FIG. 1 shows a flowchart of a method for installing an operating system according to an embodiment of the present disclosure. As shown in FIG. 1 , an embodiment of the present disclosure provides a method for installing an operating system, which is applied to a server, and the method includes:

S101: Obtain an image file of an operating system to be installed.

The operating system to be installed may be a Windows operating system, a Linux operating system, etc., or an Android operating system (a Linux-based free and open source operating system, mainly used for mobile terminals), an iOS operating system, and the like. The server may be a server of a terminal such as a desktop computer (PC), a notebook, a PDA, and a mobile phone, or a server of a large computer such as an industrial computer.

The image file of the operating system can be obtained in advance and recorded on a CD-ROM or stored in a storage device such as a USB flash drive. When the storage device is connected to the server, the server can obtain the image file. For example, the server can download and obtain the image file of the Win10 system from the network and put it in the corresponding folder of the boot U disk for installation. The server can also directly download the image file from the network. The image file can be an ISO image file or a GHO image file.

S102: Perform partition configuration on the hard disk of the server based on the image file to generate a partition configuration file.

After the server obtains the image file of the operating system to be installed, it can perform automatic partition configuration on the hard disk of the server according to the image file, generate a corresponding partition configuration file, and then automatically partition the hard disk according to the partition configuration file to realize automatic customization of hard disk partitions .

The partition configuration file is related configuration information for partitioning the hard disk, including the number of partitions and the partition parameters of each partition. The partition parameters of each partition may include a partition type, a partition name, a partition size, a partition order, a volume label, and the like.

The partition type is determined according to different division standards. For example, the partition type can be divided into FAT32, NTFS, and exFAT according to the hard disk file system format. The partition type can be divided into primary partition and logical partition according to whether it is physical memory; The types or uses of stored files are divided into system partitions (root partitions), boot partitions, backup partitions, and so on. The system partition mainly refers to a partition used to start the operating system. Usually, the root directory of the partition contains the startup files of the operating system (such as boot.ini, ntldr, etc.).

The server can partition the hard disk newly installed on the server according to the generated partition configuration file; it can also re-partition the hard disk partition according to the image file based on the original hard disk partition of the server. For example, you can increase or decrease the hard disk partition, Adjust the partition size of each hard disk partition, etc.

In this embodiment, the hard disk may be partitioned according to the file type of the image file. For example, for the Windows operating system, the hard disk of the server can be divided into C, D, E, F and other disks, and the C disk is mainly used for storing system files. For a Linux system, it can be divided into root partition (root partition), swap partition (swap partition), and other partitions.

In other implementations, the hard disk can also be partitioned according to the file size of the image file. For example, when the file size of the image file is large, the partition size of the root partition of the Linux system can be set larger to provide system files with a larger size. Sufficient storage space; and when the file size of the image file is small, the partition size of the root partition of the Linux system can be set to a smaller size to avoid waste of hard disk space.

Optionally, after determining the partition size of the divided hard disk partition, other partition parameters of the hard disk partition can be determined according to the partition size. When the size is much smaller than 4GB (for example, 1GB), the hard disk file system format of the hard disk partition can be determined as FAT32. FAT32 has better compatibility and is convenient for fast reading and writing; while the hard disk file system format of other hard disk partitions can be determined as NTFS, It supports files of more than 4GB, and the storage and reading and writing are convenient and fast; in order to ensure that the hard disk partition can support files of more than 4GB, the hard disk file system format of the hard disk partition can also be determined as exFAT to achieve better cross-platform capability, for example, exFAT is available for both WIN and MAC.

In a specific embodiment, the automatic partitioning of the hard disk is described in detail by taking the Linux system as an example. Among the hard disk partitions of the Linux system, the root partition and the swap partition are the basic partitions for installing the Linux system, and other partitions are optional partitions. The root partition is the partition where the operating system's kernel and files used during the boot process reside. The swap partition is used to release part of the space in the hard disk memory when the system's physical memory is insufficient for use by currently running programs. When the system memory is tight, the operating system saves some recently unused memory pages to the swap partition according to certain algorithm rules, thereby leaving enough memory space for programs that need memory; when the memory pages in the swap partition are accessed , the system will reload it into physical memory to run.

