Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

As shown in Figure 1, the present invention proposes a kind of method for operating system installation, it is characterized in that, comprises:

Step S1, obtaining the configuration information of the server to be installed, and formulating a configuration strategy according to the configuration information;

Step S2, formulating a virtual image structure based on the configuration strategy and the target operating system;

Step S3, installing an operating system for the server to be installed through the virtual image structure.

In the embodiment of the present invention, in step S1, the server to be installed refers to the server host that needs to install the operating system, that is, the physical machine, and the configuration information refers to the server's CPU, memory, hard disk structure, etc. configuration information that is closely related to the normal operation of the server . The configuration information of the server to be installed can be obtained through various means, such as obtaining the specific model, CPU, memory, hard disk or RAID card (Redundant Arrays of Independent Disks, independent disk array) and other hardware configuration information of the server to be installed from the corresponding management system; Formulating a configuration strategy based on the configuration information refers to determining the installation method or configuration strategy when installing the corresponding operating system through the collected model information of hardware such as CPU, memory, hard disk, or RAID card and network card. The configuration strategy refers to the installation steps that can normally complete the installation of the target operating system on the server to be installed or the solution that can install the corresponding operating system on the server to be installed, and refers to the execution process of the overall installation guide program for installing the target operating system. There are different configuration strategies for different servers to be installed and different target operating systems.

Specifically, the operating system is a management system that manages various hardware on the computer and provides hardware services for corresponding application programs. The essence of installing an operating system on a server or computer equipment is to install a management system on the server or computer equipment. Therefore, it is necessary to obtain the CPU, hard disk, RAID card, network card, motherboard information, etc. of the server to be installed, and further analyze whether the target operating system can directly support the direct operation of the server to be installed, that is, manage the hardware of the server to be installed. For example, if the server to be installed is an ARM platform server, when installing the Linux operating system, the Linux system kernel needs to be compiled according to the model of the ARM CPU, otherwise the Linux kernel cannot run; for example, the Windows7 system does not carry the Intel 7 The driver of the above-generation Core motherboard may cause the system to fail to install during the installation process.

Therefore, in some embodiments of the present invention, the present invention needs to acquire hard disk configuration information of the server to be installed, and formulate corresponding configuration policies according to the hardware configuration information. According to the hardware configuration of the server to be installed, the corresponding target operating system installation plan is formulated, including the execution process of installing the boot program, and the corresponding hardware driver required for installing the boot program.

In some embodiments of the present invention, the server to be installed may also be a virtual machine provided by a virtualization platform, such as a virtual machine created by tools such as VMware Workstation, Virtual Box, and Virtual PC. Compared with the physical machine, some hardware of the virtual machine server is provided by the virtual machine software, so for the virtualization platform, it is only necessary to obtain the corresponding virtual machine configuration information from the corresponding virtual machine software system.

In step S2, the virtual image structure is a structure proposed by the present invention for guiding the installation of a type of hardware configuration server and the corresponding target operating system. It should be noted that, in practice, the installation of the operating system on the computer can be done by means of a system image. The system image usually adopts the .iso file storage format (CD image file format). The optical drive reads the data on the optical disc and loads it into the computer to realize the installation of the corresponding operating system. However, the virtual image structure proposed by the present invention is not a system image with a size of several GB at every turn, that is, the virtual image of the present invention is not an image file in the format of .iso, but a hardware configuration information and target image based on the server to be installed. The data structure of the operating system includes three categories: operating system file information (version information of the target operating system, operating system file address), installation boot program information (installation boot program during system installation), driver information (according to The hardware configuration information of the server to be installed and the driver information of the corresponding hardware required in the installation process determined by the target operating system).

In this embodiment, according to the configuration strategy in step S1, it is determined whether the corresponding driver program needs to be loaded when the target operating system is installed on the server to be installed, and if the driver program is required, the corresponding driver program information is added to the virtual image structure If you need to set some installation options during the operating system installation process, add the configuration parameters of the corresponding setting program to the installation boot program information part, and add the target operating system information to the virtual image structure. OS file information section.

Further, in some embodiments of the present invention, the file address of the driver loaded when installing the target operating system and the corresponding MD5 value are added to the driver information part of the virtual image structure; the corresponding installation boot program file and The file address of the configuration file and the corresponding MD5 value are added to the installation boot program information part corresponding to the virtual image structure; the operating system file address of the target operating system and the corresponding MD5 value are added to the operating system file information part of the virtual image structure .

In step S3, the content of the corresponding part in the virtual image structure is sent to the server to be installed and the installation boot program is executed to install the operating system files in the virtual image structure. That is, according to the .iso file format, the corresponding installation boot program file, configuration file, driver program file, and operating system file in the virtual image structure are sent to the server to be installed to load the installation boot program file to execute the installation of the target operating system.

