Installation method and system of Linux operating system based on PXE adaptive hard disk drive

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 14, 2023, with application number 202311720325.2 and invention name “Installation method and system for Linux operating system based on PXE adaptive hard disk drive”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] This application relates to the field of Linux operating system distribution research and development, mainly targeting the installation of Linux operating systems on physical servers, especially the scenario of installation using PXE, and specifically to a method and system for installing Linux operating systems based on PXE adaptive hard disk drive. Background Art

[0004] In recent years, the development of the cloud computing industry has transformed how people access information and how businesses build information systems. Considered the third wave of IT, cloud computing is a service related to information technology, software, and the internet. The rapid growth of cloud computing requires strong infrastructure support, particularly the operating system that manages the server hardware and service capabilities of cloud computing resource pools. Currently, cloud computing operating systems are typically Linux operating systems such as Red Hat and CentOS.

[0005] Currently, Linux operating systems are generally installed in two ways: one is to download the Linux operating system ISO image file to a CD or USB drive and then insert it into a physical server for installation; the other is to import the Linux operating system ISO image file into a PXE server and then configure the corresponding environment for installation. In actual projects, cloud computing resource pools have a large number of servers of various models, and different servers may be equipped with different types of hard drives, such as RAID and NVME. However, a Linux operating system distribution may not support installation on all types of hard drives at the same time when it is released, because the ISO image file may lack the driver for a certain type of hard drive. Existing technical methods generally require R&D personnel to decompress the Linux operating system distribution ISO image file, recompile the kernel vmlinuz or inject hard drive drivers to recreate Initramfs, and then reconstruct and publish the ISO image file before the integrator can proceed with the installation. Therefore, existing technical methods suffer from problems such as the need to republish ISO image files, lack of flexibility, and long time consumption. Summary of the Invention

[0006] In view of this, the present application proposes a method and system for installing a Linux operating system based on a PXE adaptive hard disk drive, which can make full use of the existing Linux operating system PXE installation mechanism and enable 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 drive, there is no need to recompile the kernel vmlinuz, inject the hard disk driver to recreate Initramfs, and there is no need to reconstruct the ISO image file, thereby improving R&D and operation and maintenance efficiency.

[0007] Based on the above objectives, in a first aspect, the present application provides a method for installing a Linux operating system based on a PXE adaptive hard disk drive, comprising the following steps:

[0008] Enhanced PXE protocol transmission of hard disk drive RPM package software repository path;

[0009] Create a hard drive rpm package repository in the first directory on the PXE server;

[0010] On the second day of recording on the PXE server, create the hard disk information and hard disk drive mapping relationship file of the driver RPM package;

[0011] Updated the PXE protocol to transmit the path of the hard drive RPM package repository on the PXE server and identify the hard drive model in the Live Memory system environment;

[0015] Download and cache the hard drive rpm to the Live memory system cache;

[0016] Install the hard disk driver RPM package in the Live memory system environment and load the driver;

[0017] Install the operating system software package normally. If the target hard disk is supported, directly install the operating system software package normally.

[0023] As an optional solution of the present application, determining whether the target hard disk is supported in the Live memory system environment includes the following steps:

[0024] Based on the obtained target hard disk alias information, check whether the system has the target hard disk driver from the system files, usr, lib, modules, "kernel version" or module.alias;

[0025] If there is a driver for the target hard disk, call the lsmod command to confirm whether the hard disk driver has been loaded. If not, call insmod to load the hard disk driver and jump directly to the normal operating system software package installation. If there is no driver for the target hard disk, configure the hard disk driver rpm package repository.

[0026] As an optional solution of the present application, the hard disk drive RPM package warehouse is configured in the Live memory system environment, and the RPM package warehouse is configured according to the IP address of the PXE server and the path of the transmitted hard disk drive RPM package warehouse on the PXE server.

[0034] If the match is successful, the hard disk driver rpm package is downloaded and cached in the Live memory system environment. Otherwise, the installation fails.

[0035] As an optional solution for this application, install the hard disk driver RPM package in the Live memory system environment and load it, including:

[0036] Get the path of the hard disk drive RPM package in the cache of the Live memory system environment;

[0037] Use the system command rpm-ivh 'hard disk drive rpm package' to install the hard disk drive rpm package in the Live memory system environment;

[0038] Use the system command insmod to load the hard disk driver.

[0039] As an optional solution for this application, after directly installing the normal operating system software package, it also includes:

[0040] Determine whether the hard disk is supported;

[0041] If the hard disk is not supported, copy the hard disk driver rpm package from the Live memory system environment to the hard disk file system;

[0042] Switch to the hard disk file system;

[0043] Install the hard disk driver RPM package in the hard disk file system and update the kernel configuration file.

