我知道这是一个非常常见的问题，但我似乎找不到解决方案，而且我对 Node JS 和 Nginx 还不熟悉。
example.com我正在尝试使用 nginx 反向代理在我的网站的 80 端口上运行我的 Node JS 应用程序，我的应用程序在 5000 端口上运行。我搜索了无数论坛，并一步一步地遵循了许多教程，但是当我运行该应用程序并转到时http://example.com，它只是不显示该应用程序，并且在没有index.html文件时显示默认页面（我删除了索引文件以防它产生某种干扰）。
为了防止出现这种情况，我在同一台服务器上托管了另外 2 个域。
其他信息：
- 服务器操作系统：Ubuntu，运行带有文件管理器的 VestaCP
- Node 应用程序的位置：
/home/admin/web/example.com/node-application
它在端口 5000 上运行良好，并且当我运行在端口 80 上监听的应用程序时没有收到错误。
以下是Github 仓库应用程序的所有代码都在这里，但我还将在此处添加 server.js 代码：
服务器.js：
var express = require('express');
var http = require('http');
var path = require('path');
var socketIO = require('socket.io');
var app = express();
var server = http.Server(app);
var io = socketIO(server);
app.set('port', 5000);
app.use('/static', express.static(__dirname + '/static'));
// Routing
app.get('/', function(request, response) {
response.sendFile(path.join(__dirname, '/static/index.html'));
});
// Starts the server.
server.listen(5000, function() {
console.log('Starting server on port 5000');
});
var players = {};
io.on('connection', function(socket) {
socket.on('new player', function() {
players[socket.id] = {
x: 300,
y: 300
};
socket.emit("yoursocketid", socket.id);
});
socket.on('movement', function(data) {
var player = players[socket.id] || {};
if (data.left) {
player.x -=5;
}
if (data.up) {
player.y -= 5;
}
if (data.right) {
player.x += 5;
}
if (data.down) {
player.y += 5;
}
});
socket.on('disconnect', function() {
io.sockets.emit('player disconnected', "player " + socket.id + " disconnected");
delete players[socket.id];
});
socket.on("chat message", function(data) {
console.log("message from " + data.from + ": " + data.message);
io.sockets.emit("new message", data.from + ": " + data.message);
});
socket.on("myusername", function(data) {
players[socket.id].username = data;
});
});
setInterval(function() {
io.sockets.emit('state', players);
}, 1000 / 60);

我也尝试过将服务器块移动/etc/nginx/sites-enabled/default到/etc/nginx/conf.d/thealonegames.com.conf仍然没有用。
我也尝试了 setcap，虽然我知道它不那么安全，但它仍然没有改变任何东西。
我在配置中做错了什么，还是我忘记做了什么？请告诉我可能导致问题的任何原因，这真的很有帮助。谢谢！

我没有资格查看您的配置并告诉您哪里出了问题，但我想提出一个替代方案。我使用“jc21/nginx-proxy-manager”docker 容器通过代理管理多个服务，它确实有效。除非您想成为 nginx 代理配置专家，否则如果您只想以最少的麻烦让它工作，docker 容器是一个很棒的解决方案。它还管理您通过它运行的所有服务的 LetsEncrypt 证书。强烈推荐它。
