Problems solved by technology

Restarting the client means the service is unavailable, which is often intolerable for online businesses
[0005] (2) Time-consuming
When the client scale is thousands or even larger, it takes a very long time to restart the client
[0006] (3) High cost
The active-active solution means more resources are consumed and higher maintenance costs are required

Abstract

The embodiment of the invention provides a master-slave cluster switching method and device, and relates to the technical field of computers. According to the embodiment of the invention, the method comprises the steps: creating data nodes, and writing the configuration information of a master cluster into a node value of a corresponding data node; modifying the node value of the data node into the configuration information of a slave cluster to be switched during the switching of the master-slave clusters; monitoring whether the node value of the data node changes or not: obtaining the configuration information of the slave cluster to be switched when the node value is monitored to change, and modifying the link, pointing to the cluster, of a client according to the obtained configurationinformation, thereby achieving the switching of the master-slave clusters. According to the embodiment of the invention, the configuration information is written into the node value of the data node.When the client monitors that the node value of the data node changes, the configuration information of the slave cluster is obtained after the node value is monitored to change, and the link from the client to the cluster is modified, thereby achieving the online switching of the master-slave clusters.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for master-slave cluster switching. Background technique [0002] At present, more and more Internet companies have begun to use large-scale clusters to support their business. In order to ensure the high availability of clusters, many companies have adopted master-slave clusters for disaster recovery across computer rooms as a solution. At present, there are two main switching schemes for the master-slave cluster: scheme 1: modify the configuration and restart. The client prepares two sets of configurations, one set points to the master cluster, and the other set points to the slave cluster. When the master cluster fails, the client restarts the application and modifies the configuration to point to the slave cluster. Solution 2: active-active. Run two sets of clients at the same time, one client accesses the master cluster, and the other client accesses the slave ...
