git push到自己仓库时报错master -＞ master (branch is currently checked out)

背景

因为要在两个系统中共同更新一个博客，但是linux系统读取windows系统文件为只读模式。因此想到通过自己服务器上的git仓库来实现博客同步。

在服务器上init一个名为blog的仓库后，在本地进行push却报错

remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository
remote: error: is denied, because it will make the index and work tree inconsistent
remote: error: with what you pushed, and will require 'git reset --hard' to match
remote: error: the work tree to HEAD.
remote: error: 
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you
remote: error: arranged to update its work tree to match what you pushed in some
remote: error: other way.
remote: error: 
remote: error: To squelch this message and still keep the default behaviour, set
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
To 81.70.200.226:/home/git/repos/blog
 ! [remote rejected] master -> master (branch is currently checked out)

问题分析

远程仓库包含worktree，即git认为远程仓库为另一个人的另一个项目，所以不允许提交push。

解决办法

在初始化远程仓库时，使用git --bare init而不是git init
