[0021] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0023] Based on the above objectives, a first aspect of an embodiment of the present invention provides an embodiment of a method for out-of-band operating system deployment. Figure 1 FIG. 2 is a schematic diagram of an embodiment of a method for out-of-band operating system deployment provided by the present invention. Figure 1 As shown, the embodiment of the present invention includes the following steps:

[0024] S01. Maintain the information of several devices to be deployed on a preset device template and import the device template;

[0025] S02, judging whether out-of-band operating system deployment can be performed on each device to be deployed based on the information in the device template;

[0026] S03. If the device to be deployed can perform out-of-band operating system deployment, customize a configuration file for the device to be deployed, and perform image packaging based on the configuration file;

[0027] S04, mounting the image in an out-of-band manner and deploying the operating system; and

[0028] S05. Obtain a screenshot of the operating system deployment interface of the device to be deployed in real time, and perform image processing and text recognition on the screenshot to obtain real-time data of the operating system deployment.

[0029] In this embodiment, it includes a device template download and import module, a device detection module, a kickstart file customization module, a batch OS deployment module, a CRNN analysis module, and an OS deployment information reporting module. The device template download and import module is used to conveniently process batch devices and perform OS batch deployment; the device detection module is used to detect whether the current device supports OS deployment, and detect in advance to avoid useless work; the kickstart file customization module is used to provide users with configuration files for automatic OS deployment; the batch OS deployment module is used to execute batch OS deployment tasks; the CRNN analysis module accurately and efficiently analyzes the OS deployment process and results; the OS deployment information reporting module is used to report the OS deployment process and results analyzed by CRNN to the user.

[0030] In some embodiments of the present invention, obtaining a screenshot of the operating system deployment interface of the device to be deployed in real time, and performing image processing and text recognition on the screenshot to obtain real-time data of the operating system deployment includes: capturing the operating system deployment interface in real time through an out-of-band screenshot interface, and uploading the captured screenshot to an image repository for classified storage based on serial number and time; performing image information text recognition analysis on the screenshots in the image repository through an image algorithm, and formatting the analysis results to obtain real-time data of the operating system deployment.

[0031] In this embodiment, the CRNN analysis module enables users to understand the process, progress and results of OS deployment in real time. First, the OS deployment interface is captured in real time through the device's out-of-band screenshot interface, and the image is uploaded to the image repository. The images are classified and stored according to the upload sequence number and time.

[0032] In some embodiments of the present invention, performing image information text recognition analysis on screenshots in an image repository using an image algorithm includes: extracting sequence features in image convolution features of the screenshots using a CRNN algorithm; and aligning the recognized text using a CTC algorithm.

[0033] In this embodiment, a stack-shaped deep bidirectional structure is used in CRNN; the image is scaled to 32*W*3 (W represents any length) with a fixed aspect ratio; then it becomes 1*(W / 4)*512 after passing through CRNN, and T=(W / 4) is set for LSTM to input the features into LSTM. Then LSTM further extracts the sequence features in the image convolution features, and finally introduces CTC to solve the problem of character alignment failure; the CRNN analysis module detects the images in the storage library and performs image information text recognition analysis, and the analyzed data is formatted and then cached according to different devices.

[0034] In some embodiments of the present invention, determining whether each device to be deployed can perform out-of-band operating system deployment based on information in a device template includes: determining whether the device to be deployed is a deployable device, a risky device, or an undeployable device based on information in the device template; if the device to be deployed is a deployable device, confirming that the device to be deployed can perform out-of-band operating system deployment; if the device to be deployed is a risky device, informing the user and determining whether the out-of-band operating system deployment can be performed based on user instructions; if the device to be deployed is an undeployable device, it is deemed that the device to be deployed cannot perform out-of-band operating system deployment.

[0035] In this embodiment, the device detection module is used to detect and screen devices that cannot be deployed out of band, and users are notified in advance to avoid wasted work. The device detection module starts to detect after the user imports the device. The device detection is ultimately divided into three categories: devices that can be deployed with OS, devices that have risks in OS deployment, and devices that cannot be deployed with OS.

[0036] In some embodiments of the present invention, judging whether out-of-band operating system deployment can be performed on each device to be deployed based on information in the device template includes: judging the level of factors affecting out-of-band operating system deployment based on information in the device template; if the level of factors affecting out-of-band operating system deployment is a first-level influencing factor, alerting the user to perform maintenance; if the level of factors affecting out-of-band operating system deployment is a second-level influencing factor, collecting the second-level influencing factors of the device to be deployed, and performing level judgment based on the second-level influencing factor model, sending the judgment result to the user and waiting for user instructions; if the level of factors affecting out-of-band operating system deployment is a third-level influencing factor, analyzing and predicting the third-level influencing factors of the device to be deployed to determine whether there is a risk.

