Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
First, before the technical solution of the embodiments of the present application is specifically described, a description is first given of a technical background or a technical evolution context on which the embodiments of the present application are based. With the development of cloud computing, a cloud service platform (which may be simply referred to as a cloud platform) that provides services such as computing, networking, and storage for users has emerged. In some scenarios, for example, when the user needs to enter a BIOS interface of a server to which the virtual machine belongs to set operations such as cloud disk startup, the user needs to remotely access a remote desktop of the server to which the virtual machine belongs, so as to remotely operate the server.
In the related art, a KVM (keyboard-video-mouse) function provided by a baseboard management controller (BMC, baseboard Management Controller) of a server may be used to access an embedded http micro-service of the BMC by using an IP address of the BMC, and remotely connected to a remote desktop of the server by an HTML5 or Jviewer manner, so as to implement remote operations, including entering a BIOS interface of the server to perform related operations. However, when the method is adopted to remotely access the BMC of the server to which the virtual machine belongs, the IP address of the BMC needs to be exposed to the user of the virtual machine, and the user can directly access the BMC according to the IP address of the BMC so as to execute other operations after the remote desktop is successfully connected. Since the BMC cannot arbitrate the user authority level, security problems may occur and security is poor. Based on the background, the applicant provides the remote desktop connection method through long-term research and development and experimental verification, the remote desktop connected and accessed to the server through the BMC can be realized without exposing the IP address of the BMC to the virtual machine user, and the security is high. In addition, the applicant has made a great deal of creative effort to find out the technical problems of the present application and to introduce the technical solutions of the following embodiments.
The remote desktop connection method provided in the embodiment of the present application may be applied to the remote desktop connection system 100 shown in fig. 1, and includes a terminal 102, a server 104 and a cloud platform 106. Among them, the BMC of the server 104 is deployed with proxy service and VNC (Virtual Network Console ) service. The terminal 102 communicates with proxy services deployed in the BMC of the server 104 over a network. The cloud platform 106 may communicate with the BMCs of the terminal 102 and the server 104, respectively, over a network. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, portable wearable devices, and the like.
In one embodiment, as shown in fig. 2, a remote desktop connection method is provided, which can be applied to the BMC of the server in fig. 1, and specifically includes the following steps:
and step 201, in response to a remote desktop connection request sent by the target terminal, proxy connection information is sent to the target terminal through the cloud platform.
The proxy connection information is used for indicating the target terminal to send a first remote desktop access request to the proxy service based on the proxy connection information.
In implementations, the cloud platform may be an OpenStack deployment-based cloud platform, including deployed management nodes (e.g., nodes with installed Ironic components) and control nodes (e.g., nodes with installed Nova components). The control node of the cloud platform may interface with a virtual monitor (Hypervisor) of each server, and manage virtual machines corresponding to each user through the Hypervisor, including allocating server hardware resources for the virtual machines corresponding to the users. The management node of the cloud platform may communicate with the BMCs of the servers.
When a user of the cloud platform needs to access a remote desktop of the server, a remote desktop connection request operation can be triggered on the terminal. For example, the user may access the cloud platform through the browser of the terminal, and further trigger a remote desktop connection request operation on the cloud platform operation panel displayed on the browser (such as clicking a remote desktop connection button displayed on the operation panel). And the terminal can send a remote desktop connection request to the BMC of the server through the cloud platform. Specifically, after the user triggers the remote desktop connection request operation by the terminal, the control node of the cloud platform may receive the request sent by the terminal, determine the server corresponding to the virtual machine user according to the user information (such as account information of the user logging in the cloud platform) carried in the request, and send the request to the management node, so that the management node sends the remote desktop connection request to the BMC of the server corresponding to the virtual machine user. For example, the management node may send a remote desktop connection request to the BMC via the Redfish interface.
