提交代码：
git init
git remote add origin 远程仓库地址
git pull --rebase origin master
git add -A
git commit -m "备注"
git push -u origin master
Git 全局设置:
git config --global user.name "xxxxt"
git config --global user.email "xxxx@qq.com"
创建 git 仓库:
mkdir core_22_privilege_system
cd core_22_privilege_system
git init
touch README.md
git add README.md
git commit -m "first commit"
git remote add origin 远程地址
git push -u origin master
已有仓库?
cd existing_git_repo
git remote add origin 远程地址
git push -u origin master
github项目提交失败 master -> master (non-fast-forward)
git add -A
git commit -m "备注"
先执行git pull
然后再执行 git push --force origin master 替换原先的git push -u origin master
