vagrant 自定义 ssh 密钥身份验证失败

Question

下面是我的 Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

#Virtualbox host and vagrant host/network confs
#
Vagrant.configure("2") do |config|
  config.vm.define "slave" do |slave|
    slave.vm.box = "centos/7"
    slave.vm.hostname = "slave.ansible.com"
    slave.vm.network :private_network, ip: "192.168.99.102"
    slave.ssh.insert_key = false
    slave.vm.boot_timeout = 800
    slave.ssh.private_key_path = ["keys/id_rsa_slave"]
    slave.vm.provision "file", source: "keys/id_rsa_slave.pub", destination: "~/.ssh/authorized_keys"
  end

    config.vm.provider "virtualbox" do |vb|
      vb.cpus = "1"
      vb.memory = "512"
    end

这个 Vagrantfile 位于我的主目录 (/user/gokul/slave) 下的 slave 文件夹中，在此之下，我有具有以下密钥和适当权限的密钥目录

(base) Gokul:slave gokul$ ls -lt keys/
total 16
-rw-------  1 gokul  gokul   565 May 16 18:30 id_rsa_slave.pub
-rw-------  1 gokul  gokul  2590 May 16 18:30 id_rsa_slave

keys目录权限也可以

(base) Gokul:slave gokul$ ls -ld keys/
drwx------  4 gokul  gokul  128 May 16 18:30 keys/

现在我运行下面的命令来启动我的 vagrant box

vagrant up

此时挂起，无法验证

==> master: Waiting for machine to boot. This may take a few minutes...
    master: SSH address: 127.0.0.1:2200
    master: SSH username: vagrant
    master: SSH auth method: private key
    master: Warning: Authentication failure. Retrying...
    master: Warning: Authentication failure. Retrying...

SSH authentication failed! This is typically caused by the public/private
keypair for the SSH user not being properly set on the guest VM. Please
verify that the guest VM is setup with the proper public key, and that
the private key path for Vagrant is setup properly as well.

启用调试后，我还可以看到它获取了我要求的私钥，但是，它无法成功验证并因上述错误而失败。

Answer 1

想通了。我使用的自定义键应该附加到默认的 vag运行t 键 - ~/.vag运行t.d/insecure_private_key

所以这个配置

slave.ssh.private_key_path = ["keys/id_rsa_slave"]

应该改为

slave.ssh.private_key_path = ["keys/id_rsa_slave", "~/.vagrant.d/insecure_private_key"]

进行此更改后，我运行

vagrant up

并且上线成功
