Method and system for electing master node in cluster, and medium

Abstract

Disclosed in the present application a method for electing a master node in a cluster. The method comprises the following steps: on the basis of a hyper-converged cloud platform, creating a storage cluster, and configuring a status detection program and a full response operation function; performing active node screening on the storage cluster, so as to obtain an active node set and a candidate node set; setting a first data situation, detecting a second data situation of the active node set, and executing a determination step on the basis of the first data situation and the second data situation, so as to obtain a determination result; when the determination result is a first result, setting an arrangement sequence and a first selection position, and electing a first master node according to the arrangement sequence, the first selection position and the active node set; and when the determination result is a second result, configuring a consistency election algorithm and a distributed election algorithm, and electing a second master node on the basis of the candidate node set, the consistency election algorithm and the distributed election algorithm. By means of the present application, an excessively long election time of a master node and unsuccessful election of the master node are avoided, thereby improving the deployment efficiency of a cluster.
