Problems solved by technology

[0003] However, in this process, there are two problems: 1. When a node fails, the intervention of technical personnel is required to complete the recovery of the failed node, and the automatic failure recovery mechanism cannot be implemented; 2. The failure recovery introduces hum

Example Embodiment

[0041] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0042] In the system of fast and automatic failure recovery of active and standby nodes, there are three levels. The first level is a cluster of physical machines, the second level is a cluster of virtual machines in a single physical machine, and the third level is the virtual machine itself. There are two aspects to achieve fast failure recovery, namely, a single virtual machine failure recovery and a physical machine (including several virtual machines) failure recovery.

[0043] This application uses virtualization technology to manage physical machines, and multiple virtual machines are run on one physical machine, and each virtual machine corresponds to a previous master node or a backup node. Application services are ru...

Abstract

The invention relates to a method and system for carrying out automatic master and slave failure recovery on the basis of virtualization. Deployment includes a control center and a cluster system of a plurality of physical machines, and a plurality of virtual machines operate on each physical machine; the operating states of all the physical machines are monitored by the control center in real time, and the operating states of the virtual machines in each physical machine are monitored by the physical machine in real time; when failure occurs, whether a virtual machine or a physical machine fails is judged, and specific automatic failure recovery is then carried out. The invention introduces the virtualization technology into the failure recovery of master and slave systems, failure sensing and failure recovery can be automatically carried out without human intervention, and compared with the conventional manual recovery method, the invention can realize rapid failure recovery and control recovery time at the minute level, thus shortening the time of instability of service offered by only one machine; and moreover, the invention can realize the rapid failure recovery of both the virtual machines and the physical machines, thus expanding the coverage of reliability assurance.

Description

technical field [0001] The invention relates to the field of virtualization technology, in particular to a method and system for automatically recovering faults of active and standby nodes based on virtualization technology. Background technique [0002] With the development of the Internet and the high-quality requirements of production systems for services, providing 7×24 hours of uninterrupted operation has become the goal of service providers. At present, in order to ensure high-quality services, services are usually provided in active / standby mode. In the normal service provision process, it is the master node that responds to the client's request for service. When the master node fails, the slave node senses it in real time, then takes over the service and becomes the master node. After the failure of the primary node, the technical personnel will solve the failure, and then let the node restart to provide services and become the standby node. Therefore, after recov...
