Git设置SSH Key

一、git 配置

（1）打开 git 命令窗口

（2）配置用户名（填自己的姓名）
          git config --global user.name “xinyu.xia”

（3）配置用户邮箱（填自己的邮箱）
          git config --global user.email “[e-mail]”

（4）生成公钥、秘钥（填自己的邮箱，执行后需要按几次 enter 直到结束）
          ssh-keygen -t rsa -C “[e-mail]”

ssh-keygen -t rsa -C “[e-mail]” Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xinyu.xia/.ssh/id_rsa): 
Created directory '/Users/xinyu.xia/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/xinyu.xia/.ssh/id_rsa
Your public key has been saved in /Users/xinyu.xia/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:QsGezVQx8Ss3u3MtdFE6m6pFdFE3hDNpOq5NFN/CPo4 “[e-mail]”
The key's randomart image is:
+---[RSA 3072]----+
|     ..  .=o  =+o|
|      ...  + * .+|
|     ..=    O =..|
|     .o o  = *oo |
|      . S + B .+.|
|       .   * =+ .|
|          + =o.o |
|         . Eooo .|
|          ...o . |
+----[SHA256]-----+

（5）配置 ssh 变量
          git config --global ssh.variant ssh

二、gitlab 配置公钥

（1）打开生成公钥的文件夹

xinyu.xia@XinyuXiadebijibendiannao .ssh % cd /Users/xinyu.xia/.sshxinyu.xia@XinyuXiadebijibendiannao .ssh % ls  
id_rsa		id_rsa.pubxinyu.xia@XinyuXiadebijibendiannao .ssh % cat id_rsa.pub 
ssh-rsa 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 “[e-mail]”

（2）复制公钥文件内容，公钥文件名

 （3）下载代码

xinyu.xia@XinyuXiadebijibendiannao workspace % git clone [e-mail]:xxx/xx.git
