Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
At present, the production of an ISO image with an automatic installation function generally includes the following steps: extracting the content in the original ISO file to a temporary directory; putting the automatic response file into the temporary directory, and modifying the Bootloader configuration file under the temporary directory; and repackaging the content under the temporary directory to manufacture a new ISO mirror image file. The process of extracting and analyzing the ISO mirror image file and repackaging the ISO mirror image file is slow, and the temporary directory occupies extra space. Based on the method, the device and the equipment, the method, the device and the equipment for modifying the ISO image file are provided. The following first provides a detailed description of a method for modifying an ISO image according to an embodiment of the present disclosure.
Fig. 1 shows a flowchart of a method for modifying an ISO image according to an embodiment of the present disclosure. The method is applied to equipment for manufacturing the ISO image file, such as equipment of a computer or a server. As shown in fig. 1, the method comprises the steps of:
step S102, storing the automatic response file corresponding to the target ISO mirror image file to a first area of a system reserved area of the target ISO mirror image file.
Wherein the first area may be a randomly selected or user-designated area for storing the auto-answer file. The size of the first area may be determined according to the size of the auto-answer file. The target ISO mirror image file is an ISO mirror image file without an automatic installation function. For example, the target ISO image file may be in the format of ISO9660 (e.g., installation files for Linux systems, VMware systems, Xen systems, etc.). ISO9660 is a general optical disc file system established by the international organization for standardization.
The target ISO mirror image file is modified into an ISO mirror image file with an automatic installation function, and a configuration file, namely an automatic response file, needs to be added into the target ISO mirror image file. The auto-answer file is preset, and may be selected from existing auto-answer files. The formats of the auto-answer files corresponding to different operating systems are different, so that the auto-answer file corresponding to the target ISO image file is selected to be stored in the first area of the system reserved area of the target ISO image file. The system reserved area of the ISO image is typically located at the beginning of the ISO image.
And step S104, modifying the guide configuration file of the target ISO mirror image file according to the file name of the automatic response file.
The boot configuration file is also called Bootloader configuration file, and is a boot file when the operating system is installed. After adding the automatic response file in the system reserved area of the target ISO mirror image file, modifying the Bootloader configuration file of the target ISO mirror image file, wherein parameters corresponding to the automatic response file are added in the Bootloader configuration file, and the parameters comprise the file name of the automatic response file. The format of the automatic response file is different for different operating systems, and the parameters added in the Bootloader configuration file are also different. For example, for a Linux system, the parameters added in the Bootloader configuration file may be: ks ═ isolinux/splash. Png is the file name of the auto-answer file.
And step S106, storing the modified guide configuration file to a second area of the system reserved area.
Since it is difficult to directly overlay the Bootloader configuration file in the target ISO image file, the modified Bootloader configuration file may be stored to the second area in the system reserved area. Wherein, the second region and the first region are two non-overlapping regions. The size of the second area is determined according to the size of the Bootloader configuration file.
Step S108, parameters in the corresponding file description structure are modified according to the file sizes and the initial positions of the automatic response file and the modified guide configuration file respectively, so that the ISO mirror image file has an automatic response function; wherein, the file description structure is used for recording the size parameter of the file and the starting position parameter of the file.
The file description structure is also denoted as Directory Record structure, and is a Directory Record of files, where parameters include file name, file size, start position, and the like. When the system analyzes the ISO mirror image file, the initial position of the file is determined according to the Directory Record structure corresponding to the file, and the specific data of the file is read from the storage space corresponding to the initial position.
The size parameter and the initial position parameter in the Directory Record structure of the automatic answer file can be modified according to the file size and the initial position of the automatic answer file; and modifying the size parameter and the initial position parameter in the Directory Record structure of the Bootloader configuration file according to the file size and the initial position of the modified Bootloader configuration file.
According to the method for modifying the ISO mirror image file, the ISO mirror image file with the automatic response function can be obtained only by modifying the target ISO mirror image file, and the ISO mirror image file does not need to be packaged and manufactured again, so that the processing speed can be increased. Meanwhile, compared with the prior art, a temporary directory does not need to be generated, so that the storage space is saved.
The method for modifying an ISO image file provided by the embodiments of the present disclosure is further described below by taking an example of modifying an ISO image file in an ISO9660 format. As shown in fig. 2, the method comprises the steps of:
step S202, the target ISO mirror image file is analyzed.
In an ISO image file of ISO9660 format, the first 32KB bytes of content are typically system reserved areas. The content in the system reserved area of most ISO images is 0. Some information, such as ISO Hybrid function information, is recorded in a system reserved area of a small part of the ISO image file. This information is typically recorded in the first partial area (less than 10KB), and the contents of the remaining part of the system reserved area are all 0.
And analyzing the target ISO mirror image file to obtain the structure of the target ISO mirror image file. Fig. 3 shows a schematic structural diagram of a target ISO image obtained by parsing. As shown in fig. 3, the contents in the system reserved area (32KB) of the target ISO image are all 0, and there is no occupied area. The Bootloader configuration file in the target ISO image file includes an isolinux.cfg file and a grub.cfg file, and the two files are respectively used in different modes. Wherein the isilinux.cfg file is used in Legacy BIOS mode and grub.cfg file is used in UEFI mode. Png file in fig. 3 is a non-functional temporary file in the target ISO image file. The non-functional temporary files in the target ISO image file also include Release Notes, copyright description files, ISO description files, background picture files, and the like. In the target ISO image file, the Directory Record structure of the file and the specific data of the file may not be saved together, and the file size and the start position of the corresponding file are specified in the Directory Record structure.
