GitHub 配置SSH

1.创建SSH Key

ssh-keygen -t rsa -C "你的邮箱账号" 

回车键后会有下面显示：

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/now/.ssh/id_rsa): '这里输入文件名字 比如id_rsa'

然后会提示让输入密码：这个密码是 push时候的密码 不是github的密码

Enter passphrase (empty for no passphrase):
Enter same passphrase again:

会有下面提示

Your identification has been saved in id_rsa.
Your public key has been saved in id_rsa.pub.
The key fingerprint is:
SHA256:6z7Ya7lLkRKld266nSb6oKcAkCm0Sv/zSmud2R/U2uM you-mail@mail.com
The key's randomart image is:
+---[RSA 2048]----+
| .      .        |
|.o.    o         |
|=o    o . .      |
|= .    o +  .    |
|o  .  . S o. .   |
| .  .  . =. o    |
|  .  +ooB. o o   |
|   ..o*B*+..o .  |
|    +=o*OB+. E   |
+----[SHA256]-----+

这就创建完成了，然后找到id_rsa.pub文件 可以拖到浏览器查看文件内容，复制。

2.把SSH Key添加到Github仓库中

打开Github ->设置 –> SHH和GPG秘钥 -> New SSH key
把获取到秘钥粘贴进去就ok了

3、验证是否可用

在终端输入：

ssh -T git@github.com

出现下面就可以用了

Hi 用户名! You've successfully authenticated, but GitHub does not provide shell access.
