Amazon web services ssh到amazon ubuntu实例

当我从amazon web控制台创建amazon ubuntu实例并尝试使用ssh从任何远程计算机登录到该实例时，我可以登录，但当我使用ansible aws.yml文件创建ec2实例并尝试执行相同操作时，我无法连接，并收到一个错误

权限被拒绝（publickey）

来自每个远程主机，但我运行ansible脚本的主机除外。我的ansible文件中有什么地方做错了吗

这是我的可移植的yml文件

用于登录：

对于使用ssh登录，我将执行以下步骤

1-下载私钥文件

2-chmod 600私钥

3-ssh-vvv-i~/.ssh/sshkeys.pemubuntu@ec.compute-1.amazonaws.com

我收到错误

权限被拒绝（公钥）

您应该使用为连接到AWS实例而创建的密钥

转到EC2仪表板并查找实例，然后在运行中的实例上单击连接，您需要通过ssh连接到该实例

大概是 ssh-i“XXX.pem”ubuntu@ec2-X-XXX-XX-XX.XX-XXX-2.compute.amazonaws.com

将XXX.pem从安全组保存到您的计算机。

不是您系统的ssh密钥源

在Instance处于运行模式后，如何下载密钥对。在创建实例之前，我下载了正确的密钥对，但仍然收到相同的错误。您应该能够从设置中获得它。您是否为此位提供了正确的实例名称：

ubuntu@ec.compute-1.amazonaws.com

？
