1、生成秘钥
//换成你自己的邮箱
ssh-keygen -t rsa -C "*********@example.com"
//一直next并记住生成的地址
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
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.
2、提取 key
[root@localhost ~]# cd .ssh
[root@localhost .ssh]# ls
id_rsa  id_rsa.pub
//把显示的内容复制到GitHub的SSHkey配置即可
[root@localhost .ssh]# cat id_rsa.pub
3、测试是否连通
[root@localhost .ssh]# ssh -T git@github.com
The authenticity of host 'github.com (192.30.255.113)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes
Warning: Permanently added 'github.com,192.30.255.113' (RSA) to the list of known hosts.
Hi megoc! You've successfully authenticated, but GitHub does not provide shell access.
4、查看连接方式
git remote -v 
--origin	https://github.com/*/*.git (fetch)
--origin	https://github.com/*/*.git (push)
上面方法虽然能够连通github,但是每次push的时候都需要输入用户名和密码
通过1、2、3已经生成了ssh  改换成ssh连接方式就不需要每次都输入密码
git remote rm origin 
git remote add origin git@github.com:用户名/库名.git
git remote -v
--origin	git@github.com:用户名/库名.git (fetch)
--origin	git@github.com:用户名/库名.git (push)
再次push 发现不需要输入密码也能够成功。
