Abstract

The embodiment of the invention provides a high-availability cluster system, a master node and a slave node. The master node comprises a master resource allocation layer, a master information layer and a master resource agent layer; and the slave node comprises a slave resource allocation layer, a slave information layer and a slave resource agent layer. The master node and the slave node are respectively divided into three layers; one layer is used for information interaction, one layer is used for allocation management of cluster resources, and one layer is used for start and stop of the cluster resources. As the working mechanism of the master node and the slave node is simplified, more convenience is brought to the management of the master node and the slave node as well as the understanding and learning of the working principle therein. No matter the master node or the slave node is in failure, a person can know which layer of the node is in failure rapidly based on failure performances of the node and can further perform failure checking just for the layer, so that the failure checking range is shortened, and convenience is brought to fault inquiry.

Description

technical field [0001] The invention relates to the field of cluster technology, in particular to a high-availability cluster system and its master node and slave node. Background technique [0002] With the wide application and in-depth development of enterprise information systems, the number of core applications of users is increasing. Under the framework of this distributed multi-application system, high-availability cluster systems are increasingly accepted and widely used by users. In the high-availability cluster requirements, it is necessary for the nodes to transmit information to each other, and the nodes will count the resource utilization of each node, and allocate different cluster resources to each node. After each node knows the resource allocation result, it will start or stop related For cluster resources, the working mechanism of each node is complicated, and it is not easy to manage and understand the working principle. When a node fails, it is not conveni...