The BMC can respond to a remote desktop connection request sent by the target terminal through the cloud platform, and send proxy connection information to the target terminal through the cloud platform. Wherein, proxy service and VNC service are deployed in the BMC of the server. Specifically, the BMC may start a VNC service process, provide an underlying micro service for remote desktop connection and operation, and start a websocket proxy service, as a VNC transit proxy, perform a conversion operation of a Web (World Wide Web) socket and a TCP (Transmission Control Protocol ) socket, and the proxy service may generate proxy connection information (such as a domain name, a uniform resource locator URL (uniform resource locator), etc.) that may be accessed by the target terminal. After receiving the remote desktop connection request sent by the target terminal through the cloud platform, the BMC can send proxy connection information generated by proxy service to a management node of the cloud platform, and then feed back the proxy connection information to the target terminal (the terminal for triggering remote desktop connection request operation by a user) through a control node of the cloud platform.
After receiving the proxy link information, the target terminal may send a first remote desktop access request to the proxy service based on the proxy connection information (e.g., URL).
In step 202, in case the first remote desktop access request is received through the proxy service, the second remote desktop access request is transmitted to the VNC service through the proxy service.
The second remote desktop access request is used for indicating the VNC service to return desktop data to the proxy service.
In an implementation, the BMC may receive, through a proxy service, a first remote desktop access request transmitted by a target terminal based on proxy connection information. After receiving the first remote desktop access request, the proxy service may transmit a second remote desktop access request to the VNC service, so that the VNC service returns desktop data, such as image, video data, and the like, of the server.
In step 203, a remote desktop connection response message containing desktop data is fed back to the target terminal through the proxy service, where the remote desktop connection response message is used to instruct the target terminal to display a remote desktop of the server based on the desktop data.
In an implementation, after receiving desktop data returned by the VNC service, the proxy service may feed back a remote desktop connection response message including the desktop data to the target terminal, so that the target terminal displays a remote desktop of the server based on the desktop data, thereby implementing remote desktop connection. The user can execute corresponding operation on the server on the remote desktop interface displayed by the target terminal, the specific operation request can be transferred to the VNC service through the proxy service, and the operation result is returned through the proxy service.
According to the remote desktop connection method, the proxy service and the VNC service are deployed on the BMC of the server, when a user triggers remote desktop connection request operation at the terminal, the remote desktop connection request can be sent to the BMC of the server through the cloud platform, so that the BMC returns proxy connection information through the cloud platform, the terminal can send a remote desktop access request to the proxy service based on the proxy connection information, the proxy service can transfer the access request to the VNC service, desktop data of the server are obtained, and remote desktop connection is achieved. According to the method, a user of the cloud platform can send a remote desktop connection request to the BMC through the cloud platform, so that the BMC returns proxy connection information, then accesses proxy service based on the proxy connection information, and switches to VNC service based on the proxy service, and remote desktop connection and access are achieved, wherein the proxy connection information is information such as an address and a port of the proxy service and does not contain key sensitive information such as an IP address of the BMC, therefore, the method can achieve remote desktop connection and access to a server through the BMC without exposing the IP address of the BMC to the user, and safety is high.
In one embodiment, the process of sending proxy connection information in step 201 specifically includes the following steps: responding to a remote desktop connection request sent by a target terminal, and acquiring proxy connection information currently stored in a database; and sending the proxy connection information to the target terminal through the cloud platform.
In implementations, a proxy service deployed in the BMC may pre-generate proxy connection information that does not include the IP address of the BMC (e.g., generate a URL from a server hostname), and store the proxy connection information in a database, such as a database of a Redfish service. When the BMC receives a remote desktop connection request sent by the target terminal through the cloud platform, the BMC can respond to the request to acquire proxy connection information currently stored in the database, and then the proxy connection information is sent to the target terminal through the cloud platform. That is, when the BMC receives a remote desktop connection request sent by the management node of the cloud platform through the Redfish interface, proxy connection information (which is effective information) currently stored in the Redfish database may be returned to the management node as response data, and then sent to the target terminal through the control node.
In this embodiment, the proxy connection information generated by the proxy service may be stored in the database, and when the BMC receives the remote desktop connection request, the proxy connection information currently stored in the database may be directly used as response data.
In one embodiment, the method further comprises the steps of: and under the condition that the agent connection information is monitored to reach the preset failure condition, generating new agent connection information through the agent service, and updating the agent connection information in the database into the new agent connection information.
