Description

Method and computer device for setting attribute parameters of private image

technical field

The present application relates to the field of IT technology, and in particular, to a method and a computer device for setting attribute parameters of a private image in the field of public cloud technology.

Background technique

Virtualization technology is one of the key technologies in the field of cloud computing. It can virtualize the physical resources of a physical machine into multiple virtual machines (Virtual Machines, VMs). The physical resources are provided to each virtual machine by the virtualization platform in the form of a virtual resource pool. , different virtual machines can be assigned to different users, and physical resources are shared among virtual machines.

A virtual machine can be regarded as a complete computer system with complete hardware system functions simulated by software and running in a completely isolated environment. A virtual machine image is a cloud server template that includes software and necessary configurations. A virtual machine image contains at least an operating system, and may also contain application software such as database software.

In the field of public cloud technology, virtual machine images can be divided into two types: public images and private images. The public image is the default image provided by the system. It is the public basic image of the standard operating system officially provided by the cloud platform and is visible to all users. Private images are images created by users. They are personal images created based on cloud server or system disk backups, and are only visible to users themselves. Private images can include standard operating systems, pre-installed public application environments, and users' private applications. In specific applications, users can apply for an elastic cloud server using a public image or a private image, or create a private image from an existing cloud server.

In the public cloud scenario, the public cloud platform generates a private image through cloning or image import, and uses the private image to create a virtual machine and assign it to users. During the process of creating a virtual machine, or when a user imports his own private image through the public cloud platform, the user cannot configure the property parameters of the private image in advance, such as setting the 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.

Since the attribute parameters of the virtual machine cannot be configured in advance, the existing technology cannot meet the individual requirements of users in actual services in the field of public cloud technology, such as different security requirements of users in different production environments.

According to the difference or change of the functions of each part of the system, the hardware components of the computer device can be added or deleted. , so as to match the function of each part of the system.

During the process of using the virtual machine, the user can manually modify the registry key to modify the attribute parameters of the virtual machine. Taking the user modifying the default login password of the virtual machine as an example, the user can perform the following operations:

1) Manually expand "HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>Windows NT>CurrentVersion>Winlogon" to display all registry keys under "Winlogon", modify the value of "DefaultPassword", and modify "AutoAdminLogon" to 1;

2) Manually expand "HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>Windows>CurrentVersion>Run" to display all registry keys under "Run", double-click "(Default)" to pop up a dialog box and enter "C:\setpass" in the value data item .vbs".

Through the above operations, the user manually configures the default login password of the virtual machine, and can use the virtual machine as an image template to create other new virtual machines, so as to use the customized login password in the newly created virtual machine. Of course, similarly, the user can also modify the values of the corresponding attribute parameters by finding the registry entries corresponding to other attribute parameters of the virtual machine.

In the specific implementation process, the user can also modify the attribute information of the private image such as the virtual machine login password through a script program without manual operation; thus, after using the virtual machine as a private image to create a new virtual machine, the user can Log in to the newly created virtual machine using the set login password. The embodiment of modifying the virtual machine login password of the private image will be described in detail below with reference to FIG. 3 .

Step 301: The computer device obtains the path of the system password file and the registry file in the private image.

In the implementation of step 301, the computer device may first identify the operating system type on which the private image is mounted according to the directory where the private image is mounted, that is, "$rootPath". If the mount directory is "$rootPath/Windows/", it means that the virtual machine uses the Windows system; if the mount directory is "$rootPath/root/", it means that the virtual machine uses the Linux operating system.

Taking the Windows system as an example, the system password file path is "$rootPath/Windows/System32/config/SAM", and the registry file path is "$rootPath/Windows/System32/config/SOFTWARE". For the convenience of description, "Windows/System32/config/" in this application may be represented by "$configPath/", and "Windows/System32/config/SOFTWARE" may be represented by "$systemSoftwarePath".

Step 302: The computer device first backs up the system password file, and then performs a password clearing operation on the system password file.

Taking the Windows system as an example, the computer device first backs up the system password file in the "$rootPath/Windows/System32/config/" directory, such as the SAM file, and then uses the chntpw operation to clear the password of the Administrator user in the SAM file. The following is an example pseudocode for implementing step 302:

cp -f $rootPath/$configPath/SAM$rootPath/$configPath/SAM_BAK

chntpw -u Administrator $rootPath/$configPath/SAM<<EOF

>1

>y

>EOF

It should be noted that in step 302, the computer device backs up the system password file for security reasons, and once the operation of modifying the virtual machine login password of the private image in this embodiment fails, the previous state can be restored. .

Step 303: The computer device modifies the virtual machine automatic login registry and the virtual machine automatic startup script registry in the private image.

Taking the Windows system as an example, the example of the virtual machine automatically logging in to the registry 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 script registry that automatically starts the virtual machine when the Windows system is started is as follows:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]

"InitScript"="c:\\setpass.vbs"

In step 303, the computer device can use the pseudocode of the following example to modify the automatic login registry of the virtual machine:

reged -I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/

ecs_scripts/winlogon.reg–C

In step 303, the computer device can use the following pseudocode to modify the registry of the virtual machine startup automatic startup script:

reged -I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/

ecs_scripts/runsetpass.reg–C

Step 304: The computer device modifies the shutdown event tracker registry in the private image, so that the virtual machine does not display a dialog box for shutdown event tracker after startup.

