nginx fastcgi中SCRIPT_FILENAME的设置

在官方wiki找到的

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name

在alias下路径报错

-----------------------------------------------------------------------------

fastcgi_param SCRIPT_FILENAME $request_filename

index取值忽略fastcgi_index的设定, 直接取http或者server字段下的index设定值.