In practice, the failure condition of the proxy connection information may be set in advance. For example, the failure condition may be that a connection duration of the target terminal for performing remote desktop connection based on the proxy connection information exceeds a preset duration, or that a duration of the target terminal for not performing remote desktop operation after performing remote desktop connection based on the proxy connection information exceeds a preset duration. The BMC may monitor whether the proxy connection information reaches a preset failure condition, for example, the BMC may monitor remote desktop operation and operation time performed by the target terminal, and if a time difference between an operation time of the target terminal for last operating the remote desktop and a current system time exceeds a preset threshold, consider that the proxy connection information reaches the preset failure condition. When the failure condition is reached, the BMC may generate new proxy connection information through the proxy service and update the proxy connection information in the database to the new proxy connection information. Specifically, the built-in Redfish service of the BMC may subscribe to the update time of the proxy connection information (such as URL), and when the update time of the proxy connection information is reached (such as the time of reaching the preset failure condition), synchronously send the URL requested to be updated to the proxy service, and store the new URL data in the database of the Redfish service. It can be understood that the database can only store the latest effective proxy connection information by replacing the historical proxy connection information; the latest effective proxy connection information and the past invalid proxy connection information can be stored at the same time, the state (effective and invalid) and the storage time of the proxy connection information are distinguished, and when a remote desktop connection request sent by the cloud platform is received, the currently stored effective proxy connection information is used as response data.
In this embodiment, by monitoring the failure event of the proxy connection information, when the failure condition is reached (for example, the target terminal has been connected overtime or the duration of non-operation after connection is overtime), the proxy connection information is updated in time, so that on one hand, resources can be released in time for other virtual machine users to use, the convenience of accessing the remote desktop by the cloud platform user is improved, and on the other hand, the proxy connection information is updated in time, so that the security problem caused by the fact that the proxy connection information may leak to a third party can be reduced.
In one embodiment, the method further comprises the steps of: and monitoring the state of the VNC service, and restarting the VNC service when the state of the VNC service is monitored to be a lost state.
In implementations, after the BMC starts the VNC service, the state (start-up state or loss state) of the VNC service may be monitored in real time. If the state of the VNC service is a lost state, the BMC may restart the VNC service to ensure that the VNC service is continuously in a startup state, thereby providing a guarantee for remote desktop connection and operation.
In this embodiment, by monitoring the state of the VNC service and restarting the VNC service when the VNC service is lost, the VNC service is ensured to be continuously in a startup state, and a guarantee is provided for remote desktop connection and operation.
In one embodiment, the method further comprises the steps of: and responding to an operation request aiming at the remote desktop sent by the target terminal, executing an operation instruction corresponding to the operation request, and storing an operation result as an operation log.
In implementation, the target terminal realizes remote desktop connection of the server based on the proxy connection information, after displaying an interface of the remote desktop on the target terminal, the user can perform mouse-keying operation on the interface of the remote desktop, specifically, the user can trigger an operation request for the remote desktop through the target terminal, and after receiving the operation request, the proxy service of the BMC can transfer the operation request to the VNC service, so that the VNC service executes a corresponding operation instruction based on the operation request, and returns operation result data to the target terminal through the proxy service. Meanwhile, the BMC can store the operation data of the target terminal on the remote desktop of the server as an operation log, and store the operation log corresponding to the user information, for example, the operation log can be stored in a database of a Redfish service, so that an administrator can inquire the historical operation data of each virtual machine user on the remote desktop of the server.
In this embodiment, the operation data of each user on the remote desktop is stored as the operation log, so that an administrator can query the historical operation data of each virtual machine user on the remote desktop of the server, thereby facilitating management.
The embodiment of the application also provides a remote desktop connection method, as shown in fig. 3, which can be applied to the terminal in fig. 1, and specifically includes the following steps:
The remote desktop connection request is used for indicating the BMC to feed back proxy connection information through the cloud platform.
In an implementation, when a user of the cloud platform needs to access a remote desktop of the server, a remote desktop connection request operation may be triggered on the terminal. For example, the user may access the cloud platform through the browser of the terminal, and further trigger a remote desktop connection request operation on the cloud platform operation panel displayed on the browser (such as clicking a remote desktop connection button displayed on the operation panel). Therefore, the terminal can send a remote desktop connection request to the BMC of the server through the cloud platform. The remote desktop connection request is used for indicating the BMC to feed back proxy connection information through the cloud platform.
