Github fork 仓库与原仓库同步

• 进入 fork 项目目录，查看你的远程仓库路径

git remote -v

origin  https://github.com/YOUR_UERNAME/YOUR_FORK.git (fetch)
origin  https://github.com/YOUR_UERNAME/YOUR_FORK.git (push)

• 配置原仓库路径

git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git

• 再次查看远程目录位置

git remote -v

origin  https://github.com/YOUR_UERNAME/YOUR_FORK.git (fetch)
origin  https://github.com/YOUR_UERNAME/YOUR_FORK.git (push)
upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (fetch)
upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (push)

• 抓取原仓库的修改文件

git fetch upstream

• 切换到 master 分支

git checkout master

• 合并远程的 master 分支

git merge upstream/master
