Problems solved by technology

[0004] The existing technology has realized the HA function of openstack computing nodes, but does not provide a high-availability test method for computing nodes based on openstack. The test of various modes of HA is manually tested by testers to observe the status of computing nodes. The evacuation of cloud hosts, cloud The relationship between the number of hosts and the capacity of the computing nodes occupied is not clear, and the test of each mode of HA is not sufficient, and the convenience is poor

Abstract

The present invention provides a high-availability testing method for openstack computing nodes, comprising the following steps: S1. deploying a cluster based on an openstack management platform; S2. setting the cluster as a high-availability cluster, obtaining a recovery method of the high-availability cluster selected by a user, and performing a high-availability cluster according to The recovery method of the high-availability cluster is to add a host and configure the state of the host; the recovery method includes automatic, reservation, and reservation priority; S3. Simulate the failure of the computing node corresponding to the cloud host in the high-availability cluster, according to the recovery method of the high-availability cluster , predict the evacuation result of the cloud host, and verify whether the predicted evacuation result of the cloud host is consistent with the actual evacuation result of the cloud host. The invention automatically realizes the effective verification of the high-availability function of the computing nodes of the openstack, conducts a comprehensive test according to the evacuation situation of the cloud hosts, the number of the cloud hosts and the occupied computing node capacity correlation, the testing is sufficient, and the convenience is good.

Description

technical field [0001] The invention belongs to the technical field of cloud product testing, in particular to an openstack computing node high availability testing method. Background technique [0002] HA, short for High Availability, high availability. [0003] Openstack is an infrastructure and service (IaaS) cloud computing platform. It provides basic services such as computing, network, and storage by pooling resources in the entire data center, and these basic services can be allocated through the openstack operation interface Horizon. and create. Cloud hosts are built on computing nodes. When a computing node fails, it is especially important that the cloud host can continue to work without being affected. In order to ensure the normal operation of the cloud host, it is particularly important to perform efficient and accurate HA testing of computing nodes. [0004] The existing technology has implemented the HA function of openstack computing nodes, but does not pro...
