Description

Technical Field

[0001] This invention relates to the field of Linux operating system distribution development, mainly targeting the installation of Linux operating system on physical servers, especially in scenarios using PXE for installation. Specifically, it relates to an installation method and system for Linux operating system based on PXE adaptive hard disk driver. Background Technology

[0002] In recent years, with the development of the cloud computing industry, cloud computing has changed the way people access information and how enterprises build their information systems. Cloud computing is also considered the third wave of IT, a service related to information technology, software, and the internet. The rapid development of cloud computing also requires strong infrastructure support, among which the operating system that manages the server hardware and service capabilities of cloud resource pools is extremely important. Currently, cloud computing operating systems are generally Linux operating systems such as Red Hat and CentOS.

[0003] Currently, Linux operating systems are generally installed in two ways: one is to copy the Linux operating system ISO image file to a CD or USB drive and then insert it into the physical server for installation; the other is to import the Linux operating system ISO image file into a PXE server and then configure the appropriate environment for installation. In real-world projects, cloud computing resource pools contain a large number of servers of various models, which may be configured with different types of hard drives, such as RAID and NVMe. However, a Linux operating system distribution cannot be released simultaneously to support installation on all types of hard drives, because the ISO image file may lack drivers for certain types of hard drives. Current techniques generally require developers to unpack the Linux operating system distribution ISO image file, recompile the kernel vmlinuz or inject hard drive drivers to recreate the Initramfs, and then reconstruct and release the ISO image file before integrators can continue the installation. Therefore, current techniques suffer from problems such as the need for ISO image file re-distribution, lack of flexibility, and excessive time consumption. Summary of the Invention

[0004] In view of this, the present invention proposes an installation method and system for a Linux operating system based on a PXE adaptive hard disk driver. This method can make full use of the existing Linux operating system PXE installation mechanism, enabling the Linux operating system to automatically adapt to installation on various types of hard disks. When the Linux operating system does not support a certain hard disk driver, there is no need to recompile the kernel vmlinuz, inject the hard disk driver to recreate the Initramfs, or rebuild the ISO image file, thus improving R&D and operation and maintenance efficiency.

[0005] To achieve the above objectives, in a first aspect, the present invention provides an installation method for a Linux operating system based on a PXE adaptive hard disk driver, comprising the following steps:

[0006] Enhanced PXE protocol for transmitting hard drive driver RPM package software repository paths;

[0007] Create a hard drive driver RPM package software repository in the first directory of the PXE server;

[0008] Create a file in the second directory of the PXE server containing hard disk information and a hard disk driver mapping relationship file for the driver RPM package;

[0009] Update the PXE protocol, transfer the path of the hard drive driver rpm package software repository on the PXE server, and identify the hard drive model in the Live memory system environment;

[0010] Determine whether the target hard drive is supported in the Live memory system environment;

[0011] If the target hard drive is not supported, download the hard drive mapping file from the second directory of the PXE server;

[0012] Configure yum based on the PXE server IP and the hard drive driver rpm package repository path;

[0013] Download and cache the hard drive driver RPM to the Live memory system cache;

[0014] Install the hard drive driver RPM package and load the driver in the Live memory system environment;

[0015] Normal operating system software package installation; if the target hard drive is supported, proceed directly with the normal operating system software package installation.

[0016] Install the hard drive driver RPM package on the hard drive file system and update the kernel module configuration file.

[0017] As a further aspect of the present invention, the hard disk driver rpm package can be obtained from the hard disk hardware manufacturer, or a custom hard disk driver rpm package can be made for a specific Linux operating system distribution.

[0018] As a further aspect of the present invention, each line of data recorded in the hard disk driver mapping relationship file is used to indicate the name of the rpm package corresponding to the driver kernel module compiled by the hard disk for a specific Linux Kernel version.

[0019] As a further aspect of the present invention, the PXE protocol is used to transmit PXE server driver rpm package repository information. According to the RFC standard, Options 178, which has not yet been allocated in DHCP Options, is used as the carrier. In this case, the DHCP configuration file dhcpd.conf in the PXE server has an additional configuration item for the server driver rpm package repository information path.

[0020] As a further aspect of the present invention, when identifying the hard disk model in the Live memory system environment, the Live memory system environment automatically detects and obtains the hard disk's device type, device ID, and alias. When the Linux operating system selects the target hard disk during the installation process, it automatically detects the hard disk based on the / dev and / sys file systems to obtain the hard disk's device type, device ID, and alias.

