Background
The current hot backup scheme mainly includes the following modes:
(1) Master-slave mode: the slave node automatically synchronizes the data of the master node in the mode, and hot backup of the data is realized. When the master node fails, the designated slave node needs to be actively switched to be a new master node.
(2) Sentinel model: in the mode, a monitoring system is added in a master-slave mode, fault transfer is realized, sentinel nodes can monitor the running state of the master-slave node, and when a master node fails and is offline, the sentinel nodes can select one slave node to serve as a new master node to continue to provide services.
(3) Cluster mode: in the mode, a monitoring mechanism and a data fragmentation mechanism are added to a master-slave mode to realize failover and data horizontal expansion, a plurality of masters and slaves are combined in a cluster, each master node is responsible for storing a part of data in the cluster, and after a certain master node fails and is offline, the cluster can select one slave node of the node to serve as a new master node to continue to provide services.
