Abstract

The invention relates to a leader server election method and device based on a Fast Paxos algorithm. The method comprises the steps that each server in a server cluster regularly inquires the online condition of other servers, and when any decision server determines that a leader server in the server cluster is down, all other decision servers determine whether the leader server is down or not; when all the decision servers determine that the leader server is down, each decision server sends own SID to other decision servers and record votes; when the SID of other decision servers is received, the SID is compared with a currently recorded SID, when the SID of other decision servers is smaller than the currently recorded SID, a vote is added to the currently recorded SID, and when the SID of other decision servers is larger than the currently recorded SID, the currently recorded SID is replaced with the SID of other decision servers, previous votes are inherited, and a new vote is added; and when the number of SID votes recorded by a certain decision server is equal to the number of all the online decision servers, the decision server is elected as a new leader server.

Description

technical field [0001] The present disclosure relates to the technical field of server management, in particular to a method and device for selecting a leader server based on the Fast Paxos algorithm. Background technique [0002] In the computer field, distributed systems have become the most effective solution for computer expansion and matching different computer performance. Whether in the game industry or in other large-scale server systems, computer programs without distributed system thinking have almost no scalability and performance. However, with the distributed system, one of the problems that comes with it is the consensus problem. To solve this problem, an efficient consensus algorithm is needed. [0003] The consensus algorithm describes the process in which multiple nodes in a distributed system reach a consensus on a certain state. Consensus algorithms allow a group of machines to share state information as a whole and reach consensus even if some of them ...
