【摘要】：隨著網(wǎng)絡(luò)技術(shù)和Internet的快速發(fā)展,當(dāng)今的計算機世界已經(jīng)進入了一個以網(wǎng)絡(luò)計算為中心的時代,瀏覽器/服務(wù)器模型以其簡單性、易維護性、易擴展性而在網(wǎng)絡(luò)中被大量的使用,大量的網(wǎng)絡(luò)服務(wù)和應(yīng)用如:電子商務(wù)、新聞資訊、視頻娛樂等都圍繞著Web而展開,巨大數(shù)量的Internet用戶和網(wǎng)絡(luò)流量一方面推動著應(yīng)用于Web開發(fā)的Web應(yīng)用框架技術(shù)的不斷革新,另一方面也給服務(wù)器端的數(shù)據(jù)處理能力、帶寬和服務(wù)的穩(wěn)定性帶來了嚴(yán)峻的挑戰(zhàn)。對于大規(guī)模的Web應(yīng)用而言,僅僅依靠一些優(yōu)秀的企業(yè)級應(yīng)用開發(fā)框架,只能解決企業(yè)適應(yīng)業(yè)務(wù)的快速變化和快速開發(fā)的需要,但是,如何建立一套高可用、高性價比、高性能、易管理的網(wǎng)絡(luò)服務(wù)器平臺,來解決服務(wù)器端的瓶頸問題,是目前人們正在努力解決的問題。綜合運用集群和負(fù)載均衡技術(shù)就是一種很好的解決方案,所以近年來服務(wù)器集群技術(shù)在Web應(yīng)用中得了廣泛的應(yīng)用。本文首先對基于負(fù)載均衡的Web服務(wù)器集群技術(shù)進行了研究,對主流的Web服務(wù)器集群技術(shù)進行了比較、歸納,研究了Linux虛擬服務(wù)器(LVS)系統(tǒng)的內(nèi)部架構(gòu)和特點。其次為解決公司內(nèi)部的服務(wù)器管理問題,設(shè)計并開發(fā)一套服務(wù)器運營維護管理系統(tǒng)。該系統(tǒng)基于J2EE平臺,采用B/S(Browser/Server)模式,使用開源的SpringMVC框架,數(shù)據(jù)庫使用MySQL“主-從”數(shù)據(jù)庫策略,使服務(wù)器端的讀寫分離,保證服務(wù)器端的數(shù)據(jù)一致性和高穩(wěn)定性。由于該系統(tǒng)的使用量相當(dāng)大,為使系統(tǒng)的網(wǎng)絡(luò)架構(gòu)能保證大量用戶同時使用時,系統(tǒng)仍然能提供正常服務(wù),本文探索出了一套廉價且可用的解決方案,提出使用LVS進行服務(wù)器端負(fù)載均衡,搭建一個具有負(fù)載均衡性能的服務(wù)器群組,以保證系統(tǒng)具有處理高并發(fā)、高流量的性能需求。最后經(jīng)測試結(jié)果表明,該方案能有效的解決系統(tǒng)面臨的大并發(fā)、高流量的問題,很好的實現(xiàn)了集群負(fù)載均衡的效果。該系統(tǒng)在實際使用中已經(jīng)歷了上萬人次的使用檢驗,并可以處理300人峰值訪問的性能需求。
[Abstract]:With the rapid development of network technology and Internet, the computer world has entered an era centered on network computing. The browser / server model is widely used in the network because of its simplicity, maintainability and expansibility. A large number of network services and applications such as: electronic commerce, news information, video entertainment and so on are developed around Web. On the one hand, a huge number of Internet users and network traffic promote the continuous innovation of Web application framework technology applied to Web. On the other hand, it also brings serious challenges to the data processing ability, bandwidth and service stability of the server. For large-scale Web applications, only relying on some excellent enterprise application development framework can only meet the needs of rapid business changes and rapid development. However, how to establish a set of high availability, high performance and high performance, Easy to manage the network server platform, to solve the server side of the bottleneck problem, is currently trying to solve the problem. The application of cluster and load balancing technology is a good solution, so server cluster technology has been widely used in Web applications in recent years. This paper firstly studies the Web server cluster technology based on load balancing, compares the mainstream Web server cluster technology, and summarizes the internal structure and characteristics of Linux virtual server (LVS) system. Secondly, in order to solve the problem of server management, a server operation and maintenance management system is designed and developed. The system is based on J2EE platform, adopts B / S (Browser/Server) mode, uses open source SpringMVC framework, and uses MySQL "master-slave" database strategy, which makes the server read and write separately, and ensures the data consistency and high stability of the server. Because the usage of the system is very large, in order to make the network architecture of the system ensure that a large number of users can use it simultaneously, the system can still provide normal service, so this paper explores a set of cheap and available solutions. This paper proposes to use LVS to balance the load on the server side and build a server group with load balancing performance to ensure that the system has the performance requirement of dealing with high concurrency and high traffic. Finally, the test results show that this scheme can effectively solve the problem of large concurrency and high traffic, and achieve the effect of load balancing. The system has experienced tens of thousands of usage tests in actual use and can handle the performance requirements of 300 peak access.
