本文主要参考：http://www.07net01.com/2015/11/1000704.html 得以解决问题
一、使用git在本地创建一个项目的过程
首先得在github或者git@OSC上创建一个hello-world项目。本地才能进行推送
$ makdir ~/hello-world //创建一个项目hello-world
$ cd ~/hello-world //打开这个项目
$ git init //初始化
$ touch README
$ git add README //更新README文件
$ git commit -m 'first commit' //提交更新，并注释信息“first commit”
$ git remote add origin [email protected]:defnngj/hello-world.git //连接远程github项目 当然 origin还可以 origin_new
$ git push -u origin master //将本地项目更新到github项目上去
执行：git push -u origin master -f 以及 git push origin master
二、其他常用命令：
git remote -v //查看地址
git config --list //查看配置
git status //查看状态
git remote rm origin //删除origin这个push地址
rm -rf ~/.ssh 删除.ssh 文件和文件夹
rm -f ~/.ssh 删除文件
三、git push遇到的问题：
本来想用 ssh传输的，结果用ssh传输总是报错：
Administrator@PC201611290918 MINGW64 /d/Git@OSC/SpringMVC (master)
$ git remote add origin [email protected]:MaGary/SpringMVC.git
Administrator@PC201611290918 MINGW64 /d/Git@OSC/SpringMVC (master)
$ git push -u origin master
Access denied.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Administrator@PC201611290918 MINGW64 /d/Git@OSC/SpringMVC (master)
$ git pull
Access denied.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
先在gitHUb或则Git@OSC上创建项目。后来我改用 https地址提交项目：
https://git.oschina.net/MaGary/SpringMVC.git/
重新设置remote地址： git remote add origin https://git.oschina.net/MaGary/SpringMVC.git
接着进行 push操作：结果报错：（git push -u origin master 以及 git push origin master）度有错：都是：![rejected] master -> master(fetch first); ![rejected] master -> master(non-fast-forward);
Administrator@PC201611290918 MINGW64 /d/Git@OSC/SpringMVC (master)
$ git push -u origin master

! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://git.oschina.net/MaGary/SpringMVC.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