When partitioning the Linux system, in addition to dividing the hard disk partition into the root partition and the swap partition, it can also be divided into optional partitions such as the boot partition (boot partition), usr partition, home partition, var/log partition, and tmp partition. The above optional partition can be determined according to user needs. The boot partition contains the kernel of the operating system and the files used in the process of starting the operating system. Since most PCs are limited by the BIOS at present, in order to ensure the operation The boot partition can be set up separately for the smooth startup and installation of the system, and at the same time, it can also ensure that the operating system can still be started smoothly when the main root partition has a problem. The usr partition is used to store application software. To ensure the smooth installation and operation of each application software, as much space as possible should be allocated to the usr partition. The home partition is the location of the user's home directory, and its size depends on the number of users. If multiple users share the same server (for example, remote interaction), the root user (software vendor, etc.) can use the home partition to use the computer and The server interacts with each other for better control, such as limiting the use of hard disks to users and restricting ordinary users to access certain files. The var/log partition is the system log recording partition. If this separate partition is set, even if there is a problem with the system log file, it will not affect the root partition of the operating system. The tmp partition is used to store temporary files. This partition is necessary for multi-user systems or network servers, so that even if a large number of temporary files are generated when the program is running, or the user performs wrong operations on the system, the file system performs wrong operations. This part is still subjected to read and write operations, so it usually has problems faster than other parts, so that if the problem is found in time, the other parts of the file system can still be guaranteed to be safe.

In this embodiment, on the basis of determining the type of the image file, after the root partition and the swap partition are divided, the hard disk partition can be automatically customized according to user requirements and performance requirements of the server, such as whether to set the above-mentioned tmp partition, The partition size of the root partition is adjusted and so on.

In some embodiments, in step S102, partition configuration is performed on the hard disk of the server based on the image file, and a partition configuration file is generated, including:

The hard disk is partitioned based on the image file and the hard disk attributes of the hard disk, and a partition configuration file is generated.

The hard disk attribute includes attributes such as the hard disk capacity and the use status of the hard disk (whether it is a new hard disk).

Taking the Linux system as an example, if the hard disk space is large enough, more space can be divided into the root partition, so that the commonly used directories (such as downloaded software packages) can be newly created on the desktop without affecting the entry into the Linux system. speed. Therefore, in this embodiment, the partition size of each partition can be configured according to the capacity of the hard disk when partitioning, so as to further realize the automatic customization of the hard disk partition.

In some embodiments, the configuration of partitioning the hard disk according to whether the hard disk is a new hard disk includes: when the hard disk is a newly installed hard disk, partitioning the entire hard disk; and when the hard disk is a hard disk with existing partitions, it is not necessary to partition all the partitioned hard disks. To adjust the partition of the hard disk, you can keep some partitions of the hard disk, and only adjust the partition of the hard disk that needs to be adjusted. In this way, the partition efficiency of the hard disk can be improved.

S103: Install the image file based on the partition configuration file.

Step S103 specifically includes the following steps:

S1031: Generate an installation program based on the partition configuration file;

S1032: Guide the installation of the image file to a preset hard disk partition through the installation program.

After the hard disk of the server is customized and automatically partitioned according to the image file, the partition configuration file and the image file can be analyzed and processed, the installation program can be generated according to the partition configuration file and the image file, and the image file can be installed by using the installation program. Complete the installation of the operating system. The installation program is a customized operating system startup program generated according to the partition configuration file, and is used to guide the startup installation of the operating system.

When generating the installation program, the installation location of the image file can be determined according to the hard disk partition divided in step S102. For example, when the image file is a Linux system image file and the root partition is divided, the installation location of the image file image can be determined, namely for the root partition. Of course, the installation location of the image file may also be other hard disk partitions. For example, an installation location selection page may be added to the generated installation program to facilitate the user to select the corresponding installation location.

In specific implementation, the full_disk_policy.json script can be written to generate a partition configuration file, and the script can be injected into the original installation program of the operating system to realize automatic partition configuration of the hard disk and installation of the operating system. That is, the generated installation program can be generated on the basis of the original installation program of the operating system, and only needs to change the installation configuration parameters. The generated installer can also be a new installer that includes installation configuration parameters, and the new installer includes the full_disk_policy.json script described above.

In some embodiments, for the partition size of the root partition, the _{oem_settings.json} file can be written and packaged into the startup settings configuration in the installer, so that the partition size of the root partition can be determined after the hard disk is partitioned. Make adjustments to reasonably allocate the partition size of the root partition.

Since the root partition is a key partition of the hard disk, adjustment of the partition size of the root partition is mainly considered in the above embodiments. In specific implementation, different settings.json files can be written to adjust the partition size of different hard disk partitions.

