因为它周期性连接到非本地缓存有问题。官网写的有bug。
* {( z7 G( I8 ]0 g" t1 R修改/etc/openstack-dashboard/local_settings.py

               把/etc/openstack-dashboard/local_settings.py  中 SESSION_ENGINE = 'django.contrib.sessions.backends.cache' 应改为
               SESSION_ENGINE = 'django.contrib.sessions.backends.file'

解决:更改dashboard的local_settings配置文件并重启httpd和memcached，刷新后可正常登陆，这是在国外的论坛上找到得解决方法。
