1 检查是否已经存在ssh key

通常sshkey会默认生成在用户家目录下，所以查看家目录下是否存在.ssh 文件夹，以及是否存在相关目录就行。（~/.ssh/id_rsa）

2 生成key

在git bash中输入

ssh-keygen -t rsa -C "你的邮箱地址"

控制台输出如下:

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Shusheng Shi/.ssh/id_rsa):
Created directory '/c/Users/Shusheng Shi/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Shusheng Shi/.ssh/id_rsa.
Your public key has been saved in /c/Users/Shusheng Shi/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:mCl+F1RXrr/R/XjNNpZx37esSU/01P3LKLkSPu7gRQM sss2855845850@gmail.com
The key's randomart image is:
+---[RSA 2048]----+
|          . ...  |
|         . . .   |
|       E.     .  |
|       =.    .  o|
|    . + So  .  .+|
|   . .  .o.  ..+=|
|    . ..o.. ..oo%|
|     ...o+ o. BB@|
|       .ooo.o+=O=|
+----[SHA256]-----+

为了避免每次进行ssh连接时都需要输入passphrase，这里可以不用输入passphrase,一直回车
现在你的私钥被放在了~/.ssh/id_rsa 这个文件里，而公钥被放在了 ~/.ssh/id_rsa.pub 这个文件里。

3 git clone

在本地项目目录的doc文件夹路径下执行

 git clone git@gitee.com:ssshappymmall/mmall-fe.git

输出:

Cloning into 'mmall-fe'...
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (3/3), done.

至此,git仓库建立完毕

git remote add orgin git@gitee.com:ssshappymmall/mmall-fe.git

将当前文件夹与远程项目地址映射联系