In some embodiments of the present invention, obtaining the configuration information of the server to be installed includes:

Obtain the configuration information of the server to be installed through the memory operating system.

In this embodiment, the configuration information of the server to be installed is acquired by means of an in-memory operating system. For example, to obtain it in the form of LiveCD, specifically, send the LiveCD containing the query server hardware configuration program to the server to be installed through the out-of-band BMC (Baseboard Management Controller). After the LiveCD image is loaded into the memory, run the query server hardware configuration The program obtains information such as the CPU model, memory, hard disk or RAID card model, network card model, mounted PCIE device, and startup mode (UEFI/MBR) of the server to be installed. Feedback the obtained hardware configuration information through BMC. Further, after receiving the hardware configuration information of the server to be installed fed back by the BMC, a configuration strategy can be formulated according to the configuration information.

In some implementations of the present invention, obtaining the configuration information of the server to be installed, and formulating a configuration strategy according to the configuration information includes:

Obtaining the storage structure of the server to be installed, and judging whether the storage structure supports drive-free installation of the target operating system;

In response to the storage structure not supporting drive-free installation of the target operating system, configuring the storage structure according to the installation requirements of the target operating system, and adding the driver information of the storage structure to the configuration policy.

In this embodiment, it is also necessary to judge the storage structure of the server to be installed. The storage structure refers to the connection mode of the storage device (hard disk) on the server to be installed, which can be roughly divided into two types. The other way to form a RAID is to directly connect the hard disk to the server motherboard. The first method requires the installation of the bootloader to support the RIAD card. That is, if the target operating system does not support it, the installation will fail because the corresponding disk cannot be selected when entering the corresponding step of installing the bootloader. Therefore, it is necessary to obtain the storage structure of the installation server and determine whether the installation boot program can use the storage device on the server to be installed to install the operating system without a driver. If the storage structure on the server is not supported by the installation boot program, you need to add the corresponding driver information to the configuration policy, and further add the driver information to the virtual mirror structure when generating the virtual mirror structure according to the configuration policy.

In addition, the storage structure not supported by the installation boot program is mainly because the RAID card used is not supported by the installation boot program, and because the RIAD card does not have any configuration when the system is not installed on the server, it is necessary to specify the RAID of the server to be installed as needed mode and allocate the corresponding disk space for storing data and/or installing the target operating system.

In some embodiments of the present invention, formulating a virtual image structure based on the configuration strategy and the target operating system includes:

Developing the installation guide program information of the target operating system based on the configuration policy and the target operating system, and adding the installation guide program information to the virtual image structure.

In this embodiment, if the configuration policy formulated according to the hardware configuration of the server to be installed includes the driver-related information of the corresponding hardware, it means that the installation boot program of the target operating system does not support the relevant hardware of the server to be installed, and the relevant hardware's Drivers are added to the installation bootloader.

Specifically, taking the Windows operating system as an example, the Windows operating system needs to use the boot.vim file in the Windows image when installing the Windows operating system. The boot.vim file is essentially an image file of a memory operating system provided by Microsoft. The file is about 200MB included in the Windows Files required for installation. Therefore, in general, if a hardware configuration on the server to be installed is not supported by Microsoft's installation boot program, you need to add the hardware driver to the installation boot program, that is, the boot.vim file and then regenerate the Driven boot.vim file.

In some embodiments of the present invention, when formulating the installation guide program information of the target operating system based on the configuration strategy and the target operating system, the original boot.vim is now decompressed, and then the driver file is stored in the decompressed In the directory for storing custom programs, repackage the decompressed boot folder containing the driver file into a boot.vim file. Further add the file address and related information of the regenerated boot.vim (the driver information contained in the boot.vim file, the version information of the operating system that can be used to boot and install, and the MD5 value of the repackaged file, etc.) to In the virtual image structure.

In some embodiments of the present invention, the driver is no longer directly added to the boot.vim, but is divided into blocks according to the contents of the boot.vim file. The boot.vim file is carefully distinguished when it is read in binary, that is, to distinguish which is the image file area of the Windows installation boot program (memory operating system), and which is the data area that can be customized by the user to store the driver. Further add the data address range of the above-mentioned area where the boot program is installed and the area where the driver can be customized by the user to store the driver into the virtual image structure.

Specifically, if the original size of the boot.vim file is 200MB, and the driver required by the server to be installed is 30MB, if the driver is added to boot.vim, the driver is directly written in the form of an append In boot.vim, in the virtual mirror structure, boot.vim and the corresponding driver information and addresses are saved in sequence, indicating that the boot program and driver are installed in a continuous manner in the boot.vim mirror data save. If the driver is stored in the 190MB data range in boot.vim, and the last 10MB data is other data in boot.vim, you need to add the address range of the embedded data of the driver to the virtual image structure. It can be understood that 0-190MB is the first part of the original data of boot.vim, then the driver of 30MB, and the last 10MB is another part of the original data of boot.vim. The above are just examples for easy understanding. For detailed configuration rules, please refer to the format reference document "Windows Image File Format" about boot.vim provided by Microsoft.

