github ssh連接

Git是分佈式的代碼管理工具，遠程的代碼管理是基於SSH的，所以要使用遠程的Git則需要SSH的配置。
github的SSH配置如下：
1 、設置Git的user name和email：
$ git config --global user.name "xxxxx"
$ git config --global user.email "[email protected]"

2、生成SSH密鑰過程：
1）查看是否已經有了ssh密鑰：cd ~/.ssh
如果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 “[email protected]”
按3個回車，密碼爲空。

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

最後得到了兩個文件：id_rsa和id_rsa.pub

3）添加密鑰到ssh：ssh-add 文件名
需要之前輸入密碼。

4）在github上添加ssh密鑰，這要添加的是“id_rsa.pub”裏面的公鑰。
打開https://github.com/ ，登陸username，然後添加ssh。

5）測試：ssh -T [email protected]
The authenticity of host ‘github.com (207.97.227.239)’ 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)? yes