[0021] As a further aspect of the present invention, determining whether the target hard disk is supported in the Live memory system environment includes the following steps:

[0022] Based on the obtained target hard drive alias information, search the system file / usr / lib / modules / 'kernel version' / module.alias to see if the system has a driver for the target hard drive;

[0023] If a driver for the target hard drive is available, use the `lsmod` command to check if the driver has been loaded. If not, use `insmod` to load the driver and proceed directly to the normal operating system package installation. If no driver for the target hard drive is available, configure the hard drive driver RPM package repository.

[0024] As a further aspect of the present invention, the hard disk driver rpm package repository is configured in the Live memory system environment, and the rpm package repository is configured according to the IP address of the PXE server and the path of the transmitted hard disk driver rpm package repository on the PXE server.

[0025] As a further aspect of the present invention, the installation method of the Linux operating system based on the PXE adaptive hard disk driver further includes:

[0026] Download the file containing the mapping relationship between hard disk information and PXE server driver rpm packages from the second directory on the PXE server;

[0027] Download the hard drive driver RPM package from the PXE server;

[0028] Install and load the hard drive driver RPM package in the Live memory system environment;

[0029] In a Live memory system environment, the Linux operating system installer installs the operating system packages according to normal logic.

[0030] As a further aspect of the present invention, the rpm package of the hard disk driver is downloaded from the PXE server, including:

[0031] Based on the hard disk information and the hard disk information driver rpm package mapping file obtained when configuring the hard disk driver rpm package repository in the Live memory system environment, as well as the obtained hard disk device type, device ID, and kernel version, the hard disk driver rpm package name is matched.

[0032] If the match is successful, the hard drive driver RPM package will be downloaded and cached in the Live memory system environment; otherwise, the installation will fail.

[0033] As a further aspect of the present invention, installing and loading the hard disk driver rpm package in the Live memory system environment includes:

[0034] Obtain the path to the hard disk driver RPM package cached in the Live memory system environment;

[0035] Use the system command `rpm -ivh 'hard disk driver rpm package'` to install the hard disk driver rpm package in the Live memory system environment.

[0036] Use the system command insmod to load the hard drive driver.

[0037] As a further aspect of the present invention, after directly performing normal operating system software package installation, it further includes:

[0038] Determine if the hard drive is supported;

[0039] If the hard drive is not supported, copy the hard drive driver rpm package from the Live memory system environment to the hard drive file system.

[0040] Switch to the hard drive file system;

[0041] Install the hard drive driver RPM package in the hard drive file system and update the kernel configuration file.

[0042] As a further aspect of the present invention, installing the hard disk driver rpm package on the hard disk file system and updating the kernel module configuration file includes:

[0043] In the Live memory system environment, locate the hard disk file system mount point / sysroot;

[0044] Use the system command `mkdir` to create a temporary directory ` / sysroot / new_disk`, and copy the hard drive driver RPM package to this directory;

[0045] Use the system command chroot / sysroot / to switch from the Live memory system environment file system to the hard disk file system;

[0046] Use the system command `rpm -ivh 'hard disk driver rpm package'` to install the hard disk driver rpm package on the hard disk file system. The corresponding hard disk driver ko file will be installed in the correct directory of the hard disk file system.

[0047] Use the system command 'depmod -a' to update the contents of the kernel module configuration file on the hard disk file system.

[0048] Secondly, the present invention also provides an installation system for a Linux operating system based on a PXE adaptive hard disk driver, comprising the following modules:

[0049] PXE Protocol Enhancement Module: Used to transmit the hard disk driver rpm package software repository path, using Option 178, which has not yet been assigned in DHCPOptions, as the carrier according to the RFC standard;

[0050] Hard disk driver software repository creation module: Creates a hard disk driver rpm package software repository in the first directory of the PXE server to store various types of hard disk driver rpm packages;

[0051] Hard disk information and driver mapping relationship creation module: Creates a hard disk driver mapping relationship file in the second directory of the PXE server, which contains hard disk information and driver rpm packages. Each line of data indicates the name of the rpm package corresponding to the driver kernel module compiled for a specific Linux Kernel version.

