Description
Technical Field
The application relates to the technical field of IT, in particular to a setting method of attribute parameters of a private image in the technical field of public cloud and computer equipment.
Background
The virtualization technology is one of key technologies in the field of cloud computing, and can virtualize physical resources of a physical Machine into a plurality of Virtual Machines (VMs), the physical resources are provided to each VM by a virtualization platform in the form of a Virtual resource pool, different VMs can be allocated to different users, and the VMs share the physical resources.

The virtual machine image is a cloud server template containing software and necessary configurations. The virtual machine image contains at least an operating system and may also contain application software such as database software.
In the technical field of public cloud, virtual machine images can be divided into public images and private images. The public image is a default image provided by the system, is a public basic image of a standard operating system officially provided by the cloud platform and is visible to all users. The private mirror image is a mirror image created by the user, is a personal mirror image created based on a cloud server or system disk backup, and is only visible to the user; the private image may include a standard operating system, a pre-installed public application environment, and a user's private application, among others. In a specific application, a user can use a public mirror image or a private mirror image to apply for an elastic cloud server, and can also create the private mirror image through an existing cloud server.

In the process of creating a virtual machine or in the process of importing the private image of a user through a public cloud platform, the user cannot configure attribute parameters of the private image in advance, such as setting an original password of the private image. If the user forgets the original password of the private image, the user cannot log in to the virtual machine created using the private image.
Due to the fact that the attribute parameters of the virtual machine cannot be configured in advance, the prior art cannot meet individual requirements of users in actual services in the field of public cloud technologies, such as requirements of different safety of the users in different production environments.

The embodiment of the present application does not limit the type of the computer device 200.
It should be noted that the computer device 200 shown in fig. 2 only shows a possible hardware implementation manner of each part in the cloud service system, and according to the difference or change of the functions of each part of the system, hardware components of the computer device may be added or deleted so as to match the functions of each part of the system.
During use of the virtual machine by a user, the user may manually modify the registry key to modify the attribute parameters of the virtual machine. Taking the example that the user modifies the default login password of the virtual machine, the user may perform the following operations:
1) manually expanding 'HKEY _ LOCAL _ MACHINE > SOFTWARE > Microsoft > Windows NT > Currentversion > Windoon' to display all registry entries under 'Windoon', modifying the value of 'DefaultPassionword' and modifying 'AutoAdminLogon' to 1;
2) "HKEY _ LOCAL _ MACHINE > SOFTWARE > Microsoft > Windows > Currentversion > Run" is manually expanded to display all registry entries under "Run", and "C: \ setpass. vbs" is entered in the numerical data item after double clicking "(Default)" pop-up dialog.
Through the above operations, the user configures the default login password of the virtual machine manually, and can create other new virtual machines by using the virtual machine as a mirror image template, so that the user-defined login password is used in the newly created virtual machine. Of course, similarly, the user may also modify the value of the corresponding attribute parameter by finding the registry key corresponding to the other attribute parameters of the virtual machine.
In the specific implementation process, the user can modify the attribute information of the private image, such as a login password of the virtual machine, through the script program without manual operation; therefore, after a new virtual machine is created by using the virtual machine as a private image, a user can log in the newly created virtual machine by using the set login password. An embodiment of modifying the private image's virtual machine login password is described in detail below in conjunction with fig. 3.
Step 301: the computer device obtains a system password file and a registry file path in the private image.
In the implementation of step 301, the computer device may first identify the operating system type of the mounted private image from the directory of the mounted private image, i.e., "$ rootPath". If the mount directory is "$ rootPath/Windows/", it indicates that the virtual machine uses a Windows system; if the mount directory is "$ rootPath/root/", it indicates that the virtual machine uses a Linux operating system.
Taking a Windows System as an example, the System password file path is "$ rootPath/Windows/System32/config/SAM", and the registry file path is "$ rootPath/Windows/System 32/config/SOFTWARE". For convenience of description, the term "Windows/System 32/config/" in this application may be denoted by "$ configPath/" and "Windows/System 32/config/SOFTWARE" may be denoted by "$ systemShowWaepath".
Step 302: the computer equipment backups the system password file and then executes password clearing operation on the system password file.
Specifically, taking a Windows System as an example, a computer device first backs up a System password file such as an SAM file under "$ rootPath/Windows/System32/config/" directory, and then clears the password of the SAM file administerrator user by using a chntpw operation. Example pseudo code to implement step 302 is as follows:
cp-f$rootPath/$configPath/SAM$rootPath/$configPath/SAM_BAK
chntpw-u Administrator$rootPath/$configPath/SAM<<EOF
>1
>y
>EOF
it should be noted that the reason why the computer device backs up the system password file in step 302 is for security, and once the operation of modifying the virtual machine login password of the private image is unsuccessful in this embodiment, the computer device may also restore to the previous state. .
