1, the installation
1、1 使用yum安装的
命令：$ yum install git git-gui
2 generates a key pair using ssh-keygen Method
ssh-keygen -t [rsa | dsa], will generate the key and the key file id_rsa, id_rsa.pub or id_dsa, id_dsa.pub
3, the generated public key is copied to github.com in SSHKEY
$mkdir .ssh
$cd .ssh/
$ssh -keygen -t rsa -C 'qq.com'
如果出现产生的ssh-key无效的错误，请改为一行行的复制公钥内容，注意不要将空格，换行符等复制进来。
特别注意第一个字符不要漏了。
4, log on github. Open setting-> SSH keys, top right corner New SSH key, to generate a good id_rsa.pub public key into the input box, then a title from the current key to distinguish each key.
5, test
将key添加之后，我们测试下能否链接到github。
命令：$ ssh [email protected]

Common Errors
1, ssh connection to the server error
