１.问题描述：

在本地服务器搭建了git 之后，在客户端主机使用git push 出现如下错误：

jyq@jyq:~/work/Git/Robot$ git push origin master 
对象计数中: 5, 完成.
Delta compression using up to 4 threads.
压缩对象中: 100% (5/5), 完成.
写入对象中: 100% (5/5), 669 bytes | 0 bytes/s, 完成.

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: 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@192.168.30.11:/home/git/Code/Robot
 ! [remote rejected] master -> master (branch is currently checked out)
error: 无法推送一些引用到 'git@192.168.30.11:/home/git/Code/Robot'

2.解决办法：

这是由于git默认拒绝了push操作，在远程服务器主机执行如下命令：

git config receive.denyCurrentBranch ignore 

或者在.git/config中添加如下代码：

[receive]
    denyCurrentBranch = ignore
