Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application. The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

The PXE technology is a network boot technology developed by Intel corporation, works in a Client/Server (Client/Server) mode, allows a PXE Client to download a boot image from a PXE Server through a network, and loads an operating system installation package, thereby realizing batch installation of an operating system.

The PXE technology can only install an operating system to one hard disk of a specific disk drive (also referred to as a drive name), e.g., drive name sdb, while the slot location of the hard disk of each PXE client drive name sdb is unknown and the location on each PXE client slot is different. When an operating system is installed on a specified silk-screen number hard disk, the rest hard disks can only be pulled out, the specified silk-screen number hard disk is reserved or the specified silk-screen number hard disk is installed singly in a manual mode, and the flexibility of the two installation modes is poor, so that the operation and maintenance efficiency of operation and maintenance personnel is affected.

In view of this, the embodiments of the present application provide an operating system installation configuration method, which can implement that an operating system is installed on a hard disk indicated by a disk symbol corresponding to a silk-screen number specified by an operation and maintenance person, so as to improve flexibility of operating system installation.

The present application is further described below with reference to the drawings and embodiments.

In particular performing an operating system installation configuration, it may be implemented according to the method shown in FIG. 1. Fig. 1 is a flowchart of a method for operating system installation configuration according to an embodiment of the present application, as shown in fig. 1, where the method may include the following steps:

step S110, an executable file of the disk symbol mapping is obtained, and the executable file of the disk symbol mapping is used for establishing a mapping relation between the disk symbol and the silk screen number of each hard disk on the PXE client when being executed.

The PXE client may be a physical server, a notebook computer, or other electronic device that may install an operating system. For ease of description, the following will take a PXE client as an example of a physical server.

A plurality of hard disk slots are arranged on a hard disk backboard of the PXE client, the hard disk is inserted into the hard disk slots, and each hard disk slot is provided with a hard disk slot silk screen number and a logic position number (or called a physical slot number or a logic slot number).

The disk symbol mapping executable file can be a script file written by an operation and maintenance personnel and capable of running on the PXE client, and when the file is executed, a mapping relation between the disk symbol of each hard disk on the PXE client and a hard disk slot silk screen number (hereinafter referred to as a hard disk silk screen number) of the backboard can be established. The disc symbol mapping executable file and the automatic response file may be stored in the same working directory, or may be stored in other working directories according to a system requirement, for example, a system file of an operating system, which is not particularly limited in this application.

Specifically, when the PXE client runs the disk-symbol mapping executable file, the mapping relationship between the disk symbol and the silk-screen number of each hard disk may be established by a method as shown in fig. 2, and the method may include the following steps:

step S210, obtaining the disk symbols of all the hard disks on the PXE client, and determining a first corresponding relation between the disk symbols of all the hard disks and the logic position numbers.

The PXE client may include a plurality of PXE clients, and for convenience of description, the embodiments of the present application are illustrated with one PXE client. After the PXE client runs the executable file, the hard disk information of the PXE client may be read, for example, through a hard disk view command lsblk. For example, the hard disk drive name plugged onto the PXE client may be obtained by a lsblk-dno name command. After the hard disk drive name is obtained, the hard disk drive name may be stored, the storage form may be a plurality of groups or a Hash table, and the storage location may be a memory, which is not particularly limited in this application.

In some scenarios, the hard disk plugged by the PXE client includes only one type, taking the hard disk type as a SATA hard disk as an example, and the types of the hard disk identifier names obtained through the hard disk viewing command are the same, for example, sda, sdb. In this case, the serial number of each hard disk can be obtained from the hard disk drive name. Wherein the hard disk serial number is a unique identifier of the hard disk and can be used to identify a particular hard disk device.

In other scenarios, the hard disk drive of the PXE client includes multiple types, such as SAS, SATA, and NVME, where the corresponding serial number may be obtained according to each hard disk drive name of the different types.

Specifically, when the PXE client includes the first hard disks, the corresponding hard disk serial numbers may be searched first according to the disk symbols of each first hard disk. In some embodiments, the first hard disk may comprise a SAS and/or SATA type hard disk. Illustratively, the find command may be: smartctl-i/dev/[ disk name ] |grep-i "serial Number".

