Embodiment Construction

[0041] The embodiment of the present application provides a host upgrade method and device, which can solve the problem of low efficiency of the server upgrade solution in the prior art. Wherein, the method and the device described in this application are based on the same inventive concept, and since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0042] Such as figure 1 As shown, according to the deployment of the cloud operating system, one or more virtual machines (virtual machine, VM) will be deployed on each host; in order to distinguish each host, the hosts are numbered, respectively host 1, host 2, ... Host N-1, host N, one or more virtual machines are deployed on each host, for the convenience of explanation, take two virtual machines deployed on each host as an example; before the upgrade, an empty virtual machine will be config...

Abstract

A method and device for upgrading a host. Firstly, at least one target host is selected from multiple hosts, and at least one target host needs to meet certain conditions; after at least one target host is determined, stop deploying in one or more target business groups The services run by all virtual machines of at least one target host maintain the services run by virtual machines not deployed on at least one target host in one or more target service groups; and then at least one target host is upgraded. Using the above method, selectively select at least one target host from multiple hosts to upgrade, so that multiple hosts can be upgraded in multiple batches. Under the premise of ensuring that the business of each business group is not interrupted, At least one target host can be upgraded in parallel.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for upgrading a host. Background technique [0002] In the cloud service in the telecommunications scene, the corresponding business is mainly deployed through three layers, from top to bottom are software service (software as a service, SaaS) layer, platform service (platform as a service, PaaS) layer, infrastructure service (infrastructure as a service, IaaS) layer. The business-related software environment and software logic are deployed in the SaaS layer. The PaaS layer can provide a software deployment platform, eliminating details such as hardware and operating systems, so that the PaaS layer can achieve seamless expansion. IaaS is the bottom layer of cloud services, which mainly provides some basic resources, such as cloud operating system (for virtual machine deployment), servers, storage, switches and other hardware. Deployed o...
