克隆git repo会导致错误 - 主机密钥验证失败.致命:远程端意外挂断

Question

我使用SSH将git repo克隆到我的Web服务器,但每次出现此错误

$git clone git@github.com:aleccunningham/marjoram.git
Cloning into marjoram...
Host key verification failed.

我已经尝试了几乎所有在谷歌搜索中出现的内容,而且我对为什么这不起作用感到茫然.有任何想法吗？

另外,我没有使用詹金斯这样的东西.

Answer 1

问题可能是你的〜/ .ssh/known_hosts文件中没有Github.

将GitHub附加到授权主机列表:

ssh-keyscan -H github.com >> ~/.ssh/known_hosts

Answer 2

解决了问题...您需要将ssh公钥添加到您的github帐户.

1. 验证是否已正确设置ssh密钥.
   1. 跑 ssh-keygen
   2. 输入密码(保留默认路径 - ~/.ssh/id_rsa)
2. 将公钥(~/.ssh/id_rsa.pub)添加到github帐户
3. 试试git clone.有用!

初始状态(公钥未添加到git hub帐户)

foo@bn18-251:~$ rm -rf test
foo@bn18-251:~$ ls
foo@bn18-251:~$ git clone git@github.com:devendra-d-chavan/test.git
Cloning into 'test'...
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
foo@bn18-251:~$

现在,将公钥添加~/.ssh/id_rsa.pub到github帐户(我用过cat ~/.ssh/id_rsa.pub)

foo@bn18-251:~$ ssh-keygen
