SSH 连接被拒绝，但公钥已注册

我正在尝试通过 ssh 连接到远程服务器。

  • 我正在使用我的id_rsa公钥，我已经用它连接到 GitHub 和 Bitbucket
  • 通过提供商的仪表板访问服务器，并将内容添加id_rsa.pub到~/.ssh/authorized_keys
  • 回到我的电脑前，尝试了一下ssh user@ip，得到了一个user@ip: Permission denied (publickey)

  • 因此，ssh user@ip -v返回以下内容（最后几行）：

    debug1: Next authentication method: publickey
debug1: Offering public key: RSA SHA256:blablablabla /home/username/.ssh/id_rsa
debug1: Authentications that can continue: publickey
debug1: Trying private key: /home/username/.ssh/id_dsa
debug1: Trying private key: /home/username/.ssh/id_ecdsa
debug1: Trying private key: /home/username/.ssh/id_ed25519
debug1: No more authentication methods to try.
user@ip: Permission denied (publickey).

另外：本地id_rsa.pub权限为 600，服务器权限.ssh/为 700，服务器权限authorized_keys为 744

我这里遗漏了什么吗？

在我看来，这就像尝试了你的密钥，但随后被拒绝：

user@ip: Permission denied (publickey).

重新添加您的密钥，看看是否正确。如果不是，请添加更多 -v（根据手册页）：

-v      Verbose mode.  Causes ssh to print debugging messages about its progress.  This is helpful in debugging connection, authentication,
        and configuration problems.  Multiple -v options increase the verbosity.  The maximum is 3.
