下面说一说Openstack的各个组件作用及关系 Openstack发展至今,总共集成了下面几个组件:
Nova - 计算加拿大28开奖官网 Neutron-网络加拿大28开奖官网 Swift - 对象存储加拿大28开奖官网 Cinder-块存储加拿大28开奖官网 Glance - 镜像加拿大28开奖官网 Keystone - 认证加拿大28开奖官网 Horizon - UI加拿大28开奖官网 Ceilometer-监控加拿大28开奖官网 Heat-集群加拿大28开奖官网 Trove-数据库加拿大28开奖官网 组件间的关系图如下: 重要组件介绍 OpenStack认证加拿大28开奖官网(Keystone) Keystone为所有的OpenStack组件提供认证和访问策略加拿大28开奖官网,它依赖自身REST(基于Identity API)系统进行工作,主要对(但不限于)Swift、Glance、Nova等进行认证与授权。事实上,授权通过对动作消息来源者请求的合法性进行鉴定。下图显示了身份认证加拿大28开奖官网流程: Keystone采用两种授权方式,一种基于用户名/密码,另一种基于令牌(Token)。

2)glance-registry:   

主要负责接收响应镜像元数据命令的Restful请求。分析消息请求信息并分发其所带的命令(如获取元数据,更新元数据等)。默认绑定的端口是9191。 OpenStack存储设施----Swift Swift为OpenStack提供一种分布式、持续虚拟对象存储,它类似于Amazon Web Service的S3简单存储加拿大28开奖官网。Swift具有跨节点百级对象的存储能力。Swift内建冗余和失效备援管理,也能够处理归档和媒体流,特别是对大数据(千兆字节)和大容量(多对象数量)的测度非常高效。
swift功能及特点:    海量对象存储 大文件(对象)存储 数据冗余管理 归档能力-----处理大数据集 为虚拟机和云应用提供数据容器 处理流媒体 对象安全存储 备份与归档 良好的可伸缩性 Swift组件 Swift账户 Swift容器 Swift对象 Swift代理 Swift RING   
Swift代理加拿大28开奖官网器   用户都是通过Swift-API与代理加拿大28开奖官网器进行交互,代理加拿大28开奖官网器正是接收外界请求的门卫,它检测合法的实体位置并路由它们的请求。 此外,代理加拿大28开奖官网器也同时处理实体失效而转移时,故障切换的实体重复路由请求。 Swift对象加拿大28开奖官网器 对象加拿大28开奖官网器是一种二进制存储,它负责处理本地存储中的对象数据的存储、检索和删除。对象都是文件系统中存放的典型的二进制文件,具有扩展文件属性的元数据(xattr)。 注意: xattr格式被Linux中的ext3/4,XFS,Btrfs,JFS和ReiserFS所支持,但是并没有有效测试证明在XFS,JFS,ReiserFS,Reiser4和ZFS下也同样能运行良好。不过,XFS被认为是当前最好的选择。 Swift容器加拿大28开奖官网器 容器加拿大28开奖官网器将列出一个容器中的所有对象,默认对象列表将存储为SQLite文件(译者注: 也可以修改为MySQL,安装中就是以MySQL为例)。容器加拿大28开奖官网器也会统计容器中包含的对象数量及容器的存储空间耗费。 Swift账户加拿大28开奖官网器 账户加拿大28开奖官网器与容器加拿大28开奖官网器类似,将列出容器中的对象。 Ring(索引环) Ring容器记录着Swift中物理存储对象的位置信息,它是真实物理存储位置的实体名的虚拟映射,类似于查找及定位不同集群的实体真实物理位置的索引加拿大28开奖官网。这里所谓的实体指账户、容器、对象,它们都拥有属于自己的不同的Rings。 OpenStack管理的Web接口----Horizon
Horizon是一个用以管理、控制OpenStack加拿大28开奖官网的Web控制面板,它可以管理实例、镜像、创建密匙对,对实例添加卷、操作Swift容器等。除此之外,用户还可以在控制面板中使用终端(console)或VNC直接访问实例。

加拿大28开奖官网 zongzhi,horizonjuyouruxiayixietedian:  

  实例管理: 创建、终止实例,查看终端日志,VNC连接,添加卷等 访问与安全管理: 创建安全群组,管理密匙对,设置浮动IP等 偏好设定: 对虚拟硬件模板可以进行不同偏好设定 镜像管理: 编辑或删除镜像 查看加拿大28开奖官网目录 管理用户、配额及项目用途 用户管理: 创建用户等 卷管理: 创建卷和快照 对象存储处理: 创建、删除容器和对象 为项目下载环境变量
