[0024] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0025] In addition, the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0026] Please refer to Figure 1 As shown, the cloud virtual machine background maintenance method provided by the present invention includes:

[0027] S101 updates basic information associated with the virtual machine to a fixed static file according to a predetermined period;

[0028] S102 uses the network addresses of different maintenance module objects as identification codes, establishes connections through binding or mapping according to the identification codes, and completes the construction of the virtual machine entity;

[0029] S103 generates a command set according to the basic information in the static file and the association relationship between the virtual machine entity and the maintenance module;

[0030] S104: filtering the command set according to preset rules to generate recommendation data, and performing background maintenance according to the recommendation data.

[0031] The basic information includes a virtual machine identifier, an instance identifier, a virtual machine name, a virtual machine status, a host machine name, and a network address.

[0032] In actual work, for cloud environments with large deployment scales, many background commands have poor execution efficiency. By periodically executing the nova list--all--fields instance_name,name,status,host,networks command, the basic information is saved and updated to a fixed static file. The update frequency can be set to 1-15 minutes according to the actual situation to control the additional consumption of system resources and keep the configuration data fresh. The basic information includes: virtual machine identifier vmID, instance identifier instanceID, virtual machine name vmName, virtual machine status vmStatus, host name hostName, network address vmIP. Among them, vmID is a uuid universal unique identification code format, including disks, network cards, specifications, mirrors and other objects, all of which use uuid as a unique identifier. Although the probability of duplication is almost zero, it is very difficult to read and remember; for this reason, the present invention adopts an associated command method to help command selection, and the specific implementation method will be described in detail in the subsequent embodiments, so it will not be listed one by one here.

[0033] Please refer to Figure 2 As shown, in one embodiment of the present invention, generating a command set according to the basic information in the static file and the association relationship between the virtual machine entity and the maintenance module includes:

[0034] S201 obtains a virtual machine identifier according to the basic information, virtual machine name and network address in the static file;

[0035] S202 generates a virtual machine power on / off command, a restart command, and a command for obtaining a console port address according to the virtual machine identifier.

[0036] Furthermore, generating a command set according to the basic information in the static file and the association relationship between the virtual machine entity and the maintenance module may also include: obtaining basic information of the virtual machine according to novaID query, and generating a command set according to the basic information according to preset rules. Figure 3 As shown, generating a command set according to the basic information and preset rules includes:

[0037] S301 obtains image list information according to the virtual machine specification information, and generates a specification change command through the image list information and pre-stored configuration information;

[0038] S302 generates a reinstall operating system command according to the virtual machine image;

[0039] S303 obtains corresponding disk-related information according to the virtual machine disk information query, and generates a disk snapshot command and a disk unmount command according to the disk-related information.

[0040] In another embodiment, generating a command set according to the basic information in the static file and the association relationship between the virtual machine entity and the maintenance module may include: querying the corresponding port identifier and subnet identifier according to the virtual machine address information, and generating a port and subnet information query command.

[0041] In summary, in the association command generation link, the virtual machine entity constructed in step S102 is mainly used. Since objects in different modules use uuid as an identifier, the present invention establishes connections between different objects through binding or mapping, thereby constructing a virtual machine entity, and various uuid values ​​establish connections as key nodes in this relationship.

[0042] Therefore, in actual work, the following command set can be generated based on the above relationship:

[0043] 1. Based on the regularly updated and saved basic information, you can quickly query the virtual machine ID vmID using the virtual machine address vmIP and vmName, and then generate commands such as virtual machine power on / off, restart, and obtain the console VNC url address:

[0044] nova start $vmID;

[0045] nova stop $vmID;

[0046] nova reboot --hard $vmID;

[0047] nova get-vnc-console$vmID novnc;

[0048] 2. Based on the novaID, use the nova show$novaID command to query various basic information of the virtual machine, including:

[0049] Virtual machine flavor ID;

[0050] Virtual machine image imageID;

[0051] Virtual machine disks diskID1, diskID2, diskID3...;

