Question

我正在使用Vagrant运行4个VM。我的Vagrantfile看起来像这样：

Vagrant.configure(2) do |config|
  config.vm.box = "bento/centos-7.2"
  config.vm.synced_folder "data", "/vagrant"

  # Master1
  config.vm.define :master1 do |m1|
    m1.vm.hostname = "master1.mycluster"
    m1.vm.network :private_network, ip: "192.168.0.12"
    m1.vm.provider :virtualbox do |vb|
      vb.memory = "8192"
    end
    m1.vm.network "forwarded_port", guest: 50070, host: 50070
  end

  # Other machines are defined in the same way
end

一切都运行良好，直到我不小心从项目目录中删除了.vagrant文件夹。

首先，我尝试将我的VM ID放回.vagrant/machines/${name}/virtualbox/id。运行vagrant status确实看到我的虚拟机已启动并正在运行，但我无法通过SSH连接。

我找了一个解决方案，但找不到一个，所以我决定销毁并重新启动我的虚拟机。遗憾的是，vagrant up（或vagrant up --provision）命令试图通过SSH连接到 127.0.0.1:2222 。不应该尝试连接到 192.168.0.12:2222 吗？这是命令输出：

但是，我可以通过ssh -p 2222 vagrant@127.0.0.1连接到我的VM，而SSH文件夹似乎没有权限问题。

[vagrant@localhost ~]$ ls -la /home/vagrant/.ssh/

如何使用Vagrant再次运行VM？

TL; DR：请勿修改~/.vagrant.d/insecure_private_key

在尝试修复第一个问题时（在.vagrant中放回VM ID后无法连接到VM），我在某个地方发现了一个帖子，告诉我这是一个文件流浪者不安全私钥的问题，位于{ {1}}。

我试图在那里放置一个自定义私钥，这就是为什么以后使用vagrant up不起作用的原因。

解决方案是在此处找到默认的Vagrant不安全私钥：https://github.com/mitchellh/vagrant/tree/master/keys，并将其放回~/.vagrant.d/insecure_private_key。

已删除的.vagrant目录阻止我使用SSH