Step 303: the computer equipment modifies the automatic login registry of the virtual machine and the automatic startup script registry of the virtual machine when the virtual machine is started up in the private mirror image.
Taking the Windows system as an example, an example of the automatic login registry of the virtual machine is as follows:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon]
"AutoAdminLogon"＝"1"
"DefaultUserName"＝"Administrator"
"DefaultPassword"＝""
an example of the virtual machine boot auto-start script registry, which takes the Windows system as an example, is as follows:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"InitScript"＝"c:\\setpass.vbs"
the computer device may modify the virtual machine auto-login registry in step 303 using pseudo-code as exemplified by:
reged-I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/
ecs_scripts/winlogon.reg–C
in this step 303, the computer device may modify the virtual machine boot auto-start script registry using pseudo code as an example:
reged-I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/
ecs_scripts/runsetpass.reg–C
step 304: the computer device modifies a close event tracker registry in the private image such that the virtual machine does not display a dialog to close the event tracker after startup.
An example of a close event tracker registry, such as a Windows system, is as follows:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Reliability]
"ShutdownReasonOn"＝dword:00000000
in step 304, the computer device may modify a close event tracker registry using pseudo code as exemplified below:
reged-I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/
ecs_scripts/reliability.reg–C
in step 304, the closing event tracker registry in the private image is modified, so that the influence on the automatic login process of the virtual machine can be reduced, and the user experience can be improved.
It should be noted that, before the step 302, the computer device may further detect the private image, and determine whether the virtual machine login password of the private image has been modified. If the virtual machine login password of the private mirror image is modified, the computer equipment does not modify the virtual machine login password of the virtual machine; the computer device executes the embodiment of modifying the private image's virtual machine login password shown in fig. 3 described above only if the private image's virtual machine login password has not been modified. For example, the computer device may determine whether the virtual machine login password of the private image has been modified by exporting the autorun program registration key in the softward registry file using the retrieved command. If the auto-run program registry contains both "setpass. vbs" and "InitScript", the private image of the virtual machine is the private image that has been configured with "InitScript" ═ C: \ \ setpass. vbs ". The specific implementation pseudo code example is as follows:
by using the above embodiment shown in fig. 3 of the present application, through executing the script program by the computer device, the user can modify the attribute parameters of the private image in the offline state, so that the personalized requirements of the user in the actual service, such as the requirements of the user on different safety in different production environments, can be met, and the user experience is improved.
For example, when a user creates a private image in a clone mode or the user imports the private image of the user through a public cloud platform, the user can directly complete the injection of the initial login password of the virtual machine when the private image is used for creating the virtual machine without manually configuring the attribute parameters of the private image. Taking a Windows virtual machine under a public cloud platform based on XEN virtualization as an example, when a user creates the virtual machine through a public cloud interface, the initial login password can be customized, the login password is sent to a virtualization management platform through an interface of an OpenStack of the cloud Computing management platform, the virtualization management platform mounts a mirror image file of a Windows system disk on don 0 on a Computing Node Agent (CNA) and identifies a directory where an SAM file and a SOFTWARE mail registry are located, the virtualization management platform copies a startup script file setpass.vbs and a password configuration file passswjnf to a mount directory of a private mirror image (i.e., a mirror image file of the Windows system disk), i.e., a C-disk directory of the Windows system, and modifies attribute parameters of the mirror image file of the Windows system disk mounted under the mount directory. Therefore, after the virtual machine is started, the startup automatic startup script setpass.vbs can be triggered and executed, the setting of attribute parameters of the private image, such as the login password of the virtual machine, is realized, then the password configuration file passswinf and the startup automatic startup script setpass.vbs are cleaned, and the registry is restored to realize the cleaning of the startup script registry and the automatic login registry setting, so that the field environment is recovered, the virtual machine is restarted, and a clean virtual machine login window is presented to a user.
On the other hand, in a scenario where the user uses the public cloud virtual machine, if the user forgets the password of the virtual machine administrator, the login password of the virtual machine may be reset through the foregoing embodiment shown in fig. 3 of the present application. The computer equipment firstly leads the private image of a user into the public cloud platform through the image service management platform, and before the private image is used for creating the virtual machine instance, the system image file of the virtual machine is used as a temporary data disc to be mounted on a temporary host prepared in advance. Still taking the Windows virtual machine as an example, the user may first prepare a temporary Linux virtual machine as the temporary host for standby, and reset the login password of the virtual machine by the following operations:
1) modifying security group rules of the Windows virtual machine, such as closing 3389 ports of the TCP protocol items to prevent other IP addresses from accessing the virtual machine;
2) closing the Windows virtual machine, unloading a system disk of the Windows virtual machine as a private mirror image of the Windows virtual machine, and mounting the system disk as a temporary data disk onto a temporary Linux virtual machine prepared in advance;
3) remotely logging in the temporary Linux virtual machine, and installing the mounted temporary data disk, such as a software package supporting an NTFS (New technology File System) file system in the temporary data disk and a tool for modifying a windows registry;
4) executing a script for modifying the login password of the Windows virtual machine; clearing an original login password of the Windows virtual machine;
5) unloading a temporary data disk of the temporary Linux virtual machine, namely a system disk of the original Windows virtual machine, on line, and re-mounting the temporary data disk, namely the system disk of the Windows virtual machine, back to the original Windows virtual machine;
6) opening the original Windows virtual machine and recovering the modified security rules in 1) above, such as opening 3389 port of the "TCP" protocol item.
