在Nginx后面部署带有Node服务器的React应用程序

我创建了一个MERN堆栈应用程序,并成功地将该应用程序部署到AWS上。我使用server/文件夹中的pm2 start index.js,该文件夹正在侦听port 5000,然后在client/文件夹中运行pm2 start --name myapp npm -- start,该文件夹正在port 3000上运行。
这很好用,因为如果我用端口访问我的ec2示例公共URL,我的应用程序就在那里。例如,假设它是5.121.15.32:3000(实际上不是)。
然后我想使用nginx不仅删除端口,而且指向我的域,该域被设置为指向我的ec2示例。

server {
    listen 80;

    server_name mydomain.online mydomain.online;
    root /home/ubuntu/my_app/client/build;

    location /api/ {
        proxy_pass http://127.0.0.1:5000;
        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;
    }

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

下面是我的clients/文件夹中的package.json

server/index.js

require("dotenv").config({ path: "./config.env" });
const express = require("express");
const app = express();
const cors = require("cors");
const connection = require("./db");
const authRoutes = require("./routes/auth");

const dashboardRoutes = require("./routes/dashboard");

// database connection
connection();

// middlewares
app.use(express.json());
app.use(cors());

// routes
app.use("/api/auth", authRoutes);
app.use("/api/dashboard", dashboardRoutes);

const port = process.env.PORT || 5000;
app.listen(port, console.log(`Listening on port ${port}...`));

client/App.js

import { Route, Routes, Navigate } from "react-router-dom";
import Main from "./components/Main";
import Login from "./components/Login";

function App() {
    const user = localStorage.getItem("token");

    return (
        <Routes>
            {user && <Route path="/dashboard/:_id" exact element={<Main />} />}

            <Route path="/login" exact element={<Login />} />

            <Route path="/" element={<Navigate replace to="/login" />} />
        </Routes>
    );
}

export default App;

然而,当我转到http://mydomain.online时,它显示Cannot GET /,我部署的最后一步是使用nginx将我的ec2示例指向我的域,我真的很难做到这一点,有人能帮忙吗?

编辑:请看评论和评论底部的聊天来了解更多细节。这个问题被编辑了几次,更新了一些内容,使我的回答变得无关紧要。
你的Nginx配置只有服务器(端口5000),而没有客户端。你需要代理到这两个,你需要分开的位置。这意味着你还必须调整你的客户端代码,以在生产中在不同的路径上访问服务器。这意味着你可以关闭3000和5000从公共访问,并避免硬编码的IP地址。并使用localhost/0.0.0.0根本不起作用,因为它们将引用客户端计算机。
另外(从注解中),您正在运行WebpackDevServer,它不应该在生产中使用。

server {
    listen 80;

    server_name mydomain.online www.mydomain.online;

    location /api/ {
        proxy_pass http://127.0.0.1:5000;
        # other directives here
    }

    location / {
        proxy_pass http://127.0.0.1:3000;
        # other directives here
    }
}

根据评论编辑:react-scripts start运行Webpack Dev Server,这意味着您需要一个方法来更改allowedHosts(请参阅下面的注解),或者构建应用并静态提供(推荐)。

server {
    listen 80;

    server_name mydomain.online www.mydomain.online;

    location / {
        root /home/ubuntu/my_app/client/build;
        # any other directives
    }

    location /api {
        rewrite ^/api/(.*)$ /$1 break;
        proxy_pass http://127.0.0.1:5000;
        proxy_redirect off;
        # any other directives
    }
}
