openstack安装配置—— dnshboard安装配置
做为专业运维人员，使用命令行工具去管理云主机是没有问题的，但如果云要提供给客户使用，就不可能让用户命令行工具去管理自己的云主机了，此时，就需要一个简单易用的管理页面提供给用户了，openstack官方也很体贴的为我们已经准备好了，只是程序代码方面还存在着一些小问题，不过我已经帮大家趟过一连坑了，按照如下的配置流程是可以让大家体验到使用鼠标管理云主机的效果的。安装并修改配置文件

修正方法：
修改dashboard配置文件的SESSION_ENGINE方式
SESSION_ENGINE = ‘django.contrib.sessions.backends.file‘
官方配置是用memcached来保存会话，但代码有误，所以只能先改用file保存侍会话

至此，一套简单的openstack实验环境搭建完成，不足之处，还望大牛指点。与此同时，也非常希望有正在学习openstack的同仁能够相互交流，如有留言告之或者直接添加公告上联系方式。
