Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a cloud computer control method, a cloud computer control device and a cloud computer control medium.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
In the application scene of the cloud computer such as the internet bar, the cloud computer cannot store data and files because the storage device such as the hard disk does not exist, but the process of storing the files still needs to be executed when the user control system is shut down or restarted, so that the shutdown time of the cloud computer is prolonged. In order to reduce the shutdown or restart time of the cloud computer, the application provides a cloud computer control method, which includes the steps of firstly obtaining a login process of a system, writing a dynamic link library into the login process, obtaining a shutdown operation instruction or a restart operation instruction by using the dynamic link library after detecting the operation (such as shutdown or restart) of a user control system, and controlling a hardware driver to execute the obtained operation instruction by using a cleaning function. It can be understood that, in the present application, the cloud computer is a client operated by the client using the cloud computing service, and includes, but is not limited to, smart devices such as a smart phone, a tablet computer, a notebook computer, or a desktop computer.
It can be understood that the computer shutdown process includes three stages, namely, a soft protection stage, a hard protection stage and a power-off stage, wherein in the soft protection stage, the computer system ends an application program opened by a user, saves setting information and file information of the user, and stops partial processes of system services and an operating system; in the hard protection stage, the computer system controls the computer hardware to reset; and after the hard protection stage is finished, the computer system controls the power management module to cut off the power supply of each hardware device connected with the mainboard.
In specific implementation, when a user triggers a shutdown operation, the system usually calls an ExitWindowsEx function to realize shutdown; when the Csrs acquires that the ExitWindowsEx function is successfully called, sending a shutdown instruction to an application program window belonging to a system login process (Willogon process); and sending a shutdown instruction (WM _ QUERYENDSESSION instruction or WM _ ENDSESSION instruction) to each system process, wherein if an unclosed process still exists after a preset time from the moment when the csrss process sends the shutdown instruction, the unclosed process needs to be manually closed by a user or forcibly closed by the system process. The login process winlogo calls a cleaning function NtShutdownSystem to shut down the drive and other subsystems and to reset the hardware of the computer system, e.g. to reset the head of the disk, to stop the hardware driver, etc. And finally, disconnecting the power supply of each hardware device to complete the shutdown process.
Fig. 1 is a flowchart of a cloud computer control method provided in the present application, and as shown in fig. 1, the system control method includes:
s10: and acquiring a login process of the system, and writing a dynamic link library into the login process.
It can be understood that the function for searching for a login Process mentioned in this embodiment may use a CreateToolhelp32Snapshot function, a Process32First function, and a Process32Next function of the system itself, or may be written by an administrator, and only needs to ensure that the function can implement a function of searching for a login Process in each running Process, where the searching manner may be searching according to a Process name, or searching according to a Process ID, and is not limited herein. Similarly, the function for opening the login process mentioned in this embodiment may be an OpenProcess function, or a function may be written by an administrator, and it is only necessary to ensure that the function can open the login process.
The application scenarios of the scheme provided by the present application include, but are not limited to, computer devices of a Window system and a Linux system, and the present embodiment describes the system control method provided by the present application by taking an application in a Windows system as an example.
It should be noted that, the system control method provided by the present application is executed by the cloud computer user terminal, and the cloud computer user terminal creates a process for the method to implement the relevant steps.
In specific implementation, a Process operated by a current cloud computer is subjected to traversal search according to a Process name by using a CreateToolhelp32Snapshot function, a Process32First function and a Process32Next function, so that a login Process Winlogon and a Process ID of the login Process Winlogon are obtained. And sending the acquired process ID to an OpenProcess function to open a login process Winlogon, and writing a dynamic link library into the login process to detect the operation of shutdown or restart of the user control system. It can be understood that the process is an operation performed before the user triggers the shutdown operation, and the process can be realized through a pre-generated script, or can be manually realized by a manager, and is more convenient and faster to realize through the script.
S11: and when the operation of the control system is detected, acquiring an operation instruction by using the dynamic link library, wherein the operation comprises shutdown and restart.
S12: and controlling the hardware driver to execute the operation instruction through the cleaning function.
It can be understood that, after the dynamic link library is injected into the login process, the process of obtaining the operation instruction through the dynamic link library may be to obtain a parameter of the execution function by using the dynamic link library, and determine the operation instruction corresponding to the parameter; for convenience of expression, the new shutdown function is named as a fast shutdown function in the application, and the fast shutdown function has the shutdown operation function of the original shutdown function and can also send the acquired operation instruction to the fast shutdown process, so that the fast shutdown process can perform corresponding operation on the cloud computer terminal.
