Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Example one
The embodiment of the application provides an updating method for a single mirror image push local terminal, which comprises the following steps S101 to S104:
and step S101, cutting and customizing the winPE mirror image based on the minimization system.
In the step, the minimization system only comprises a mainboard, a memory bank, a hard disk and a CPU, and the winPE mirror image is cut out according to the customization of the minimization system, so that the network consumption is saved when the operating system is started. In addition, images of win7, win10, etc. may also be replaced by Linux images.
And step S102, starting the operating system through the winPE mirror image.
Specifically, the winPE is an image clipped by the basic operating system, and starts the operating system based on the image to generate a virtual desktop, so that operations such as installing software and the like can be executed in the virtual desktop.
The difference between the step and the prior art is that the mirror image data needs to be read from the server through the network when the machine is started at present, and because some desktop programs, background programs and background services which are started automatically exist when Win7 and Win10 enter the desktop, the flow of more than 500M is needed when the Win7 is started, and the flow of more than 960M is needed when the Win10 is started. The customized and cut winPE image is only used for pushing the image, no redundant network traffic is consumed, and only 260M traffic is needed. Compared with win7 and win10, the method saves 2-3 times of flow data. The low traffic will result in lower network consumption and faster start-up. And the customized small mirror image only needs to read mirror image data for the first drive, and the subsequent startup is directly started from the local, so that the network consumption is 0.
And step S103, acquiring the primary mirror image file pushed by the server.
In this step, the server software runs on the server, and the master image file is also stored on the server. The master image file refers to a system file acquired from a server and used for creating a virtual desktop.
The push refers to that a client acquires a new operating system image from a server through a network, and is network data interaction between client software and server software.
The mirror image pushing specifically comprises the following steps:
firstly, after the version of the main image file of the server side (server) is updated, the client side (each client) is informed that the current system is updated.
And secondly, the client requests the updated data block index and the data size from the server.
And thirdly, the client requests a service list from the server.
And fourthly, the client requests corresponding data from the machines in the service list according to the data block index and writes the data into the local primary mirror image file.
And step five, finishing the mirror image pushing service after all the data requests are finished.
And step S104, operating the master image file to enter an operating system, receiving the update file pushed by the server, and updating the version of the master image file based on the update file to obtain the version-updated master image file.
In this step, the server issues a version update message to the virtual desktop, and simultaneously pushes the update file, and the terminal acquires the update file and updates the version of the master image file based on the update file.
In one embodiment, step S104 further includes: and running the updated master image file to start the operating system.
In this example, the primary image file is a new operating system image acquired by the client to the server through the network, and the virtual desktop can be used when the client restarts the operating system by using the primary image file after the primary image file is pushed.
Through the steps S101 to S104, the present application provides a technical solution of replacing images such as win7 and win10 with a win pe image or a Linux image, where some desktop programs, background programs, or background services that are bootable and self-bootable are provided when the win7 and win10 systems enter the desktop, and these all generate network data interaction with the server, so that a lot of redundant network traffic is increased. The small images of the winPE and the Linux customized in the scheme are only used for pushing the images, and redundant network flow consumption is avoided. The network consumption when the operating system is started through the small mirror image can be saved, and the system can be quickly accessed to push the mirror image. And the only work of the winPE and Linux images after the operating system is started is to push the main image to the local, and no strategy or desktop application program is executed, so that network resources and server resources are saved, the network resources can be maximally utilized by synchronous work, the pushing efficiency is improved, and the winPE and Linux images are automatically restarted to enter the corresponding system after being pushed.
Illustratively, fig. 1 is a flowchart of a PE update mode according to an embodiment of the present application, where as shown in fig. 1, a desktop of a client is virtualized, and a remote desktop is run by using a thin terminal, such as a winPE or Linux image, after entering the remote desktop, a synchronization program is started to interact with a server, and a synchronization program acquires image data from a server to a local terminal, so as to complete pushing and restarting to enter a corresponding image. The difference between this embodiment and the prior art is that winPE, Linux is custom tailored according to a minimization system, where minimization means that only the most basic components that enable clients to boot and interact with the server are installed in this example. The conventional win10 and win7 images are all installed with desktop programs, background programs or background services which are started automatically, network traffic is large in the process of starting an operating system due to network data interaction between the programs or the services and a service end, a small image customized by the minimized system only comprises necessary elements and a virtual disk drive required by starting equipment, corresponding system information is read from a server through the virtual disk drive and is directly written into a local hard disk, and therefore network resources are saved.
