Abstract

The invention provides a cluster node fault recovery method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining node information of each cluster node in a cluster group, and the node information of each cluster node comprises the health state and data storage address of the cluster node; determining a fault cluster node in the cluster group, whereinthe fault cluster node is a cluster node of which the health state is an offline state; judging whether a data file directory and/or a data file exist/exists in the data storage address of the faultcluster node or not to obtain a judgment result; and restarting and/or reconstructing the fault cluster node according to the judgment result. Automatic recovery of the fault cluster node is realized.

Description

technical field [0001] The present application relates to the technical field of database clusters, and in particular to a fault recovery method, device, electronic equipment and storage medium for cluster nodes. Background technique [0002] With the development of cloud computing, the database platform has become a new standard in the industry, providing users with faster and more flexible resource usage methods, and improving resource delivery speed and elasticity. In short, database cluster technology is a combination of multiple databases. Each node database manages its own data. Data synchronization between databases is achieved through data replication technology, providing read-write or read-only services. By building database middleware or load balancing equipment at the front end of the database cluster, application requests are distributed to each node to achieve cluster load balancing and failover. [0003] In the existing technology, MySQL group replication tec...
