在做一个使用REST API实现基于WEB的增删查改（CRUD）程序，使用lighttpd，后端
使用python。
在ubuntu上配置好lighttpd之后，浏览器输入网址，lighttpd的error.log报如下错
误，看了下感觉很困惑，而且排除了以下问题：
1. 不是权限问题，/tmp/fastcgi.socket-0权限是srwxr-xr-x 1 root root 0 May  
5 07:47 /tmp/fastcgi.socket-0
2. 不是lighttpd权限问题，因为我是root用户安装的。
3. 我修改了lighttpd程序，使得lighttpd在ubuntu上以root用户运行，即
username="root", groupname="root"
