服务器上Git存储文件的位置？

我根据这里的说明设置了git .但是,在创建测试文件,提交它并将其推送到服务器之后,我在git目录下的任何地方都看不到该文件.我希望它会出现在机器上的Web服务器可以看到它的某个地方,这样推送会立即显示出对服务器的http请求.

我知道git应该是更自包含的,在客户端,文件形成一个可以这种方式使用的很好的包.服务器不做同样的事情吗？

更新:我最初没有使用"裸"选项.但是当我这样做,并且我尝试从远程执行初始提交时,我收到了一条我不太了解的重大错误消息.

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'.

由于我从未检查过任何东西,我不知道这是什么意思,或者我应该做什么.
