Abstract

The invention discloses a method and device for selecting a master node in a distributed system, belonging to the field of Internet. The method comprises the following steps: a first distributed node receives a first data access request sent by a client, wherein the first data access request is a request for implementing data access through the master node of the distributed system, and the first distributed node is any of the distributed nodes in the distributed system; and when the first distributed node is not the master node of the distributed system, sending the first data access request to the master mode of the distributed system based on a stored master node identifier, when determining that the first data access request cannot be sent to the master node of the distributed system, determining that the master node of the distributed system has failure, and initiating a master node election request; and if the first distributed node is successfully elected, determining the first distributed node as the master node of the distributed system. According to the method and device disclosed by the invention, the communication bandwidths can be greatly saved, and the working efficiency of the distributed system can be increased.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for selecting a master node in a distributed system. Background technique [0002] With the rapid development of Internet technology, the application range of distributed systems is becoming wider and wider. Since the distributed system is a cluster system composed of multiple autonomous computer nodes as distributed nodes through a communication network, and the distributed system can serve as the server side to provide data for the client, the client can pass the distributed system Any one of the distributed nodes in the data access. In order to ensure that the data accessed by the client through any distributed node in the distributed system is consistent, the distributed nodes in the distributed system are generally divided into a master node and multiple slave nodes. Not only can the data stored by itself be modified, but also the data stored in the multiple...
