Referring to fig. 1, a schematic flow diagram of a method for managing a QGA service based on a cloud host provided in an embodiment of the present invention includes:
s101, initiating an installation information acquisition request to a libvirt service through a Nova-computer service to inquire installation information of cloud hosts on all computing nodes in a cluster; updating the database according to the installation information of each cloud host; the installation information includes: installed and uninstalled QGA services;
s102, displaying the installation information of each cloud host in a corresponding UI page;
in this embodiment, a cloud host refers to a complete computer system with complete hardware system functions, which is simulated by software and runs in a completely isolated environment. When the installation information of the QGA service of each cloud host is obtained, an installation information obtaining request is sent to the libvirt service through the Nova-computer service so as to inquire the installation information of the cloud hosts on all computing nodes in a cluster; and updating the database according to the installation information of each cloud host.
Nova is a raw and core component in OpenStack, mainly providing computing services, and managing a virtual machine to respond to a service request made by an OpenStack user. The Nova project is used for interacting with a large number of other OpenStack services and internal components, and Nova must cooperate with each service component to respond to a request of a user to run a virtual machine. Nova-computer service is a computing node service in OpenStack that starts a cloud host, and Libvirt is a service that provides a convenient way to manage a collection of virtual machines and other virtualization functions, such as management of storage and network interfaces. In this scheme, when the Nova-computer service periodically initiates a request to the libvirt service, traverses cloud hosts on all computing nodes in the cluster, and queries whether the cloud hosts install the QGA service, in this embodiment, the process specifically includes: the Nova-computer service issues a request to a libvirt service through a timer, IP splicing is carried out on computing nodes obtained from a Nova database through qemu + tcp, connection with the computing nodes is established to traverse cloud hosts on all the computing nodes in a cluster, root passwords of the cloud hosts are obtained through the Nova database, the cloud hosts on the computing nodes are logged in, whether the QGA service is installed on the cloud hosts on a cloud platform or not is inquired, whether the cloud hosts are installed or not can be judged by executing rpm-qa | grep qemu in the cloud hosts, when a return result indicates that the QGA service is installed on the cloud hosts, and when the return result is empty, the fact that the QGA service is not installed on the cloud hosts is indicated.
Moreover, in this embodiment, a database is also required to be provided, where the database is used to include installation information of the QGA service of each cloud host; therefore, after the installation information is acquired, the database needs to be updated according to the installation information. For example: adding QGA fields in the Nova database instances table, wherein the meaning of the fields indicates whether the cloud host installs the QGA service, triggering to update QGA fields in the Nova database instances table by obtaining a return value in the last step, if the cloud host is found not to install the QGA service, updating the value of the Nova database instances table QGA field to be 0 (indicating that the cloud host does not install the QGA service), if the cloud host is found to install the QGA service, updating the value of the Nova database instances table QGA field to be 1 (indicating that the cloud host installs the QGA service), and returning through the Nova-api service, displaying relevant information on the details page of the cloud host to prompt a user, such as: whether the cloud host is provided with the prompt information of the QGA service or not is prompted, and if the cloud host is not provided with the QGA service, the installation prompt can be displayed. The cloud host detail page is a UI (user interface) interface corresponding to the cloud host, a user can determine whether to execute cloud host operation according to information displayed on the cloud host detail page, and the Nova-api provides a computing service interface for the user on a control node in the OpenStack.
And S103, if the installation information of the first cloud host is that the QGA service is not installed, displaying an installation prompt in a UI page of the first cloud host so as to install the corresponding QGA service for the first cloud host through the installation prompt.
In this embodiment, a host that does not have the QGA service installed is referred to as a first cloud host. In the related scheme, if a large number of cloud hosts on the cloud platform are found without installing the QGA service, the cloud hosts need to be manually installed, and for different operating systems and different versions, the versions for installing the QGA service are different, the installation method is also different, the installation of software also has a certain professional ability requirement on users, although the network is full of a large number of courses for installing the software, the users need to spend a large amount of time trying a feasible method under the condition that the users do not clearly know the software, and thus, the operation of the users is not friendly. Therefore, in the scheme, after the database data is updated, the result is returned through the Nova-api service, the relevant information is displayed in the detail page of the cloud host of the cloud platform, and for the cloud host without the QGA service, the QGA service can be installed by a user in an auxiliary or assisted mode of displaying the installation prompt.
Specifically, in the present embodiment, the installation prompts displayed in the UI page of the first cloud host include an active installation prompt and an automatic installation prompt. If a trigger instruction corresponding to the active installation prompt is received, acquiring a QGA service installation prompt corresponding to an operating system of the first cloud host; and displaying the QGA service installation prompt in a UI interface so that the user can manually install the QGA service according to the QGA service installation prompt. If a trigger instruction corresponding to the automatic installation prompt is received, automatically installing corresponding QGA service in the first cloud host through a QGA installation package matched with the first cloud host, wherein the process specifically comprises the following steps: judging whether a target ISO mirror image of a QGA installation package matched with the first cloud host exists in the Glance mirror image service, if so, mounting the target ISO mirror image to the first cloud host, and executing an automatic installation script in the first cloud host to install the QGA service; and if the target ISO mirror image does not exist in the cloud platform resource sharing server, acquiring the target ISO mirror image from the cloud platform resource sharing server, mounting the target ISO mirror image to the first cloud host, and executing an automatic installation script in the first cloud host to install the QGA service.
