Problems solved by technology

[0002] With the rapid development of science and technology, it is particularly important to ensure the stability of the application system. At this stage, many softwares have their own high-availability programs to ensure the high availability of the application cluster. However, many applications are subjective in judging the status of the cluster. , the status of the cluster nodes cannot be effectively fed back, and when there are many clusters, the number of highly available programs deployed will increase accordingly. Each deployed application is separately deployed for high availability, which is too inefficient and reusable

Embodiment 1

[0046] This embodiment proposes a cluster disaster recovery management system based on ETCD. The system is based on the distributed storage characteristics of ETCD. Through multi-node monitoring, the system votes on the status of the nodes in the cluster. According to the voting results, it is confirmed whether the nodes in the cluster are abnormal. And switch the nodes in the abnormal state to complete the real-time monitoring of the status of the nodes in the cluster. At the same time, by recording the status of the nodes, the stability of each node in the cluster is guaranteed.

[0047] During the implementation of this embodiment, the cluster disaster recovery management system monitors clusters of the same type through the same set of monitoring programs, and monitors clusters of different types through different monitoring programs.

[0048] combined with figure 1 , in this embodiment, for the implementation process of the system, the cluster disaster recovery management...

example ID

[0061] First, the user sends a request to delete the cluster monitoring to the control service module 2 through the API interface module 1, and the request parameter should be the monitoring instance ID when creating the cluster monitoring;

[0062] Subsequently, according to the request of the user to delete cluster monitoring, delete the metadata information that is stored in the ETCD distributed storage module 4 through the event monitoring module 3 and is identical to the monitoring instance ID;

[0063] At the same time, the user deletes the cluster monitor with the same monitoring instance ID in the control service module 2 .

[0064] In this embodiment, the involved user request also includes updating the cluster monitoring. When the user updates the cluster monitoring, the update operation includes:

[0065] First, the user sends a request to update the cluster monitoring to the control service module 2 through the API interface module 1, and the request parameter shou...

Abstract

The invention discloses a cluster disaster recovery management system based on an ETCD. Relating to the technical field of cluster management, the system is based on ETCD distributed storage characteristics. The node state in the cluster is voted through a multi-node monitoring mode, whether the node in the cluster is abnormal or not is determined according to the voting result, the node in the abnormal state is switched, real-time monitoring of the node state in the cluster is completed, and meanwhile, the stability of each node in the cluster is ensured by recording the node state. Accordingto the method, the stability of each node in the cluster can be ensured, meanwhile, multi-cluster monitoring is supported, the same set of monitoring programs can be used by the clusters of the sametype, and different monitoring programs are used by the clusters of different types, so that the reusability of the monitoring programs is improved, the deployment efficiency of the clusters is also improved, and the stability of the clusters is ensured.

Description

technical field [0001] The invention relates to the technical field of cluster management, in particular to an ETCD-based cluster disaster recovery management system. Background technique [0002] With the rapid development of science and technology, it is particularly important to ensure the stability of the application system. At this stage, many softwares have their own high-availability programs to ensure the high availability of the application cluster. However, many applications are subjective in judging the status of the cluster. , the status of the cluster nodes cannot be effectively fed back, and when there are many clusters, the number of high-availability programs deployed will increase accordingly. Each deployed application is separately deployed for high availability, which is too inefficient and has low reusability. [0003] Etcd is a distributed key-value storage developed by CoreOS based on Raft, which can be used for service discovery, shared configuration, ...
