Question

我正试图通过我的电脑上的ssh连接到我的ec-2免费（t2.micro）实例。

我用默认的VPC创建了实例。我无法从我的电脑上连接它。

这是我拒绝许可的错误。

我已检查过安全组中的规则。

我已经通过以下网址检查答案，但没有成功。

AWS SSH connection error: Permission denied (publickey)

Troubleshooting Connecting to Your Instance

SSH: Permission denied (publickey)

当我在命令

下运行时

sudo ssh -v -i tep-keyPair.pem ubuntu@ec2-52-XX-XXX-XX.us-west-2.compute.amazonaws.com

出现以下错误：

请帮助我..我真的被困在这里

Answer 1

您收到Permission denied (publickey)错误的事实表明您已成功与实例通信，因此问题与网络或安全组无关。

相反，实例不接受通过您提供的密钥对的连接。因此，您需要为其提供预期的密钥对，或者您可以将新密钥对复制到实例。

要将不同的密钥对复制到实例，请按照针对Ubuntu编写的StackOverflow应答的说明进行操作：Change key pair for ec2 instance