[0052] PXE Protocol Path Update Module: Updates the PXE protocol, transfers the path of the hard drive driver rpm package software repository on the PXE server, and identifies the hard drive model in the Live memory system environment;

[0053] Hard drive identification and support determination module: Automatically detects and obtains the device type, device ID and alias of the target hard drive in the Live memory system environment, and determines whether it supports installing an operating system on the target hard drive based on the obtained hard drive information;

[0054] Target hard drive processing module not supported: If the target hard drive is not supported, download the hard drive driver mapping file from the second directory of the PXE server;

[0055] PXE Server Configuration Module: Configures yum based on the PXE server's IP address and the hard drive driver rpm package repository path;

[0056] Hard drive driver download and caching module: Downloads and caches hard drive driver RPMs to the Live memory system cache for subsequent installation operations;

[0057] Hard disk driver installation and loading module: Installs and loads the hard disk driver RPM package in the Live memory system environment;

[0058] Normal operating system software package installation module: After the hard drive driver installation is completed, the normal operating system software package is installed;

[0059] Supports direct module installation on the target hard drive: If the target hard drive is supported, proceed directly with the normal operating system software package installation.

[0060] In another aspect, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program, which, when executed by the processor, performs any of the above-described installation methods of the Linux operating system based on a PXE adaptive hard disk drive according to the present invention.

[0061] In another aspect, the present invention provides a computer-readable storage medium storing computer program instructions that, when executed, implement any of the above-described installation methods of the Linux operating system based on a PXE adaptive hard disk drive according to the present invention.

[0062] Compared with existing technologies, the installation method and system for a Linux operating system based on a PXE adaptive hard disk driver proposed in this invention have the following advantages:

[0063] 1. Automatically detect and determine whether the installation of the operating system on the target device is supported during installation;

[0064] 2. Enhance the PXE protocol to enable it to transmit information such as the hard drive driver RPM package repository path;

[0065] 3. The Live memory system environment and hard disk file system work together in two stages to install hard disk drivers, solving the problems of not being able to install the operating system due to missing hard disk drivers in ISO image files and accessing the hard disk normally after the operating system is installed.

[0066] In summary, the installation method of the Linux operating system based on PXE adaptive hard disk driver of the present invention enables the Linux operating system to automatically adapt to the installation on various types of hard disks. When the Linux operating system does not support a certain hard disk driver, there is no need to recompile the kernel vmlinuz, inject the hard disk driver to recreate Initramfs, or rebuild the ISO image file, thus avoiding problems such as inflexibility and excessive cost.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit this application.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0078] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0079] The purpose of this invention is to provide an installation method and system for a Linux operating system based on a PXE adaptive hard drive driver. This method fully utilizes the existing Linux operating system's PXE installation mechanism, enabling the Linux operating system to automatically adapt to installation on various types of hard drives. Even when the Linux operating system does not support a certain hard drive driver, there is no need to recompile the kernel (vmlinuz), inject the hard drive driver to recreate Initramfs, or rebuild the ISO image file, thus improving development and maintenance efficiency.

[0080] To achieve the above objectives, this invention provides an installation method for a Linux operating system based on a PXE adaptive hard disk driver, comprising the following steps:

[0081] Step 1: Create a hard drive driver RPM package software repository

[0082] Hard drive driver RPM packages can be obtained from hard drive hardware manufacturers, or custom hard drive driver RPM packages can be created for a specific Linux operating system distribution. A software repository containing various types of hard drive driver RPM packages can be created in the first directory of the PXE server.

[0083] Step 2: Create a file mapping the hard drive information to its driver RPM package.

[0084] Create a file in the second directory of the PXE server that maps hard drive information to their corresponding driver RPM packages. This directory should be accessible to the PXE server process. Each line in the mapping file indicates the name of the RPM package corresponding to the driver kernel module compiled for a specific Linux Kernel version on that hard drive.

[0085] Step 3: Update the path of the PXE protocol transfer hard disk driver RPM package repository on the PXE server.

[0086] In the PXE protocol, to transmit PXE server driver RPM package repository information, Option 178, which is not yet assigned or used in DHCPOptions, is used as the bearer, according to the RFC standard. Simultaneously, the DHCP configuration file dhcpd.conf on the PXE server needs to add a configuration item for the server driver RPM package repository path, such as... Figure 4 As shown.

[0087] Step 4: The Live memory system environment automatically detects and obtains the hard drive's device type, device ID, and alias.

