Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] At present, the data of the existing primary node is easily stolen by the disguised secondary node, so that the data security cannot be guaranteed. Based on this, the embodiment of the present invention provides a method, system, server, and computer-readable medium for preventing pseudo-nodes from joining. By setting a threshold, it can prevent pseudo-nodes from joining, prev...

Abstract

The invention provides a method, system, server and computer-readable medium for preventing false nodes from joining, relates to the field of communication technology, and is applied to a distributed replication block device DRBD node, where the primary node and the secondary node of the DRBD node are peer nodes. , the method includes: receiving the first threshold sent by the peer node; wherein, the peer node contains a threshold file storing the first threshold; comparing the first threshold with the second threshold of the peer node stored by itself; when comparing When the result meets the set condition, a connection is established with the peer node; when the comparison result does not meet the set condition, the connection is not established with the peer node. The present invention can prevent false nodes from joining by setting a threshold, prevent the data of the master node from being stolen, and improve data security.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system, server and computer-readable medium for preventing false nodes from joining. Background technique [0002] Distributed Replicated Block Device (DRBD) provides users with a real-time data synchronization technology. After the DRBD primary and secondary nodes establish a TCP connection, the primary node will mirror the data to the secondary node in real time, that is, the primary node (primary node) The data of the server) is synchronized to the secondary node (secondary server) in real time, so that the data of the primary and secondary nodes are consistent in real time. However, DRBD does not provide an effective mechanism to prevent pseudonodes from joining. [0003] At present, after the primary and secondary nodes of DRBD disconnect the TCP connection, they can join new nodes arbitrarily, that is, use a new secondary node to connect to the pri...
