我有这个 Vagrantfile

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "hashicorp/precise32"
  config.vm.network "forwarded_port", guest: 80, host: 3000
  config.vm.network "private_network", ip: "192.168.33.11"
end

我的目标是为 nodejs 运行一个虚拟机。我已经正确安装了节点。在“vagrant ssh”之后，我创建了一个包含以下内容的文件“index.js”：

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(3000, '127.0.0.1');
console.log('Server running at http://127.0.0.1:3000/');

从 vagrant@precise32:/vagrant$，当我运行“curl localhost:3000”时，我得到“Hello world”。但， ...

我需要做什么，在我的本地机器上打开我的浏览器并获得相同的“Hello world”？

如果我尝试“卷曲”我的虚拟机的 ip，我会得到：

$ curl 192.168.33.11:3000
curl: (7) Failed connect to 192.168.33.11:3000; Connection refused

尝试远程登录：

$ telnet 192.168.33.11:3000
Trying 192.168.33.11:3000...
curl: (7) Failed connect to 192.168.33.11:3000; Connection refused

尝试 curl --verbose 仍然不适用于端口 3000

$ curl --verbose 192.168.33.11:3000
* About to connect() to 192.168.33.11 port 3000 (#0)
*   Trying 192.168.33.11...

* Closing connection 0
curl: (7) Failed connect to 192.168.33.11:3000; Connection refused

与端口 80 完美配合

$ curl --verbose 192.168.33.11

If 192.168.33.11 is the IP of the virtual machine running node, then typically you d load 192.168.33.11:3000 in your local machine. A curl error 7 means the request is blocked in case of a firewall.

虽然是一个老问题，但对于那些在较新版本的 Node/Vagrant 上偶然发现它的人来说，这里有一个解决方案。

似乎 Node 不再需要端口转发才能通过 Vagrant 工作。事实上，当 Node 示例本身在 VM 中的 127.0.0.1 上运行时，没有任何转发端口配置对我有用。

相反，让 Node 服务器在您在 Vagrantfile 中指定的专用网络 ip 上运行。在上面的示例中，这等于listen(3000, '192.168.33.11');。

在 Win 10 和 macOS Mavericks 上的 Node 4.2.6 和 Vagrant 1.8.7 上为我工作。
