Abstract

An embodiment of the invention discloses an ACL (access control list) authority control method and device. A user can set ACL authorities of a file and a directory by a Linux client, the set ACL authorities serve as extended attributes of the file and the directory and are stored in a metadata server, and the ACL authorities can include a read authority, a write authority, an execution authority,a deletion authority and a visual authority. A Windows client acquires the corresponding ACL authorities from the metadata server by calling a file system API (application program interface), and theACL authorities are verified and inherited. Based on the read authority, the write authority and the execution authority, the deletion authority and the visual authority are added. Compared with traditional ACL authority control, more advanced user access authority types are provided, diversified demands of enterprise users for data access authorities can be met, and users can control file readingand writing and authority granting capacity.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to an ACL permission control method and device. Background technique [0002] The main function of the access control list (Access Control List, ACL) can protect resource nodes on the one hand, prevent illegal users from accessing resource nodes, and limit the access rights of specific users on the other hand. In addition to the three types of permissions, more detailed local permission settings are provided, and operations such as reading, writing, deleting, and executing can be performed for a single user, a single directory or file, without the need to set permissions for the entire user group or other.
