Redis cluster processing method and device, electronic equipment and computer readable storage medium

Abstract

The invention relates to the technical field of online transaction, in particular to a Redis cluster processing method and device, electronic equipment and a computer readable storage medium. According to the Redis cluster processing method, a Redis cluster comprises at least three Redis main nodes, each Redis main node is deployed on a host, and the Redis cluster processing method comprises the following steps: determining current state information of the Redis cluster; if it is determined that the current state information of the Redis cluster is that no less than half of the Redis main nodes in the at least three Redis main nodes are offline, obtaining hosts corresponding to the Redis main nodes which are not offline; configuring a Redis side standby node on the host corresponding to the Redis main node which is not offline, wherein the Redis side standby node is a replacement node corresponding to the Redis main node which is offline; and replacing the offline Redis main node withthe Redis side standby node to serve as the Redis main node, and determining the current state information of the new Redis cluster. According to the invention, the Redis side standby nodes are introduced, so that the Redis cluster function is recovered to be normal when the host corresponding to more than half of the Redis main nodes is in downtime.

Description

technical field [0001] The present application relates to the technical field of online transactions, and in particular to a Redis cluster processing method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In the prior art, for the Redis cluster, when multiple Redis master nodes go down at the same time, the master-slave nodes cannot be switched. Under the existing processing mechanism, this defect is hard to avoid. In order to avoid the above defects, the number of Redis master nodes is usually increased to reduce the probability that more than half of the Redis master nodes will be down at the same time; but this method will increase the number of devices and increase the maintenance cost of the product. Moreover, in the prior art, when managing a Redis cluster, it usually needs to be scheduled through a resource pool or a management center.

[0002] In the existing technology, for the Redis cluster, when multiple Redis master nodes go down at the same time, the master-slave nodes cannot be switched. Under the existing processing mechanism, this defect is hard to avoid

In order to avoid the above defects, the number of Redis master nodes is usually increased to reduce the probability that the number of Redis master nodes downtime exceeds half of the Redis master nodes at the same time; but this method will increase the number of devices and increase the maintenance cost of the product

Moreover, in the prior art, when managing a Redis cluster, it usually needs to be scheduled through a resource pool or a management center. In this way, due to the introduction of other devices or machines, additional resources are required, and trigger-type automatic generation cannot be achieved. , Start on demand, thus wasting system resources

Moreover, in the prior art, third-party functional module components are usually introduced to process the Redis cluster, resulting in increased maintenance costs
