[0002] The cloud computing platform, also known as the cloud platform, refers to a service based on hardware resources and software resources, providing computing, network and storage capabilities. With the continuous development of cloud computing, more and more enterprises have begun to try to use the services provided by the cloud platform to simplify the deployment of services and the unified management and use of services.

[0003] However, in the physical nodes managed by the cloud platform, three-network isolation has gradually become the standard for network deployment. Three-network isolation means that the three networks of the management network, the service network, and the storage network cannot access each other; and the management nodes in the cloud platform are all deployed on the management network, and they cannot directly access the service network where virtual machines are located in the cloud platform. Therefore, in the case of three-network isolation, the cloud platform and the bare machine cannot directly communicate, which results in that during the application deployment process of the cloud platform, the bare machine cannot be controlled to download the corresponding application installation package and deploy the application by sending commands.

[0004] Therefore, how to deploy applications on a bare machine through a cloud platform is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] An embodiment of the present invention discloses an application deployment method, device, equipment, and storage medium based on a cloud platform to deploy an application on a bare machine through the cloud platform.

[0040] See Figure 1 , a schematic diagram of the process of an application deployment method provided by an embodiment of the present invention. The method specifically includes the following steps:

[0041] S101. Receive an application deployment instruction for a target bare machine;

[0042] It should be noted that in this embodiment, the cloud platform has the function of creating a bare machine through an image, and before executing this solution, the cloud platform already has images, application center virtual machines, etc. used for deploying the bare machine. Therefore, after receiving the application deployment instruction for the target bare machine in this solution, S102 can be continued to create the target bare machine and the proxy virtual machine.

[0043] S102. Create a target bare machine and a proxy virtual machine according to the application deployment instruction; the proxy virtual machine is interconnected with the service network of the target bare machine, and the proxy virtual machine is interconnected with the service network of the application center virtual machine;

[0044] In this solution, after receiving the above application deployment instruction, the cloud platform will automatically create a proxy virtual machine according to the request parameters in the instruction. The proxy virtual machine has two network cards, which can be interconnected with the service network of the target bare machine and the service network of the application center virtual machine respectively. Then, a target bare machine is created using a specific image, and the image has been pre-adapted to the application and uploaded to the cloud platform.

[0045] S103. Send a command to the QGA of the proxy virtual machine, so that the proxy virtual machine downloads the application installation package from the application center virtual machine and deploys the application on the target bare machine.

[0046] It should be noted that QGA (qemu-guest-agent) is an ordinary application program running inside the virtual machine, and its purpose is to implement a way for the host machine and the virtual machine to interact, and this way does not depend on the network. Therefore, in this application, in order to still be able to deploy applications by sending commands in the case of network isolation, the cloud host can send commands to the physical node where the proxy virtual machine is located through the management network, so that the physical node sends commands to the QGA of the proxy virtual machine through the serial port protocol. Through this method, the cloud host in this solution can send commands to the proxy server.

[0047] Specifically, the cloud platform generally has the following steps in the process of deploying applications:

[0048] 1. Create a bare machine using a specific image, and the created bare machine is logically installed with an operating system;

[0049] 2. Control the bare machine to download the application installation package from the network by sending commands;

[0050] 3. After waiting for the application installation package to be downloaded, the cloud platform needs to control the bare machine to decompress, install, configure the application, etc. through commands, and finally realize the deployment of the application on the bare machine.

[0051] Therefore, the command sent by the cloud platform in this application to the QGA of the proxy virtual machine is specifically used for: controlling the proxy virtual machine to download the application installation package from the application center virtual machine, controlling the proxy virtual machine to transfer the downloaded application installation package to the target logic, and sending the application deployment instruction to the target bare machine through the proxy virtual machine, so as to realize the deployment of the application.

[0052] In summary, in the case of network isolation, the cloud platform can download the application installation package from the application center virtual machine through the proxy virtual machine, and realize the deployment of the application on the target bare machine by forwarding commands through the proxy virtual machine, effectively realizing the application deployment ability of the cloud platform.

[0053] See Figure 2 , another schematic flow chart of the application deployment method based on the cloud platform provided by the embodiment of the present invention, and this method specifically includes the following steps:

[0054] S201. Receive the application deployment instruction for the target bare machine;

[0055] S202. Create a target bare machine and a proxy virtual machine according to the application deployment instruction; the proxy virtual machine is interconnected with the service network of the target bare machine, and the proxy virtual machine is interconnected with the service network of the application center virtual machine;

[0056] S203. Send a download command to the QGA of the proxy virtual machine to enable the proxy virtual machine to download the corresponding application installation package from the application center virtual machine;

[0057] S204. Send a transfer command to the QGA of the proxy virtual machine to enable the proxy virtual machine to transfer the application installation package to the target bare machine;

[0058] See Figure 3 , which is a schematic diagram of an application deployment process disclosed in an embodiment of the present invention. Through Figure 3 It can be seen that in the case of network isolation, a proxy virtual machine is created. The proxy virtual machine connects to two service networks as needed. Service network 1 communicates with the bare machine cluster, and service network 2 communicates with the application center virtual machine. The management node where the cloud platform is located can control the proxy virtual machine to send commands in the form of the management network QGA. Among them, the virtual machine QGA is to install qemu-guest-agent in the virtual machine. Through this agent, the cloud platform can connect to the physical node where the proxy virtual machine is located through the management network. The physical node controls the proxy virtual machine through the serial port protocol simulated in the proxy virtual machine. In this application, through this method of sending commands to the proxy virtual machine, it is not necessary for the cloud platform to communicate with the service network of the proxy virtual machine, and it only needs to communicate with the management network of the physical machine where the virtual machine is located.

