查看git版本

git --version

如果没有git安装一下

配置git全局用户名和email

设置用户名和email

git config --global user.name "用户名"

git config --global user.email "邮箱@qq.com"

生成ssh key

ssh-keygen -t rsa -C "邮箱@qq.com"

三次回车，会提示公钥文件id_rsa.pub的存储路径

[root@ahuang bin]# ssh-keygen -t rsa -C 'test@qq.com'
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.

查看公钥并配置

[root@ahuang bin]# cat /root/.ssh/id_rsa.pub 

将输出信息完整的拷贝并配置到git的ssh key管理信息中
阿里云code的配置界面在项目界面-设置-ssh公钥中，找了半天md
然后就可以用ssh方式clone 项目了
