OpenStack介绍
OpenStack是一种免费的开源平台，帮助服务提供商实现类似于亚马逊EC2和S3的基础设施服务。OpenStack当前有三个核心项目：计算(Nova)，对象存储(Swift)，镜像管理(Glance)。每个项目可以独立安装运行，该文档将帮助您快速学习OpenStack。
OpenStack背景现状
OpenStack是由Rackspace Cloud和NASA（美国航天局）于2010年7月开始共同开发支持，整合了Rackspace的Cloud Files platform和NASA的Nebula platform技术，目的是能为任何一个组织创建和提供云计算服务。
目前，超过150家公司参与了这个项目，包括Crtrix Systems, Dell, AMD, Intel, Cisco, HP等。 OpenStack最近发布了Austin产品，它是第一个开源的云计算平台，它是基于Rackspace的云服务器加上云服务，以及NASA的Nebula技术发布的。似乎是作为对此的响应，Amazon为新用户提供一年的AWS免费使用方式。在OpenStack发布Austin之后，微软也宣称Windows Server 2008 R2 Hyper-V可以与OpenStack整合。微软会为http://www.360docs.net/doc/info-1edcde5bcc22bcd127ff0c0f.html 提供架构和技术上的指引，它会编写必要的代码，从而OpenStack能够在微软的虚拟平台上运行。这些代码会在http://www.360docs.net/doc/info-1edcde5bcc22bcd127ff0c0f.html 上提供。
OpenStack是什么？及OpenStack核心项目
OpenStack是一种免费的开源平台，帮助服务提供商实现类似于亚马逊EC2和S3的基础设施服务。OpenStack当前有三个核心项目：计算(Nova)，对象存储(Swift)，镜像管理(Glance)。每个项目可以独立安装运行。另外还有两个新增项目：身份验证(Keystone)和仪表盘(Horizon)。
OpenStack计算是一个云控制器，用来启动一个用户或一个组的虚拟实例，它也用于配置每个实例或项目中包含多个实例为某个特定项目的联网。
OpenStack对象存储是一个在具有内置冗余和容错的大容量系统中存储对象的系统。对象存储有各种应用，如备份或存档数据，存储图形或视频（流媒体数据传输到用户的浏览器），储存二级或三级静态数据，发展与数据存储集成新的应用程序，当预测存储容量困难时存储数据，创造弹性和灵活的云存储Web应用程序。
OpenStack镜像服务是一个查找和虚拟机图像检索系统。它可以配置三种方式：使用OpenStack对象存储来存储图像;使用亚马逊S3直接存储，或使用S3对象存储作为S3访问中间存储。
目前为止共有五个版本：
1. Austin
2. Bexar
3. Cactus
4. Diablo
5. Mitaka
OpenStack 功能
  OpenStack能帮我们建立自己的IaaS，提供类似Amazon Web Service的服务给用户：
1、普通用户可以通过它注册云服务，查看运行和计费情况
2、开发和运维人员可以创建和存储他们应用的自定义镜像，并通过这些镜像启动、监控和、平台的管理人员能够配置和操作网络，存储等基础架构。
OpenStack的优势是平台分模块化，由每个独立的组件组成，每个nova组件都可以单独安装在独立的服务器上，各个组件之间不共享状态，各个组件之间通过消息队列(MQ)来进行异步通讯。也可以通过选用合适组件来定制个性化服务，便于应用改进。使用apache协议可以支持企业使用。
OpenStack架构
Compute(Nova)的软件架构，每个nova-xxx组件是由python代码编写的守护进程，每个进程之间通过队列（Queue）和数据库（nova database）来交换信息，执行各种请求。而用户通过nova-api暴露的web service来同其他组件进行交互。Glance是相对独立的基础架构，nova通过glance-api来和它交互。
Nova组件的作用 nova-api是Nova的中心。它为所有外部调用提供服务，除了提供OpenStack本身的API规范外，他还提供了兼容EC2的部分API，所以也可以用EC2的管理工具对nova进行日常管理。nova-compute负责对虚拟机实例进行创建、终止、迁移、Resize的操作。工作原理可以简单描述为：从队列中接收请求，通过相关的系统命令执行他们，再更新数据库的状态。nova-volume管理映射到虚拟机实例的卷的创建、附加和取消。nova-network从队列中接收网络任务，然后执行任务控制虚拟机的网络，比如创建桥接网络或改变iptables的规则。nova-scheduler 提供调度，来决定在哪台资源空闲的机器上启动新的虚拟机实例Queue为守护进程传递消息。只要支持AMQP协议的任何Message Queue Sever都可以，当前官方推荐用RabbitMQ。SQL database存储云基础架构中的各种数据。包括了虚拟机实例数据，网络数据等。
user dashboard是一个可选的项目。它提供了一个web界面来给普通用户或者管理者来管理、配置他们的计算资源。
所有的计算节点需要和控制节点进行镜像交互，网络交互，控制节点是整个架构的瓶颈，这种配置主要用于概念证明或实验环境。多节点：增加节点单独运行nova-volume，同时在计算节点上运行nova-network，并且根据不同的网络硬件架构选择DHCP或者VLan模式，让控制网络和公共网络的流量分离。
OpenStack在企业中的应用
更多的企业不只是谈论OpenStack，而是在实际生产环境中部署它，包括Rackspace基于Puppet的公有云。OpenStack自研发伊始，一直被视作云计算领域的Linux，其推动开放源代码服务的努力得到了众多公司的支持。目前就有超过100个机构参与了代码库的建设，或在其它方面参与该项目。新浪云计算将与OpenStack一起合力打造一套可以管理和配置各种虚拟化技术的IaaS平台，在开源代码库的建设方面将有着不小的贡献。

