Git SSH Key 生成步骤

1.查看是否已经有了ssh密钥：cd ~/.ssh
　　如果没有密钥则不会有此文件夹，有则备份删除
2.生存密钥：
　　$ ssh-keygen -t rsa -C "邮箱"
　　按3个回车，密码为空。

　　Your identification has been saved in /home/tekkub/.ssh/id_rsa.
　　Your public key has been saved in /home/tekkub/.ssh/id_rsa.pub.
　　The key fingerprint is:
　　………………

　　最后得到了两个文件：id_rsa和id_rsa.pub

　　id_rsa是RSA PRIVATE KEY，id_rsa.pub是公钥