An example of closing the event tracker registry on 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 the shutdown event tracker registry using pseudocode of the following example:

reged -I$rootPath/$systemSoftwarePath HKEY_LOCAL_MACHINE\\SOFTWARE/opt/

ecs_scripts/reliability.reg–C

In step 304, by modifying the shutdown event tracking program registry in the private image, the impact 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 above step 302, the computer device may also detect the private image to determine whether the virtual machine login password of the private image has been modified. If the virtual machine login password of the private image has been modified, the computer device will not modify the virtual machine login password of the virtual machine; only if the virtual machine login password of the private image has not been modified, the computer Only then does the device execute the above-mentioned embodiment of modifying the login password of the virtual machine of the private image shown in FIG. 3 . For example, the computer device can use the reged command to export the registration key of the automatic running program in the SOFTWARE registry file to determine whether the login password of the virtual machine of the private image has been modified. If the registration key of the auto-run program contains both "setpass.vbs" and "InitScript", the private image of the virtual machine is a private image that has been configured with "InitScript"="C:\\setpass.vbs". The specific implementation pseudo-code example is as follows:

Using the above-mentioned embodiment shown in FIG. 3 of the present application, by executing the script program on the computer device, the user can modify the attribute parameters of the private image in an offline state, so as to meet the personalized needs of the user in the actual business. Different security requirements in the production environment improve the user experience.

For example, when a user creates a private image by cloning or imports his own private image through a public cloud platform, the user can directly complete the initial login password of the virtual machine when using the private image to create a virtual machine without manually configuring the property parameters of the private image. injection. Taking the Windows virtual machine under the public cloud platform based on XEN virtualization as an example, the user can customize the initial login password when creating a virtual machine through the public cloud interface, and the login password is sent to the virtual machine through the interface of the cloud computing management platform OpenStack. Management platform, the virtualization management platform mounts the image file of the Windows system disk on Domain0 on the computing node agent (Computing Node Agent, CNA), and identifies the directory where the SAM file and the SOFTWARE registry are located, the virtualization management platform Copy the startup script file setpass.vbs and the password configuration file passwd.inf to the mount directory of the private image (that is, the image file of the Windows system disk), that is, the root directory of the C drive of the Windows system, and the virtualization management platform Modify the attribute parameters of the image file of the Windows system disk mounted in the mount directory. In this way, after the virtual machine is started, it can trigger the execution of the boot auto-start script setpass.vbs, realize the setting of the property parameters of the private image such as the virtual machine login password, and then clean up the above-mentioned password configuration file passwd.inf and boot auto-start script setpass.vbs, And restore the registry to realize the cleaning of the startup script registry and the automatic login registry settings, so as to restore the on-site environment, restart the virtual machine, and present a clean virtual machine login window to the user.

On the other hand, in the scenario where the user uses a public cloud virtual machine, if the user forgets the virtual machine administrator password, the login password of the virtual machine can also be reset by the above-mentioned embodiment shown in FIG. 3 of the present application. The computer device first imports the user's private image to the public cloud platform through the image service management platform, and mounts the virtual machine's system image file as a temporary data disk on a pre-prepared temporary host before creating a virtual machine instance from this private image. . Still taking a Windows virtual machine as an example, you can prepare a temporary Linux virtual machine as the above temporary host for backup, and reset the login password of the virtual machine by performing the following operations:

1) Modify the security group rules of the Windows virtual machine, such as closing port 3389 of the "TCP" protocol item, to prevent other IP addresses from accessing the virtual machine;

2) close the Windows virtual machine, unload the system disk of the Windows virtual machine as the private image of the Windows virtual machine, and mount the system disk on the temporary Linux virtual machine prepared in advance as a temporary data disk;

3) Remotely log in to the temporary Linux virtual machine, and install the above-mentioned temporary data disk, such as a software package that supports the NTFS file system and a tool for modifying the Windows registry in the temporary data disk;

4) Execute the script for modifying the login password of the Windows virtual machine; clear the original login password of the Windows virtual machine;

5) Unload the temporary data disk of the temporary Linux virtual machine online, that is, the system disk of the original Windows virtual machine, and remount the temporary data disk, that is, the system disk of the Windows virtual machine, back on the original Windows virtual machine;

6) Open the original Windows virtual machine, and restore the security rules modified in 1) above, such as opening port 3389 of the "TCP" protocol item.

The above embodiments of the present application only take setting the login password of the virtual machine as an example, and other attribute parameters of the virtual machine can also be set in a similar manner. For example, the operation of setting the machine name and the IP address is added to the setpass.vbs script. The above embodiments of the present invention can also be used to configure the machine name and IP address information in the private image. details as follows:

1) Before using the private image to create a virtual machine, you can mount the private image to Domain0, and automatically log in through offline configuration at the bottom layer, write the boot-up automatic startup script into the registry, and at the same time according to the user's own settings One or a combination of attribute parameters such as virtual machine login password, machine name, and IP address is passed down through the OpenStack interface, and corresponding custom configuration files such as passwd.inf, network.inf, hostname.inf, etc. are generated; and these custom The configuration file is injected into the root directory of the Windows system, namely "$rootPath".

2) After the virtual machine starts automatic login, it triggers the execution of the automatic startup script setpass.vbs, and reads the custom configuration files passwd.inf, network.inf, hostname.inf, etc. to configure the virtual machine attribute parameters.

3) Delete the above custom configuration file and setpass.vbs script, and restore the registry.