In the above embodiments of the present application, only the login password of the virtual machine is set as an example, and other attribute parameters of the virtual machine may also be set in a similar manner. Vbs script is added with operations for setting machine name and IP address, for example, the above-described embodiments of the present invention may also be used to configure machine name, IP address information, etc. in a private image. The method comprises the following specific steps:
1) before a private mirror image is used for creating a virtual machine, the private mirror image can be mounted on a Domain0, the private mirror image automatically logs in a bottom layer in an off-line configuration mode, a startup automatic start script is written in a registry, and meanwhile, a corresponding custom configuration file such as passcode, network name, hostname and inf is generated according to one or a combination of attribute parameters such as a virtual machine login password, a machine name and an IP address set by a user per se and transmitted through an interface of an OpenStack; and the custom configuration files are injected into the root directory of the Windows system, namely, "$ rootPath".
2) After the virtual machine starts automatic login, a startup automatic startup script setpass.vbs is triggered to be executed, and custom configuration files passsd.inf, network.inf, hostname.inf and the like are read from the startup automatic startup script setpass.vbs to configure the attribute parameters of the virtual machine.
3) Deleting the self-defined configuration file and the setpass.
As shown in fig. 4, which is a schematic structural diagram of a computer device 400 provided in an embodiment of the present application, the computer device 400 includes an obtaining module 402 and a processing module 404. Wherein:
the obtaining module 402 is configured to obtain a registry file path in the private image;
the processing module 404 is configured to modify the automatic virtual machine login registry and the automatic virtual machine startup script registry in the private image according to the registry file path.
With the computer device shown in fig. 4, the user can set the attribute parameters of the private image without manual operation. Taking the modification of the virtual machine login password in the private image as an example, the processing module 404 may be implemented by using the method in the embodiment shown in fig. 3 of the present application. In a specific implementation, because there is a case that the operation of modifying the login password of the virtual machine of the private image is unsuccessful, for security, the obtaining module 402 in the computer device 400 of the present application may further be configured to obtain a system file of the virtual machine in the private image, and the processing module 404 is configured to back up the system file of the virtual machine and perform a clearing operation.
To reduce the impact on the automatic login process of the virtual machine and improve the user experience, the processing module 404 in the computer device 400 may also modify the close event tracker registry in the private image so that the virtual machine does not display the dialog box for closing the event tracker after being started.
The computer device 400 of the present application may further include a virtual machine creation module 406 for creating a virtual machine from the modified private image. Thus, when a user creates a virtual machine by using a private image created in a clone manner or importing a private image of the user through a public cloud platform, the user can directly complete setting of attribute parameters when creating the virtual machine, such as injection of an initial login password of the virtual machine, without manually configuring the attribute parameters of the private image by using the computer device 400 of the present application. After the attribute parameters are set, the field environment is recovered, the virtual machine is restarted, and a clean virtual machine login window is presented to the user, so that the user experience is improved.
Computer device 400 of the present application may also include a virtual machine control module 408. The virtual machine control module 408 is configured to mount a system disk of the virtual machine as a temporary data disk on the temporary host before the obtaining module 402 obtains the registry file path in the private image; further, the virtual machine control module 408 is further configured to, after the processing module 404 modifies the virtual machine automatic login registry and the virtual machine startup automatic startup script registry in the private image according to the registry file path, uninstall the temporary data disk on the temporary host, and mount the temporary data disk as a system disk on the virtual machine corresponding to the private image. The virtual machine control module 408 can also be configured to shut down the virtual machine corresponding to the private image.
In a scenario where a user uses a public cloud virtual machine, if the user forgets a password of a virtual machine administrator, through cooperation of the virtual machine control module 408, the computer device 400 may implement resetting of an attribute parameter of the virtual machine, such as a login password, through the foregoing embodiment shown in fig. 3 of the present application.
It should be noted that the computer 400 according to the above-mentioned embodiment of the present application may include at least one processor and at least one memory, and after the at least one processor executes the computer program stored in the at least one memory, the computer device 400 executes the method for setting the attribute parameters of the virtual machine according to the above-mentioned embodiment of the present application.