[0088] When selecting a target hard drive during the installation process, the Linux operating system automatically detects the hard drive based on the / dev and / sys file systems to obtain the hard drive's device type, device ID, and alias.

[0089] Step 5: Determine whether the target hard drive is supported in the Live memory system environment.

[0090] Based on the target hard drive alias information obtained in step 4, search the system file / usr / lib / modules / 'kernel version' / module.alias to see if the system has a driver for the target hard drive;

[0091] If a driver for the target hard drive is available, use the `lsmod` command to check if the driver is loaded. If not, use `insmod` to load the driver and proceed to step 10. If no driver is available for the target hard drive, proceed to step 6.

[0092] Step 6: Configure the hard disk driver RPM package repository in the Live memory system environment.

[0093] Configure the RPM package repository based on the PXE server's IP address and the path of the hard drive RPM package repository transmitted in step 3 on the PXE server.

[0094] Step 7: Download the file mapping the hard drive information to its driver RPM package.

[0095] Download the file containing the mapping relationship between the hard drive information and its driver rpm package from the second directory on the PXE server.

[0096] Step 8: Download the hard drive driver RPM package from the PXE server.

[0097] Based on the hard drive information and its driver RPM package mapping file obtained in step 6, and the hard drive's device type, device ID, and kernel version obtained in step 4, the hard drive driver RPM package name is matched. If the match is successful, the hard drive driver RPM package is downloaded and cached in the Live memory system environment; otherwise, the installation fails.

[0098] Step 9: Install and load the hard drive driver RPM package in the Live memory system environment.

[0099] Obtain the path to the hard disk driver RPM package cached in the Live memory system environment;

[0100] Use the system command `rpm -ivh 'hard disk driver rpm package'` to install the hard disk driver rpm package in the Live memory system environment.

[0101] Use the system command insmod to load the hard drive driver.

[0102] Step 10: The Linux operating system installer in the Live Memory System environment installs the operating system packages according to normal logic;

[0103] Step 11: Install the hard drive driver RPM package on the hard drive file system and update the kernel module configuration file.

[0104] In the Live memory system environment, locate the hard disk file system mount point / sysroot;

[0105] Use the system command `mkdir` to create a temporary directory ` / sysroot / new_disk`, and copy the hard drive driver RPM package to this directory;

[0106] Use the system command chroot / sysroot / to switch from the Live memory system environment file system to the hard disk file system;

[0107] Use the system command `rpm -ivh 'hard disk driver rpm package'` to install the hard disk driver rpm package on the hard disk file system. The corresponding hard disk driver ko file will be installed in the correct directory of the hard disk file system.

[0108] Use the system command 'depmod -a' to update the contents of the kernel module configuration file on the hard disk file system.

[0109] The embodiments of the present invention provide an installation method for a Linux operating system based on a PXE adaptive hard disk driver. During the installation, the method automatically detects and determines whether the installation of the operating system on the target device is supported. It enhances the PXE protocol to enable it to transmit information such as the hard disk driver rpm package repository path. The two-stage linkage of the Live memory system environment and the hard disk file system for hard disk driver installation solves the difficulties of not being able to install the operating system due to missing hard disk drivers in ISO image files and the difficulty of accessing the hard disk normally after the operating system is installed.

[0110] The present invention provides an installation method for a Linux operating system based on a PXE adaptive hard disk driver, which enables the Linux operating system to automatically adapt to the installation on various types of hard disks. When the Linux operating system does not support a certain hard disk driver, there is no need to recompile the kernel vmlinuz, inject the hard disk driver to recreate the Initramfs, or rebuild the ISO image file, thus avoiding problems such as inflexibility and excessive cost.

[0111] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of this invention will be further described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them.

[0112] In this embodiment, the Linux operating system ISO image file installed on the cloud computing resource pool server is ctyunos-2.0.1-220311-x86_64-dvd, the Linux kernel version is 4.19.90, the PXE server uses cobbler, and the hard disk controller is a RAID controller.

[0113] This embodiment describes an installation method for a Linux operating system based on a PXE adaptive hard disk driver, which includes the following steps:

[0114] Step 1: Obtain the hard drive driver RPM package from the hard drive hardware manufacturer, or create your own hard drive driver RPM package for a specific Linux operating system distribution. Create a first directory disk_repo under the / var / www / cobbler / directory on the PXE server, and use createrepo to create a software repository in this directory.

