wget -O /var/www/HTML/private/index.HTML
wget -O /var/www/virtual/private/index.HTML
vim /etc/httpd/conf/httpd.conf
<dirsectory "/var/www/HTML/private">
requIEr all denIEd
require local
</dirsectory>
<dirsectory "/var/www/virtual/private">
require all denIEd
require local
</dirsectory>

vim /etc/httpd/conf/httpd.conf
<virtualhost *:8909>
servername wsgi.group8.example.com
wsgiscripalias / /var/www/HTML/webinfo.wsgi
<virtualhost>

16.创建foo脚本