After the serial numbers of the hard disks of various types are obtained, the serial numbers of the hard disks and the corresponding drive letter names can be correspondingly stored, so that the relation between the drive letter names of the hard disks and the serial numbers of the hard disks is determined, the storage mode can be a hash table or a map (map) table, and the storage position can be a memory.

And acquiring the corresponding relation between the logical position number of each first hard disk and the serial number of the hard disk besides acquiring the serial number of each type of hard disk in the first hard disk. For example, the corresponding relationship between the serial number of each first hard disk and the logical location number may be obtained through a barcali command, where the barcali command may be: the stop/call/earl/sall show all j|grep-E "EID|SN".

After the relationship between the hard disk drive letter name and the hard disk serial number of each first hard disk and the corresponding relationship between the hard disk serial number and the logic position number are obtained, the corresponding relationship between the hard disk drive letter and the logic position number of each first hard disk can be established accordingly.

And under the condition that the PXE client comprises the second hard disks, searching the logical position numbers corresponding to the disk symbols of the second hard disks, and establishing the corresponding relation between the disk symbols of the second hard disks and the logical position numbers. The second hard disk may comprise an NVME type hard disk. By way of example, commands may be used: find/sys/device/-name to obtain the correspondence between the hard disk drive name and the logical location number of the NVME type.

In some embodiments, the second hard disk may also comprise a disk-group RAID type hard disk. For RAID type hard disks, a storage command may be used to obtain the correspondence between RAID drive names and corresponding logical location numbers. Illustratively, the store li command may be: the stop/call/vall show all j|grep-E "EID|OSdrive Name".

Step S220, determining a second corresponding relation between the hard disk silk-screen number and the logic position number of the PXE client according to the backboard type of the PXE client.

The backboard types of different PXE clients may include a plurality of types, such as an 8-disc backboard, a 24-disc backboard, a 12-disc backboard, etc., and the corresponding relationship between the hard disk silk-screen numbers and the hard disk logical numbers of the backboard of the PXE client of different manufacturers is different. When determining the second correspondence between the hard disk screen number and the logical position number, the back plate type of the PXE client may be obtained first. The backplane type may be obtained by a baseboard management controller (Baseboard Management Controller, BMC) using IPMI platform management tools. Specifically, the acquisition command may be: ipmitool raw [ data ], wherein [ data ] is a communication code for IPMI communication with BMC.

And besides the back plate type of the PXE client, the corresponding relation between the hard disk silk-screen number and the logic position number of the inserted hard disk can be obtained. The corresponding relationship between the hard disk silk-screen number and the logical position number of the inserted hard disk can be stored in the PXE server in advance and obtained when the PXE client requests the configuration file. The correspondence between the hard disk screen printing number and the logical position number of the inserted hard disk may be provided by the manufacturer or may be collected by an operation and maintenance person, which is not particularly limited in this application. According to the relation among the backboard type, the hard disk screen printing number and the logic position number of the inserted hard disk, a second corresponding relation between the hard disk screen printing number and the logic position number of the PXE client can be established.

And according to the first corresponding relation and the second corresponding relation, a mapping relation between the hard disk screen printing number and the drive letter of the PXE client can be established. Thus, the PXE client can acquire the drive letter name corresponding to the target silk-screen number of the installed operating system.

And step S120, generating a hard disk silk-screen number configuration file, wherein the hard disk silk-screen number configuration file is used for indicating a target silk-screen number, and the target silk-screen number represents the silk-screen number of the hard disk of the PXE client side for installing an operating system.

When the target silk-screen number for installing the operating system is obtained, the target silk-screen number can be input by operation and maintenance personnel according to the needs, so that the flexibility of installing the operating system can be improved. After the target silk-screen number is obtained, a hard disk silk-screen number configuration file can be generated according to the target silk-screen number, and the target silk-screen number is indicated through the file.

Of course, the target silk-screen number may also be pre-stored in the PXE server in the form of a hard disk silk-screen number configuration file.