[0044] As an optional solution for this application, install the hard disk driver RPM package on the hard disk file system and update the kernel module configuration file, including:

[0077] To make the purpose, technical solutions and advantages of this application more clearly understood, the following is a further detailed description of the embodiments of this application in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0078] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0079] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0080] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0081] The purpose of this application is to provide a method and system for installing a Linux operating system based on a PXE-adaptive hard drive driver. This method can fully utilize the existing Linux operating system PXE installation mechanism and enable the Linux operating system to automatically adapt to installation on various types of hard drives. In the case where 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, and even reconstruct the ISO image file, thereby improving R&D and operation and maintenance efficiency.

[0082] To achieve the above object, the present invention provides a method for installing a Linux operating system based on a PXE adaptive hard disk drive, comprising the following steps:

[0083] Step 1: Create a hard drive rpm package repository

[0084] Obtain the hard disk drive RPM package from the hard disk hardware manufacturer, or create your own hard disk drive RPM package for a specific Linux operating system distribution. Create a software repository for various types of hard disk drive RPM packages in the first directory on the PXE server.

[0085] Step 2: Create a mapping file between the hard disk information and its driver rpm package

[0086] Create a mapping file between hard drive information and its driver RPM package in the second directory on the PXE server. This directory should be accessible to the PXE server process. Each line of data in the mapping file indicates the RPM package name corresponding to the driver kernel module compiled for a specific Linux kernel version on a specific hard drive.

[0087] Step 3: Update the PXE protocol to transfer the hard drive RPM package repository path on the PXE server

[0088] To transmit the PXE server driver RPM package repository information during the PXE protocol, the unused DHCP Option 178 is used as the carrier according to the RFC standard. Furthermore, the DHCP configuration file dhcpd.conf on the PXE server needs to add a path to the server driver RPM package repository, as shown in Figure 4.

[0089] Step 4: Automatically detect and obtain the hard disk device type, device ID, and alias in the Live memory system environment

[0090] When the Linux operating system selects the target hard disk during installation, 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.

[0091] Step 5: Determine whether the target hard disk is supported in the Live memory system environment

[0092] 1) Based on the target hard disk alias information obtained in step 4, check whether the system has the target hard disk driver from the system file / usr / lib / modules / 'kernel version' / module.alias.

[0093] 2) If there is a driver for the target hard disk, call the lsmod command to confirm whether the hard disk driver has been loaded. If not loaded, call insmod to load the hard disk driver and jump to step 10. If there is no driver for the target hard disk, jump to step 6.

[0094] Step 6: Configure the hard drive rpm package repository in the Live memory system environment

[0095] Configure the RPM package repository based on the IP address of the PXE server and the path of the hard disk drive RPM package repository on the PXE server transferred in step 3.

[0096] Step 7: Download the mapping file between the hard disk information and its driver rpm package

[0097] Download the mapping file between the hard disk information and its driver RPM package from the second directory on the PXE server.

[0098] Step 8: Download the RPM package for the hard drive from the PXE server

[0099] Based on the mapping file between the hard drive information and its driver RPM package obtained in step 6, as well as 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 a match is successful, the hard drive driver RPM package is downloaded and cached in the Live Memory system environment. Otherwise, the installation fails.

[0100] Step 9: Install the hard disk drive rpm package and load it in the Live memory system environment

[0101] 1) Get the path of the hard disk drive RPM package in the cache of the Live memory system environment;

[0102] 2) 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;

[0103] 3) Use the system command insmod to load the hard disk driver.

[0104] Step 10: In the Live Memory System environment, the Linux OS installer installs the OS software package according to normal logic.

[0105] Step 11: Install the hard disk driver rpm package on the hard disk file system and update the kernel module configuration file

[0106] 1) Find the hard disk file system mount point / sysroot in the Live memory system environment;

[0107] 2) Use the system command mkdir to create a new temporary directory / sysroot / new_disk and copy the hard disk driver RPM package to this directory;

[0108] 3) Use the system command chroot / sysroot / to switch from the Live memory system environment file system to the hard disk file system;

[0109] 4) 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 to the correct directory of the hard disk file system;

[0110] 5) Use the system command 'depmod -a' to update the kernel module configuration file content on the hard disk file system.

[0111] The embodiments of the present application provide a method for installing a Linux operating system based on a PXE adaptive hard disk drive. During the installation, the method automatically detects and determines whether the operating system installation on the target device is supported, enhances the PXE protocol so that it has the ability to transmit information such as the hard disk drive RPM package repository path, and implements a two-stage linkage hard disk drive installation using the Live memory system environment and the hard disk file system. This solves the problems of the hard disk drive being unable to install the operating system when the ISO image file is missing and the difficulty of normally accessing the hard disk after the operating system installation is completed.

