Cluster resource distribution method and device

The invention provides a cluster resource distribution method and device. The device comprises a resource configuration module, wherein the resource configuration module furthermore comprises a resource detection sub-module and a user resource configuration upper limit adjustment sub-module; the resource detection sub-module is used for detecting whether the current cluster resource using state is idle or short; and the user resource configuration upper limit adjustment sub-module is used for improving the upper limit of user resource configuration when the cluster resource detection module detects that the current cluster resource is idle, and reducing the upper limit of the user resource configuration when the cluster resource detection module detects that the current cluster resource is short. Through the method and device provided by the invention, the flexible dynamic adjustment for system resources in multi-tenant distributed management systems is realized, so that the resources are fully utilized, the
