无法从vagrant VM发出出站HTTP请求

Question

我无法从我设置的Vagrant虚拟机中连接到Internet.

例如,在root用户输入时:

curl http://google.com

它失败并显示以下消息:

curl: (6) Couldn't resolve host 'google.com'

我不确定它是否是防火墙设置,但据我所知,我没有为端口80或任何其他端口创建任何防火墙规则.

这是我的Vagrantfile的相关部分.如果我能提供任何其他信息,请在评论中告诉我:

Vagrant.configure("2") do |config|
  # All Vagrant configuration is done here. The most common configuration
  # options are documented and commented below. For a complete reference,
  # please see the online documentation at vagrantup.com.


  # Let Vagrant manage the hostname at boot
  config.vm.hostname = "devbox"

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # config.vm.network :forwarded_port, guest: 80, host: 8080

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  config.vm.network :private_network, ip: "10.0.0.10"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network :public_network

  # Create a public network with a given hardware address.  You can
  # configure your DHCP server (on your router) to assign a particular IP
  # address to the VM.  Update your hosts file accordingly.
  # config.vm.network :public_network, mac: "0a00251010101"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  #config.vm.synced_folder "vagrant/logs", "/logs",
  #  owner: "root", group: "root"

  # Base box to use with Virtualbox provider
  config.vm.box = "debian-7.0.0-amd64-base"
  config.vm.box_url = "http:/mysite.com/debian-7.0.0-amd64-base.box"

这看起来像DNS配置问题.做一个nslookup google.com,看看结果是什么.

尝试在您的Vagrantfile设置中添加以下块,--natdnshostresolver1以便强制VirtualBox NAT引擎拦截DNS请求并将其转发给主机的解析器

config.vm.provider :virtualbox do |vb|

  vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]

end

BTW:没有vagrant reload,您可以直接查看/etc/resolv.confVM内部,可以手动将其设置为网络的DNS服务器,很可能它会正常工作.