In the operating system installation method provided by the embodiments of the present disclosure, after obtaining the image file of the operating system to be installed, partition configuration is performed on the hard disk of the server according to the image file, a partition configuration file is generated, and then the installation is performed according to the partition configuration file. The image file of the operating system can be customized and automatically partitioned on the hard disk of the server according to actual needs. Compared with the default partition of the hard disk, for example, after determining the number of partitions, the partition size of each partition is evenly distributed, which is convenient to adjust the partition size as needed, avoiding Some hard disk partitions have insufficient or wasteful capacity, which can effectively improve the performance of the server; in addition, manual partitioning operations are not required during the partitioning process (you only need to enter the relevant partition requirements before partitioning), which can improve the efficiency of operating system installation. In addition, the operating system installation method provided by the embodiment of the present disclosure can be applied to various scenarios such as research and development, testing, production, and on-site after-sales service, which can comprehensively improve enterprise efficiency and improve customer experience.

In some embodiments, the server is a heterogeneous platform and includes multiple processors. In step S102, partition configuration is performed on the hard disk of the server based on the image file, and a partition configuration file is generated, including:

Perform partition configuration on the hard disk based on the image file and the architectures of the plurality of processors, and generate a partition configuration file.

The heterogeneous platform can be a heterogeneous platform with multiple CPUs, and the CPU can include at least one of ARM, X86, and MIPS; the heterogeneous platform can also be a heterogeneous platform composed of a combination of at least two processors in the CPU, FPGA, and GPU. For example, a heterogeneous platform composed of different processors such as FPGA+CPU+GPU.

Different processors have different architectures. For example, compared with the X86 architecture, the ARM architecture has low power consumption and a high mobile market share, while X86 has high performance and a high server market share.

The image file of the operating system in this embodiment can simultaneously run in environments of different CPU architectures (for example, the above-mentioned ARM and X86). When performing partition configuration, the image files can be compiled under different CPU architecture environments, and then the partition configuration files under different CPU architectures can be generated, and then the partition configuration files under different CPU architectures can be integrated to obtain the final partition configuration. file, and then realize the automatic partitioning and installation of the operating system under the heterogeneous platform, and improve the universality of the operating system installation.

It should be noted that, in this embodiment, when the hard disk is partitioned and configured based on the image file and the architecture of the plurality of processors, the hard disk attributes may be considered at the same time, so as to realize a reasonable partition of the hard disk.

In some embodiments, as shown in FIG. 2 , the operating system includes at least a first operating system and a second operating system, and the method further includes:

S201: Perform partition configuration on the hard disk based on a first image file of the first operating system to generate a first partition configuration file;

S202: Perform partition configuration on the hard disk based on the second image file of the second operating system to generate a second partition configuration file;

S203: Integrate the first configuration file and the second configuration file to generate a third partition configuration file.

The first operating system and the second operating system are different, for example, the first operating system may be a Linux system, and the second operating system may be a Windows system, that is, the server can obtain different operating systems, and then, based on the corresponding image files, Generate the corresponding partition configuration file, and then integrate the generated different partition configuration files to generate the third partition configuration file, which can freely combine various hard disk partition formats under different operating systems, that is, the integrated third partition configuration The files can meet the partition format requirements of different operating systems to ensure the smooth installation of different operating systems in the future.

Further, the method also includes:

S204: Install the first image file and the second image file based on the third partition configuration file.

When both the first operating system and the second operating system need to be installed, the installation order of the two operating systems may be installed sequentially according to the default installation order, or may be determined according to actual needs, which is not specifically limited in the present disclosure.

An installation program, such as a GRUB (GRand Unified Bootloader) startup program, can select different kernels on the operating system partition, and pass startup parameters to these kernels, thereby realizing the startup installation of the operating system. GRUB is a multi-operating system startup program from the GNU project that bootstraps the installation of an operating system.

In other embodiments, when different operating systems need to be installed, after obtaining the first image file of the first operating system and the second image file of the second operating system, based on the first image file and the second image file , properties of the hard disk, and the architecture of the processor, etc., directly generate the third partition configuration file, that is, only the final partition configuration file needs to be generated.

It should be noted that, in addition to the above-mentioned first operating system and second operating system, the operating system may also be other operating systems. The hard disk can be a single hard disk or multiple hard disks. In particular, when the hard disk is multiple hard disks and the operating systems are different operating systems, different operating systems can be installed on the root partitions of different hard disks to facilitate subsequent smooth running of different application software in different operating systems.

In some embodiments, as shown in FIG. 3 , in step S103, installing the image file based on the partition configuration file includes:

S301: Make the image file of the operating system into a U disk boot disk;

S302: According to the partition configuration file, use the U disk boot disk to install the image file.

That is, in this embodiment, a native image file (for example, an ISO file) can be made into a U-disk boot disk, and the server deploys a customized and automatic configuration for the hard disk according to the image file, the hard disk attribute and/or the architecture of the processor, and after generating the partition configuration file, You can use the DiskGenius partition tool in the U disk boot disk to automatically partition the hard disk, and then install the operating system.

