tinycore linux下lighttpd+fsatcgi(flup)+web.py遇到的问题

    lighttpd的chroot方式比较安全，可在简单使用的情况下采用server.chroot方式。
    如果lighttpd使用chroot目录，则实机系统下的目录结构、环境变量将不可用。不作处理的话，lighttpd启动时会找不到脚本,提示child exited with status 2。
    提示child exited with status 1则是脚本找到了，但执行过程中出错，比如flup(是web.py的fastcgi实现)未安装导致出错，或脚本本身语法逻辑等出错。或者是脚本第一行的解释器有误，可用env命令模拟环境(#!/usr/bin/env python)，或直接写为#!/usr/local/bin/python.
    提示child exited with status 127错误，是py脚本使用了 windows换行符，重存为unix换行符即可。
    lighttpd的fastcgi设置中，fastcgi.server = ( "myweb.py" =>中的myweb.py位置必须是脚本名，否则显示为403 Forbidden错误。
    web.py和flup(用fastcgi就必须装)的安装脚本，和自定义的目录结构：
srcdir="/mnt/sda7/tinycore/lighttpd.web.py"
cd $srcdir;tar xvf flup-1.0.2.tar.gz -C /opt/www/tmp;
cd /opt/www/tmp/flup-1.0.2;sudo python setup.py install;

cd $srcdir;tar xvf web.py-0.36.tar.gz -C /opt/www/tmp;
cd /opt/www/tmp/web.py-0.36;sudo python setup.py install;

#cd $srcdir;tar xvf wsgilog-0.3.tar.bz2 -C /opt/www/tmp;
#cd /opt/www/tmp/wsgilog-0.3;sudo python setup.py install;

webroot="/opt/www/htdocs/";
sudo mkdir -p ${webroot}/static;sudo mkdir -p /opt/www/tmp;
sudo chmod 777 ${webroot} ${webroot}/static /opt/www/tmp ;

cp_cmd="sudo cp -Lprf /usr/local/share/lighttpd/lighttpd.conf.fastcgi /etc/lighttpd.conf"
if [ ! -f /etc/lighttpd.conf ];then $cp_cmd;fi;
if [ ! "`cat /etc/lighttpd.conf|grep -v "#"|grep -i fastcgi.server`" ];then $cp_cmd;fi;
sudo cp -prf $srcdir/*.py ${webroot}/;
chmod 777 ${webroot}/*.py ;

  带fastcgi的lighttpd.conf:
