However, in the face of a distributed file system with a large number of files, the permission control of a large part of the distributed file system can only achieve partition control of user files
In addition, although a small part can control the files, in the face of massive files, in order to perform permission information operations on each file, a distributed database has to be introduced to store permission information
Under the condition that the current distributed database technology is immature, it will undoubtedly increase the complexity of the system and the probability of errors

The invention relates to the technical field of distributed storage, and provides an authority management method for a distributed file system, which mainly comprises the following steps: storing uploaded file information uploaded by a user in a metadata server corresponding to the user, and calculating the metadata server by using a consistent hash algorithm according to a user ID; and generating file information according to the uploaded file information and the file creation request, and storing the file information in the metadata server, the file information including permission information of the uploaded file. According to user IDs, authority file fragments corresponding to the user IDs are distributed in the metadata servers through a consistent hash algorithm, and when a user modifies authority information of files stored in storage nodes, the metadata servers corresponding to the user can be obtained through direct calculation of the user IDs of the user, therefore, the complexity of the system and the error probability are reduced.
Description
Technical field[0001]The present invention relates to the technical field of distributed file systems, and more particularly to a permission management method, system, and storage medium of a distributed file system.Background technique[0002]Distributed file systems refer to data on a server, but disperse to multiple servers. Distributed facilitates tasks to allocate and optimize across the computer system, overcoming that traditional centralized file systems can lead to defects in server resource tight and response speed. By combining a large number of data storage server clusters, the internal representation of multiple storage servers / storage nodes work together, and the data storage task is divided into multiple sub-tasks in parallel storage, thereby reducing data storage time And increase data security.[0003]However, facing the distributed file system with massive files, a large part of the distributed file system permission control can only be partitioned to the user file.
