Abstract

The present invention relates to a leader server election method and device based on the Fast Paxos algorithm. The method includes: each server in the server cluster regularly inquires about the online status of other servers, and when any decision server determines that the leader server in the server cluster is down When all decision servers are down, all other decision servers determine whether the leader server is down; when all decision servers determine that the leader server is down, each decision server sends its own SID to other decision servers and records tickets; When the SID of the current record is compared with the SID of the current record, when the SID of other decision servers is smaller than the SID of the current record, one vote is added to the SID of the current record, and when it is greater than the SID of the current record, the SID of the current record is replaced by other The SID of the decision server inherits the previous votes and adds a new vote; when the number of votes recorded by the SID of a certain decision server is equal to the number of all online decision servers, it is elected as the 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 ...
