FIG. 3 shows a flowchart of an operating system installation method 300 according to an example embodiment of the invention. As shown in fig. 3, step S310 is first executed to generate feature information and generate an installation information acquisition message according to the feature information.
In a computer, system booting is a very complicated process because the kernel of the operating system needs to detect hardware and load a proper driver, and then call various programs to prepare an environment for system operation, so that a user can smoothly operate the computer through the operating system.
According to one embodiment of the present invention, after the client is powered on, the client first enters a hardware self-test stage: the client hardware reads Basic Input Output System (BIOS) loading hardware information and carries out self-checking. Then entering a start-up boot phase: if the client side is provided with the operating system, the bootstrap program is loaded, and the kernel of the operating system is loaded into the internal memory according to the bootstrap program. According to one embodiment of the invention, when the operating system is implemented as a linux system, the boot program may be implemented as a GRUB2 operating system boot program. And finally, entering a system operation stage: and the kernel starts to operate, detects hardware information and loads a driver to enable the client to operate. At this point, the operating system has begun to work, and then the required programs can be loaded and subsequent work performed.
In the prior art, when an operating system is not installed in a client, a boot program is loaded during a boot stage, and the boot program is loaded into an operating system installer to install the operating system. The operating system installer is used to install the operating system in the device.
When a large-scale installation is performed, a PXE (preboot eXecution environment) is usually adopted, a boot program and an image file of an operating system are respectively sent to a plurality of computers for installation in a network resource manner, so as to test the operating system. According to one embodiment of the invention, the Client in the invention may be implemented as a PXE Client (PXE _ Client).
According to an embodiment of the present invention, the client generates the feature information first, so as to generate the installation information acquisition message according to the feature information. And when the client generates the characteristic information, generating the characteristic information according to the hardware information of the client. The hardware information includes: network card MAC, motherboard SN number, motherboard manufacturer, etc. The invention does not limit the type of the hardware information specifically used when the client generates the characteristic information, and the client can also synthesize various hardware information to generate the characteristic information.
Subsequently, step S320 is executed to acquire the installation information from the network server according to the installation information acquisition message. And after the client generates the characteristic information, acquiring the installation information from a preset storage position in a hardware self-checking stage. The predetermined storage location comprises network storage. The network storage stores installation information. The client establishes communication connection with the network server and sends installation information acquisition information to the network server.
The installation information acquisition message includes characteristic information of the client and a processor architecture of the client. According to one embodiment of the invention, the network server may determine the operating system to be installed by the client according to the processor architecture of the client.
According to an embodiment of the present invention, when the client has a specific installation requirement, a target operating system may be further added to the installation information obtaining message, and the network server uses the added target operating system as an operating system to be installed by the client.
After determining the operating system to be installed by the client, the network server generates installation information according to the storage position of the information file corresponding to the operating system in the resource server. The installation information also includes the address of the resource server.
Subsequently, step S330 is executed to obtain the first bootstrap program from the resource server according to the installation information. Specifically, the method comprises the following steps: and acquiring an information file from the resource server according to the installation information, and acquiring a first bootstrap program from the resource server according to the acquired information file.
The client establishes communication connection with the resource server according to the address of the resource server, and then acquires the information file from the resource server according to the installation information. According to an embodiment of the present invention, the information file may be implemented as a bootnetx64.efi file, and the present invention does not limit the specific type of the information file. The information file includes a storage location of the first bootstrap program in the resource server.
The resource server can acquire the characteristic information of the client from the network server, and according to the characteristic information of the client, the resource server can make a soft link for installing a real path stored by the operating system file, so that the real path of the requested file can be determined according to the soft link after the soft link sent by the client is received subsequently.
And the client side operates the first bootstrap program after acquiring the first bootstrap program from the resource server according to the acquired information file, and the first bootstrap program can search whether a loadable operating system exists. If the operating system which can be loaded does not exist, whether an operating system installation program and an image file exist is searched. If there is no os installer and no image file, step S340 is performed to generate a file obtaining address according to the feature information.
