如何调试"Vagrant无法转发此VM上的指定端口"消息

Question

我正在尝试启动Vagrant实例并收到以下消息:

Vagrant cannot forward the specified ports on this VM, since they
would collide with another VirtualBox virtual machine's forwarded
ports! The forwarded port to 4567 is already in use on the host
machine.

To fix this, modify your current projects Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:

  config.vm.forward_port 80, 1234

我打开了VirtualBox,但此刻我没有任何运行的盒子,所以我很难过.如何确定哪个进程正在侦听4567？有没有办法列出我机器上运行的所有Vagrant盒子？

谢谢,凯文

Answer 1

您可以通过运行查看计算机上正在运行的vagrant实例

$ vagrant global-status
id       name    provider   state   directory
----------------------------------------------------------------------
a20a0aa  default virtualbox saved   /Users/dude/Downloads/inst-MacOSX
64bc939  default virtualbox saved   /Users/dude/svn/dev-vms/ubuntu14
a94fb0a  default virtualbox running /Users/dude/svn/dev-vms/centos5

如果您没有看到任何正在运行的虚拟机,那么您的冲突就不是流浪汉(流浪者知道).接下来要做的是启动VirtualBox UI,并检查它是否有任何实例在运行.如果您不想运行UI,您可以:

ps -ef |grep VBox

如果您正在运行VirtualBox实例,则它们应包含在该输出中.您应该能够杀死其输出中包含VirtualBox的进程.一个问题是这些过程中的一个似乎存在以进行保持活动.刚刚杀掉最高的VirtualBox进程.如果您正在运行VirtualBox映像,但vagrant不知道它,则可能已手动删除了一些Vagrant目录,这意味着Vagrant将丢失对该实例的跟踪.

注意,你的Vagrantfile 不是唯一一个在启动Vagrant盒子/实例时使用的.

当你得到这个:

~/dev/vagrant user$ vagrant reload
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 8001 is already in use
on the host machine.

To fix this, modify your current projects Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:

  config.vm.network :forwarded_port, guest: 8001, host: 1234

Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding.
~/dev/vagrant user$ 

您实际上不仅使用〜/ dev/vagrant中的Vagrantfile,还使用通常位于此处的"box"分发.box文件中的Vagrant文​​件:

~/.vagrant.d/boxes/trusty/0/virtualbox/Vagrantfile

如果你看一下它,你会发现它有很多默认的端口映射:

$ cat ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile
$script = <<SCRIPT
bzr branch lp:jujuredirector/quickstart /tmp/jujuredir
bash /tmp/jujuredir/setup-juju.sh
SCRIPT

Vagrant.configure("2") do |config|
  # This Vagrantfile is auto-generated by 'vagrant package' to contain
  # the MAC address of the box. Custom configuration should be placed in
  # the actual 'Vagrantfile' in this box.

  config.vm.base_mac = "080027DFD2C4"
  config.vm.network :forwarded_port, guest: 22, host: 2122, host_ip: "127.0.0.1"
  config.vm.network :forwarded_port, guest: 80, host: 6080, host_ip: "127.0.0.1"
  config.vm.network :forwarded_port, guest: 8001, host: 8001, host_ip: "127.0.0.1"
  config.vm.network "private_network", ip: "172.16.250.15"
  config.vm.provision "shell", inline: $script

end

# Load include vagrant file if it exists after the auto-generated
# so it can override any of the settings
include_vagrantfile = File.expand_path("../include/_Vagrantfile", __FILE__)
load include_vagrantfile if File.exist?(include_vagrantfile)

因此,请继续编辑此文件以删除有问题的冲突转发端口:

  config.vm.network :forwarded_port, guest: 22, host: 2122, host_ip: "127.0.0.1"
  config.vm.network :forwarded_port, guest: 80, host: 6080, host_ip: "127.0.0.1"
  # config.vm.network :forwarded_port, guest: 8001, host: 8001, host_ip: "127.0.0.1"

通过:

~/dev/vagrant user$ cp ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile.old
~/dev/vagrant user$ vi ~/.vagrant.d/boxes//trusty/0/virtualbox/Vagrantfile

并注意其他Vagrantfiles包含,即:

include_vagrantfile = File.expand_path("../include/_Vagrantfile", __FILE__)

现在它的工作原理:

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'trusty'...
==> default: Matching MAC address for NAT networking...
==> default: Setting the name of the VM: vagrant_default_1401234565101_12345

希望这可以帮助.

如消息所示,端口与主机盒发生冲突.我只是将端口更改为主机上的其他值.所以,如果我收到错误

config.vm.forward_port 80, 1234

然后我会把它改成

config.vm.forward_port 80, 5656

因为1234可能在我的主机上使用.

为了实际检查任何机器上的端口,我将该tcpview实用程序用于该操作系统,并了解在哪里使用哪个端口.

我遇到了这个问题,事实证明RubyMine仍然坚持一个端口.我通过运行此命令找出了哪个应用程序正在保留端口(在我的情况下为31337):

lsof -i | grep LISTEN

还要注意的是(在流浪1.6.4至少)有文件夹~/.vagrant.d/data/fp-leases,具有类似名称的文件8080,8081等这个删除文件夹的内容帮我刚才.
