Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] figure 1 The structural block diagram of the master node used for the high-availability cluster system provided by the embodiment of the present invention divides the master node into three layers, one layer is used for information interaction, one layer is used for the allocation and management of cluster resources, and one layer is used for The startup and deactivation of cluster resources simplifies the working mechanism of the master node, making it...

Abstract

An embodiment of the present invention provides a high-availability cluster system and its master node and slave node. The master node includes a master resource allocation layer, a master information layer, and a master resource proxy layer, and the slave node includes a slave resource allocation layer, a slave information layer, and a slave resource proxy layer. Divide the master node and the slave node into three layers, one layer is used for information exchange, one layer is used for the allocation and management of cluster resources, and one layer is used for the start and stop of cluster resources, simplifying the master node and slave node The working mechanism is more convenient for the management and understanding of the master node and the slave node to learn the working principle. Whether it is the master node or the slave node, when it fails, you can quickly know where it is based on the failure performance after the failure. If a fault occurs on one layer, then only the fault inspection is performed on this layer, which narrows the scope of fault investigation and facilitates 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...