According to one embodiment of the present invention, when generating a file acquisition address according to the feature information, the file acquisition address is generated according to the feature information and the path parameter. The path parameter is a parameter of a path for storing an installation file required by installing the operating system, and is determined by the resource server when the installation file is stored. The installation files include operating system installation programs and image files. The client combines the characteristic information and the path parameters to obtain a file acquisition address of an installation file required by the installation operating system. According to an embodiment of the invention, the file acquisition address may be implemented as a soft link by which the true path of the file stored in the resource server can be determined. The resource server will also make a soft link to the real storage path, i.e. the file retrieval address. The soft link made by the resource server according to the characteristic information of the client is the same as the soft link generated by the client. According to the soft link sent by the client, the real path corresponding to the same soft link can be determined, and the client can obtain the installation file according to the real path. Because the hardware information of each client is different, the characteristic information generated by each client according to the hardware information is different. When the client generates the same characteristic information through the same hardware information. Therefore, through configuration, each client generates different file acquisition addresses according to the characteristic information, and acquires the required installation files from the different file acquisition addresses, thereby realizing installation of different operating systems.
According to one embodiment of the invention, the MAC address of the client is "aa: bb: cc: dd". The client transforms the MAC address first, and then converts the following: "replace with" _ ", get the character string: "aa _ bb _ cc _ dd" is the characteristic value of the client. The string "aa _ bb _ cc _ dd" is then compared to the path parameter: and the "/binary-installer/amd 64/live/vmlinux" is spliced to obtain the file acquisition address of the operating system installation program: "/debo-installer/amd 64/aa _ bb _ cc _ dd/live/vmlinux". The string "aa _ bb _ cc _ dd" is associated with the path parameter: the "/binary-installer/amd 64" is spliced to obtain the file acquisition address of the image file: "10.20.41.245:/var/nfs/amd 64/aa _ bb _ cc _ dd". The files required to install the operating system include operating system installers and image files. The client acquires the address through the file of the operating system installation program: "/binary-installer/amd 64/aa _ bb _ cc _ dd/live/vmlinux" and the file acquisition address of the image file: "10.20.41.245:/var/nfs/amd 64/aa _ bb _ cc _ dd", namely, the operating system installer and the image file can be respectively obtained from the resource server, and the operating system can be installed according to the operating system installer and the image file.
Subsequently, step S350 is executed, a second boot program is generated according to the file obtaining address and the first boot program, and the operating system installer and the image file are obtained from the resource server according to the second boot program. Specifically, the method comprises the following steps: and respectively taking the operating system installation program acquisition address and the image file acquisition address as a first parameter and a second parameter of the first bootstrap program to obtain a second bootstrap program.
According to one embodiment of the invention, the first boot program may be implemented as a grub. The client generates a file acquisition address, assigns the address of the acquired operating system installation program to the parameter linux as a first parameter, and assigns the address of the acquired image file to the parameter nfroot as a second parameter; a second boot program is obtained that includes the first parameter and the second parameter.
And then the client acquires the operating system installation program and the image file from the resource server through a second bootstrap program.
An example of the second boot procedure is specifically as follows:
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
set timeout=5
insmod gzio
menuentry "Install uos" {
set gfxpayload=keep
linux /debian-installer/amd64/live/vmlinuz root=/dev/nfs nfsroot=10.20.41.245:/var/nfs/amd64 console=tty boot=live components ethdevice-timeout=60 union=overlay locales=zh_CN.UTF-8 livecd-installer rw --
initrd /debian-installer/amd64/live/initrd.lz
}
menuentry "Try uos without installing" {
set gfxpayload=keep
linux /debian-installer/amd64/live/vmlinuz console=tty boot=live union=overlay quiet splash --initrd /debian-installer/amd64/live/initrd.lz
}。
according to one embodiment of the invention, after receiving the first parameter and the second parameter of the second lead sent by the client, the resource server determines the real path of the file stored in the resource server according to the first parameter and the second parameter. The file acquisition addresses in the first parameter and the second parameter are soft links of the real path, and the real path stored by the file can be determined through the reference relation of the file acquisition addresses to the real path. The resource server is manufactured with soft links in advance according to the real path and the characteristic value of the client, so that the real path of file storage is determined according to the soft links. And the resource server determines a real path stored by the operating system installation program according to the first parameter serving as the soft link and determines a real path stored by the image file according to the second parameter serving as the soft link.
The client then obtains the operating system installation program from the resource server according to the real path stored by the operating system installation program, and obtains the image file from the resource server according to the real path stored by the image file.
Finally, step S360 is executed to install the operating system according to the operating system installer and the image file. The client acquires the file in a soft link mode, so that the efficiency of acquiring the file from the resource server can be improved, and a plurality of servers can acquire the file from the resource server at the same time. Meanwhile, the resource server can also position the real paths of different files through different soft links, so that different clients can obtain different files.
