| In recent years,thanks to the continuous progress of Internet related technology and the emergence of cloud computing,cloud storage has gradually occupied an increasing proportion in today’s information storage.In addition,because the Internet has played an increasingly important role in people’s daily life,the technology has also expanded its scale.So nowadays,we have more and more requirements for the operation of the server’s numerical information.In all kinds of data processing technology,because of low cost and high adaptability,server cluster technology is particularly prominent,and has been widely adopted and applied.This research is mainly focused on the application of clustering technology in cloud storage of video files,and the specific implementation of cloud storage is designed.In addition,in order to better solve the large number of service requirements in the network,we have constructed a relatively high applicability of the cluster system.The main content of this project is about the construction part of a server cluster system.Based on cloud storage,the system collectively set up many target servers through cluster technology.At the same time,the cluster system used load balancing technology to deal with the service demand information from various terminals reasonably,and ensured the practicability of the system through the use of backup servers,and at the same time,it had good transparency and expansibility.The main work is as follows:1.build a cloud storage system.The cluster system we have built is mainly based on the storage function,and the function is also the core part.The cluster system stores information and data transmitted by various device terminals by using disk array technology,and builds video pools,and then classifies and stores received information.2.build the server cluster.The design of the main components of the cluster system is mainly carried out,including the specific interaction mode in the system,the information transmission module API in the server and the external environment,and even for the server’s monitoring device.And the load information of the server is dealt with in detail,and the information transmission function of the management server module is realized.3.cluster load balancing scheduling.Based on a balanced load scheduling strategy,a specific processing function of the operation processing information sent to the device terminal is performed.The system we built mainly used the following algorithms: source address hashing,dynamic feedback,weighted polling and so on to ensure that the designed system has better performance.4.high availability cluster system.A standby server device is built to monitor the specific status information of the management server,and the two servers share the same numerical information content.So if the management server is unable to work,the standby server can start immediately.Therefore,the system has a higher fault tolerance rate. |