[0037] In this embodiment, important factors affecting the deployment of the operating system are analyzed, such as RAID, hard disk, out-of-band network status, accuracy of server username and password, and server performance (memory, CPU, etc.). The above factors are classified, such as out-of-band network and service password accuracy, which will definitely cause the failure of the deployment of the operating system as the first-level factor f1, RAID, hard disk and other factors with relatively large impacts are classified as the second-level factor f2, and server performance and other factors with relatively small impacts are classified as the third-level factor f3.

[0038] The first-level influencing factors are manually maintained by the user, so the device can be imported for verification. The f1 factor can be verified to immediately warn the user after importing and modify and maintain the problem.

[0039] The secondary influencing factors collect information about the device f2 factors when the user issues the OS batch deployment task. A large amount of data will be used to investigate the f2 factors, and different values ​​of the f2 factors will be randomly matched and combined to simulate OS deployment, and finally an f2 factor model will be formed. The model is divided into input parameters and output parameters. The input parameters are the actual device f2 influencing factors, and the output parameters are the OS deployment success level. The success levels are divided into high, medium, and low. The model analyzes the device OS deployment success rate through input parameter matching. The success rate will set a success rate range when the model is created in the early stage, for example, 100-70 is high, 70-40 is medium, and less than 40 is low. The return value will be used to warn the customer and give the reason for the warning. The user can choose to continue or terminate the installation based on his own judgment at the first level of the warning.

[0040] The third-level influencing factors are collected in real time after the device is imported. When users perform batch OS deployment, the server f3 factors in the latest period will be analyzed. Based on the analysis of this period, the server performance trend during the OS deployment period can be predicted. If there is a risk, the server will inform the user in advance and prompt the risk. The user can choose to give up or force OS deployment according to their own situation.

[0041] In some embodiments of the present invention, the information of several devices to be deployed is maintained on a preset device template, and importing the device template includes: creating a device template based on the out-of-band IP, user name, password, system IP to be configured, subnet mask, network management, and host name; maintaining the information of several devices to be deployed on the device template.

[0042] In this embodiment, the device template download and import module is used to download the device template in the visual interface, and the devices that are about to be deployed in batches of out-of-band OS are maintained in the device template. This includes the out-of-band IP, user name, password, system IP to be configured, subnet mask, gateway, host name, etc. After the device template is maintained, the device is imported with one click. The user can view the countdown devices in the visual interface and edit a certain device, etc., providing users with a convenient and fast device maintenance method.

[0043] In some embodiments of the present invention, the method further includes: acquiring real-time data in real time, and reporting the real-time data to a user.

[0044] In this embodiment, the information data of the crnn analysis module is reported to the user in real time through the OS deployment information reporting module, so as to avoid the black box operation that the user cannot understand the process, progress and results of OS deployment. The data analyzed and processed by CRNN is reported to the user in real time from the cache storage, and the user can view the OS deployment status in real time on the visual interface.

[0045] In some embodiments of the present invention, customizing a configuration file for a device to be deployed includes: providing a custom file interface for a user through a visual interface.

[0046] In the present embodiment, the kickstart file customization module is used to simulate the installation visual interface of the real system, and each step provides the user with reasonable suggestions based on our installation experience. Many users do not know much about the configuration of the automatic deployment file of the operating system, and often the files configured by themselves always have different problems during the installation process. The kickstart file customization module finally generates the automatic installation configuration file required by the user. At the same time, a file editable interface is provided for operation and maintenance personnel with certain experience, and the user can edit the kickstart file through a visual file editor.

[0047] In some embodiments of the present invention, mounting the image in an out-of-band manner and performing operating system deployment includes: mounting the image in an out-of-band manner according to the device to be deployed, restarting and performing operating system deployment.

[0048] In this embodiment, the batch OS deployment module is used to package the kickstart file customized by the user, and the IP and hostname configuration scripts generated according to the device import information into a new image. The out-of-band image is mounted according to the out-of-band mounting method of the device, and after the image is mounted, the system is restarted and the operating system is automatically deployed.

[0049] It should be particularly pointed out that the various steps in the various embodiments of the above-mentioned out-of-band operating system deployment method can be cross-linked, replaced, added, and deleted. Therefore, these reasonable permutations, combinations and transformations of the out-of-band operating system deployment method should also fall within the scope of protection of the present invention, and the scope of protection of the present invention should not be limited to the embodiments.