[0059] It should be noted that the application deployed on the target bare machine in this solution can be software with specific functions provided by the cloud platform based on virtual machines, etc. Taking the database service in Inspur Cloud Sea os as an example: If a user wants to obtain a 3-node database cluster service, when the Cloud Sea platform receives a request to create a database service, the Cloud Sea platform will first use a virtual machine template to create a target bare machine. After the target bare machine is created, the Cloud Sea platform will send instructions to control the proxy virtual machine to download the installation package from the Cloud Sea platform software repository and transfer it to the target bare machine. Finally, the Cloud Sea platform sends instructions to the target bare machine through the proxy virtual machine to complete the application installation and its cluster configuration. Among them, in this solution, after the proxy virtual machine downloads the corresponding application installation package from the application center virtual machine, the proxy virtual machine will uninstall the service network card that communicates with the application center virtual machine. By this method, resource waste can be avoided.

[0060] S205. Send a deployment command to the QGA of the proxy virtual machine to enable the proxy virtual machine to send the deployment command to the target bare machine and control the target bare machine to install and configure the application;

[0061] In this embodiment, when the proxy virtual machine sends the deployment command to the target bare machine, specifically, the proxy virtual machine may send the deployment command to the command converter, so that the command converter sends the deployment command to the target bare machine in the way of SSH (Secure Shell). See Figure 3 , when the cloud platform in this solution needs to send a command to the bare machine, it can send the command to the proxy virtual machine through the QGA of the proxy virtual machine, and the command converter sends the command to the bare machine in the way of SSH.

[0062] Specifically, when the command converter sends a command to the logic, the deployment command at least includes a first parameter, a second parameter, and a third parameter; among them, the first parameter is the IP (Internet Protocol) of the bare machine to be controlled, and the second parameter is the authentication information of the bare machine SSH. The command converter can use this authentication information to send the instruction to the bare machine in the way of SSH; the third parameter is the instruction to be sent to the bare machine, such as the script path and parameters that the specific bare machine system needs to run. That is to say, after receiving the deployment command, the command converter sends the instruction to the specified address of the bare machine in the way of SSH, and automatically disconnects the SSH connection with the bare machine after the command is executed. Through the above method, this application can solve the problem of application download of the bare machine and the problem of sending deployment commands under the network isolation conditions of the cloud platform.

[0063] S206. Send a control command to the QGA of the proxy virtual machine, so that the proxy virtual machine sends the control command to the deployed application on the target bare machine to control the deployed application to perform corresponding operations.

[0064] It should be noted that after the application is successfully deployed on the target bare machine in this solution, the cloud platform can indirectly control the application on the target logic to perform relevant actions through the proxy virtual machine, such as creating a database, backing up, restoring, and parameter management of the MySQL (relational database management system) application.

[0065] Here, in order to clearly illustrate this solution, a method for deploying a bare metal application cluster based on virtual proxy forwarding in a private cloud scenario is proposed. The specific implementation process is as follows:

[0066] 1) After the cloud platform receives a request to create a bare machine application, it automatically creates a proxy virtual machine according to the request parameters. This proxy virtual machine has two network cards, which can communicate with the service network of the bare machine and the service network of the application center virtual machine respectively.

[0067] 2) Create a bare machine using a specific image, and this image has been pre-adapted to the application and uploaded to the cloud platform;

[0068] 3) Wait for the proxy virtual machine to be created. After the proxy virtual machine is successfully created, the cloud platform sends a command to the proxy virtual machine through QGA to download the required software installation package from the application center virtual machine;

[0069] 4) After waiting for the installation package of the proxy virtual machine to be downloaded, the proxy virtual machine uninstalls the service network card that communicates with the application center virtual machine;

[0070] 5) After waiting for the bare machine to be created, the cloud platform sends a command to the proxy virtual machine through QGA to transfer the software installation package to the bare machine;

[0071] 6) After waiting for the installation package transfer to be completed, the cloud platform sends a command to the proxy virtual machine through QGA. The proxy virtual machine sends a command to the bare machine through a command converter for software installation and configuration;

[0072] 7) Wait for the configuration to be completed, and the software can be deployed on the bare machine;

[0073] 8) After the software is deployed, the cloud platform can indirectly control the application through the proxy virtual machine to perform relevant actions, such as creating a database, backing up, restoring, parameter management, etc. for the MySQL application.

[0074] In summary, it can be seen that the present invention effectively solves the problem of application deployment based on a bare machine under the conditions of isolation of the management network, service network, and storage network by adding an application center virtual machine and a proxy virtual machine in the cloud platform. At the same time, the proxy virtual machine can provide common management functions of the application, such as parameter management, application configuration, backup, etc., effectively improving the application management ability of the cloud platform.
