Question

我真的很喜欢Nginx，我不知道如何正确配置nginx，我的项目文件夹是

/Client (react)
/Server (node)
/ (server config)

我之前有这个nginx配置，并且一切正常。

server {
    listen 80;

    server_name IP;

    location / {
        proxy_pass http://IP:3030;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

后来在Cloudflare上，我仅激活 https ，我的网站无法连接到端口：4000上的后端，根据一些研究，我发现我需要更改nginx的配置，这就是Cloudflare指导我创建的内容。

server {
  listen     80;
  listen     443;

  ssl        on;
  ssl_certificate         /root/certificate.pem;
  ssl_certificate_key     /root/key.key;

  server_name    mydomain.org www.mydomain.org;
  access_log     /var/log/nginx/nginx.vhost.access.log;
  error_log      /var/log/nginx/nginx.vhost.error.log;
  location / {   # i just paste everything i had on the previous config here
    proxy_pass https://IP:3030;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
  }
}

因此，基本上，网站已加载，但无法处理对后端的请求。

如果您不知道为什么我有/server文件夹和/文件夹，这是我的server.js文件：

const express = require("express");
const path = require("path");
const app = express();

const port = process.env.PORT || 3030;
app.use(express.static(path.join(__dirname, "client/build")));
app.get("/*.png", (req, res) => {
  console.log(req.params[0]);
  res.sendFile(path.join(__dirname, "client/public/", req.params[0] + ".png"));
});
app.get("/*.jpeg", (req, res) => {
  console.log(req.params[0]);
  res.sendFile(path.join(__dirname, "client/public/", req.params[0] + ".jpeg"));
});

app.get("/*", (req, res) => {
  res.sendFile(path.join(__dirname, "client/build/", "index.html"));
});

app.listen(port, () => console.log(`Listening on port ${port}`));

很抱歉，很长的帖子，但是我对nginx一无所知，我想报道几乎所有的东西。

也许您的后端服务器没有准备好处理SSL请求。您可以让NGINX为您处理该问题，并与您之前未使用SSL的后端进行通信。您可以通过将proxy_pass指令改回http://地址来实现。

server {
  # Other stuff ...
  location / {
     # Comunicate proxy with backend without encryption until you setup SSL on your application...
     proxy_pass http://IP:3030;
     # Other stuff...
  }
}