That is to say, when the user installs the QGA service, the user may select active installation or automatic installation, and in this embodiment, the active installation prompt and the automatic installation prompt may be displayed in the UI interface in a button manner. If the user wants to actively install the QGA service, clicking a button corresponding to the active installation prompt in a UI (user interface), displaying the QGA service installation prompt after the system receives a trigger instruction sent by the user clicking the button, wherein an installation method corresponding to an operating system of the first cloud host is recorded in the QGA service installation prompt, and the installation method displayed in the QGA service installation prompt can be various, so that the user can select a proper installation method from the installation method to install the QGA service on the first cloud host.
If the user wants to automatically install the QGA service, clicking a button corresponding to the automatic installation prompt in a UI interface, and after receiving a trigger instruction sent by the user clicking the button, triggering the automatic installation of the QGA service logic, such as: firstly, whether an ISO mirror image of a QGA installation package matched with a first cloud host exists in the Glance mirror image service is checked, the mirror image also comprises a QGA installation script, if the ISO mirror image does not exist, the ISO mirror image of the QGA installation package is pulled from a cloud platform resource sharing server and uploaded to the Glance mirror image service, after the operation is completed, the first cloud host is mounted with the ISO mirror image of the QGA installation package in the cloud platform Glance mirror image service, an automatic installation script is executed in the first cloud host to install the QGA service, and the QGA service is started.
If the user selects the automatic installation of the QGA service, the value of the Nova database instances table QGA needs to be updated to 1 after the user is guided to install the QGA service; when the user selects the automatic installation of the QGA service, similarly, after the QGA service is installed, the value of the Nova database instances table QGA needs to be updated to 1. The cloud platform is a cloud computing service platform which is based on hardware resources and software resource services and provides computing, network, storage and other capabilities. The Glance is a set of virtual machine image searching and retrieving system, supports various virtual machine image formats, and has the functions of creating and uploading images, deleting images and editing basic information of the images.
It should be noted that, after the QGA service is installed in the cloud host, some abnormal scenes may also occur, which may cause the QGA service to be turned off or prohibited, and at this time, the user is unaware of the situation, and the user lacks the ability to timely sense the abnormality of the QGA service of the cloud host, and performs operations such as online snapshot on the cloud host, which may also cause operation failure, thus causing great inconvenience to the user in using the cloud platform, and also being not beneficial to popularization of the cloud platform. Therefore, in the present embodiment, the service state of the QGA service in each cloud host may also be periodically detected; and if a second cloud host with an abnormal service state exists, displaying abnormal prompt information of the second cloud host in a UI (user interface) page corresponding to the second cloud host, restarting the QGA service of the second cloud host, and continuously executing the step of periodically detecting the service state of the QGA service in each cloud host.
Specifically, after the QGA service is installed on the cloud host on the cloud platform, timing monitoring QGA state logic can be triggered, a request QGA service is initiated at regular time through Libvirt service to execute a guest-ping instruction, when a return result is null, the QGA service is normal, and when the return result is error, the QGA service is abnormal; when monitoring that the QGA service of the cloud host is abnormal, firstly updating the QGA service abnormality of the cloud host on a cloud platform interface, triggering to restart the QGA service in the cloud host, after the service is restarted, executing a guest-ping instruction by the QGA service, returning a null value to indicate that the service is normal, and updating the QGA service state of the cloud host to be normal on the cloud platform interface, so that the operation failure of a user on the cloud host is avoided.
Referring to fig. 2, an overall flow diagram of a method for managing a QGA service according to an embodiment of the present invention includes: s201: the Nova-computer service issues a request, S202: the Libvirt service detects whether the cloud host is provided with the QGA service; s204: if the QGA service is installed, updating the database; s203: if the QGA service is not installed, updating the database, prompting a user to install the QGA service or automatically installing the QGA service on a UI (user interface), and executing S204 to update the database after the QGA service is installed; s205: triggering and monitoring the QGA service state, S206: and modifying the QGA service state on the UI interface, calling Libvirt service to restart the QGA service if the QGA service state is abnormal, and updating the QGA service state on the UI interface after the QGA service state is normal.
In conclusion, the scheme realizes a more universal cloud platform for automatically detecting whether the cloud host is provided with the QGA service, automatically installing the QGA service and automatically monitoring the QGA service, the Nova-computer service issues a request through a timer, and the Libvirt service automatically detects whether all the cloud hosts on the cloud platform are provided with the QGA service; if the QGA service is not installed, the appropriate QGA installation package mirror image is retrieved from the Glance service and is mounted to the cloud host through matching the system version of the cloud host, and the automatic installation of the QGA in the cloud host is triggered; the method can also be used for periodically initiating a request QGA service to execute a guest-ping instruction through Libvirt to monitor the QGA service state of the cloud host on the cloud platform, displaying the QGA service state in the cloud host details on the cloud platform interface, and restarting the QGA service when the QGA service is found to be abnormal so as to enable the service to be recovered to be normal. It is thus clear that this scheme has increased detection, installation, control QGA mechanism for the cloud platform, can realize automatic patrolling and examining to platform cloud host computer, detects whether the cloud host computer installs QGA service, and automatic installation QGA service and control QGA service in time discover unusually, accomplish visual management, and the user can be early discovery solution problem, has strengthened the robustness of cloud platform, has also brought the improvement to user experience.
