无法在我的AWS EC2实例中SSH

Question

在下方是正在吐出的错误。 我希望可以添加更多内容，但是我不确定围绕公钥的问题到底是什么。 我要添加更多单词，因为没有更多非代码字符就无法提交我的编辑。

命令->

Answer 1

似乎您没有提供要连接的用户名 。 如果它是标准的Amazon Linux实例，则使用ec2-user作为用户名：

ssh -v -i ta-tester-8.pem ec2-user@ec2-18-191-187-131.us-east-2.compute.amazonaws.com

没有该名称，它一直试图使用与系统上相同的用户名（ xxxx ）登录。