Example two
The embodiment of the application provides a background updating method for a multi-mirror image push local terminal, which comprises the following steps S201 to S204:
step S201, a primary mirror image file pushed by the server is acquired.
In one embodiment, acquiring the primary mirror image file pushed by the server comprises: establishing a network connection and sending a request, wherein the request is used for copying a master mirroring file of a required type of operating system; a master image file is received.
In this example, the operating system is started without a disk and the system file pushed by the server is received through the network. The operating system can be started by using the win7 and win10 images, and preferably, the embodiment starts the operating system by collecting the customized win PE image provided by the first embodiment, so that the network flow during diskless starting is reduced
Step S202, operating the main mirror image file to enter an operating system, and copying a secondary mirror image file in the local disk by the main mirror image file.
In this step, the primary mirror image file and the secondary mirror image file refer to two systems written in the local disk, and the two systems do not have primary and secondary points. In this example, the primary and secondary mirror image files may also be the first mirror image file and the second mirror image file; a current mirror image file and a backup mirror image file; an initial image file, a copy of an image file, etc.
Step S203, receiving the update file pushed by the server, and performing version update on the secondary mirror image file based on the update file to obtain a secondary mirror image file with an updated version.
The effect of the secondary image file here is: when the current operating system is the main image file and just receives the version updating message issued by the server, the auxiliary image file can be updated in the background, and the problem of poor desktop using effect can not be caused when the desktop is used in the main image file. It should be noted that there may be a plurality of sub-image files, and when updating in the background, a plurality of sub-image files may be updated simultaneously, or only one of the sub-image files may be updated, as long as the latest version of the image file can be entered after the restart, and the latest version of the image file is pushed to the main image file or other sub-image files in the background by using the disk read/write.
The background updating referred in the step means that the desktop does not need to write back data to the server when in use, but is updated in the local background, so that the problem that the normal use is influenced by network fluctuation does not exist.
Specifically, when the desktop in the conventional modes win7 and win10 is normally used, real-time network interaction with the server is required, data are written back to the server, a large amount of network data are read and written in the mirror image pushing process, and bandwidth is used to cause network fluctuation, operation blockage, delay and the like when the desktop is normally used, so that the desktop is poor in using effect.
In addition, the push storage of the mirror image data in the primary and secondary mirror image modes is safer, and even if the data is damaged in the push process, at least one mirror image can be ensured to be good, so that the starting of the local mirror image cannot be influenced; in the traditional mode, if data is damaged in the pushing process, a subsequent machine cannot be started normally, the machine must be restored to the previous restoration point, and the full-disk synchronization must be performed again seriously, so that the normal use of a user is influenced. Therefore, another technical point of the embodiment is to solve the problem that the subsequent machine cannot be started normally due to data damage in the data pushing process.
And step S204, restarting to enter the secondary mirror image file with the updated version, and differentially pushing the secondary mirror image file with the updated version to the primary mirror image file in the local disk.
In this step, the secondary mirroring file is pushed to the primary mirroring file in a background disk reading and writing manner, so that the primary mirroring file and the secondary mirroring file are both the latest versions. That is to say, in the update file push scenario of the multi-image file, the other image files except the current image file can be differentially updated in the background to obtain the image with the latest version, the image is restarted to enter the image with the latest version, and the current image before being restarted is differentially pushed, so that all the image files in the client are the latest version.
That is, when the current image is the primary image, the server pushes the new version to the secondary image, the secondary image is updated to the latest, the machine is restarted to enter the secondary image, the secondary image is differentially pushed to the primary image, and the primary image and the secondary image are both the latest version at the moment. Similarly, when the current mirror image is the secondary mirror image, the server pushes the new version to the primary mirror image, the primary mirror image is updated to be the latest, the machine is restarted to enter the primary mirror image, the primary mirror image is differentially pushed to the secondary mirror image, and the primary mirror image and the secondary mirror image are the latest version at the moment.
In step S204, the pushing of the updated file can be performed in the background by storing the primary and secondary images in the local terminal, so that the use of the current system is not affected, and the problem of poor desktop use effect of the current image in the image pushing process is effectively solved.
