The present invention first builds an Openstack cloud platform, sets the IPMI address, IPMI login username and password of the physical machine; then the Openstack cloud platform control node sends a request to shut down a virtual machine to the target physical machine through a component, waits for all virtual machines to be successfully shut down, and then sends a startup, shutdown or restart command to the baseboard management controller (BMC) of the target physical machine; finally, the baseboard management controller (BMC) of the physical machine executes the request and returns the execution result. The present invention solves the problems that the virtual machine needs to be shut down before the physical machine is shut down and the application service deployed therein is guaranteed to exit normally, that the Juno version of the Openstack open source cloud platform cannot be physically shut down remotely, and that the power status of the physical machine and the virtual machine cannot be uniformly managed; and can be applied to the power control of the physical machine of the cloud platform.

一种基于Openstack的物理机远程关机方法A remote shutdown method for physical machines based on Openstack

技术领域technical field

本发明涉及物理机电源控制技术领域，特别是一种基于Openstack的物理机远程关机方法。The invention relates to the technical field of physical machine power control, in particular to an Openstack-based remote shutdown method for a physical machine.

背景技术Background technique

随着Openstack开源云平台快速发展，已经有越来越多服务商和企业通过开源IasS(基础设施即服务)云平台搭建类似亚马逊公有云的服务，包括有新浪、中国移动、中国电信、国家电网、日本电信运营商KDDI等用户也使用上开源Openstack云平台。然而Openstack云平台侧重于对虚拟机进行远程管控，而忽略物理机远程管控重要性。随着业务的不断扩展导致云平台增加越来越多的物理机节点来提供虚拟化服务，随之而来的问题：With the rapid development of the Openstack open source cloud platform, more and more service providers and enterprises have built services similar to Amazon's public cloud through the open source IasS (Infrastructure as a Service) cloud platform, including Sina, China Mobile, China Telecom, and State Grid , Japanese telecom operator KDDI and other users also use the open source Openstack cloud platform. However, the Openstack cloud platform focuses on remote control of virtual machines, while ignoring the importance of remote control of physical machines. With the continuous expansion of business, the cloud platform adds more and more physical machine nodes to provide virtualization services, and the following problems arise:

一是传统开源云平台通常没有物理机远程管理的功能，不能通过云平台统一远程管理物理机，需要另外一套物理机管理系统来管理物理机，特别是服务器空闲不用，需要远程对物理机进行关机操作。One is that the traditional open source cloud platform usually does not have the function of remote management of physical machines. It cannot remotely manage physical machines through the cloud platform. Another set of physical machine management system is needed to manage physical machines. Especially when the server is idle, it is necessary to remotely manage physical machines. Shutdown operation.

二是应用服务质量问题。众所周知，用户的最关心的应用都部署在虚拟机里面，而虚拟机则基于物理机。若对物理机进行关机，为了保证应用能够数据完整性，就需要通过云平台先关闭该物理机上所有虚拟机，保证应用正常退出，才能通过其他系统进行物理机关机操作。The second is the problem of application service quality. As we all know, the most concerned applications of users are deployed in virtual machines, and virtual machines are based on physical machines. If the physical machine is shut down, in order to ensure the data integrity of the application, all virtual machines on the physical machine need to be shut down through the cloud platform to ensure that the application exits normally, and then the physical shutdown operation can be performed through other systems.

为了Openstack云平台统一管理物理机和虚拟机的电源状态，提高应用服务质量，需要一种基于Openstack的物理机远程关机的方法，统一管理虚拟机和物理机的电源状态。In order to uniformly manage the power status of physical machines and virtual machines on the Openstack cloud platform and improve application service quality, a method for remotely shutting down physical machines based on Openstack is needed to uniformly manage the power status of virtual machines and physical machines.

所述用户通过Openstack的Web界面，点击目标节点，并请求对目标节点远程关机。The user clicks on the target node through the web interface of Openstack, and requests to remotely shut down the target node.

通过Web服务器判断目标节点的电源状态符合关机的要求，若符合要求则下发请求给后台服务。The power state of the target node is judged by the Web server to meet the shutdown requirements, and if it meets the requirements, a request is sent to the background service.

所述目标节点收到请求后，通过Libvirt接口查询本地上所有处于正在运行状态的虚拟机列表，循环对每个虚拟机执行关闭电源操作，并返回结果。After the target node receives the request, it queries the list of all running virtual machines locally through the Libvirt interface, executes a power-off operation on each virtual machine in a loop, and returns the result.

所述后台服务收到虚拟机关闭电源的结果，IPMI的地址、登录用户名和密码，调用IPMI命令行工具的命令，通过IPMI智能平台管理接口发送给目标节点的BMC执行关机。The background service receives the result that the virtual machine is powered off, the IPMI address, login user name and password, calls the command of the IPMI command line tool, and sends it to the BMC of the target node through the IPMI intelligent platform management interface to perform shutdown.

所述Openstack是由NASA(美国国家航空航天局)和Rackspace合作研发并发起的，以Apache许可证授权的自由软件和开放源代码项目；是一个开源的云计算管理平台项目，由多个主要的组件组合起来完成具体工作Said Openstack is a free software and open source code project authorized by the Apache license, which was jointly developed and initiated by NASA (National Aeronautics and Space Administration) and Rackspace; it is an open source cloud computing management platform project, composed of several major Components combine to do specific work

所述Libvirt是Linux操作系统的免费、开源的主流虚拟化工具的C函数库，其目的是包括Kvm、Xen在内的各种虚拟化工具提供一套方便、可靠的编程接口，支持C、C++、Java和Python等多种主流编程语言。Described Libvirt is the C function storehouse of free, open-source mainstream virtualization tool of Linux operating system, and its purpose is that various virtualization tools including Kvm, Xen provide a set of convenient, reliable programming interface, support C, C++ , Java and Python and other mainstream programming languages.
