Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 A schematic structural diagram of a distributed computing system provided by an embodiment of the present invention is shown. The distributed computing system includes: a management terminal 120 and a physical node 140 .

[0037] The management terminal 120 is a device such as a laptop computer, a desktop computer, a mobile phone, a tablet computer or the like. The management terminal 120 is used to manage the running conditions of each physical node 140 . Schematically, when the physical nodes 140 need to upgrade the operating system, the management terminal 120 controls each physical node 140 to upgrade.

[0038] The management terminal 120 is connected to the physical node 140 through the network 160 . The networ...

Abstract

The invention discloses a physical node upgrading method and a device. The method comprises the steps of determining the ithphysical node among the physical nodes not upgraded; upgrading the ithbatch of physical node; after upgrading completion, detecting the non-upgraded physical node existence; if non-upgraded physical nodes still exist, make i=i+1, and re-implement the steps of determining the ithbatch of physical node from the non-upgraded physical nodes, which solves the problem of the whole distributed system failing to provide external service under current technology when all physical hosts restart upgrading simultaneously, and long service interrupt duration when the upgrading duration is relatively long; and the physical node upgrading method and device achieves the effect of no service interrupt and that other physical nodes can still provide external service except the current batch when each batch of physical node is upgrading, and for upgrading the multiple physical nodes according to different batches.

Description

technical field [0001] The embodiments of the present invention relate to the field of computers, and in particular to a method and device for upgrading a physical node. Background technique [0002] OpenStack distributed computing system is an open source cloud computing management platform project. The OpenStack distributed computing system includes multiple physical hosts, and each physical host runs several service instances. Two instances of the same service can be deployed on different physical hosts in an active / standby manner, or multiple instances can be deployed in a load balancing manner. [0003] When the operating system is upgraded due to version updates, security vulnerabilities, driver updates, etc., the physical host needs to be restarted and upgraded. During the restart and upgrade process of the physical host, the virtual machines on the physical host will not be able to provide external services. A commonly used upgrade method in the prior art is: rest...
