Git Error: failed to push some refs to Updates were rejected because the remote contains work tha

1、运行git push -u origin master 时报错如下：
! [rejected] master -> master (fetch first)
error: failed to push some refs to ‘[email protected]:******/configserver.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.

修改方案：
先 运行git pull --rebase origin master，【注：pull=fetch+merge]
将远程仓库代码拉到本地合并后；
再运行git push -u origin master即可完成代码上传到github

2、将本地仓库上传到远程仓库步骤
1）git init #创建本地仓库
2）git add . #添加所有文件
git add somefile #添加某一个文件
3）git commit -m ‘第一次提交’ #将文件添加到仓库
4）git remote add origin [email protected]*****/configserver.git #连接仓库
5）git push origin master #将本地代码提交到远程仓库
如果报上面的错误的话，先执行git pull --rebase origin master，
再执行 git push origin master
其他：git status #查看状态
