Cluster virtual machine high availability method and system

Abstract

The invention provides a cluster virtual machine high availability method and system. The method comprises the steps that a control node automatically triggers a calculation node at regular time for fault simulation operation, and the fault simulation operation comprises virtual machine distribution operation and resource simulation scheduling operation; the control node updates a high-availability event according to the fault simulation operation and issues the high-availability event to the corresponding computing node; high-availability triggering conditions are set according to network detection, shared storage detection, service state detection and proxy virtual machine detection; after the failed computing node reaches the high-availability triggering condition, a high-availability operation is executed, a high-availability execution result is reported and a high-availability state is updated. According to the method, the high-availability process of the Openstack cloud platformis optimized, and the high-availability execution reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of cloud platforms, and in particular relates to a high-availability method and system for a cluster virtual machine. Background technique [0002] In the large environment of data flow, continuous and stable access to data is a prerequisite for business operations. In the Openstack cloud platform, there are more and more implementation solutions for high availability of hosts. When a computing node hardware failure occurs, Through a series of judgment, scheduling, and execution processes, the virtual machine running on the computing node is restarted on other computing nodes to reduce the downtime of the virtual machine and business interruption, thereby achieving high availability of the host. [0003] A high-availability cluster is a group of computer systems that jointly provide network resources for clients. Each computer that provides services is called a node. When a node fails, the request will be tr...

Problems solved by technology

[0005] (1) The evacuate solution natively provided by Openstack is generally adopted, which needs to go through multiple module interactions, scheduling and execution, and the steps are complex, and it depends on the control layer of the cloud platform. When the control layer of the cloud platform is unstable, high-availability switching failure occurs The probability is very high. When a host high availability event occurs, multiple concurrent tasks may be executed, resulting in task execution failure;

[0006] (2) In the normal operating state, there is a lack of judgment and detection of high-availability conditions, and it is impossible to guarantee the high-availability execution results of the host when the host fails
