1.设置git用户和邮箱

git config --global user.name "fujinzhou"

git config --global user.email "1445675350@qq.com"

2.生成SSH密钥

ssh-keygen -t rsa //直接敲3次回车，默认key放在/root/.ssh/下

3.在github上添加ssh密钥

cat /root/.ssh/id_rsa.pub //复制到github上（Settings-->SSH andGPG keys-->New SSH key）,title随意

4.测试认证是否成功

[root@localhost data]# ssh -T git@github.com

The authenticity of host 'github.com (192.30.253.113)' 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)? yes

Warning: Permanently added 'github.com,192.30.253.113' (RSA) to the list of known hosts.

Hi fujinzhou! You've successfully authenticated, but GitHub does not provide shell access.