In an alternative embodiment, the PXE service may be started after the hard disk drive number configuration file is generated, the PXE service may include a start dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP) service, a start simple file transfer protocol (Trivial File Transfer Protocol, TFTP) service, and a start file transfer protocol (File Transfer Protocol, FTP) service, the DHCP service may be used to dynamically assign an IP address to the PXE client, the TFTP service may be used to transfer system start files, and the FTP service may be used to provide download services of operating system files. The DHCP service, TFTP service, and FTP service may be integrated on a PXE server, or a plurality of servers, such as a DHCP server, a TFTP server, and an FTP server, may be configured according to service types, and for ease of understanding, the following description will be given by taking, as an example, configuration of each service on one PXE server.

In actual operation, the time of starting the PXE service may also be selected according to actual needs, which is not particularly limited in the present application.

It is to be understood that the PXE services initiated by the present application include, but are not limited to, DHCP services, TFTP services, and FTP services described above, and may also include Apache services, for example. In addition, the embodiments of the present application are exemplified by the file transfer service through the FTP service, and in some embodiments, the file transfer service may also be implemented through the HTTP service or the NFS service.

And 130, generating an automatic response file, wherein the automatic response file is used for running the drive letter mapping executable file when being executed by the PXE client, acquiring a target silk-screen number indicated by the hard disk silk-screen number configuration file, and installing an operating system on a hard disk indicated by the drive letter corresponding to the target silk-screen number.

When the PXE client installs the operating system through the bootstrap program, it is cumbersome to manually operate the operation and maintenance personnel because various settings, such as an administrator account, a system language setting, etc., need to be performed. In embodiments of the present application, these settings may be used to generate an automated response document (or referred to as an unattended installation document) that may be used to automatically install an operating system. The file can be loaded by one key during system installation, so that the PXE client can be automatically set during installation of an operating system, complicated manual operation is omitted, and the working efficiency of operation and maintenance personnel can be improved.

Taking an automatic response tool as a Kickstart as an example, in the process of installing the Kickstart, the Kickstart can record various parameters and operation commands configured by operation and maintenance personnel and generate an automatic response file. In the case that the PXE client has parameters to be filled in and configuration files to be loaded in the installation process of the operating system, the installer will first find whether the appropriate parameters exist in the auto-answer file, and if so, use the parameters. According to the method and the device for the automatic response file configuration, the command of the executable file for the disk symbol mapping can be configured in the automatic response file, the command of the target silk-screen number indicated by the hard disk silk-screen number configuration file is obtained, so that the PXE client can run the disk symbol mapping executable file under the instruction of the automatic response file when the operating system is installed, the mapping relation between the disk symbol of each hard disk on the PXE client and the silk-screen number is obtained, the target silk-screen number indicated by the hard disk silk-screen number configuration file is obtained, and the corresponding disk symbol name is obtained according to the target silk-screen number.

When the file transfer service is FTP, the generated automatic response file may be stored under var/FTP/directory, and when the file transfer service is HTTP, the generated automatic response file may be stored under var/www/html/directory. It will be appreciated that the storage path of the auto-answer file may also be selected according to actual needs.

Considering that the PXE client is usually installed on the first hard disk of the PXE client when the operating system is installed, the auto-answer file may also be used to instruct the PXE client to modify sda in the ignoredisk-only-use=sda statement of the auto-answer file to the name of the disk corresponding to the target silk-screen number when the operating system is installed, so that the PXE client may install the operating system on the hard disk indicated by the disk corresponding to the target silk-screen number.

In an alternative implementation manner, when the operating system is installed, the PXE client side is further configured to instruct the PXE client side to install the operating system on the hard disk of the preset disk symbol when the corresponding disk symbol is not found according to the target silk-screen number indicated by the hard disk silk-screen number configuration file. The preset disc symbol may be set by an operation and maintenance personnel according to actual needs, and may be the same as sda in the ignoredisk-only-use=sda statement, or may be different, which is not particularly limited in the embodiment of the present application.

