openstack dnshboard安裝配置 openstack實驗環境搭建 openstack vnc網面訪問

做為專業運維人員，使用命令行工具去管理雲主機是沒有問題的，但如果雲要提供給客戶使用，就不可能讓用戶命令行工具去管理自己的雲主機了，此時，就需要一個簡單易用的管理頁面提供給用戶了，openstack官方也很體貼的為我們已經準備好了，只是程序代碼方面還存在著一些小問題，不過我已經幫大家趟過一連坑了，按照如下的配置流程是可以讓大家體驗到使用鼠標管理雲主機的效果的。

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來保存會話，但代碼有誤，所以只能先改用file保存侍會話
