1.如果是本地刚刚搭建好git环境，第一次和gitlab服务器产生连接
参照这个文
https://www.cnblogs.com/kaerxifa/p/10929098.html
2.已经和gitlab产生连接（提交代码到过仓库A，现在要第一次提交代码到仓库B）
和上文大同小异
step1:
1.先在gitlab创建一个仓库，将项目clone至本地（为了得到.git文件，和远程的gitlab仓库产生连接）
root@wangju-HP-348-G4:/home/wangju/PycharmProjects# git clone http://git.xxxx.com/kaifa/reponselogiccheck.git
正克隆到 'reponselogiccheck'...
remote: Enumerating objects: 33, done.
remote: Counting objects: 100% (33/33), done.
remote: Compressing objects: 100% (22/22), done.
remote: Total 33 (delta 3), reused 31 (delta 3)
展开对象中: 100% (33/33), 完成. 2.将已经写好的项目目录（不要项目名，只要项目文件）复制到clone好的文件夹中
3.
git add . git commit -m "first commit" git push -u origin master well done 项目代码就提交到仓库了
Git global setup
git config --global user.name "集成账号"