Of course, the target silk-screen number in the hard disk silk-screen number configuration file may also include a plurality of target silk-screen numbers, for example, the target silk-screen number may include a first target silk-screen number and a second target silk-screen number, when the PXE client obtains the target silk-screen number indicated by the hard disk silk-screen number configuration file, the PXE client obtains the first target silk-screen number by default, stores the first target silk-screen number into a temporary variable, and when the PXE client runs a disk symbol mapping executable file to establish a mapping relationship between the disk symbol and the silk-screen number of each hard disk, the variable is transferred, so that the PXE client can obtain a disk symbol name corresponding to the first target silk-screen number, and stores the disk symbol name into the temporary variable. The sda in the ignoredisk-only-use=sda statement is then modified to the value of the temporary variable (the disk name corresponding to the first target silk-screen number).

Under the condition that the corresponding disk character does not exist in the first target silk-screen number, a second target silk-screen number indicated by the hard disk silk-screen number configuration file can be obtained, the second target silk-screen number is stored to a temporary variable, under the condition that the corresponding disk character exists in the second target silk-screen number, the sda in the ignoredik-only-use=sda statement is modified to be the value of the temporary variable (the disk character name corresponding to the second target silk-screen number), and therefore the PXE client can install an operating system on the hard disk indicated by the disk character corresponding to the second target silk-screen number.

In an alternative implementation, the PXE client does not modify the ignoredisk-only-use=sda statement of the auto-answer file in the absence of a corresponding drive letter for the target silk-screen number, so that the PXE client can install the operating system on the default drive letter.

After the configuration is completed, the PXE client can be started, and the PXE client can automatically find the DHCP service related to the PXE server, and the DHCP service can respond to the broadcast request of the PXE client, allocate an IP address to the PXE client, and inform the PXE client of the addresses of the boot program and related configuration files, for example, inform the storage path of the boot program under the TFTP service/var/lib/tftpboot/work directory. The TFTP service prepares a Linux kernel, initializes an image file (or called a Linux boot loading module), a boot program, and the like, and may transmit the boot program and the Linux kernel to the PXE client in response to a request for the PXE client to acquire the boot file after receiving the request. The PXE client may load a boot program with a Linux kernel and associated configuration files into memory for managing the installation of the operating system at the PXE client.

After the PXE client obtains the bootstrap program, the bootstrap program can be run, the bootstrap installation flow is entered, and a request for obtaining an operating system installation package, an executable file of the disk symbol mapping, a configuration file of the hard disk screen printing number, an automatic response file and the like is initiated to the FTP service of the PXE server. The FTP service may send an operating system installation package, an logout mapping executable file, a hard disk silk-screen number configuration file, and an auto-answer file to the PXE client in response to an acquisition request from the PXE client.

After the PXE client acquires the system installation package, the disk symbol mapping executable file, the hard disk silk-screen number configuration file and the automatic response file, the automatic response file is executed to start installing the operating system, and the operating system is installed on the hard disk indicated by the disk symbol corresponding to the target silk-screen number through the first execution instruction, the second execution instruction and the third execution instruction in the automatic response file to execute the installation operation. The first execution instruction is used for configuring an executable file of the disk symbol mapping, comprises loading and running of the executable file of the disk symbol mapping, and is used for establishing a mapping relation between the disk symbol of each hard disk and the silk screen number; the second execution instruction is used for acquiring a target silk-screen number in the hard disk silk-screen number configuration file, and modifying the sda in the ignoredisk-only-use=sda statement of the disk symbol in the automatic response file into a disk symbol name corresponding to the target silk-screen number; and the third execution instruction is used for installing the operating system on the hard disk indicated by the disk symbol corresponding to the target silk screen number.

The embodiment of the present application is exemplified by taking an automatic response tool as a kirkstart, and of course, the automatic response tool may also be other tools, such as Cobbler, which is not described herein.

Those skilled in the art will appreciate that the above embodiments are exemplary and not intended to limit the present application. The order of execution of one or more of the above steps may be modified, if possible, or may be combined selectively to yield one or more other embodiments. Those skilled in the art can select any combination from the above steps according to the need, and all the steps do not depart from the spirit of the scheme of the present application.