[0112] The present application discloses a method for installing a Linux operating system based on a PXE adaptive hard disk drive, which enables 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 drive, there is no need to recompile the kernel vmlinuz, inject the hard disk drive to recreate Initramfs, or reconstruct the ISO image file, thereby avoiding problems such as technical inflexibility and excessive cost.

[0113] In order to make people in this technical field better understand the technical solution of this application, the technical solution of this application is further described below in conjunction with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0114] 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.

[0115] The present embodiment provides a method for installing a Linux operating system based on a PXE adaptive hard disk drive, and the installation includes the following steps:

[0116] Step 1: Obtain the hard disk driver RPM package from the hard disk hardware manufacturer, or create a hard disk driver RPM package for a specific Linux operating system distribution. Create a second directory disk_repo in the / var / www / cobbler / directory on the PXE server and use createrepo to create a software repository in this directory.

[0117] Step 2: Create the first directory mapping_dir in the / var / www / cobbler / directory on the PXE server, and create a file disk_rpm_mapping in this directory that maps the hardware information to the name of the driver RPM package. The file content is as follows:

[0118] Step 3: Modify the / etc / dhcpd.conf configuration file and add the driver-repo: / var / www / cobbler / driver-repo / x86_64 / configuration item. The PXE server stores the driver-repo in DHCP Options 178 in the DHCP Offer message it sends to the PXE client. The PXE client passes this information to the PXE server when booting the Live Memory system environment.

[0119] Step 4: Automatically detect and obtain the hard disk's device type, device ID, and alias in the installation environment;

[0120] According to the hard disk device type 00009005 and device ID 0000028 detected by the kernel, the corresponding modalias file is found in the system file directory / sys / devices, and the alias-pci:v00009005d0000028sv*sd*sc* of the target hard disk is obtained from the file.

[0121] Step 5: Determine whether the target hard disk is supported in the Live memory system environment;

[0122] According to the hard disk device alias in the system file / usr / lib / modules / 4.19.

[0123] Check if there is a corresponding hard drive ko file in 90-2102.2.0.0062 / modules.alias. In this case, since there is no ko file corresponding to RAID, skip to step 6 directly;

[0124] Step 6: Driver-repo obtained from the above steps: / var / www / cobbler / driver-repo / x86_64 /

[0125] 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:

[0126] 1. Set baseurl in the disk-driver.repo configuration file to http: / / next-server / var / www / cobbler / driver-repo / x86_64

[0127] 2. Set enabled=1 in the disk-driver.repo configuration file to enable the use of the warehouse software repository;

[0128] 3. Use the system command yum makecache to download the metadata information of the hard disk drive RPM package warehouse from the PXE server to complete the RPM package software warehouse configuration.

[0129] Step 7: Use the wget command to download the disk_rpm_mapping file, which maps the hard disk information to its driver RPM package, from the second directory mapping_dir on the PXE server.

[0130] Step 8: Based on the hard disk device type and device ID obtained in Step 4, determine the RPM package name for the corresponding hard disk drive in the mapping file disk_rpm_mapping: kmod-megaraid_sa-3.2-x86_64.rpm. Use the system command yumdownloader kmod-megaraid_sas to download the hard disk drive RPM package and cache it in the Live memory system environment.

[0131] 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 disk driver RPM package, and use the system command insmod megaraid_sas.ko to load the memory environment;

[0132] Step 10: In the Live Memory System environment, the Linux OS installer installs the OS software package according to normal logic.

[0133] Step 11: Install the hard disk driver RPM package on the hard disk file system and update the kernel module configuration file. The specific steps are as follows:

[0134] 1. Find the mount point of the hard disk device file / dev / sda as / sysroot;

[0135] 2. 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 disk file;

[0136] 3. Use the system command "chroot / sysroot" to switch from the Live memory system environment file system to the hard disk file system;

[0137] 4. Use the system command "rpm-ivhkmod-megaraid_sa-3.2-x86_64.rpm" to install the hard disk driver RPM package into the hard disk file system;

[0138] 5. Use the system command depmod -a to update the kernel module related configuration files on the hard disk file system.

[0139] It should be noted that the above figures are merely illustrative of the processes included in the methods according to exemplary embodiments of the present application and are not intended to be limiting. It is readily understood that the processes illustrated in the above figures do not indicate or limit the temporal order of these processes. Furthermore, it is readily understood that these processes may be executed synchronously or asynchronously, for example, in multiple modules.

[0140] It should be understood that, although the above is described in a certain order, these steps are not necessarily performed in sequence according to the above order. Unless there is clear explanation in this article, the execution of these steps does not have strict order restriction, and these steps can be performed in other orders. Moreover, a part of the steps of the present embodiment may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be performed in turn or alternately with at least a portion of the steps or stages in other steps or other steps.
