Vagrant拒绝以private_network模式连接

Question

我已经将运行VistualBox的Vagrant(1.2.2)VM设置为:private_network,我已经启动了一个Sinatra服务器.但是我无法连接到那个Sinatra实例.然而,VM运行并响应ping.

这是我的Vagrantfile

Vagrant.configure("2") do |config|
    config.vm.box = "precise64"
    config.vm.network :private_network, ip: "192.168.33.10"
end

所以我启动了Vagrant VM并将其添加到其中

prodserv$ vagrant up

所以到这里一切都很好,花花公子.对VM的ping可以正常工作(我还检查过这确实是VM的ip.所以没有流浪汉的ping会导致程序包丢失)

prodserv$ ping 192.168.33.10
PING 192.168.33.10 (192.168.33.10): 56 data bytes
64 bytes from 192.168.33.10: icmp_seq=0 ttl=64 time=0.543 ms
64 bytes from 192.168.33.10: icmp_seq=1 ttl=64 time=0.328 ms

大!现在我在VM上启动服务器

vagrant@precise64:~$ sudo ruby /vagrant/server.rb
== Sinatra/1.4.2 has taken the stage on 4567 for development with backup from Thin
>> Thin web server (v1.5.1 codename Straight Razor)
>> Maximum connections set to 1024
>> Listening on localhost:4567, CTRL+C to stop

这是相应的server.rb

require 'rubygems'
require 'sinatra'

get '/' do
    puts "WOW!"
    'Hello, world!'
end

如果我卷曲从现在客户虚拟机到西纳特拉一切工作正常,"你好,世界!" 将被退回.

vagrant@precise64:~$ curl 'http://localhost:4567'
Hello, world!vagrant@precise64:~$

#and the Sintra/Ruby process gets me this
WOW!
127.0.0.1 - - [23/May/2013 16:06:36] "GET / HTTP/1.1" 200 13 0.0026

但是,如果我尝试从主机卷曲,则连接被拒绝.

prodserv$ curl -v 'http://192.168.33.10:4567'
* About to connect() to 192.168.33.10 port 4567 (#0)
*   Trying 192.168.33.10...
* Connection refused
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

那么这是什么一回事？

Answer 1

你的sinatra正在侦听localhost:4567,而不是0.0.0.0所以它只适用于localhost.
