通过Ansible SSH进入无业游民的机器 [英] SSH into a Vagrant machine with Ansible

问题描述

通常，您可以使用vagrant ssh ssh进入由Vagrant管理的VM.有两种选择:

Normally, you can ssh into a Vagrant-managed VM with vagrant ssh. There are two options:

1. 您可以使用由Vagrant生成的insecure_private_key来 认证.
2. 使用您自己的私钥-前提是 config.ssh.forward_agent设置为true，并且VM为 配置正确

1. You can use an insecure_private_key generated by Vagrant to authenticate.
2. Use your own private key - provided that config.ssh.forward_agent is set to true, and the VM is configured correctly

我使用第二个选项. S当我运行vagrant ssh时，我使用自己的自定义私钥将其SSH进入计算机.

I use the second option. S when I run vagrant ssh, I ssh into the machine with my custom private key.

现在，我需要让Ansible SSH进入我的Vagrant计算机，并且我不想为此使用Vagrantfile.

Now I need to let Ansible SSH into my Vagrant machine and I do not want to use Vagrantfile for it.

所以我执行了:

ansible-playbook -i hosts/development --private-key=~/.ssh/id_rsa -u vagrant dev.yml

我返回了此错误:

致命:[192.168.50.5] => SSH错误:权限被拒绝(公钥). 而连接到192.168.50.5:22

fatal: [192.168.50.5] => SSH Error: Permission denied (publickey). while connecting to 192.168.50.5:22

hosts/inventory文件仅保存我的Vagrant VM的IP(192.168.50.5).

The hosts/inventory file holds just the IP of my Vagrant VM (192.168.50.5).

我不知道为什么Ansible无法ssh进入VM.它使用与执行vagrant ssh时完全相同的用户(vagrant)和键(id_rsa).

I do not know why Ansible cannot ssh into the VM. It's using exactly the same user (vagrant) and key (id_rsa) as when executing vagrant ssh.

但是，使用vagrant ssh进行sshing不会出现问题，而上述操作将无法运行.

However, there is no problem sshing with vagrant ssh while the above would not run.

任何建议将不胜感激.

推荐答案

问题可能出在您的hosts/inventory文件中.您需要在其中添加Ansible的正确连接配置，然后保存并重新运行.

The problem probably lies within your hosts/inventory file. You need to add the proper connection configuration for Ansible therein, save and re-run.

192.168.50.5 ansible_ssh_port=22 ansible_ssh_user=vagrant ansible_ssh_private_key_file=~/.ssh/id_rsa 

如果不使用端口22，请在主机文件中相应调整ansible_ssh_port.

If you are not using port 22, adjust the ansible_ssh_port in your hosts file accordingly.

您还可能没有在Vagrant中设置您的公钥，因此这也将不起作用.要对此进行测试，请运行:

It is also a possibility that you have not setup your pubkey in Vagrant, hence this would also not work. To test this, run:

vagrant ssh-config | grep IdentityFile
# result should be your private key and not
#   .vagrant/machines/default/virtualbox/private_key

如果您还没有将pubkey放入Vagrant虚拟机中，则需要先添加它，然后才能尝试使用私钥.

If you have not put your pubkey in the Vagrant vm, you will need to add that before you can try your private key.
