Method and device for synchronizing account information in cluster system, and storage medium

Abstract

The embodiment of the invention discloses a method and device for synchronizing account information in a cluster system, and a computer readable storage medium. A broadcasting node generates a targetblock on a block chain of an own node acording to received command information, and stores corresponding account information into the target block, wherein the target block has corresponding identification information; the broadcasting node broadcasts account information and identification information to synchronization nodes of a cluster system, so that the synchronization nodes can update the block chains of the own node according to the account information and the identification information, and thus synchronization of the account information is achieved. The account information stored in each node of the cluster system is consistent, when the user identity is authenticated, each node can achieve the same function, so that the decentration treatment of the nodes is achieved, occurrenceof the situation that in a current NIS service, the cluster system is invalid due to crash of the management node or loss of the account information is avoided, and the robustness and security of cluster account information management are effectively enhanced.

Description

technical field [0001] The present invention relates to the technical field of cluster systems, in particular to a method, device and computer-readable storage medium for synchronizing account information in a cluster system. Background technique [0002] Computer clusters are widely used in the IT field. For example, in the field of high-performance computing / supercomputing, all supercomputers are linked by multiple nodes (servers) through the network, and various services deployed on them cooperate with each node to complete computing tasks. [0003] In a computer cluster, an integral part is the user login authentication system. Specifically, each node in the cluster system has its own operating system and user accounts under the system. For any user, the prerequisite for accessing (using) a node is that the node records the user account account information. [0004] For the Linux system, user login and authentication are realized through the user name and password in ...

AI Technical Summary

Problems solved by technology

Since the user management of the entire cluster relies on the user information recorded on the management node by the NIS service, if the information is hacked or maliciously tampered with, the control of the entire cluster will be lost, causing greater losses
