机器在学习1：进入ssh文件下
cd ~/ .ssh2：生成ssh key
ssh-keygen -t rsa -C "你的邮箱"3：提示输入目录，目录可以不填，有默认路径，直接回车
// '()'里面是默认路径
Enter file in which to save the key (/Users/user/.ssh/id_rsa):4：提示输入密码, 密码可以不填, 默认没有密码，直接回车
5：提示再次输入密码
Enter passphrase (empty for no passphrase):
Enter same passphrase again: 6：当出现以下图案, 则表示生成 成功
Your identification has been saved in /Users/user/.ssh/id_rsa.
Your public key has been saved in /Users/user/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:IQP0sSMslL9VG+HXO9oqlnFNTkeI1/m9fBiBoKIcdxk nanananamln@163.com
The key's randomart image is:
+---[RSA 2048]----+
| .oo . E..o + . |
| ... o +o+..+ = |
| ..+ O.*o.... o.|
| o.=.*.o o.o o|
| oo S =o..o.|
| . . .oo..o.|
| +. . .|
| + . |
| . .. |
+----[SHA256]-----+6：打开.pub文件复制生成的ssh key粘贴到Git上即可
// 路径是上面的默认路径
sudo vi ~/.ssh/id_rsa.pub 也可以直接用命令把key复制到剪贴板
pbcopy < ~/.ssh/id_rsa.pub
7：配置一下Git
git config --global user.email "你的邮箱" git config --global user.name "你的名字"
