So as to achieve the purpose of recycling the computing resources. In the embodiment of the invention, the host is a server capable of bearing a virtualization operating system, the cloud server is a process on the host virtualized based on virtualization capability, and the virtualization capability is not limited to virtualization technologies such as qemu/kvm, xen and vmware.
Referring to fig. 1 and fig. 2, an application scenario of the method and the apparatus for releasing resources of a cloud server and the method and the apparatus for recovering the cloud server provided in the embodiment of the present invention is described first. In practical application, the device for realizing resource release of the cloud server and the device for realizing recovery of the cloud server provided in the embodiment of the present invention may be integrated into a server, and the server may interact with a plurality of hosts.
Referring to fig. 3, an embodiment of a method for releasing resources of a cloud server provided in the embodiment of the present invention is shown, and the embodiment of the present invention will be described in terms of a device for releasing resources of a cloud server, where the device for releasing resources of a cloud server may be specifically integrated into a server, and the embodiment may include the following steps:
step 301: and responding to the request for closing the cloud server, and ending the process of the cloud server.
The embodiment of the invention can be applied to the following scenes at least: (1) When the cloud server expires, the host automatically generates a request for closing the cloud server, and at the moment, a method for starting to execute resource release of the cloud server is triggered; (2) The user actively selects to temporarily close the cloud server, the host generates a request for closing the cloud server in response to the closing selection of the user, and at the moment, the method for releasing the resources of the cloud server is started. After receiving the request for closing the cloud server, the server may send an instruction to the host where the cloud server is located to end the process of the cloud server. In this embodiment, the host where the cloud server is located may be referred to as a first host.
Step 302: and releasing the computing resources used by the cloud server in the first host, and triggering the first host to delete the configuration file of the cloud server, wherein the configuration file comprises the computing resource value corresponding to the cloud server.
Each cloud server has a unique identifier, in practical application, a configuration table may be maintained, a first host corresponding to the cloud server is recorded, and the computing resources used by the cloud server in the first host may include a CPU, a memory, and the like. After the process of the cloud server is finished, the cloud server is destroyed and cleared from the first host machine, namely the computing resources used by the cloud server in the first host machine are empty, the first host machine is triggered to delete the configuration file of the cloud server, the cloud server is in an empty state on the first host machine, and the first host machine cannot obtain any information of the cloud server, so that the host machine can allocate the computing resources such as a CPU (central processing unit), a memory and the like used before the cloud server to other cloud servers for use.
Step 303: and updating the available computing resource value of the first host according to the computing resource value corresponding to the cloud server.
After the computing resources used by the cloud server in the first host are released, the released computing resources become the available computing resources of the first host again, and then the available computing resource value of the first host can be updated. For example, assuming that the computing resources of the first host include 64-core CPUs and 128G memories, the computing resources occupied by the cloud server are 4-core CPUs and 4G memories, when the computing resources used by the cloud server in the first host are not released, the available computing resource value of the first host is 60-core CPUs and 124G memories, and after the computing resources used by the cloud server in the first host are released, the available computing resource value of the first host is updated to 64-core CPUs and 128G memories.

After the cloud server is shut down, the storage resources of the cloud server are not destroyed, and only the association relation between the cloud hard disk and the first host is removed, so that the cloud application is in an independent state. In practical applications, the cloud hard disk corresponding to the cloud server may be recorded in the configuration table through the identifier of the cloud server and the identifier of the cloud hard disk, but the association relationship between the cloud hard disk and the first host is released.
In some possible implementations of the present invention, it is also possible:
and storing the network configuration information of the cloud server, and triggering the first host to delete the network configuration information.
The cloud server further has some network configuration information, such as IP (Internet Protocol) resources of the cloud server, network defense policy information, and the like, and in order that the network configuration information cannot be reset when the cloud server is restarted, the network configuration information of the cloud server may be saved, and the network configuration information may be deleted in the first host, so that the network configuration information is unbound to the first host.
Referring to fig. 4, for example, the cloud server a needs to be closed, the cloud server a is closed and destroyed in the first host, the computing resources used by the cloud server a in the first host are released, and meanwhile, the association relationship between the cloud server a and the cloud hard disk a is released, so that the purpose of releasing the resources of the cloud server is achieved.
Therefore, when the cloud server is temporarily closed, the embodiment of the invention can end the process of the cloud server and release the computing resources, such as a CPU (central processing unit), a memory and the like, used by the cloud server in the first host, and the resources of the first host can be distributed to other cloud servers for use, so that the resource utilization rate of the host is improved, and the resource waste of the host is reduced.
