一、具体过程：

二、遇到问题及理解错误的地方
１．ssh
已经使用过ssh连接其他的网站，如果按前述教程重新生成了id_rsa和id_rsa.pub，则有可能会报错： Agent admitted failure to sign using the key.
解决办法 ssh-add即可
２．创建repository
这个只能通过firefox或者chrome在github上创建，不能通过git创建
３．执行git push -u origin master报错：
To git@github.com:dengshiyong/nginx-module-developed-by-cpp ! [rejected] master -> master (fetch first) error: failed to push some refs to 'git@github.com:dengshiyong/nginx-module-developed-by-cpp' hint: Updates were rejected because the remote contains work that you do hint: not have locally. This is usually caused by another repository pushing hint: to the same ref. You may want to first integrate the remote changes hint: (e.g., 'git pull ...') before pushing again. hint: See the 'Note about fast-forwards' in 'git push --help' for details.
解决办法： git pull git@github.com:dengshiyong/nginx-module-developed-by-cpp 再 git push -u origin master
