【摘要】：近年来,云计算成为IT界最备受瞩目的技术。自云计算概念引入中国以来,在国内就得到了广泛的重视。上至国家政策,下至相关企业,无不特别关注云计算。而随着云计算技术的不断发展和用户对云计算认知的不断加强,“云”正在一步步从云端走向现实。云计算近年来得到了快速发展,而虚拟化做为云计算的基石更是备受关注。使用以虚拟化为基础的管理系统成为云计算系统研究中的热门问题。虚拟化管理系统包括计算、网络和存储等主要模块,而这些都是数据中心环境下必不可少的要素。本文分析了国内外主流虚拟化的技术现状,在此基础上,设计并实现了一个基于virtualbox的分布式虚拟化管理平台。本文的主要工作包括:(1)设计并实现了分布式框架。分布式框架已消息队列为基础,在redis的基础上实现了同步和异步方式的RPC调用。并实现了多级和广播的消息路由机制,充分实现了虚拟化管理服务的健壮性和高可用性。(2)设计并实现了分布式的虚拟网络架构。包括NAT网络机制,IP指定机制以及基于端口的安全组规则。所有的网络模式下都实现了dhcp(Dynamic Host Configuration Protocol)服务,并实现了dhcp服务之间的隔离,保证dhcp广播消息不会互相干扰。(3)设计并实现了虚拟机远程管理。主要包括开机,关机,快照,远程桌面。虚拟机通过控制节点的web管理界面进行管理,实际运行在各个计算节点上。本文实现的虚拟化管理系统主要的应用于机房和IDC等数据中心的环境,结合数据中心对计算、网络、存储以及高可用的要求,在系统设计中分别从虚拟机迁移,存储支持等方面进行了设计。对在实际应用场景下的要求,测试阶段提出了详细的测试目标和科学的测试方法。
[Abstract]:In recent years, cloud computing has become the most attractive technology in IT. Since cloud computing was introduced into China, it has been paid more and more attention in China. Up to the national policy, down to the related enterprises, all pay special attention to cloud computing. With the continuous development of cloud computing technology and the continuous enhancement of users' cognition of cloud computing, "cloud" is moving from cloud to reality step by step. Cloud computing has developed rapidly in recent years, and virtualization as the cornerstone of cloud computing has attracted much attention. The use of virtualization based management systems has become a hot issue in cloud computing systems. Virtualization management system includes computing, network, storage and other main modules, which are essential elements in the data center environment. This paper analyzes the current situation of mainstream virtualization technology at home and abroad, and then designs and implements a distributed virtualization management platform based on virtualbox. The main work of this paper is as follows: (1) the distributed framework is designed and implemented. Based on the message queue, the distributed framework implements synchronous and asynchronous RPC calls on the basis of redis. The message routing mechanism of multilevel and broadcast is implemented, and the robustness and high availability of virtualization management service are fully realized. (2) the distributed virtual network architecture is designed and implemented. Including NAT network mechanism, IP specification mechanism and port-based security group rules. In all the network modes, dhcp (Dynamic Host Configuration Protocol) services are implemented, and the isolation between dhcp services is realized. (3) the remote management of virtual machine is designed and implemented to ensure that dhcp broadcast messages will not interfere with each other. Including boot, shutdown, snapshot, remote desktop. The virtual machine is managed by the web management interface of the control node and actually runs on each computing node. The virtualization management system realized in this paper is mainly applied to the environment of data center such as computer room and IDC, combined with the requirement of computing, network, storage and high availability in the data center, the virtual machine is migrated from the virtual machine in the system design. Storage support and other aspects are designed. For the requirements of practical application scenarios, the detailed test objectives and scientific testing methods are put forward in the test stage.