In the implementation, when the computer system detects an operation of controlling the shutdown or the restart of the system, for example: and starting to execute a shutdown process after detecting that a user clicks a shutdown or restart button on a screen or detecting that the user sends a shutdown instruction through a command line. When the system starts to execute a shutdown process, the pre-generated quick shutdown function sends the acquired parameters to a quick shutdown process, and the quick shutdown process analyzes the acquired parameters to acquire an operation instruction. In order to reduce the shutdown time, the step of closing the application program is omitted, and after the rapid shutdown process obtains the operation instruction, the hardware driver of the cloud computer system is called by the cleaning function to execute the operation instruction so as to achieve rapid shutdown.
It can be understood that the cleaning function includes an NtShutdownSystem function, an ntinitiatepowermaction function, and the like, and is used for controlling the hardware drive of the cloud computer to implement fast shutdown. When the cleaning function is called, firstly, a hardware drive is informed to store kernel data, cache information of a registry and a file in a cache queue is refreshed on a disk, and unsaved application data are discarded; and then resetting the hardware drive and cutting off the power supply of the hardware equipment so as to skip the waiting stage to realize quick shutdown.
It should be noted that, since the cloud computer does not have a storage device such as a disk, the clean-up function cannot store kernel data and cache data. In order to meet the special requirement of a user for storing data, kernel data, cache data, files and the like can be packaged into a data packet form, and the data packet is sent to a remote server and stored in a special storage space of the user. When the user uses the cloud computer again, the cloud computer suitable for the user can be quickly created only by downloading data from the remote server.
It can be understood that, in the process of controlling the hardware driver to shut down or in the process of sending the data packet to the remote server, the cloud computer may not be shut down successfully due to the fact that the cloud computer is stuck, and when it is detected that the operation instruction is not successfully executed in the threshold time in the fast shutdown process, the system kernel program is called to control the execution of the operation instruction so as to cut off the power supply of the motherboard, thereby realizing the fast shutdown.
It should be noted that, in order to improve the security of the system and prevent the system from being automatically shut down due to external attack by using the fast shutdown process, the shutdown authority of the cleaning function may be cancelled, the cleaning function cannot control the hardware driver to shut down when the shutdown authority is not present, and the shutdown authority of the cleaning function is granted when the fast shutdown process is executed each time.
In order to improve the resource utilization efficiency of the cloud server, the cloud server can rapidly recover the computing resources after the cloud computer client is shut down, and the shutdown message can be sent to the scheduling system before the hardware drive is controlled to execute the operation instruction through the cleaning function, so that the speed of the scheduling system for recovering the computing resources is improved.
In this embodiment, a cloud computer control method is provided, and the method includes: and acquiring a login process of the system, and writing a dynamic link library into the login process to acquire an operation instruction sent to the system by a user. And when the operation of the control system is detected, acquiring an operation instruction by using the dynamic link library, and controlling the hardware drive to execute the operation instruction by using the cleaning function. And directly calling a cleaning function to execute an operation instruction, and skipping the steps of saving a closing process and saving a file, thereby improving the system shutdown speed. Therefore, by adopting the system control method provided by the application, the shutdown and restart speeds of the cloud computer can be improved, and the cloud host can conveniently recover the computing resources.
In specific implementation, because the actual computing capacity of the cloud computer operation end used by a client cannot be obtained, in the process of controlling hardware-driven shutdown by using a cleaning function, shutdown failure may be caused by the fact that an acquisition system request is blocked due to overlarge workload; or in the process of sending the data packet to the remote server, the cloud computer fails to be powered off due to data transmission failure caused by network disconnection of the cloud computer.
To solve this problem, on the basis of the above embodiment, after the step of controlling the hardware driver to execute the operation instruction by the cleaning function, the method further includes:
judging whether the operation instruction is successfully executed within the threshold time;
if the operation instruction is not successfully executed, calling a system kernel program to control and execute the operation instruction.
It is understood that the threshold time mentioned in this embodiment may be 10s, 20s, etc., may be a default time of the system, or may be set by the user, and is not limited herein.
In specific implementation, if the rapid shutdown process does not successfully execute the operation instruction within the threshold time, a system kernel HalReturn ToFirmware function is called, the power of a mainboard and other hardware equipment is cut off, and the computer is forced to be shut down.
In this embodiment, when the fast shutdown process fails to successfully execute the operation instruction within the threshold time, the system kernel program is called to execute the power-off operation, so as to implement fast shutdown or restart, and improve the stability and reliability of the system control method.
In order to improve the safety of the system and prevent the system from being automatically shut down due to external attack on the cleaning function, the shutdown authority of the cleaning function can be cancelled, and the shutdown authority of the cleaning function is granted when the cleaning function is called by the rapid shutdown process every time.
