Failure detection method and device for nodes in cluster system

Abstract

The embodiment of the invention provides a failure detection method and device for nodes in a cluster system. The method comprises the following steps that: a first node judges whether a first heartbeat message sent by a second node is received in preset time or not, wherein the first node is a neighbor node of the second node, and the first heartbeat message is a heartbeat message which is sent to each neighbor node of the second node in parallel by the second node; under the condition that the first node does not receive the heartbeat message sent by the second node, the first node sends a request message to other neighbor nodes other than the first node in all the neighbor nodes of the second node; the first node receives response messages carrying reception states sent by the other neighbor nodes; and under the condition that the first node determines that other neighbor nodes do not receive the heartbeat message according to the reception states, the first node determines that the second node fails. Through adoption of the failure detection method and device for the nodes in the cluster system, the node failure detection efficiency can be increased.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for detecting node faults in a cluster system. Background technique [0002] In a distributed cluster system, it usually includes a central node and multiple ordinary nodes. When the central node or ordinary nodes fail, it will have a great impact on the reliability of the distributed cluster system. Therefore, how to effectively implement node fault detection is very important. [0003] figure 1 is a schematic diagram of a node fault detection method in the prior art, such as figure 1 As shown, the ordinary nodes (B, C, D, E) send heartbeat messages to the central node (M) according to the heartbeat period, and the central node (M) detects the common Whether the node is faulty, wherein, one detection cycle can include multiple heartbeat cycles. At the same time, the central node (M) can also periodically send heartbeat messages to or...
