Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 flowchart of a cloud host function expansion method according to an embodiment of the present disclosure.
The cloud host function expansion method provided by the embodiment of the application can comprise the following steps:
step S101: and acquiring function expansion configuration information for performing function expansion on the target cloud host.
In practical application, function extension configuration information for performing function extension on a target cloud host may be obtained first, and the type and content of the function extension configuration information may be determined according to a function to be extended by the target cloud host, for example, for a target cloud host requiring a cryptographic function to be extended, the function extension configuration information of the target cloud host is configuration information for implementing the cryptographic function. In a specific application scenario, the function extension configuration information may be directly transmitted to the execution main body of the cloud host function extension method provided by the present application from the outside, or may be directly generated by the execution main body of the cloud host function extension method provided by the present application, and the like, and the present application is not specifically limited herein.
Step S102: and acquiring system configuration information of the target cloud host.
In practical application, after the function extension configuration information for performing function extension on the target cloud host is obtained, the system configuration information of the target cloud host can be obtained, and specifically, the system configuration information stored in the database of the target cloud host can be read.
Step S103: and adding the function extension configuration information into the system configuration information to generate target configuration information.
In practical application, after the system configuration information of the target cloud host is acquired, the function extension configuration information can be added to the system configuration information, so that the target configuration information is generated.
Step S104: and sending a virtualization control instruction to the target cloud host, so that the target cloud host updates the target configuration information to a system configuration file of the target cloud host through a virtualization method.
In practical application, after the function expansion configuration information is added to the system configuration information and the target configuration information is generated, the target cloud host cannot apply the target configuration information at this time, so that the target cloud host cannot realize function expansion, at this time, a virtualization control command can be sent to the target cloud host, so that the target cloud host can update the target configuration information to a system configuration file of the target cloud host through a virtualization method, and after the target cloud host updates the target configuration information to a system configuration file of the target cloud host, the target cloud host can realize a corresponding expansion function based on the function expansion configuration information because the system configuration file contains the function expansion configuration information.
According to the cloud host function expansion method, function expansion configuration information for performing function expansion on a target cloud host is acquired; acquiring system configuration information of a target cloud host; adding the function expansion configuration information into the system configuration information to generate target configuration information; and sending a virtualization control instruction to the target cloud host, so that the target cloud host updates the target configuration information to a system configuration file of the target cloud host through a virtualization method. According to the cloud host function expansion method, the function expansion configuration information is added into the system configuration information of the target cloud host to generate the target configuration information, and the target cloud host is controlled to update the target configuration information into the system configuration file of the target cloud host through the virtualization method, so that the target cloud host can realize function expansion.
According to the cloud host function expansion method, in order to improve the function expansion efficiency of a target cloud host, in the process of sending a virtualization control command to the target cloud host so that the target cloud host updates target configuration information to a system configuration file of the target cloud host through a virtualization method, the target configuration information can be updated to a database of the target cloud host; and sending a virtualization synchronization control instruction to the target cloud host to enable the target cloud host to synchronize the database through a virtualization method, and further enable the target cloud host to update the target configuration information into the system configuration file. That is, the target configuration information may be updated to the database of the target cloud host, and then the target cloud host is controlled to synchronize the database through the virtualization technology, so that the target cloud host can update the target configuration information to its own system configuration file easily and quickly.
According to the cloud host function expansion method, in order to improve the function expansion success rate of the target cloud host, after the target configuration information is updated to the database of the target cloud host, before the virtualization synchronization control command is sent to the target cloud host, a restart command can be sent to the target cloud host, so that the target cloud host can restart the target cloud host. That is, after the target configuration information is updated to the data block of the target cloud host, the restart instruction may be sent to the target cloud host first, so that the target cloud host restarts itself, and since the target cloud host restarts, database synchronization may be performed.
In the cloud host function expansion method provided by the application, in order to facilitate generation of target configuration information, in the process of adding the function expansion configuration information into the system configuration information and generating the target configuration information, the system configuration information can be displayed in a preset list; and adding the function expansion configuration information into a preset list, and taking the preset list as target configuration information. The format of the preset list can be determined according to actual needs, for example, the format of the preset list can be determined according to system configuration information; the manner of displaying the system configuration information in the preset list may also be determined according to actual needs, for example, displaying the system configuration information in the preset list in sequence according to the order of the system configuration information, or collectively displaying the associated configuration information in the system configuration information in the preset list, and the like.
In order to improve the rate of generating the target configuration information, in the process of adding the function extension configuration information to the system configuration information and generating the target configuration information, the function extension configuration information may be added to the tail of the system configuration information to generate the target configuration information. That is, the function expansion configuration information can be added to the tail part of the system configuration information, so that the generated target configuration information does not have the condition that the function expansion configuration information is added into certain system configuration information, that is, the condition that the function expansion configuration information breaks down certain system configuration information does not occur, and the integrity of each system configuration information is ensured; and only the function expansion configuration information is added to the tail part of the system configuration information, the target configuration information can be generated, and the method is convenient and quick.
According to the cloud host function expansion method, when the system configuration information of the target cloud host is obtained, the system configuration information of the target cloud host can be obtained through the OpenStack cloud management platform. Specifically, a corresponding API (application programming Interface) Interface may be set on the target cloud host through the OpenStack cloud management platform, so as to manage and control the system configuration file of the target cloud host through the API Interface. It should be noted that, in practical applications, the target configuration information may also be updated to a data block of the target cloud host through the API interface, and the like.
According to the cloud host function expansion method provided by the application, when the virtualization control instruction is sent to the target cloud host so that the target cloud host updates the target configuration information into the system configuration file of the target cloud host through the virtualization method, the Libvirt virtualization control instruction can be sent to the target cloud host so that the target cloud host updates the target configuration information into the system configuration file of the target cloud host through the Libvirt virtualization method. That is, the target cloud host can be controlled to quickly update the target configuration information to the system configuration file of the target cloud host through the Libvirt virtualization method.
