nginx 每秒请求一次都很慢

Question

我目前正在为我的网站创建一个 api，使用 nodejs 和 nginx，我已经为我将要运行的每个 nodejs 应用程序设置了反向代理（api、主站点、其他东西......）。

但是，当我尝试我的 api 时，它会在每一秒的请求上使用很长时间，有时会超时..

知道出了什么问题吗？已经有一段时间了，它杀死了我:(

请帮忙，它正在破坏我开发应用程序的时间：/

Answer 1

添加这个是因为这对我有用

https://forum.nginx.org/read.php?15,239760,239760似乎表明您可以通过 proxy_pass 到 127.0.0.1 而不是 localhost 并且请求通过正常

麦克布雷施

一岁了，但我想指出这个问题有一个解决方法。就像 Cruz Fernandez 写的那样，您可以在 proxy_pass 指令上设置 127.0.0.1 而不是 localhost。这可以防止每秒请求 60 秒的延迟。我使用的是 Windows 8.1 和 nginx 1.9.5。

克鲁兹费尔南德斯写道：

您可以使用 127.0.0.1（而不是 proxy_pass 指令中的 localhost）

location /nodejsServer/ {
    proxy_pass http://127.0.0.1:3000/;
}

Answer 2

我能够通过使用上游语句来解决这个问题。

例如。：

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;
    }
}
