解决办法：

curl http://git.openstack.org/cgit/openstack/keystone/plain/httpd/keystone.py?h=stable/kilo | tee /var/www/cgi-bin/keystone/main /var/www/cgi-bin/keystone/admin

// 由于该网页不再提供支持所以无法下载到该文件了
// 大家可以访问以下

解决办法：

（一）
cd /usr/share/keystone/

cp keystone.wsgi /var/www/cgi-bin/keystone/admin
cp keystone.wsgi /var/www/cgi-bin/keystone/main

（二）
或者在 /var/www/cgi-bin/keystone/文件夹下新建admin和main文件