Preferably, in some embodiments of the present invention, the installation boot program is no longer considered in the packaging form of boot.vim, but it is decompressed into (according to the "Windows Image File Format" format specification) multiple files or file directories , and add the address of each file (all files under one or more directories as a whole) and the corresponding verification information, that is, the MD5 value, to the corresponding virtual image structure. When it is necessary to add a corresponding driver therein, the file address and MD5 of the driver are directly added to the corresponding position of the virtual image structure according to the decompressed file relationship. That is to say, the entire installer part appears in the directory structure after decompression of the boot.vim after encapsulating the corresponding driver in the above-mentioned embodiment in the entire virtual mirror structure, that is, no longer pair boot.vim (referring to the installation) according to different drivers. The integral part of the boot program) is packaged into a file, but a structure (a part of the virtual mirror structure) about installing the boot program is "encapsulated" in the virtual mirror structure. It can be seen that when the hardware configuration of the server to be installed is different or the operating system to be installed is different, it is only necessary to update the address and MD5 value of the corresponding driver in the virtual image structure or the address and MD5 value of the operating system image. . There is no need to package or generate multiple boot.vim files according to different hardware conditions, which is time-consuming and wastes storage space to customize the installation boot program.

In some embodiments of the present invention, formulating a virtual image structure based on the configuration strategy and the target operating system includes:

Create an answer file template according to the target operating system, generate answer file information corresponding to the answer file template based on the configuration policy, and add the answer file information to the virtual image structure.

In this embodiment, the answer file is a configuration file that guides the installation boot program to install the operating system, and the answer file template is a general template according to the installation mode of different operating systems. Different types of operating systems have different answer file templates, such as Windows operation The system and the Linux system have different installation templates due to different bootloader installation methods, that is, different installation bootloaders correspond to different answer file templates.

Further, after determining the operating system to be installed on the server to be installed, configure the additional processing items required to install the boot program into the answer file template in the order of installation, and use the configured answer file template as the target operating system for the server to be installed The answer file, and read the content of the answer file as a character string and add it to the virtual image structure. When the boot program is installed to install the target operating system, the corresponding executable program is loaded or the corresponding operation is performed through the configuration steps on the answer file.

In some embodiments of the present invention, taking the Windows system as an example, if the operating system of the server to be installed needs to load the RAID card driver, the installed RAID card driver file information needs to be added to Autounattend.xml. In some cases, if the installation bootloader needs chipset driver support when installing the target operating system, it is also necessary to write the chipset driver support to Autounattend.xml. When the driver installation of multiple hardware devices is involved, it is necessary to add the driver installation sequence to Autounattend.xml according to the dependencies of the hardware devices. Finally, Autounattend.xml is read and loaded into the virtual image structure.

In some embodiments of the present invention, the creation of the answer file is also completed in the form of a non-file, that is, the bootloader parameter item is installed in the virtual image structure, and the installation bootloader parameter item is divided into two parts. The first part is the installation The driver options when the boot program installs the target operating system, that is, what information about the driver that needs to be mounted after the boot program (memory operating system) starts, and the target operation when the target operating system can be installed after the driver is mounted The operating options of the system, that is, the installed operating system version, the installation disk location of the target operating system, whether to format the disk, and other configuration parameters.

In addition, the second part includes the driver or some software configuration items to be loaded when the operating system loads the target operating system from the disk after the installation of the boot program is completed (that is, after the operating system in the image is copied to the disk and configured for booting). . For example, the driver installation options for all hardware devices of the server (it should be noted that the driver installation at this time is different from the previous installation of the boot program. The installation boot program is a simplified memory operating system, which needs to be Some drivers, and these drivers are loaded into the memory, and do not exist on the disk, so the installed drivers will disappear after power failure), after the target operating system is started from the disk, the corresponding driver is automatically installed to Improve the operating environment of the target operating system.

In this embodiment, the parameter options of the above two parts can be configured in the virtual image structure as required, and when an answer file needs to be generated, add the parameters in the installation boot program parameter item in the virtual image structure according to the answer file template Large answer file template to generate a corresponding answer file.

The installation guide program parameter items in the virtual image structure can be modified through the program or directly imported from some configuration files when needed, which is convenient for the staff to import in batches.

In some embodiments of the present invention, installing an operating system for the server to be installed through the virtual image structure includes:

Generate a target operating system image file according to the virtual image structure, and send the target operating system image file to an installation device, and install the target operating system image file on the server to be installed through the installation device.