On the basis of the above embodiment, before the step of controlling the hardware driver to execute the operation instruction by the cleaning function, the method further includes:
and granting the cleaning function shutdown authority.
In specific implementation, the method for granting the shutdown permission to the cleaning function includes directly increasing the permission to the cleaning function so that the cleaning function can control the hardware drive to realize the shutdown task, and also granting the fast shutdown process so that the cleaning function shutdown permission is indirectly granted so that the cleaning function can control the hardware drive to realize the shutdown task when being called by the fast shutdown process.
In order to further improve the security of the system and prevent the cleaning function from being called by different processes, the latter scheme is selected in the embodiment. The system calls a ZwOpenProcessTokenEx function to open a Token handle of the rapid SHUTDOWN process, and then calls ZwAdjustprivilegeToken to grant SE _ SHUTDOWN _ PRIVILEGE authority to the handle of the current process, namely the SHUTDOWN authority. And after the fast shutdown process acquires the shutdown authority, calling a cleaning function (such as an NtShutdownSystemfunction) to control the cloud computer to be shut down or restarted.
In the embodiment, the shutdown authority of the cleaning function is temporarily granted during calling, so that the safety of the cloud computer is improved.
Files and user data do not need to be stored in scenes such as internet bars, but with the development of cloud technology, cloud technology services are applied in more and more scenes, such as: a company office scene, etc. In these scenarios, the user stores the files used by the user and the data generated during the use, so as to facilitate the subsequent work.
In order to solve this problem, on the basis of the above embodiment, before the step of controlling the hardware driver to execute the operation instruction by the cleaning function, the method further includes:
generating a data packet comprising kernel data and a cache file of the system;
and sending the data packet to a server.
In specific implementation, in the specific implementation, the file and the kernel data generated during the operation of the cloud computer are stored in corresponding folders, and the process of collecting the file and the kernel data may be as follows: copying files and kernel data at intervals of a preset time period; or collecting file and kernel data before executing shutdown or restart instructions. The second scheme is selected in this example. In addition, the user can select files to be saved and the like by himself and upload the files to the remote server.
In transmitting a file and kernel data to a remote server via a network, in order to reliably and accurately transmit the file and kernel data to a destination and efficiently utilize transmission resources (transmission devices and transmission lines), the file and kernel data are packaged in advance as a packet.
Common serial port encapsulation protocols include: high-level Data Link Control (HDLC) protocol, Point-to-Point (ppp) protocol, and frame-relay (FR) protocol. In the OSI7 layer network reference model, each layer of the model is primarily responsible for communicating with peer layers on other machines. When data encapsulation is carried out, the data with encapsulation is encapsulated in a group of protocol head and tail, the process is realized in a protocol data unit, wherein each layer of the model is composed of the protocol head, the protocol tail and the data encapsulation of the layer.
In order to ensure the transmission accuracy and enable the remote server to store the log file to a correct position, the name of a cloud computer or a user, the generation time of the file and kernel data and some bytes for error correction need to be added to the transmitted data packet, and in order to improve the safety and reliability of the data transmission process, the data packet can be encrypted.
In the embodiment, the data packet containing the kernel data and the cache file of the system is sent to the remote server, so that a user can store the required file and the kernel data, the subsequent use is convenient, and the application range of the system control method is expanded.
As a preferred embodiment, the obtaining the operation instruction by using the dynamic link library includes:
acquiring an execution function for executing an operation instruction in a login process;
generating a quick shutdown function on the basis of executing the function by utilizing the dynamic link library;
and determining an operation instruction according to the parameters of the quick shutdown function.
In the embodiment, the fast shutdown function is generated on the basis of executing the function by using the dynamic link library, so that the fast shutdown function is called when the cloud computer executes a shutdown or restart instruction, the condition that the operation instruction is failed to be acquired is prevented, and the stability and the reliability of the system control method are improved.
As a preferred embodiment, the process of obtaining the login of the system includes:
and acquiring the login process and the process ID of the login process in a traversing mode.
In a specific implementation, a Process search function (for example, a CreateToolhelp32Snapshot function, a Process32First function, and a Process32Next function) is used for performing traversal search on the Process information of the current host, and the Process name is compared to obtain the login Process winlogo and the Process ID of the login Process, so that the dynamic link library is conveniently injected into the login Process.
In a specific implementation, after the cloud computer is turned off, the cloud server needs to quickly recover the computing resources occupied by the cloud computer. In order to improve the resource utilization efficiency of the cloud server, on the basis of the foregoing embodiment, before the step of controlling the hardware driver to execute the operation instruction by the cleaning function if the operation is shutdown, the method further includes:
and sending the shutdown message to the scheduling system to improve the speed of the scheduling system for recovering the computing resources.
