环境是centos7，直接跑在服务器上。
按照官网一步步安装openstack，到验证dashborad时出错。

意思大概是:
因为它周期性连接到非本地缓存有问题。官网写的有bug。
把/etc/openstack-dashboard/local_settings 中 SESSION_ENGINE = ‘django.contrib.sessions.backends.cache‘ 应改为
SESSION_ENGINE = ‘django.contrib.sessions.backends.file‘
重启服务，然后重新登录成功。
以上是我在部署openstack过程中遇到的几个疑问点，可能“乱拳打死老师傅”一般避开了各位的疑难点，各位可在留言中向我提问,愿意向各位讨教！----yh
