【摘要】：隨著計(jì)算機(jī)性性能越來越高,服務(wù)器的利用率反而越來越低。某互聯(lián)網(wǎng)公司在建設(shè)面向全國的商業(yè)房地產(chǎn)搜索網(wǎng)站過程中,提出了在初期以低成本的方式運(yùn)營網(wǎng)站的需求,希望通過提高服務(wù)器利用率來降低服務(wù)器采購成本和服務(wù)器托管成本。利用虛擬機(jī)實(shí)現(xiàn)服務(wù)器整合是提高服務(wù)器資源利用率的有效方法。 本文分析了網(wǎng)站業(yè)務(wù)的具體需求,并通過對比說明基于虛擬機(jī)的服務(wù)器整合的優(yōu)勢：不僅可以提高資源利用率,而且能夠通過增加硬件設(shè)施的方式不斷滿足網(wǎng)站業(yè)務(wù)持續(xù)增長的需求。分析了服務(wù)器整合中的關(guān)鍵問題及應(yīng)對措施,針對網(wǎng)站服務(wù)器整合方案設(shè)計(jì),探討了虛擬化產(chǎn)品選型和硬件平臺建設(shè)等問題。 本文為該網(wǎng)站設(shè)計(jì)實(shí)現(xiàn)了一套基于虛擬機(jī)的網(wǎng)站服務(wù)器整合方案,并針對平臺選型、相容性部署、單點(diǎn)失效、負(fù)載均衡、性能優(yōu)化等問題,介紹了如何通過合理配置與自動化控制,對網(wǎng)站服務(wù)持續(xù)、高效、可靠地運(yùn)行提供保障。所實(shí)現(xiàn)的虛擬機(jī)自動化部署管理、無中斷系統(tǒng)升級管理、自動化的系統(tǒng)監(jiān)控與維護(hù)和自適應(yīng)的性能調(diào)節(jié)和優(yōu)化的備份與恢復(fù)機(jī)制,有力的支撐并保證了網(wǎng)站系統(tǒng)的平穩(wěn)運(yùn)行。 利用虛擬機(jī)實(shí)現(xiàn)網(wǎng)站整合將成為中小互聯(lián)網(wǎng)網(wǎng)站和初創(chuàng)互聯(lián)網(wǎng)網(wǎng)站建設(shè)的最重要的整合技術(shù),隨著云計(jì)算技術(shù)的不斷發(fā)展和基礎(chǔ)設(shè)施云服務(wù)的成熟,越來越多的網(wǎng)站將運(yùn)行在虛擬機(jī)中而不是直接運(yùn)行在物理服務(wù)器之上。
[Abstract]:With the higher and higher performance of the computer, the utilization rate of the server is getting lower and lower. A certain Internet company is building a commercial real estate search website facing the whole country. Put forward the need to operate the website in a low cost way in the early stage. It is hoped that server purchasing cost and server hosting cost can be reduced by increasing server utilization, and server integration with virtual machine is an effective method to improve server resource utilization. This paper analyzes the specific requirements of the website business, and shows the advantages of server integration based on virtual machine: it can not only improve the utilization of resources. And through increasing the hardware facilities to meet the continuous growth of website business needs. This paper analyzes the key problems and countermeasures in server integration, aiming at the design of website server integration scheme. The selection of virtualization products and the construction of hardware platform are discussed. This paper designs and implements a set of web server integration scheme based on virtual machine, aiming at platform selection, compatibility deployment, single point failure, load balancing, performance optimization and so on. This paper introduces how to provide guarantee for the continuous, efficient and reliable operation of website service through reasonable configuration and automation control. The automatic deployment management of virtual machine and the upgrade management of system without interruption are realized. Automatic system monitoring and maintenance, adaptive performance adjustment and optimized backup and recovery mechanism support and ensure the smooth operation of the website system. Using virtual machine to achieve website integration will become the most important integration technology for the construction of medium and small Internet sites and start-up Internet sites. With the continuous development of cloud computing technology and the maturity of infrastructure cloud services. More and more websites will run in virtual machines rather than directly on physical servers.
