Amazon web services AWS EC2 Instance无法连接ssh

我的公司里有人搞得一团糟，在这个实例上使用了一些权限。 我想我设法恢复了它们，但是的，我无法通过SSH连接。 我看到了所有的文档更改，因为他们建议我的.ssh文件夹和与之联系的文件的权限。 但仍然没有成功

以下是调试中看到的内容：

debug1: Host '[ec2-35-158-36-123.eu-central-1.compute.amazonaws.com]:922' is known and matches the RSA host key.
debug1: Found key in /home/mobaxterm/.ssh/known_hosts:33

debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

我只使用密钥验证。 我想可能是锁着的或不可写的，所以它无法拿到钥匙

Cab有什么帮助吗？

您是否尝试将公钥放置在授权密钥文件中，并为您的用户授予其完全权限

/home/username/.ssh/authorized_keys

您可以共享~/.ssh上的权限吗？您的用户id应该拥有主文件夹中的文件夹.ssh，该文件夹中的所有文件（包括该文件夹）都应有600个权限。我假设授权密钥已经存在，并且有人使用了您提到的权限
