Research And Implementation Of Cluster Serverbased On Distributed Service Framework Dubbo

With the rapid development of computer network, "Internet+"industry has obtained great attention of people. The emergence of"Internet +", enable enterprises to continue to expand their business. But the impact is that software system is more and more huge, the structure of system is more and more complex and also the amount of users' visit has got a rapid growth. In this case, it is obviously not able to achieve the requirements of system when still using the traditional single server to maintain the software system. So it is of great significance to do a work on the research and development of a highly efficient and practical cluster server system which has a a clear structure and the coupling between the modules is low.Through the research on the distributed technical service framework Dubbo, Nginx+Tomcat cluster and Dubbo remote service cluster,combining with many research works of the large platform education system, this paper designs and implements a cluster server system based on Dubbo, which is applied to a developed educational platform system.The system server can be expanded, the system business structure is easy to expand, excellent to reduce the duplication of development work.In this paper, firstly, there is a study and analysis on the key technologies used in the development process. Then, based on Dubbo architecture as the main technical architecture of the system, through the analysis of the functional requirements and performance requirements of the educational system, designed the function structure and system architecture of Dubbo cluster server system. Then the design of the module of designed system has a detail introduced, those modules include mobile terminal server, web site learning system server, background management system server, Duboo remote server and the database.Third, there are some realization of main functions of the various modules of the system. Also, the work of the deployment of the server is done.At lase, some test works are done, including system function test and performance test. The test results show that the server system in this paper has achieved the expected performance and function.
