问题记录
在git clone github仓库代码时，出现以下bug：
$ git clone [email protected]:ximury/vue.git
Cloning into 'vue'...
The authenticity of host '[ssh.github.com]:443 ([18.138.202.180]:443)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '[ssh.github.com]:443,[18.138.202.180]:443' (RSA) to the list of known hosts.

fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
再次尝试后，就是这种情况：
$ git clone [email protected]:ximury/vue.git
Cloning into 'vue'...
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
原因分析
在.ssh目录下生成一个github的SSH-Key时，自定义了文件名，如下：
$ ssh-keygen -t rsa -C '[email protected]' -f ~/.ssh/github_id_rsa
然后就将.pub文件复制粘贴到github网站上的SSH keys中。
之后直接进行clone代码，就出现了以上BUG。
问题解决
方式一
使用命令 ssh-keygen -t rsa 直接生成默认的rsa文件，之后在github上配置pub即可
方式二
生成rsa文件时自定义文件名，需要在 .ssh 目录下添加一个config文件，样例如下：
# gitee
Host gitee.com
HostName gitee.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/gitee_id_rsa
# github
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github_id_rsa
注意： 其中 Host 和 HostName 后填写 git 服务器的域名，IdentityFile 指定私钥的路径（只需要修改 IdentityFile ）
测试成功与否
ssh -T [email protected]
如果成功：
Hi ***! You've successfully authenticated, but GitHub does not provide shell access.
如果测试结果失败：
Warning: Permanently added the RSA host key for IP address '13.229.188.59' to the list of known hosts.

执行下面命令制定目标Git账号：
ssh-add -k id_rsa
id_rsa文件对应之前生成的rsa文件
之后再执行测试命令即可！