FIG. 4 illustrates a schematic diagram of a client installation operating system according to an exemplary embodiment of the invention. As shown in fig. 4: firstly, the client generates characteristic information and generates an installation information acquisition message according to the characteristic information. And the client acquires the installation information from the network server according to the installation information acquisition message. And after determining the operating system to be installed by the client, the network server generates installation information according to the storage position of the information file in the resource server. The installation information also includes the address of the resource server.
And then, the client establishes communication connection with the resource server according to the address of the resource server and acquires an information file from the resource server according to the installation information.
And then, the client acquires a first bootstrap program from the resource server according to the acquired information file and runs the first bootstrap program.
And finally, when the client generates the file acquisition address according to the characteristic information, specifically generating the file acquisition address according to the characteristic information and the path parameter. The path parameter is a parameter of a path for storing an installation file required by installing the operating system, and is determined by the resource server when the installation file is stored. The client generates a second bootstrap program according to the file acquisition address and the first bootstrap program, and acquires an operating system installation program and a mirror image file from the resource server according to the second bootstrap program; and installing the operating system according to the operating system installation program and the image file.
Fig. 5 shows a schematic diagram of installing an operating system in the prior art. As shown in fig. 5: after the installation of the operating system is started, a boot program is executed first, and the operating system installer and the image file to be acquired are specified in the boot program. The operating system installer and the image file are then obtained from the boot program. And finally, installing the operating system according to the obtained operating system installation program and the image file. In the prior art, all computers provided with operating systems use the same bootstrap program, only the same operating system can be installed, and the operating systems cannot be installed in a customized manner according to the requirements of each computer.

As shown in fig. 6: after the installation is started, a first bootstrap program is acquired first. Specifically, the client generates the feature information first, and the feature information can be generated according to the hardware information; and then generating an installation information acquisition message according to the characteristic information and the processor architecture of the client, and sending the installation information acquisition message to the network server. The network server may determine the operating system to be installed by the client based on the processor architecture of the client. And after determining the operating system to be installed by the client, the network server generates installation information according to the storage position of the information file in the resource server. And the client acquires the first bootstrap program from the resource server according to the installation information.
Then, the client generates a file acquisition address according to the characteristic information; specifically, the method comprises the following steps: and generating a file acquisition address according to the characteristic information and the path parameter. The path parameter is a parameter of a path for storing an installation file required by installing the operating system, and is determined by the resource server when the installation file is stored. The installation files include operating system installation programs and image files. The client combines the characteristic information with the path parameters to obtain a file acquisition address of an installation file required by the installation operating system. Because the hardware information of each client is different, the characteristic information generated by each client according to the hardware information is different. Each client can generate the same characteristic information through the same hardware information. Therefore, through configuration, each client generates different file acquisition addresses according to the characteristic information, and acquires the required installation files from the different file acquisition addresses, thereby realizing installation of different operating systems.
Then, a second bootstrap program is generated according to the file acquisition address and the first bootstrap program, and an operating system installation program and an image file are acquired from the resource server according to the second bootstrap program. Specifically, the method comprises the following steps: and respectively taking the operating system installation program acquisition address and the image file acquisition address as a first parameter and a second parameter of the first bootstrap program to obtain a second bootstrap program. And after receiving the first parameter and the second parameter of the second guide lead sent by the client, the resource server determines a real path of the file stored in the resource server according to the first parameter and the second parameter. The file acquisition addresses in the first parameter and the second parameter are soft links of the real path, and the real path stored by the file can be determined through the reference relation of the file acquisition addresses to the real path. The resource server is manufactured with soft links in advance according to the real path and the characteristic value of the client, so that the real path of file storage is determined according to the soft links. And the resource server determines a real path stored by the operating system installation program according to the first parameter serving as the soft link and determines a real path stored by the image file according to the second parameter serving as the soft link.
Then, the operating system installer and the image file are obtained from the resource server according to the second bootstrap program, and the operating system is installed according to the operating system installer and the image file. The client acquires the file in a soft link mode, so that the efficiency of acquiring the file from the resource server can be improved, and a plurality of servers can acquire the file from the resource server at the same time. Meanwhile, the resource server can also position the real paths of different files through different soft links, so that different clients can obtain different files.
