OpenStack版本升级之Horizon
安装依赖库对照下面E版和F版的pip-requires比较并运行pip freeze查看已经安装的包，然后安装缺少的依赖包，另外F版还需要有nodejs支持：
$ git diff origin/stable/essex:tools/pip-requires origin/stable/folsom:tools/pip-requires
diff --git a/origin/stable/essex:tools/pip-requires b/origin/stable/folsom:tools/pip-requires

配置
我这里采用memcached来作为session的存储不再采用数据库，各种session存储方式的比较见这里
# cd openstack_dashboard/local/
# cp local_settings.py.example local_settings.py

小问题
1.Admin权限用户登录后，Admin选项卡的Volume列表的Action列没有内容
2.Admin中的Overview选项的Usage Summary和Project中的Overview选项的Usage Summary显示不正确，只能统计到更新Horizon后新建或resize的实例信息(可能是因为我将以前创建的实例关联的flavor删除了造成的)
3.Project中的Overview选项的Quota Summary显示不正确
4.英语环境下，Project的Access & Security选项的Floating IP列表的Action列宽度不够（详情）
5.访问速度比较慢！！！