[iyunv@open-node1 ~] # yum install mysql-server
[iyunv@open-node1 ~] # cp /usr/share/mysql/my-medium.cnf  /etc/my.cnf
[iyunv@open-node1 ~] #vim /etc/my.cnf
增加以下配置”

[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

[iyunv@open-node1 ~] # chkconfig mysqld on
[iyunv@open-node1 ~] # /etc/init.d/mysqld start
3.1.2 数据库的安装

[iyunv@open-node1 ~] # mysql –u root
mysql>show databases;

3.1.3 创建keystone数据库并授权

　　mysql> create database keystone;
mysql> grant all on keystone.* to keystone@'192.168.56.0/255.255.255.0' identified by 'keystone';
3.1.4 创建glance数据库并授权
　　mysql> create database glance;

　　显示：
　　| Database          |
+--------------------+
| information_schema |
| cinder          |
| glance          |
| keystone          |
| mysql             |
| neutron          |
| nova             |
| test             |
+--------------------+
8 rows in set (0.00 sec)
　　3.2 消息代理服务RabbitMQ
3.2.1 RabbitMQ
3.2.2 RabbitMQ安装
mysql> \q
[iyunv@open-node1 ~]# yum -y install ncurses-devel

5.7 测试Glance
Glance。一套虚拟机镜像查找及检索系统，支持多种虚拟机镜像格式（AKI、AMI、ARI、ISO、QCOW2、Raw、VDI、VHD、VMDK），有创建上传镜像、删除镜像、编辑镜像基本信息的功能。自Bexar版本集成到项目中。
作为IaaS的存储服务与OpenStack Compute对接，为其存储镜像文档存储存储需要长期保存的数据，例如log 存储网站的图片，缩略图等
OpenStack项目架构三 – Glance架构
OpenStack镜像服务提供OpenStack Nova虚拟机镜像的发现，注册，取得服务。通过Glance，虚拟机镜像可以被存储到多种存储上，比如简单的文件存储或者对象存储（比如OpenStack中swift项目）。
Glace组件架构
· Glance目前提供的参考实现中Registry Server仅是使用Sql数据库存储metadata。
· 前端通过API Server向多个Client提供服务。
· 可以使用多种后端存储。Glance目前支持S3，Swift，简单的文件存储及只读的HTTPS存储。
· 后续也可能支持其他后端，如分布式存储系统（SheepDog或Ceph） Glace组件架构特性
1.基于组件的架构：便于快速增加新特性
2.高可用性：支持大负荷
3.容错性：独立的进程避免串行错误
4.开放标准：对社区驱动的API提供参考实现
OpenStack功能
1、 Dashboard提供资源池管理功能, 通过资源池的方式对物理资源进行重新组织。
2、提供基于命令行的虚拟机在线迁移功能，拟机生命周期管理，例如创建、启
动、休眠、唤醒、关闭、迁移、销毁虚拟机。
3、将常用的运行环境保存为虚拟机模板，可以方便地创建一系列相同或者是相
似的运行环境，只能手动创建所需用户模板，类似Eucalyptus。
4、在计算资源允许的情况下提供高可用性、动态负载均衡、备份与恢复
5、对所有的物理机和虚拟机进行监控，生成报表并在必要的情况下发出预警，
监控和报表功能据说可以采用外围组件实现
　　5.7.1 在keystone中注册glance

5.7.2  glance的镜像测试
下载一个镜像
[iyunv@openstack-node1 ~]# wget https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img
然后上传
[iyunv@openstack-node1 ~]# glance image-create --name "cirros-0.3.0-x86_64" --disk-format qcow2 --container-format bare --is-public True --file cirros-0.3.0-x86_64-disk.img
下图列出了该镜像的元数据

镜像保存是以镜像的ID保存
　　
6 Compute Services (Nova)
Nova。一套控制器，用于为单个用户或使用群组管理虚拟机实例的整个生命周期，根据用户需求来提供虚拟服务。负责虚拟机创建、开机、关机、挂起、暂停、调整、迁移、重启、销毁等操作，配置CPU、内存等信息规格。自Austin版本集成到项目中。
Nova功能介绍用户通过访问horizon(dashboard)请求资源，horizon会调用nova-api。OpenStack首先对用户进行身份认证，这个功能通过keystone模块来完成。然后通过任务调度器(nova-scheduler)确定在哪一个计算节点上创建新的虚拟机。所有的任务都会通过MQ来进行异步通讯。
云管理员用户也可以通过Euca2ools来管理和创建虚拟机，因为OpenStack支持EC2和S3接口。
OpenStack项目架构二: Swift架构
OpenStack Object Storage（Swift）是OpenStack开源云计算项目的子项目之一。前身是Rackspace Cloud Files项目。OpenStack对象存储是一个在具有内置冗余和容错的大容量系统
中存储对象的系统。对象存储有各种应用，如备份或存档数据，存储图形或视频，储存二级或三级静态数据，发展与数据存储集成新的应用程序，当预测存储容量困难时存储数据，创造弹性和灵活的云存储Web应用程序。
Swift功能
Swift使用普通的服务器来构建冗余的、可扩展的分布式对象存储集群，存储容量可达PB级。 Swift提供的服务与AWS S3相同，可以用以下用途：
Openstack创建instance的流程 1. 用户向nova-api发送请求
用户发送请求到nova-api,这里有两种：
a.通过openstack api
从server.py's controller.create():
然后就进入等待直到instance的状态变为running.
a. networker 分配ip
　　在控制节点安装时，需要安装除了nova-compute之外的其他的所有nova服务。