The difference between this embodiment and the prior art is that, referring to fig. 2, at least two mirror images are stored in the local terminal, and when a new version is released, the difference is pushed to other mirror image files that are not the current mirror image to perform background difference update. After the update is completed, the other image files are all the latest versions, the operating system is started through other image texts, and at the moment, the current version before restart is the old version, so that the image file of the latest version in the local disk can update the image file of the old version in a differential push mode. According to the method and the device, the image file can be updated and optimized, the latest version of the image file can be obtained during login at each time, the beneficial effect that the desktop is used cannot be influenced when the image file is updated is achieved, the updating steps can be saved through real-time response, and the desktop using experience of the user is accelerated and optimized.
EXAMPLE III
The embodiment of the application provides a response type updating method of a current online system, which comprises the following steps:
step S301, receiving an update file pushed by a server in a current system;
step S302, judging whether other systems except the current system exist in the local disk;
and step S303, if the judgment result is yes, updating the versions of other systems based on the updated file to obtain other systems with updated versions.
Specifically, in the first embodiment, a PE update mode is provided, which saves network resources by restarting a small mirror image, such as winPE, and in the second embodiment, a background update mode is provided, which realizes background update by differential push of a primary mirror image and a secondary mirror image. The embodiment of the application provides a PE updating mode applied to a single-system or multi-system updating scene and a background updating mode applied to the single-system or multi-system updating scene, and is applicable to single-system or multi-system difference. The existing scheme must enter a single system to confirm whether an update is required or not in the single system. Whether the selected system needs to be updated or not is confirmed in multiple systems, namely, no matter a single system or multiple systems, the existing scheme needs to enter the system first to judge whether the system is updated or not, then the mirror image is pushed, and the latest system is restarted after the pushing is finished. Therefore, the present disclosure provides a scenario for operating the PE update mode and the background update mode, and the update procedure of a single system or multiple systems is described below with reference to system a1, system B1, system C1, system a2, system B2, and system C2.
1. Application of PE update mode
(1) Multi-system
The multi-system comprises a system A1, a system B1 and a system C1, after the system A1 is started, a client receives version update notifications of the system B1 and the system C1, and when the client judges that the image needing to be updated does not have the system A1, the client pushes an update file of the B1 image, and pushes the update file of the system C1 after pushing is finished, wherein the system B1 and the system C1 in the multi-system are the latest versions. That is, the technical effect is achieved that other systems except the current system can be updated in the background without entering the system and then confirming whether the update is needed.
(2) Single system
The single system is a system A1, when the system A1 is started, the client is restarted and enters a winPE mirror image pushing system A1 to update files after receiving a version update notice of the system A1, and the client is restarted and enters the system A1 of the latest version after pushing is finished. Namely, the technical effect of saving network resources by winPE mirror image pushing under a single system is realized.
2. Application of background update mode
(1) Multi-system
The multi-system comprises a system A2, a system B2 and a system C2, after the system A2 is started, a client receives version update notifications of the system A2, the system B2 and the system C2, starts to push update files of a main image of the A2 to a secondary image of the A2, pushes update files of a main image of the B2 to a secondary image of the B2 after pushing is completed, and pushes update files of a main image of the C2 after pushing is completed, wherein the system A2, the system B2 and the system C2 in the multi-system are latest versions at the moment. Namely, the technical effects that each system can be updated in the background, the system can be ensured to be the latest version when entering the system next time, and whether the update is needed or not is confirmed after entering the system are achieved.
(2) Single system
The single system is a system A2, the version update notification of the system A2 is received after the system A2 is started, the update file of the main image of the A1 is pushed to the auxiliary image of the A1, the auxiliary image of the A1 is restarted after the pushing is finished, and the update of the main image of the A1 is finished through the disk difference pushing.
That is to say, in the scheme, when the new version is released, the server notifies the local terminal, and in the background updating mode, no matter in a single system or multiple systems, the local terminal can perform differentiated updating based on the released update file. The PE updating mode can perform different updating processing according to a single system and multiple systems. When the system is judged to be a single system, the PE updating mode can directly enter the PE mirror image to start updating next time, and when the system is judged to be a multi-system, the current starting system can be excluded, and the other systems can start differential updating.
