Embodiment Construction

[0031] The present invention proposes a cluster management protocol with a master-slave structure, which abandons the token ring structure in the existing cluster management protocol, divides the member nodes in the cluster into master nodes and slave nodes, and the master node and slave nodes pass through Send handshake messages to each other to complete the synchronization of node information of other member nodes in the cluster, making the synchronization of node information more efficient.

[0032] In the cluster applying this protocol, when a node joins and exits, after simple and efficient interaction between the master node and the slave node, the node information synchronization and node information update of other nodes can be quickly completed, and the joining and Exit or the failure of a single node will not cause the nodes in the entire cluster to re-synchronize node information. Therefore, the stability of the cluster applying this protocol will be higher, and when...

Abstract

The invention provides a node management method. The method includes that a slave node periodically sends a first handshake message to a main node, and the first handshake message includes node information of the slave node; the main node maintains a first node information list according to receiving conditions of the first handshake message that is periodically sent by the slave node, and the first node information list includes node information of the slave node that is already stored in the main node and node information of the main node; the main node periodically sends a second handshake message to the slave node that is included in the first node information list; the second handshake message includes the first node information list that is maintained by the main node according to the receiving conditions of the first handshake message; the slave node performs synchronization on a second node information list that is locally stored according to the first node information list. By means of the node management method and device, synchronization of node information in a cluster is further efficient.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a node management method and device. Background technique [0002] In the cloud computing management platform, a cluster (cluster) manages a group of server hosts or virtual machine resources, and each server is a node (node) in the cluster. Administrators can add and delete nodes from the cluster by operating the cluster; Clusters allow administrators to manage multiple hosts and virtual machines as easily as a single entity, reducing management complexity. At the same time, by regularly monitoring the status of hosts and virtual machines in the cluster, the business continuity of the data center is ensured. For example, when a server host fails, all virtual machines running on this host can be restarted on other hosts in the cluster. [0003] The cluster can also automatically perceive the joining or exiting of nodes through the cluster management protocol, so a...