[0115] Step 2: Create a second directory `mapping_dir` under the ` / var / www / cobbler / ` directory on the PXE server, and create a file named `disk_rpm_mapping` in this directory that maps hard information to the names of their driver RPM packages. The file content is as follows:

[0116] v00009005d0000028->4.19.90-2102.2.0.0062->kmod-megaraid_sas;

[0117] v00009005d0000028->5.10.60-1->kmod-megaraid_sas;

[0118] v00008001d0000010->4.19.90-2102.2.0.0062->kmod-aacraid.

[0119] Step 3: Modify the configuration file ` / etc / dhcpd.conf` and add the configuration item `driver-repo: / var / www / cobbler / driver-repo / x86_64 / `. The PXE server stores the driver-repo in DHCPOptions 178 in its DHCP Offer message reply to PXE clients. The PXE client passes this to the PXE server when starting the Live Memory System environment.

[0120] Step 4: The installation environment automatically detects and obtains the hard drive's device type, device ID, and alias;

[0121] Based on the hard disk device type 00009005 and device ID 0000028 detected by the kernel, the corresponding modalias file is searched in the system file directory / sys / devices, and the alias of the target hard disk is obtained from the file: v00009005d0000028sv*sd*sc*.

[0122] Step 5: Determine whether the target hard drive is supported in the Live memory system environment;

[0123] According to the hard drive device alias, it is located in the system file / usr / lib / modules / 4.19.

[0124] The system searches for a corresponding hard drive driver .ko file in 90-2102.2.0.0062 / modules.alias. In this case, since there is no corresponding RAID .ko file, the process skips directly to step 6.

[0125] Step 6: The driver-repo obtained from the above steps: / var / www / cobbler / driver-repo / x86_64 /

[0126] And the IP address of the PXE server, next-server. Create the rpm package repository configuration file disk-driver.repo in the / etc / yum.repos.d / directory. The specific steps are as follows:

[0127] Set the baseurl in the disk-driver.repo configuration file to http: / / next-server / var / www / cobbler / driver-repo / x86_64

[0128] To enable the use of the software repository, set enabled=1 in the disk-driver.repo configuration file.

[0129] Use the system command `yum makecache` to download the metadata information of the hard drive driver RPM package repository from the PXE server and complete the RPM package software repository configuration.

[0130] Step 7: Use the command wget to download the disk information and its driver RPM package mapping file disk_rpm_mapping from the second directory mapping_dir on the PXE server;

[0131] Step 8: Based on the hard drive device type and device ID obtained in Step 4, determine the corresponding hard drive driver RPM package name as kmod-megaraid_sa-3.2-x86_64.rpm in the mapping file disk_rpm_mapping. Use the system command yumdownloader kmod-megaraid_sas to download the hard drive driver RPM package and cache it in the Live memory system environment;

[0132] Step 9: In the Live memory system environment, use the system command "rpm -ivh kmod-megaraid_sa-3.2-x86_64.rpm" to install the hard drive driver rpm package, and use the system command insmod megaraid_sas.ko to load the memory environment;

[0133] Step 10: The Linux operating system installer in the Live Memory System environment installs the operating system packages according to normal logic;

[0134] Step 11: Install the hard drive driver RPM package on the hard drive file system and update the kernel module configuration file. The specific steps are as follows:

[0135] The mount point of the hard disk device file / dev / sda is found to be / sysroot;

[0136] Create a new directory / sysroot / new_disk, and use the command cp kmod-megaraid_sa-3.2-x86_64.rpm / sysroot / new_disk to copy the driver to the hard drive file;

[0137] Use the system command "chroot / sysroot" to switch from the Live memory system environment file system to the hard disk file system;

[0138] Use the system command "rpm -ivhkmod-megaraid_sa-3.2-x86_64.rpm" to install the hard drive driver rpm package into the hard drive's file system;

[0139] Use the system command `depmod -a` to update the kernel module-related configuration files on the hard disk file system.

[0140] It should be noted that the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of the present invention, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Furthermore, it is readily understood that these processes may, for example, be executed synchronously or asynchronously in multiple modules.

[0141] It should be understood that although the above description follows a certain order, these steps are not necessarily executed in that order. Unless otherwise expressly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, some steps in this embodiment may include multiple steps or multiple stages, which are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be performed alternately or in turn with other steps or at least a portion of the steps or stages in other steps.
