有时候我们使用git push向远程仓库推送的时候，会报错如下：
[remote rejected] master -> master (branch is currently checked out) 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 git@192.168.1.X:/var/git.server/.../web ! [remote rejected] master -> master (branch is currently checked out) error: failed to push some refs to 'git@192.168.1.X:/var/git.server/.../web'
这是因为git默认是拒绝push操作的，我们在.git/config里面添加如下配置项即可：
[receive] denyCurrentBranch = ignore
这是当我们初始化一个远程仓库的时候，使用git --bare init即可了，而不是使用git init，这样那么该远程仓库的目录下，也包含work tree，当本地仓库向远程仓库push时，如果远程仓库正在push的分支上时，那么push后的结果不会反映在work tree上，也就是在远程仓库的目录下对应的文件还是之前的内容，必须使用git reset --hard才能看到push之后的内容。
注意如果当时不在push的分支上，是没问题的。
