在window下安装github客户端上传代码
第一步：创建Github新账户
第二步：新建仓库
第三步：安装Github shell程序，地址：http://windows.github.com/
第四步：打开Git Shell，输入以下命令生成密钥来验证身份
$ ssh-keygen -C 'your@email.address' -t rsa
连续三个回车之后会在windows当前用户目录下生成.ssh文件夹，和linux一样。
第五步：在Git Shell下输入命令测试刚才的公钥是否认证正确。
$ ssh -T git@github.com
第六步：clone刚才新建的repository 到本地，输入命令：
git clone https://github.com/XXXXX/XXXXXX.git
第七步：将想上传的代码目录拷贝到此文件夹下：
第八步：切换到Git shell 命令行下，输入命令：
git init
git add .
git commit -m 'xxxxxx'
git remote add origin https://github.com/xxxxx/xxxxx.git
git push origin master
(1)如果执行git remote add origin https://github.com/xxxxx/xxxxx.git，出现错误：
fatal:remote origin already exists
则执行以下语句：
git remote rm origin
再往后执行git remote add origin https://github.com/xxxxx/xxxxx.git即可。
(2)在执行git push origin master时，报错：
$ git push origin master
To https://github.com/qq20707/DesignPatterns.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/qq20707/DesignPatterns.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
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.
error:failed to push som refs to .....
则执行以下语句：git pull --rebase origin master
(3)如果出现错误 “refusing to merge unrelated histories”
git pull origin master --allow-unrelated-histories
先把远程服务器github上面的文件拉先来，再push 上去。