[0052] 3. According to the flavorID of the virtual machine specification, use the nova flavor-list command to query the image list flavorList. Combined with the information recorded by the configuration management system, you can generate a command for specification change. For example, for a 4c8g virtual machine, you can provide 2c4g, 8c16g and other specification change command recommendations:

[0053] nova resize$vmID$flavorID1 (2c4g);

[0054] nova resize$vmID$flavorID2 (8c16g);

[0055] 4. Based on the virtual machine image imageID, you can generate a command to reinstall the operating system:

[0056] nova rebuild$vmID$imageID;

[0057] 5. According to the virtual machine address vmIP, you can query the corresponding port identifier portID and subnet identifier netID through neutron port-list, generate port and net information query commands, and query port status, subnet configuration and other information:

[0058] neutron port-show $portID;

[0059] neutron net-show $netID;

[0060] 6. Based on disk ID1, you can query the basic information of the disk through the command cinder show $diskID1, and generate commands such as creating a disk snapshot and uninstalling a disk:

[0061] cinder snapshot-create$diskID1;

[0062] nova volume-detach$vmID$diskID1;

[0063] Since the commands of each module have many parameters and usages, they are not listed one by one here. Relevant technicians in this field can make corresponding adjustments according to actual conditions, and the present invention is not further limited here.

[0064] In one embodiment of the present invention, filtering the command set by a preset rule to generate recommendation data includes:

[0065] Obtain usage habit records, and filter the command set according to the usage habits to generate recommendation data; wherein the usage habit records include: obtaining executed command records in the historically generated command set, and generating usage habit records according to the command records.

[0066] Furthermore, filtering the command set by preset rules to generate recommended data may also include: filtering the command set by preset search keywords to generate recommended data. In actual work, since each module has dozens of commands and multiple parameter usages, if it is simply listed, the output information will be very complicated and difficult to view and search in the command line window. Therefore, the following three methods are provided for filtering.

[0067] 1. Recommended command sets can be maintained based on usage habits, ranging from a dozen to dozens. The acquisition of usage habits may include: recording the actual execution records after the generated commands, recording the user's usage habit data, and bolding, highlighting, and pinning frequently used commands for recommendation based on the records.

[0068] 2. There are only a few core modules with short names that are easy to remember. By appending the module name, only related commands for one or more modules can be generated to reduce the output content; each module command is displayed in a category and marked with different colors for quick positioning.

[0069] 3. By searching for keyword parameters, you can output only commands containing get or show.

[0070] Please refer to Figure 4 As shown, the present invention also provides a cloud virtual machine background maintenance device, which includes an update module, a construction module, a command generation module and a processing module; the update module is used to update the basic information associated with the virtual machine to a fixed static file according to a predetermined period; the construction module is used to use the network addresses of different maintenance module objects as identification codes, and establish a connection through binding or mapping according to the identification codes to complete the construction of the virtual machine entity; the command generation module is used to generate a command set according to the basic information in the static file and the virtual machine entity according to the association relationship of the maintenance module; the processing module is used to filter the command set through preset rules to generate recommended data, and perform background maintenance according to the recommended data.

[0071] In the above embodiment, the command generation module includes a query unit, which is used to query and obtain a virtual machine identifier according to the basic information, virtual machine name and network address in the static file; and generate a virtual machine power on / off command, a restart command and a command to obtain the console port address according to the virtual machine identifier. In actual work, the specific implementation of the cloud virtual machine background maintenance device has been described in detail in the above embodiment, and will not be listed in detail here.

[0072] The beneficial technical effect of the present invention is that it solves the pain points of having too many background maintenance commands, being inconvenient to remember, and being cumbersome to input under the Openstack virtualization framework, and provides a method for quickly generating recommended commands. It is easy to use, and only requires the virtual machine IP address or the virtual machine name as a parameter to generate a large number of recommended commands, without the need to enter subsequent commands through cumbersome queries and piecing together. Derived commands are displayed by category according to different modules, and highlighting is supported for easy and quick positioning and retrieval. A customized module method is provided to only display the derived commands of one or some modules, and command keywords can be searched and filtered. Statistical analysis is performed on the commands actually used by users, and commonly used commands are recommended at the top to improve usage efficiency.
