09:19:28
