Question

即使我已经把我的public_key放在那里，我也无法访问我的远程服务器。这是日志，当我做了一个＆＃34; ssh -v ubuntu@website.com"：

ssh -v ubuntu@plumbersserver.net

请帮忙。我不知道自己做错了什么。

Answer 1

尝试以下问题排查步骤：

确保您的公钥已保存在正确的目录中：
/home/ec2-user/.ssh
确保您的公钥具有分配给它的正确权限： 0600
chmod 0600 /home/ec2-user/.ssh/your_public_key
使用ssh的-i标志进行连接时，请确保使用正确的私钥。 ssh -i ~/.ssh/your_private_key.pem ec2-user@website.com
确保您的私钥也具有 0600

如果您无法连接到该实例，以验证步骤1＆amp;在上面的图2中，然后停止实例，分离根卷，并将其附加并挂载到可用实例。

Answer 2

由于您以'ubuntu'用户身份登录，因此在ec2实例中，您的公钥应附加到文件：/home/ubuntu/.ssh/authorized_keys。如果该文件不存在，请使用您的公钥内容创建该文件，并确保将文件权限设置为600.

权限被拒绝（publickey）。连接到AWS服务器时
