【摘要】：近些年隨著云計算技術(shù)的快速發(fā)展,各種云服務供應商不斷增多,國內(nèi)各個公司的云平臺服務呈現(xiàn)出競爭激烈的趨勢,提供的資源服務種類也變得多種多樣,極大的縮短了普通用戶和云端資源的距離,帶來良好的經(jīng)濟效益。但是目前這些云服務供應商的商業(yè)服務都是收費的,用戶申請的資源配置越好所產(chǎn)生的服務費用也就越高,而且當前面向?qū)W校、科研機構(gòu)等社會組織的免費開源的云平臺較少。 本論文在充分研究CVM, Libvirt虛擬化技術(shù)的基礎(chǔ)上,利用高效的Nginx, Tornado非阻塞服務器和各種Web技術(shù),實現(xiàn)了一個免費開源的在線虛擬化云平臺Jupiter,為廣大校園用戶免費提供虛擬專用服務器(VPS)租用,在線資源管理等常用服務。在云平臺中充分利用GlusterFS分布式文件系統(tǒng)為平臺提供了充足和快速的存儲空間,并且對GlusterFS文件系統(tǒng)的訪問速度進行了詳細測試。設(shè)計了WebSSH的虛擬機訪問方式,實現(xiàn)了虛擬機的在線管理和訪問。通過KVM的性能優(yōu)化措施提高了虛擬機的整體性能。設(shè)計了Nginx和Tornado服務器的配合使用方案來提高云平臺的并發(fā)訪問效率,以及重構(gòu)工程代碼以使Tornado的非阻塞特性發(fā)揮更好的性能。目前部署在校園網(wǎng)絡中心的虛擬化云平臺運行穩(wěn)定,實現(xiàn)了系統(tǒng)的設(shè)計目標,極大的解決了在校師生的科研和個人云資源需求。
[Abstract]:In recent years, with the rapid development of cloud computing technology, the number of cloud service providers is increasing. The cloud platform services of domestic companies show a trend of fierce competition, and the types of resource services are also becoming various. It greatly shortens the distance between ordinary users and cloud resources and brings good economic benefits. But at present, the commercial services of these cloud service providers are charged, and the better the allocation of resources applied by users, the higher the cost of services. And there are few free open-source cloud platforms for schools, research institutions and other social organizations. Based on the full research of CVM, Libvirt virtualization technology, this paper uses efficient Nginx, Tornado non-blocking server and various Web technologies. A free open source online virtualization cloud platform, Jupiter, is implemented, which provides free VPS-based virtual private server rental for the vast number of campus users. Make full use of GlusterFS distributed file system in the cloud platform to provide sufficient and fast storage space for the platform. The access speed of GlusterFS file system is tested in detail. The virtual machine access mode of WebSSH is designed. The online management and access of virtual machine are realized. The overall performance of virtual machine is improved by KVM performance optimization measures. The scheme of Nginx and Tornado server is designed to improve the concurrent access efficiency of cloud platform. And refactoring the engineering code to make Tornado's non-blocking feature play a better performance. At present, the virtualized cloud platform deployed in the campus network center runs stably, and realizes the design goal of the system. It greatly solves the need for scientific research and personal cloud resources of teachers and students.
