Embodiment Construction

[0104] See Figure 1-Figure 6 , LXPFS cluster distributed file storage system, the present invention is characterized in that, adopt LXPFS cluster to provide access method for application, access the file in LXPFS through the packaged JS API; The mode of accessing LXPFS file is divided into three kinds: read, write and delete ;The component for accessing LXPFS files is realized on the front end. In web application development, only one component needs to be generated, and the corresponding interface can be called to realize the access; the system adopts the master-slave mode architecture, which consists of one Dispatchnode and one or more Tasknodes ;Dispatchnode is a controller server, which is responsible for allocating the storage of all files and processing and forwarding client requests. Tasknode is set up on each node, responsible for managing the storage on the node where it is located and responding to client requests; uploading files is to write data into In the Taskno...

Abstract

The invention discloses an LXPFS (Linux XProgram File System) cluster distributed file storage system. An access method is provided for an application by employing an LXPFS cluster. Files in the LXPFS are accessed by a packaged JS API. The mode of accessing the files in the LXPFS comprises three kinds: read, write and deletion. A module for accessing the file of the LXPFS is realized at a front end, only one module is generated in a Web application development process, and access can be realized by calling a corresponding interface. According to the system, a controller/worker mode framework is employed. The system is composed of a dispatch node and more than one task nodes. The dispatch node is a controller server and is responsible for dispatching storage and processing of all files and forwarding a request of a client. The task nodes are responsible for managing storage on the nodes and responding to the request of the client. Uploading files indicates writing data in the task nodes. Downloading the files indicates reading file data of the task nodes. According to the system, uploading is carried out in a mode of segmenting the big files; the sizes of the uploaded files are not limited; the problems of high-capacity storage, distributed storage and load balance are solved; and the function of a file management module is provided for a Web server in a service mode.

Description

technical field [0001] The invention is used to solve the file access and file storage of Web service items, and specifically relates to the technical field of LXPFS cluster distributed file storage system. Background technique [0002] The application system based on Web technology, because of its short development cycle, has nothing to do with the user platform, is easy to implement interactive applications, and can collect, process and release information quickly and efficiently, has developed rapidly in recent years. [0003] Data is very important for applications. It can be said that almost all application system development revolves around data, and Web application systems are no exception. During the user's use, the application system provides data when the user needs it. When the web system interacts with users, it is actually a data exchange process. The data of the application system is mainly stored in the database and files, but the database is also based on f...
