使用NGINX在端口80上为使用虚拟主机的Amazon EC2上托管的域的node.js应用程序提供HTTP流量

Question

我使用apache virualhost在运行bitnami wordpress的Amazon EC2上托管了2个域

wordpres.com>'/ apps / wordpress'
website.com>'/ apps / website'

我在'/ apps / website / graph'中创建了一个node.js图形应用程序

我希望在website.com/graph上访问此应用程序

const express = require('express');
const bodyParser = require('body-parser');
const app = express();


app.use(express.static('public'));
app.use(bodyParser.urlencoded({ extended: true }));
app.set('view engine', 'ejs');

app.get('/graph', function (req, res) {
  res.render('index');
});

app.post('/graph', function (req, res) {
  console.log(req.body.speed + " " + req.body.freq);
  res.render('index');
})

var port = 3000;

app.listen(port, function () {
  console.log('Server Running on port ' + port)
});

服务器在website.com:3000/graph以及wordpress.com:3000/graph上运行良好

问题1：我如何才使它仅在website.com：3000 / graph上运行？

问题的第二部分是如何使用nginx在端口80上提供HTTP流量以在website.com/graph上运行？

我在'/ sites-available'中创建了这个'graph'nginx文件，并在'/ sites-enabled'中链接：

server {
  listen 80;
  server_name website.com;
  location /graph{
    proxy_set_header  X-Real-IP  $remote_addr;
    proxy_set_header  Host       $http_host;
    proxy_pass        http://127.0.0.1:3000/graph;
  }
}

然后我重新启动了nginx，但是当我访问website.com/graph时它没有用。

问题2：如何使此HTTP流量工作并且仅在website.com/graph上工作？

我在这里做错了什么或错过了什么？我是一名前端设计师，我对服务器端的经验很少，所以请原谅无知:)

作为参考，我正在关注这个tutorial。
