git操作

1、ssh生成

MacBook-Pro:~ hmh$ cd ~/.ssh

切换到ssh目录

MacBook-Pro:.ssh hmh$ ls
查看已存在的秘钥

MacBook-Pro:.ssh hmh$ git config --global user.name "hmh"

设置用户名

MacBook-Pro:.ssh hmh$ git config --global user.email "[e-mail]"

设置邮箱

MacBook-Pro:.ssh hmh$ ssh-keygen -t rsa -C "[e-mail]"

生成秘钥对

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/hmh/.ssh/id_rsa): //输入秘钥名称默认会得到id_rsa.pub，输入名称会得到用户名.ssh.pub           
/Users/hmh/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):  //输入密码 默认空
Enter same passphrase again:   //确认密码
Your identification has been saved in /Users/hmh/.ssh/id_rsa.
Your public key has been saved in /Users/hmh/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:k7D7HQGSmaB9b7Blt4LuBPZvX5raWLCUfNbSJRlbhF8 [e-mail]
The key's randomart image is:
