Git如何管理远程仓库分支？

It’s important to note that when you do a fetch that brings down new remote-tracking branches, you don’t automatically have local, editable copies of them. In other words, in this case, you don’t have a new serverfix branch — you have only an origin/serverfix pointer that you can’t modify

1. 推送本地分支到远程（远程没有该分支）

   git push <remote> <branch>

   例如将本地serverfix分支推送到远程，这样远程仓库也有serverfix分支了: git push origin serverfix

2. 本地拉取远程分支（本地没有该分支）：两步走-先拉取再checkout

   $ git fetch origin
   
   $ git checkout -b serverfix origin/serverfix
   

   拉取远程serverfix分支到本地的serverfix分支

3. 将本地已有分支与远程已有分支建立track关系

   如下在本地serverfix分支敲这个命令：将当前分支 与 远程仓库的serverfix分支建立track关系

   $ git branch --set-up
