vagrant + Permission denied 造币厂

Question

我只用了 2 天。我看到很多类似的帖子，但我无法解决我的问题。

我将 Mint 18 作为主要操作系统 (4.4.0-21-generic#37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux)，现在我有:

• virtualbox 5.0.40 r115130

• Vagrant 1.8.4 + vagrant-vbguest (0.14.2)

虚拟机安装正确。当我尝试运行“vagrant ssh”时，我看到:

Permission denied (publickey)

我的配置:

Vagrant.configure(2) do |config|
  config.vm.box = "debian/jessie64"
  config.vm.network "forwarded_port", guest: 80, host: 8080, auto_correct: true
  config.vm.network "private_network", ip: "192.168.56.106"
  config.vm.synced_folder '.', '/home/vagrant'  
end

Synced_folder 工作正常。

Vagrant ssh 配置

 Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /home/wiktor/NetBeansProjects/PhpProject1/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

并且:ssh -i/home/wiktor/NetBeansProjects/PhpProject1/.vagrant/machines/default/virtualbox/private_key -v vagrant@localhost -p 2222

我不明白这个错误。可能 vagrant 无法生成公钥。

通过 VirtualBox 连接到 VM 并运行“ls -la/home/vagrant”后，我没有看到目录“.ssh”。对吗？

我尝试运行 virtualbox 5.1 和 vagrant 1.8.5，但我有同样的错误。

当我在不正确的公钥/私钥后使用 Windows10 时，这会向 vagrant 用户请求密码。On Mint 返回错误。我在客户机和主操作系统上更改了 chmod 并编辑了/etc/ssh/sshd_config。这没有帮助。

有人能帮忙吗？

问题是由于您的 vagrantfile 中的以下行

  config.vm.synced_folder '.', '/home/vagrant' 

vagrant 用户的 authorized_keys 文件位于 vagrant 机器内的 /home/vagrant/.ssh 中，可以通过 ssh 进入 vagrant box。

当您将当前目录挂载到 /home/vagrant 时，/home/vagrant 的所有内容都被覆盖并且没有 authorized_keys 文件。

将安装路径更改为除 /home/vagrant 之外的任何内容，您将能够通过 ssh 进入机器。例如

  config.vm.synced_folder '.', '/home/vagrant/somepath'
