nginx反向代理到本机nodejs应用时速度很慢

Question

我用nodejs搭了一个网站，但是同网的其他的机器无法访问，我上网查，有人说需要一个web服务器发布出来，所以我本机又搭了nginx进行反向代理到我nodejs上，但是很慢。每次第一次访问都得等好长时间。但是直接访问nodejs的端口就很快。项目很小，不应该，所以我感觉是反向代理哪里设置的不对。求解？

Answer 1

你用nginx设置了这么多HTTPheader做什么？只需要这三个，其他的删掉：proxy_set_headerX-Real-IP$remote_addr;proxy_set_headerHost$host;proxy_set_headerX-Forwarded-For$proxy_add_x_forwarded_for;把这一段也删掉：map$http_upgrade$connection_upgrade{defaultupgrade;''close;}很可能是你设了upgrade的header造成的问题。

Answer 2

在server下增加下面的配置项，看看是否有效果ip_hash;
