Embodiment 1

[0053] A method for adaptive switching of OpenStack computing nodes to control nodes, wherein the OpenStack includes a control node group and a computing node group, such as figure 1 , the method includes:

[0054] S1: Divide the computing node group into a switchable computing node group and a non-switchable computing node group, and elect a computing node to be switched from the switchable computing node group through an election algorithm;

[0055] S2: Trigger monitoring on a periodic basis. If a control node group is found to have a node failure or the total load is too high, live migrate the virtual machine on the computing node to be switched to other computing nodes in the group;

[0056] S3: Combine the container technology with the automatic management tool to switch the computing node to be switched to the control node and join the control node group described in step S2.

[0057] Before the hot migration of the virtual machine described in step S2, the computing re...

Embodiment 2

[0078] In this implementation, the calculation method of the total load of the control node group is calculated using a forecasting algorithm, and the others are the same as in Embodiment 1, and the forecasting algorithm is specifically:

[0079] Based on the historical monitoring data of the control node, a neural network linear regression model with multiple inputs and single outputs is used for prediction, and the neural network linear regression model is:

[0080] Z=WX+B

[0081] Where Z is the load forecast value of the control node, X={x 1 ,x 2 ,...,x N} is the input sample, which is the time or the number of tenants, W={w 1 ,w 2 ,...,w N} is the weight matrix, B={b 1} is the offset matrix, use the mean square error function as the cost function, calculate W and B through forward calculation and backward conduction, and obtain the total load of the control node group according to the obtained load prediction value Z, if the total load exceeds the preset threshold,...

Embodiment 3

[0083] An apparatus for adaptively switching an OpenStack computing node to a control node corresponding to Embodiment 1, the OpenStack includes a control node group and a computing node group, and the apparatus includes:

[0084] The monitoring agent module is used to send heartbeat packets to each control node in the control node group to determine whether a node failure occurs in the control node group; this module is also used to collect the load information of each control node in the control node group, and according to the collected load information to calculate the total load of the control node group, or predict the total load of the control node group based on historical load information, and judge whether the control node group is overloaded according to the set load threshold;

[0085] The node switching module is used to divide the computing node group into a switchable computing node group and a non-switchable computing node group. The computing node to be switche...

Abstract

The invention relates to a method and a device for adaptively switching an OpenStack computing node into a control node. The OpenStack comprises a plurality of groups of control node groups and computing node groups, and the method comprises the following steps: S1, dividing the plurality of groups of computing node groups into switchable computing node groups and non-switchable computing node groups, and electing from the switchable computing node groups through an election algorithm to generate computing nodes to-be switched; s2, periodically triggering monitoring at regular time, and if a node fault or an overhigh total load of a control node group is found, thermally migrating the virtual machine on the computing node to-be switched to other computing nodes of the computing node groupwhere the virtual machine is located; and S3, switching the computing nodes to-be switched into the control nodes through an automatic management tool in combination with a container technology, and adding the control nodes into the control node group in the step S2. Compared with the prior art, the method has the advantages of high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of OpenStack cloud platform, in particular to a method and a device for adaptively switching an OpenStack computing node to a control node. Background technique [0002] OpenStack is an open source cloud computing management platform, which can realize the management of a large number of computing resources, storage and network resources, and provide a unified control panel for management.
