node.js - 使用 NGINX 为 node.js 应用程序在端口 80 上提供 HTTP 流量，用于使用虚拟主机在 Amazon EC2 上托管的域

Question

我有 2 个域托管在运行 bitnami wordpress 的 Amazon EC2 上，使用 apache 虚拟主机

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

2. website.com > '/apps/website'

我创建了一个托管在“/apps/website/graph”中的 node.js 图形应用

我希望在 website.com/graph 上访问此应用

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 和 wordpress.com:3000/graph 上运行良好

问题 1:如何让它只在 website.com:3000/graph 上工作？

问题的第二部分是如何使用 nginx 为端口 80 上的 HTTP 流量提供服务以在 website.com/graph 上运行？

我在“/sites-available”中创建了这个“graph”nginx 文件并链接到“/sites-enabled”:

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时它不工作。

问题 2:如何使此 HTTP 流量仅在 website.com/graph 上有效？

我在这里做错了什么或遗漏了什么？我是一名前端设计师，我对服务器端没有什么经验，所以请原谅我的无知:)

Answer 1

@PulledBull我在聊天中一起解决了这个问题。他们有以下 Apache 配置:

<VirtualHost *:80>
  ServerName domain.com
  ServerAlias www.domain.com
  DocumentRoot "/opt/bitnami/apps/wordpress/htdocs"

  Include "/opt/bitnami/apps/wordpress/conf/httpd-app.conf"
</VirtualHost>

<VirtualHost *:80>
  ServerName other.domain
  ServerAlias www.other.domain
  DocumentRoot "/opt/bitnami/apps/is/htdocs"

  ErrorLog "logs/otherdomain-error_log"
  CustomLog "logs/otherdomain-access_log" common
</VirtualHost>

<VirtualHost *:443>
  ServerName domain.com
  ServerAlias www.domain.com
</VirtualHost>

我们通过编辑现有配置而不是使用 NGINX 解决了这个问题。我们将以下行添加到我们希望 Node.js 应用可用的每个虚拟主机:

ProxyPass /traingraph 127.0.0.1:3000

我们只希望/traingraph 可以在 other.domain 上访问，所以我们最终得到了以下配置:

<VirtualHost *:80>
  ServerName domain.com
  ServerAlias www.domain.com
  DocumentRoot "/opt/bitnami/apps/wordpress/htdocs"

  Include "/opt/bitnami/apps/wordpress/conf/httpd-app.conf"
</VirtualHost>

<VirtualHost *:80>
  ServerName other.domain
  ServerAlias www.other.domain
  DocumentRoot "/opt/bitnami/apps/is/htdocs"

  ErrorLog "logs/otherdomain-error_log"
  CustomLog "logs/otherdomain-access_log" common
  ProxyPass /traingraph 127.0.0.1:3000
</VirtualHost>

<VirtualHost *:443>
  ServerName domain.com
  ServerAlias www.domain.com
</VirtualHost>