In this embodiment, if the system image file is selected for installation, the target operating system image file in .iso format can be generated according to the information in the virtual image structure. The virtual image structure includes what is required for the installation of the target operating system: the installation boot program (memory operation repair), the relevant drivers required for the installation of the boot program, the target operating system image file, and the answer file. Therefore, according to the file address in the above information in the virtual image structure, the corresponding file is obtained and an .ios image file adapted to the hardware configuration of the server to be installed is generated according to the requirements of the ISO image format.

Further send the .iso image file to the installation device. The installation device refers to the device that can use the .iso file as the installation structure of the computer system. For example, if the CD is used as the medium, the system image file will be burned to the CD. The mount device installs the target operating system. In addition, if it is a device provided by a virtual CD-ROM drive, for example, the U disk is virtualized into a virtual CD-ROM drive, you only need to copy the generated .iso image file to the U disk.

Preferably, for the server field, the BMC can be used to implement the .iso image file of the target operating system installed on the virtual optical drive of the server to be installed.

In some embodiments of the present invention, installing an operating system for the server to be installed through the virtual image structure includes:

Obtain the corresponding target operating system installation file in the virtual image structure, and send the target operating system installation file to the installation device;

providing a virtual optical drive to the server to be installed through the installation device,

The target operating system installation file is loaded onto the server to be installed through the virtual optical drive, so as to install the target operating system.

In this embodiment, when the operating system is installed for the server to be installed through the virtual image structure, data in the virtual image structure may be sent to the device according to the .iso format specification based on the virtual image structure.

It should be noted that if the serial port line of the PC (the computer equipment that executes the program of the present invention) is connected to the server to be installed, and the virtual CD-ROM drive is provided through the PC, the PC obtains the corresponding address according to the virtual image structure. Install the boot program file, driver file, system image file and answer file, and provide data to the virtual CD-ROM according to the .iso format specification, and install the target operating system.

In some embodiments of the present invention, if the installation device is a BMC, and the BMC of the server to be installed is accessed through the network through a PC, and the BMC provides a virtual CD-ROM drive, that is, when the target operating system is installed in an out-of-band installation mode, After the PC obtains the above files in the virtual image structure, it sends the data stream to the BMC according to the .iso file format specification. After receiving the data, the BMC sends the data to the virtual CD-ROM provided by the BMC to the server to be installed in order of receipt. Install the target operating system by simulating a normal CD-ROM to read the .iso image file. There is no need to generate the corresponding image file in .iso format.

In some embodiments of the present invention, installing an operating system for the server to be installed through the virtual image structure includes:

Send the virtual image structure to an installation device, and obtain the corresponding target operating system installation file in the virtual image structure through the installation device;

providing a virtual optical drive to the server to be installed through the installation device,

The target operating system installation file is loaded onto the server to be installed through the virtual optical drive, so as to install the target operating system.

Preferably, in this embodiment, when the corresponding operating system is installed for the server cluster in the data center, the BMC may be preferentially selected as the installation device to install the target operating system. The virtual image structure can be sent to the corresponding client program implemented on the BMC, and the client program can analyze the address of the installation boot program (memory operation repair) file in the virtual image structure and the relevant drivers required for the installation of the boot program. address, the address of the image file of the target operating system, download the corresponding file according to the above file address, and verify it according to the corresponding MD5 value in the virtual image structure after downloading the corresponding file. After the verification is passed, follow the .iso The format is standardized, and the above-mentioned files are provided in binary form to the virtual CD-ROM drive that has been established on the server, and the installation boot program is run through the virtual CD-ROM drive.

In addition, for the data center, the above-mentioned files can be verified with the help of the security mechanism of the data center, that is, the installation of the boot program (in-memory operating system), the related drivers required for the installation of the boot program, and the target operating system image file with the software library of the data center Save and update the saving address to the virtual image structure. After receiving the virtual image structure, the BMC directly downloads the files from the software library, and provides the file image data to the virtual CD-ROM drive in accordance with the data order of the .iso file format specification.

Furthermore, when there are a large number of servers in the data center to install the operating system, by sending the virtual image structure to the BMC, the BMC obtains the corresponding part of the image data from the software library of the data center, and fully utilizes the software network of the data center to realize fast and parallel Batch installation to a large number of servers. And when the image data is obtained through the BMC network at the same time, the batch distribution of the installation image file data can be realized based on the network cache. Compared with the way that a single node generates an image and sends it to the BMC, the efficiency improvement is obvious.

It should be noted that the virtual mirror structure proposed by the present invention can exist in different forms according to different programming languages, and exist in the memory when the corresponding program is executed. When the virtual mirror structure needs to be saved, the virtual mirror can be The structure is stored in the database in the form of binary data, or persisted in the form of an XML format file exported according to the data structure of the virtual mirror structure, and loaded into the corresponding program when needed.
