我正在安装杰斯普特并且在尝试运行时ssh -p 4022 jhipster@localhost，系统要求输入密码。
bash-3.2$ cat ~/.ssh/id_rsa.pub | ssh -p 4022 jhipster@localhost 'mkdir ~/.ssh && cat >> ~/.ssh/authorized_keys'
jhipster@localhost's password:
我应该如何配置/跳过此密码。我已经看过一些帖子，但它们似乎都在讨论 Linux。

答案1
无密码 ssh 是一个鸡和蛋的问题。直到你设法成功地在中输入~/.ssh/id_rsa.pub内容，以 身份进行 ssh 时系统会提示您输入密码。您需要输入密码才能使 cmd 成功（假设它是正确的）。jhipster~/.ssh/authorized_keysjhipster
对于 cmd 来说同样如此ssh-copy-id。
由于您已经遇到困难，我建议您尽量让事情变得简单。
- 第一个目标是变得
jhipster@localhost（否则您无法更新authorized_keys文件）
一种方法是使用 ssh（您需要输入密码）：
ssh -p 4022 jhipster@localhost
如果你没有/无法输入密码（比如不知道密码或没有设置密码），但你有根/sudo您可以尝试以下访问：
sudo su - jhipster
或者分别以 root 身份：
su - jhipster
- 登录后，
jhipster您可以像这样更新您的文件：
mkdir -p ~/.ssh touch ~/.ssh/authorized_keys cat ~abhishek/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
jhipster注意：最后的命令考虑到了其他用户 ID 已经在中拥有其密钥的可能性，~/.ssh/authorized_keys这些密钥可能需要保留。
