OpenStack的web管理界面
1.Horizon
Horizon提供了一个web界面来操作openstack,它是基于api进行开发的,不需要连接数据库,支持群集.在我们所搭建的openstack所有的组件中,都直接或者间接的和keystone有关系,所以Horizon的安装还是让它去注册到keystone就可以了.
我们需要注意的是,openstack创建云主机的方式有三种:命令行, api, Horizon
我这里将Horizon安装在计算节点上,因为在管理节点安装keystone的时候已经安装了apache服务,避免冲突.
在计算节点上安装Horizon,就要保持计算节点和管理节点的时间一致

好了,如果是用虚拟机做实验,可以做一个快照,然后随便去点击了解web界面的功能了.
