现在很多都是和git进行项目管理 但我们用HTTP 协议进行push的时候总是会遇到一些问题比如文件过大之类的。 决定用了SSH 协议。

设置Git的user name和email

$ git config --global user.name "humingx"
 $ git config --global user.email "humingx@yeah.net"

生成密钥

$ ssh-keygen -t rsa -C "humingx@yeah.net"

连续3个回车。如果不需要密码的话。
最后得到了两个文件：id_rsa和id_rsa.pub。

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/zhengmingxiang/.ssh/id_rsa): 
Created directory '/Users/zhengmingxiang/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/zhengmingxiang/.ssh/id_rsa.
Your public key has been saved in /Users/zhengmingxiang/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:GT1GWBv7F7VJ5PfPRSFkSwoAkxHQUVe5fPvnEdlDJgg 13365068888@sina.cn
The key's randomart image is:
+---[RSA 2048]----+

如果不是第一次overwrite选择y

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/zhengmingxiang/.ssh/id_rsa): 
/Users/zhengmingxiang/.ssh/id_rsa already exists.
Overwrite (y/n)? 

添加密钥到ssh-agent

$ ssh-add ~/.ssh/id_rsa

得到结果,这是后面要用到的文件的路径

Identity added: /Users/zhengmingxiang/.ssh/id_rsa (/Users/zhengmingxiang/.ssh/id_rsa)

登陆Github, 添加 ssh

前往路径把id_rsa.pub文件里的内容复制到这里管理密钥的key里面(相信大家可以自己找到添加的位置)。

测试

ssh -T git@github.com

你将会看到：

The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes

选择 yes

Hi godwar10! You've successfully authenticated, but GitHub does not provide shell access.

成功了。现在就可以使用ssh创建新仓库了

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin git@kd.gdgs.com:zhengmx_test.com/ww.git
git push -u origin master
