3. 重启web,memcached服务

验证操作

打开浏览器，输入地址：http://ops-cont/dashboard

openstack-dashboard

注意

按照官方文档配置完成后，在执行登录操作的时候httpd日志会报如下错误提示：

"Unable to create a new session key. "
RuntimeError: Unable to create a new session key. It is likely that the cache is unavailable.

根据错误提示，需要修改SESSION_ENGINE,将其修改为'django.contrib.sessions.backends.file'即可正常登录。²
