我可以ssh到OpenStack实例，但Ansible可以'；它有什么不同之处？,ssh,ansible,openstack,Ssh,Ansible,Openstack,我在OpenStack中创建了一个Ubuntu实例，并检索了pem文件，以允许我从我的控制机器ssh到它。我总共只有两台机器：我的控制机器运行Ubuntu并安装了Ansible 2.0.0.2，我的Openstack实例也运行Ubuntu 通过该控制机器，我可以使用以下ssh： ssh -i /home/lovea/.ssh/ggcloud-keypair.pem ubuntu@192.168.138.107 这是可行的-没有任何额外的击键，我就登录到OpenStack实例 但是我想使用Ans

我在OpenStack中创建了一个Ubuntu实例，并检索了pem文件，以允许我从我的控制机器ssh到它。我总共只有两台机器：我的控制机器运行Ubuntu并安装了Ansible 2.0.0.2，我的Openstack实例也运行Ubuntu

通过该控制机器，我可以使用以下ssh：

ssh -i /home/lovea/.ssh/ggcloud-keypair.pem ubuntu@192.168.138.107
这是可行的-没有任何额外的击键，我就登录到OpenStack实例

但是我想使用Ansible——运行在同一台控制机器上——来配置Ubuntu实例。在
/etc/ansible/ansible.cfg
中，我将私钥文件设置为使用与ssh相同的文件。然后，我尝试使用以下Ansible命令ping Openstack实例：

ansible -vv --become-user ubuntu -i '192.168.138.107,' all -m ping
据我所知，Ansible应该尝试使用相同的ssh凭据以用户身份连接ubuntu。然而，我得到的答复是：

192.168.138.107 | UNREACHABLE! => {
    "changed": false,
    "msg": "ERROR! SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue",
    "unreachable": true
}
按照指示，我使用
-vvvv
重新运行此命令，但有很多输出：
