在 Windows 10 VM 上为 git bash 设置 ssh 密钥

Question

操作系统：带有 Windows 10 虚拟机的 Ubuntu

目标：在 Windows 10 虚拟机上设置 git bash，并使用 ssh 密钥与私有 Bitbucket 一起使用。

概述： 将 SSH 密钥生成到非默认位置以使用 git bash 不起作用。一个尝试的解决方案是创建默认位置并将密钥移动到该位置进行测试。我不太了解默认位置是如何生成的，或者 git bash 如何搜索 sshkey 以与 bitbucket 进行比较。我怀疑网络驱动器/IT 可能会影响问题，但不知道要问的正确问题。步骤和细节如下。是的，ssh 密钥已添加到 bitbucket 帐户。

生成 ssh 密钥时，建议的位置是 /home/username/.ssh... 我不确定这个建议的路径来自哪里。我已经用 git bash/ssh 键设置了几台计算机，这个建议的路径各不相同。 如何设置此建议路径？和如何设置 ssh 密钥搜索路径？

ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/plane/.ssh/id_rsa): /c/Users/username/.ssh/id_rsa

~ pwd = c/Users/username

/确实存在，但home不存在

权限被拒绝

mkdir -p /home/username
mkdir: cannot create directory ‘/home’: Permission denied

Git 克隆：

$ git clone ssh://git@git.example.com/project.git
Cloning into 'project'...
Could not create directory '/home/username/.ssh'.
The authenticity of host 'example' can't be established.
RSA key fingerprint is SHA256.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Failed to add the host to the list of known hosts (/home/username/.ssh/known_hosts).

编辑：

我也尝试过以下方法。

为了指出 .ssh 的实际位置以及我想要的位置。 /c/Users/plane/.ssh

git config --global core.sshCommand "ssh -i ~/.ssh/id_rsa.pub"

1) 无法创建 '/home/plane/.ssh'

2) 未能将主机添加到已知主机列表(/home/plane/.ssh/known_hosts)。

3) 加载密钥“/c/Users/plane/.ssh/id_rsa.pub”：格式无效

git clone ssh://git@git.project
Cloning into 'project'...
Could not create directory '/home/plane/.ssh'.
The authenticity of host can't be established.
RSA key fingerprint is SHA256:.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Failed to add the host to the list of known hosts (/home/plane/.ssh/known_hosts).
Load key "/c/Users/plane/.ssh/id_rsa.pub": invalid format
Permission denied (publickey).
fatal: Could not read from remote repository.

and the repository exists.

谢谢，

你应该使用：

• 具有简化路径的常规 CMD（在您的 Windows 10 虚拟机中）

  set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
  set GH=C:\path\to\git
  set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%
  

• 在默认 %USERPROFILE%.ssh 文件夹中生成的密钥

  ssh-keygen -P "" -t rsa -m PEM
  

• 将id_rsa.pub内容注册到your BitBucket profile

---

known_hosts 仍被默认位置 /home/username/.ssh 引用。
如何更改此默认位置？

这是由$HOME/%HOME% 环境变量管理的。
SSH 将在$HOME/.ssh 中寻找known_hosts
