Cluster task balancing method and device based on single node triggering

The invention provides a cluster task balancing method based on single node triggering and a cluster task balancing device based on the single node triggering. The cluster task balancing method based on the single node triggering comprises the steps of regularly or periodically selecting available server nodes in a cluster; sending a triggering request to the available server nodes, wherein the triggering request carries the name of a to-be-handled task, so that the available server nodes are triggered to execute the to-be-handled task. By applying the method and the device, the task dispatch in the cluster can be realized based on single nodes; task loads can be dispersed relatively uniformly in the cluster, so that the cluster server resource can be utilized better.
