sudo git --bare init

cd ..

sudo chmod -R 777 gitService

cd gitService

sudo vim config

插入：

[receive]denyCurrentBranch = ignore， 记得属性换行！不能有多余的空格，否则报错。

Shift + G, 再输入o， w保存，q退出，冒号：是指令开头， :q! 是不保存退出，:wq是保存后退出编辑。

新建文件夹，测试

cd /Users/yellow/Downloads/gitClient

sudo git clone yellow@192.168.0.249:/Users/yellow/Documents/gitService

测试可以再客户端输入：

git status
