当没有 .ssh 时，如何在没有密码的情况下通过 ssh 连接到服务器

Question

我想设置从我的本地机器无密码登录到这个 Linux 服务器。当我尝试上传我的 public 密钥时，我发现服务器上没有 .ssh。所以我在服务器上用 ssh-keygen 创建了一个。但是在新生成的.ssh 目录中，没有authorized_keys 或known_hosts。所以我制作了一个新的 authorized_keys 并从本地机器粘贴了我的 public 密钥。但是它不起作用，ssh 仍然需要密码。谁能告诉我我做对了吗？

这是 ssh -vvv 的输出：

debug1: Authentications that can continue: publickey,gssapi-with-mic,password,keyboard-interactive
debug3: start over, passed a different list publickey,gssapi-with-mic,password,keyboard-interactive

只需创建它并将您的密钥复制到其中即可。如果您有密钥复制工具，则只需通过

创建文件

$ touch ~/.ssh/authorized_keys

在使用该工具之前。

使用 -vvv 进行连接可能会有所帮助。

在客户端和服务器上，检查 ~/.ssh 是否具有权限 700。

在服务器上，检查 /etc/ssh/sshd_config 是否有：

AuthorizedKeysFile  .ssh/authorized_keys
PubkeyAuthentication yes
RSAAuthentication yes
