Abstract

The present invention provides a method and device for managing active and standby nodes in a communication system and a high-availability cluster; the method includes: the standby node detects whether the active node is working normally; after detecting that the active node is not working normally, The standby node triggers the execution of the master-standby switching operation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for managing active and standby nodes in a communication system and a high-availability cluster. Background technique [0002] In a large-scale commercial software system, in order to ensure the stability of operation, it is usually required that the entire service cannot be interrupted due to the failure of one server, that is, a single point of failure should be avoided. Typically, a cluster is usually composed of two active and standby servers. Under normal circumstances, the active server provides external services. When the active server fails, the secondary server takes over and continues to provide external services. The fault detection and takeover process between the active and standby servers is a technical difficulty. The current typical method requires third-party arbitration, that is, the active and standby servers report their status to the arbitrator ...
