All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a cloud host service management method according to an embodiment of the present application, and referring to fig. 1, the method includes:
s101: installing a qemu-guest-agent tool inside the cloud host;
s102: sending a business operation command to the cloud host through a libvirt daemon process so that the cloud host executes business operation corresponding to the business operation command;
specifically, the execution subject of the application is a cloud computing platform, which is called a cloud platform for short. That is to say, the service inside the cloud host is operated and the service information of the cloud host is displayed through the cloud platform. Cloud host refers to a virtual host. In order to realize communication between a cloud platform and a cloud host, a libvirt daemon process is started on the host, and a qemu-guest-agent tool is installed inside the cloud host, so that the libvirt daemon process is communicated with the cloud host.
For the related contents of libvirt daemon and qemu-guest-agent tools, the details are not repeated herein, and refer to the prior art.
On the basis of a communication mechanism realized based on a libvirt daemon process and a qemu-guest-agent tool, a service operation command is issued by a cloud platform and is sent to the qemu-guest-agent tool of a cloud host through the libvirt daemon process, so that the cloud host executes corresponding service operation after receiving the service operation command. The service operation command may be an install service command, a run service command, an unload service command, a pause service command, and the like.
S103: receiving business information sent by the cloud host through the qemu-guest-agent tool, and displaying the business information;
specifically, the cloud platform receives the service information fed back by the cloud host and further displays the service information, besides issuing the service operation command to the cloud host. The service information may include service running state, information that the service occupies the CPU and the memory, service alarm information, and the like.
In a specific implementation manner, the receiving of the service information sent by the cloud host through the qemu-guest-agent tool includes: and receiving the service information which is regularly collected and regularly sent by the cloud host through the qemu-guest-agent tool.
Specifically, a business detection module realized based on a shell script in the cloud host regularly counts the information such as the running state, the CPU occupancy rate and the memory occupancy rate of the business in the cloud host, and records the information such as the running state, the CPU occupancy rate and the memory occupancy rate in a specified file for storage. Furthermore, a business information reporting module realized based on a qemu-guest-agent tool in the cloud host reports information such as the running state, the CPU occupancy rate and the memory occupancy rate of the cloud host at regular time.
In addition, in a specific embodiment, the displaying the service information includes: and displaying the service information on the OpenStack cloud platform.
Specifically, in this embodiment, the cloud platform is built based on an OpenStack framework, and after receiving the service information reported by the cloud host, a cloud host service display module of the OpenStack cloud platform displays the service information reported by the cloud host, so that an operator can check the service information of the cloud host and perform corresponding operations according to information such as the operating state, the CPU occupancy rate, and the memory occupancy rate of the cloud host.
S104: when a cloud host service automatic processing mechanism is started, the service information is analyzed, and when the consumption of the service on the cloud host resources reaches a preset threshold value, a service pause command is sent to the cloud host through the libvirt daemon process so as to pause a target service.
Specifically, a cloud host service automatic processing mechanism is introduced into the cloud platform, when the cloud host service automatic processing mechanism is started, the cloud platform further analyzes the service information after receiving the service information reported by the cloud host, judges whether the service consumption of a CPU and a memory of the cloud host is too large, and sends a service suspension command to the cloud host when the service consumption of the CPU and the memory of the cloud host is too large, namely when the service consumption of the cloud host resource reaches a preset threshold value, so as to suspend a target service and reduce the consumption of the service on the CPU and the memory.
In a specific embodiment, sending a service suspension command to the cloud host through the libvirt daemon to suspend a target service includes: respectively calculating the sum of the CPU occupancy rate and the memory occupancy rate of each service; comparing the priority of each service; if the priorities of the services are different, suspending the service with the lowest priority; if the priority of each service is the same, comparing the sum of the CPU occupancy rate and the memory occupancy rate of each service, and suspending the service with the maximum sum of the CPU occupancy rate and the memory occupancy rate.
Specifically, each service is prioritized according to the importance level of each service within the cloud host. When the target service, namely the service to be suspended, is determined, the sum of the CPU occupancy rate and the memory occupancy rate of each service is respectively calculated, and the sum of the CPU occupancy rate and the memory occupancy rate is used as a weight ratio. Firstly, comparing the priority of each service; if the priorities of the services are different, suspending the service with the lowest priority; and if the priorities of the services are the same, comparing the weight ratios of the services, and suspending the service with the largest weight ratio.
That is, when a certain service or certain services in the cloud host are suspended, the service with high priority is preferentially ensured to run, and for the service with the same priority, the service with high CPU and memory occupancy rate is preferentially suspended.
For example, the priority of service 1, service 2, and service 3 is high priority, medium priority, and low priority in this order, and at this time, service 3 is suspended preferentially when the service is suspended.
For another example, if the priorities of the service 1, the service 2, and the service 3 are the same and are all of medium priority, and the sum of the CPU occupancy and the memory occupancy of the service 1 is 30%, at this time, the sum of the CPU occupancy and the memory occupancy of the service 2 is 35%, and the sum of the CPU occupancy and the memory occupancy of the service 3 is 25%, the service 2 is preferentially suspended when the service is suspended for the service 1, the service 2, and the service 3 having the same priority.
After the consumption of the service on the cloud host resources is reduced to be below the preset threshold, the cloud platform can further issue a service operation command to the cloud host to resume the suspended service to operate again.
Further, on the basis of the above embodiment, as a specific implementation manner, the method further includes: and after receiving a closing instruction, closing the automatic cloud host service processing mechanism.
Specifically, an operator can manually issue a closing instruction, the cloud platform closes the cloud host service automatic processing mechanism after receiving the closing instruction, and the subsequent cloud platform does not automatically analyze and judge the service signal of the cloud host.
In summary, the cloud host service management method provided by the present application includes: installing a qemu-guest-agent tool inside the cloud host; sending a business operation command to the cloud host through a libvirt daemon process so that the cloud host executes business operation corresponding to the business operation command; receiving business information sent by the cloud host through the qemu-guest-agent tool, and displaying the business information; when a cloud host service automatic processing mechanism is started, analyzing the service information, and when the consumption of the service on the cloud host resources reaches a preset threshold value, sending a service pause command to the cloud host through the libvirt daemon process so as to pause a target service.
