Git 服务器基于nginx配置http(s)协议

Git HTTP协议简介

从git官方文档上看,git实现http(s)协议有两种方式

  1. 智能(Smart)HTTP
  2. 哑(Dump)HTTP

其中Smart HTTP是自Git 1.6.6版本开始引入的一种新的、更智能的协议。基于该协议可以实现对git仓库的读写功能。而在Dump HTTP里 web 服务器仅把裸版本库当作普通文件来对待,提供文件服务,更多的是用来实现只读功能。

基于Nginx配置http(s)

安装相关依赖

Git官方文档里,配置Git server支持http协议拿的是Apache httpd举例的。经过查验,如果希望用nginx做webserver,则需要另外的fcgiwrap以及spawn-fcgi。

具体的逻辑则是:nginx若要支持git-http-backend,需要fcgiwarp的帮助。而如果希望fcgiwarp以daemon方式运行,则需要spawn-fcgi。既然知道了逻辑,那就准备开干吧。好在安装比较简单。

yum install fcgi-devel spawn-fcgi
#以上需要epel源
git clone https://github.com/gnosek/fcgiwrap.git
cd fcgiwrap
autoreconf -i
./configure
make && make install

借用github上别人写的启动脚本(详见参考资料),按照自己的实际环境,修改好放置/etc/init.d/下

}

现在,你可以使用git clone http://xxx.xxx/**.git 的方式操作了。

尾巴

若需要使用验证,可使用htpasswd生成用户名以及密码,再配置到nginx的配置文件中。若仓库接收git push时报错403,可在仓库中设置git config http.receivepack true