In other embodiments, as shown in FIG. 4 , in step S103, installing the image file based on the partition configuration file includes:

S401: Re-encapsulate the image file based on the partition configuration file to obtain a third encapsulated image file;

S402: Make the third image file into a bootable disk and install it.

In this embodiment, the server deploys a customized automatic configuration for the hard disk according to the image file, hard disk attributes and/or the architecture of the processor, and after generating the partition configuration file, the partition configuration file and the image file can be repackaged together to obtain the partition. Then, the third image file is made into a bootable disk (for example, burned into a CD) and installed, so as to realize the installation of the operating system.

In still other embodiments, as shown in FIG. 5 , in step S103, installing the image file based on the partition configuration file includes:

S501: Repackage the image file based on the partition configuration file to obtain a fourth image file;

S502: In response to the received pre-boot execution environment PXE boot instruction, boot and install the fourth image file based on the PXE network.

In this embodiment, the server deploys a customized automatic configuration for the hard disk according to the image file, hard disk properties and/or the architecture of the processor, and after generating the partition configuration file, repackages the partition configuration file and the image file together to obtain the partitioned configuration file. The fourth image file, the server performs PXE network startup according to the received remote pre-boot execution environment PXE startup instruction, loads the customized partitioned operating system into the memory of the server through the PXE network environment, starts the operating system, and then realizes Installation of the operating system.

As can be seen from the above, the automatic installation program of the operating system generated in this embodiment can universally support the use of various installation media (U disk boot disk, optical disk, network medium, etc.), thereby improving the convenience of operating system installation.

In some embodiments, before performing partition configuration on the hard disk of the server, the method further includes:

S601: Cut and remove a preset backup partition in the image file.

The system restore function that comes with the operating system can work only when the operating system can be started normally. When the user has a better backup solution, the backup partition that comes with the operating system cannot be trimmed, which affects the configuration of the backup partition.

In this embodiment, the preset backup partition in the image file can be trimmed and removed by setting the installation configuration parameters of the installation program, so that when the user has a better backup solution, the hard disk can be partitioned according to the backup solution, and a new backup partition can be configured. Backup partition.

Specifically, you can modify the /etc/default/grub file and set grub parameters to trim the backup partition that comes with the operating system. In specific implementation, it may be determined according to user requirements whether it is necessary to cut out the backup backup partition provided by the operating system.

Further, after trimming and removing the preset backup partition in the image file, the method further includes:

S701: Determine whether the "system backup and restore" startup option exists in the installation program corresponding to the image file;

S702: If it exists, trim and remove the "system backup and restore" startup option.

Wherein, the installation program corresponding to the image file is the customized automatic partition installation program generated based on the partition configuration file during the previous installation. After the operating system sets up the backup partition, the "system backup and restore" boot option is usually added directly to the boot selection page of the installer (such as grub) corresponding to the operating system (or image file). When grub reinstalls the operating system, this option will be added. If it occurs again, it may affect the configuration of the new backup partition.

In this embodiment, by judging whether there is a "system backup restore" startup option in the installer generated based on the partition configuration file, and trimming it out if it exists, the preset backup in the image file can be trimmed and removed. After partitioning, the "system backup and restore" startup option will be trimmed and removed simultaneously to ensure that the user has a better backup plan to configure a new backup partition based on the backup plan, to avoid the original "system backup and restore" startup option affecting the automatic partition of the hard disk. .

It can be understood that, since the above-mentioned customized automatic partition installation program can be generated on the basis of the original installation program of the operating system, for example, the original grub of the system is configured to generate a new grub. Therefore, in steps S701 and S702, the grub script /etc/grub.d/15_linux_bar of the operating system can be optimized by adding the grub macro option GRUB_DISABLE_RECOVERY=y, and the GRUB_DISABLE_RECOVERY parameter can be checked and judged to check whether the grub system boot menu is in the system boot menu. There is a "system backup and restore" startup option, if it exists (GRUB_DISABLE_RECOVERY=y), cut and remove the "system backup and restore" startup option, so that the user can realize the system backup and restore function based on the newly configured backup partition; if it does not exist (GRUB_DISABLE_RECOVERY= n), no cropping is required.

In particular, when it is detected that the "system backup and restore" startup option exists in the installer, the "system backup and restore" startup option can also be retained according to the user's needs, and packaged into the new automatic partition generated based on the newly configured backup partition. In the installation program, it is convenient to backup and restore the system when there is a problem with the installation of the operating system; or, after configuring the new backup partition, reconfigure the “system backup and restore” startup option in the installation program of the new automatic partition.

In this embodiment, through steps S701 and S702, it is possible to select whether to keep the "system backup and restore" startup option according to the actual needs of the user, so as to improve the reliability of the installation of the operating system.
