Git SSH Key 生成步驟

1.查看是否已經有了ssh密鑰：cd ~/.ssh
　　若是沒有密鑰則不會有此文件夾，有則備份刪除
2.生存密鑰：
　　$ ssh-keygen -t rsa -C "郵箱"
　　按3個回車，密碼爲空。

　　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:
　　………………

　　最後獲得了兩個文件：id_rsa和id_rsa.pub

　　id_rsa是RSA PRIVATE KEY，id_rsa.pub是公鑰
