【摘要】：隨著信息化在各行各業(yè)的企業(yè)中的推廣,尤其是web應(yīng)用在各個(gè)行業(yè)中的應(yīng)用,日益增長(zhǎng)的用戶訪問對(duì)企業(yè)的信息建設(shè)提出來(lái)越來(lái)越嚴(yán)重的挑戰(zhàn),這使得服務(wù)器端必須有效應(yīng)對(duì)急劇擴(kuò)大的訪問量,保持應(yīng)對(duì)大量并發(fā)訪問服務(wù)的能力。 伴隨著負(fù)載均衡技術(shù),虛擬化和云計(jì)算技術(shù)的應(yīng)用,服務(wù)器端在處理性能上得到了很大的提高,但是網(wǎng)絡(luò)的接入層始終是系統(tǒng)的瓶頸。近年來(lái),Nginx服務(wù)器作為反向代理服務(wù)器在網(wǎng)絡(luò)接入層應(yīng)用比較廣泛,Nginx的主要功能之一根據(jù)配置將用戶的請(qǐng)求轉(zhuǎn)發(fā)到后端的服務(wù)器集群中,對(duì)于簡(jiǎn)單的服務(wù)器集群環(huán)境,Nginx表現(xiàn)良好,但是當(dāng)后端服務(wù)器集群環(huán)境比較復(fù)雜時(shí),例如服務(wù)器性能不同,服務(wù)器應(yīng)用程序的開銷不同時(shí),Nginx系統(tǒng)會(huì)存在一些列問題,Nginx系統(tǒng)無(wú)法有效的監(jiān)控后端服務(wù)器集群資源,無(wú)法根據(jù)服務(wù)器的開銷智能地分發(fā)用戶的訪問量,使服務(wù)器的處理性能和工作量相適應(yīng)。 為了解決上述問題,本文結(jié)合在實(shí)際項(xiàng)目中的研究成果,設(shè)計(jì)和實(shí)現(xiàn)了一種基于Nginx系統(tǒng)的智能調(diào)度管理方案,能夠靈活的根據(jù)后端服務(wù)器的負(fù)載狀況智能的轉(zhuǎn)發(fā)用戶的請(qǐng)求,并且通過實(shí)驗(yàn)數(shù)據(jù)對(duì)比,證明了該策略能夠充分利用服務(wù)器的性能,使得服務(wù)器的處理性能和工作量相適應(yīng),本文涉及到的研究?jī)?nèi)容如下： 1.深入研究了當(dāng)前方向代理領(lǐng)域的背景和Nginx服務(wù)器核心內(nèi)容,包括Nginx的架構(gòu),工作原理和相關(guān)技術(shù)。 2.提出了基于Nginx的智能調(diào)度管理系統(tǒng)的設(shè)計(jì)方案,并詳細(xì)闡述了這樣設(shè)計(jì)的依據(jù)和實(shí)現(xiàn)的詳細(xì)過程。 3.實(shí)現(xiàn)了系統(tǒng)原型,并且通過該系統(tǒng)的性能分析驗(yàn)證了智能管理系統(tǒng)的有效性。
[Abstract]:With the popularization of information technology in enterprises in various industries, especially the application of web in various industries, the increasing number of users visiting brings out more and more serious challenges to the information construction of enterprises. This makes it necessary for the server to respond effectively to the rapidly expanding traffic and to maintain the ability to cope with a large number of concurrent access services. With the application of load balancing technology, virtualization and cloud computing technology, the processing performance of server has been greatly improved. However, the network access layer is always the bottleneck of the system. In recent years, Nginx server has been widely used in the network access layer as one of the main functions of the reverse proxy server. Nginx performs well for a simple server cluster environment, but when the back-end server cluster environment is complex, for example, server performance is different. There are some column problems in Nginx system with different application overhead. Nginx system can not effectively monitor the back-end server cluster resources, and can't intelligently distribute users' visits according to the cost of the server. Makes the server processing performance and workload appropriate. In order to solve the above problems, this paper designs and implements an intelligent scheduling management scheme based on Nginx system, which can transmit user requests intelligently according to the load condition of back-end server. And through the comparison of experimental data, it is proved that the strategy can make full use of the performance of the server, make the server processing performance and workload to adapt. The research contents of this paper are as follows:. 1. The background of the current proxy field and the core content of the Nginx server, including the architecture, working principle and related technologies of the Nginx are deeply studied. 2. The design scheme of intelligent dispatching management system based on Nginx is put forward, and the basis of this design and the detailed process of realization are described in detail. 3. The prototype of the system is implemented, and the effectiveness of the intelligent management system is verified by the performance analysis of the system.
