Mac下GitHub的SSH keys 生成配置

进入Mac终端，输入命令

1	$ cd ~/.ssh #检查本机的ssh密钥

如果提示No such file or directory 说明你是第一次使用

接下来生成新的SSH key：

$ ssh-keygen -t rsa -C "你的邮箱地址"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/your_user_directory/.ssh/id_rsa):<回车>
Enter passphrase (empty for no passphrase):<输入加密串><如不想设置密码可直接回车表示为空>
Enter same passphrase again:<再次输入加密串><接着回车确认>
Your identification has been saved in /Users/你的名字/.ssh/id_rsa).
Your public key has been saved in /Users/你的名字/.ssh/id_rsa.pub.
The key fingerprint is:
xx:xx:xx:xx:b1:f1:50:43:ad:20:a6:92:6a:1f:9a:3a "你的邮箱地址"

最后出现类似长方形的字符画即表示成功

此处可能会遇到的几个问题：

无法看到**.ssh**文件
解决方法：显示隐藏文件即可
如果你要设置密码，输入密码时是不会有***字样的，直接输入就可以了
##将SSH key添加到GitHub中

1	$ cd ~/.ssh #进入本机的ssh密钥目录

输入

$ ls

可以看到目录下有id_rsa.pub

输入

1	$ cat id_rsa.pub

接下来会出现一串以ssh-rsa开头的字符串例如：

ssh-rsa AXXXB3NzaC1yc2XXXiL+ytQ/r8cwouFVky9gyezQQw98Lw7Ji9BCljS28mGT7+/8BzxEjuxYXXXXXXXO5YQOTJkefjSZxusS71YwsQgEsLq3jx4uyDjc/DS3R5lWSydhDoXLdKQWEzd6Oe1COUzaH8+NA8TKQvYUm0gghXXXXXXY5J/M4tN4Pr73VKe5BzHytcvMkKk94Zst0Dvy707GJdOt30dJ7N XXX@XXXMacBook-Pro.local

将这段字符串复制，进入GitHub主业，点击右上角头像进入settings，选择SSH and GPG keys，再点击New SSH Key。将内容复制进key，title可以为空。最后Add SSH key，点击后会让你输入你的GitHub账户密码，正确输入后一般来说就成功了

通过如下命令进行测试是否成功

1	$ ssh -T git@GitHub.com #全部复制，无需更改

接下来会出现

The authenticity of host 'github.com (xx.x50.177.x23)' can't be established.
RSA key fingerprint is SHA256:nxxxxxxxxxxxxpRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes #这里填入yes
Warning: Permanently added 'github.com,13.250.177.223' (RSA) to the list of known hosts.
Hi XXXX! You've successfully authenticated, but GitHub does not provide shell access. #成功！

完成
