尝试 SSH 时出现“权限被拒绝（公钥）”并显示“key_load_public：没有此文件或目录”

运行时我不断收到以下错误。ssh -v -i privatekey [email protected]

我不明白哪里出了问题。我已经正确复制了我的公钥，并编辑了私钥文件的权限以确保其安全。

答案1

“权限被拒绝”错误意味着服务器拒绝您的连接。

  1. 检查 SSH 上的日志。
  2. 你是如何将公钥传输到服务器的？始终确保ssh-copy-id权限。用户主目录、.ssh 目录和 authorized_keys 文件在服务器端有严格的权限要求。（参见man sshd有关authorized_keys）。
  3. 查看服务器配置文件/etc/ssh/sshd_config也许服务器只允许特定的用户或组登录。

答案2

考虑到 Slipeer 的回答，以下是详细添加到 /etc/ssh/sshd_config 的内容。

在我的例子中，我尝试克隆一个 gitlab 项目，该解决方案应该适用于任何 git 服务。错误是

#15 0.589 debug1: identity file /root/.ssh/id_rsa type -1, 
#15 0.589 debug1: key_load_public: No such file or directory

使用后消失

echo "Host *\n  User git\n  HostName gitlab.com\n  AddKeysToAgent yes\n  IdentityFile /root/.ssh/id_rsa" >> /etc/ssh/ssh_config

这也是您在消息块中所要求的内容：

debug1: Reading configuration data /etc/ssh/ssh_config
...
debug1: key_load_public: No such file or directory

解决方案证明 ssh 需要检查服务器是否为已知主机。如果你没有指定所需的已知主机，则 gitlab 服务器不受信任，这就是 的意思the key_load_public cannot be found。是的，错误消息令人困惑。

echo当然，您也可以不使用命令来手动填写 ssh_config 。