Step S204, judging whether a system reserved area of the target ISO mirror image file has an occupied area; if yes, go to step S208, if no, go to step S206.
In order to avoid conflict of information coverage or storage space existing in the system reserved area when the auto-answer file is saved, whether the system reserved area has an occupied area or not can be judged from the analyzed target ISO image file. If the system reserved area has non-0 information, it indicates that the system reserved area has an occupied area, and if the system reserved area does not have the non-0 information, it indicates that the system reserved area does not have an occupied area.
Step S206 selects a first area and a second area from the system reserved area.
Step S208 selects a first zone and a second zone from the system reserved zone outside the occupied zone.
The first region and the second region may be selected from the entire system reserved area if no occupied region exists in the system reserved area of the target ISO image. If there is an occupied zone in the system reserved zone of the target ISO image file, the first zone and the second zone may be selected from the system reserved zone outside the occupied zone.
The first area is used for storing the automatic answer file, the size of the first area is a first designated value, and the first designated value is larger than or equal to the size of the automatic answer file. The second area is used for storing a Bootloader configuration file, and the size of the second area is a second designated value. If the Bootloader profile includes an isolinux.cfg file and a grub.cfg file, the second region may include a first sub-region for storing the isolinux.cfg file in the Bootloader profile and a second sub-region for storing the grub.cfg file. The size of the second specified value is greater than or equal to the sum of the sizes of the isilinux.cfg file and the grub.cfg file.
The order of selecting the first region and the second region is not limited, and the first region may be selected first and then the second region may be selected, the second region may be selected first and then the first region may be selected, or the first region and the second region may be selected at the same time.
For example, if the first 10KB of the system reserved area of the target ISO image file has non-0 information, the second 22KB of storage space of the system reserved area may be used to store the modified isilinux.cfg file, grub.cfg file, and the auto-answer file, wherein the isilinux.cfg file, grub.cfg file each occupy 2KB, and the auto-answer file occupies 18 KB. Under the condition of automatic installation, the isilinux.cfg file and the grub.cfg file are simple, each file only needs a few lines of codes, and the storage space of 2KB can ensure that the files are stored sufficiently. An auto-answer file typically includes about 100 lines of code, and 18KB of storage space may be sufficient to store the auto-answer file.
Step S210, storing the auto-answer file corresponding to the target ISO image file to the first area of the system reserved area of the target ISO image file.
And step S212, modifying the guide configuration file of the target ISO mirror image file according to the file name of the automatic response file.
In the ISO image file of ISO9660 format, the Directory Record structures have an organization relationship similar to a file tree, and it is simple to modify an existing Directory Record structure in an ISO image file, while it is difficult to newly add a Directory Record structure. For the target ISO mirror image file, the automatic response file is a new file, so a Directory Record structure needs to be added. It is very difficult to newly add a Directory Record structure, so that an existing Directory Record structure in the target ISO image file can be used as the Directory Record structure of the auto-answer file.
Considering that the target ISO image file contains non-functional temporary files, the temporary files are not used in the process of installing the operating system, and the installation of the operating system is not influenced by changing the Directory Record structure of the files. Therefore, the Directory Record structure of one temporary file can be designated as the Directory Record structure of the auto-answer file, and the file name of the designated temporary file can be designated as the file name of the auto-answer file. And adding access parameters corresponding to the file names in the Bootloader configuration file of the target ISO mirror image file. For example, a background picture file may be selected as the designated temporary file. The file name of the designated temporary file splash. The parameter ks ═ isolinux/splash. png is added in the isolinux.cfg file and in the grub.cfg file.
Step S214, storing the modified boot configuration file to a second area of the system reserved area.
Step S216, modifying the parameters in the corresponding Directory Record structure according to the file size and the initial position of the auto-answer file and the modified boot configuration file, so that the ISO mirror image file has an auto-answer function.
And modifying the size parameter and the starting position parameter in the Directory Record structure of the specified temporary file according to the file size and the starting position of the automatic response file. After modification, when the operating system is installed, the Directory Record structure will be guided to the automatic answer file, thereby completing the automatic installation of the system.
The size parameter and the starting position parameter in the Directory Record structure of the isolinux.cfg file are modified according to the file size and the starting position of the modified isolinux.cfg file.
And modifying the size parameter and the starting position parameter in the Directory Record structure of the grub.cfg file according to the file size and the starting position of the modified grub.cfg file.
Fig. 4 shows a structural diagram of a modified ISO image file, and as shown in fig. 4, the auto-answer file is stored in a first area of the reserved area of the system, which starts at 0x3200 and has a size of 10 KB. The automatic answering file uses the file name of the appointed temporary file splash.png, the Directory Record structure of the automatic answering file is the Directory Record structure of the original temporary file splash.png, the size parameter of the automatic answering file is modified to 10240, and the initial position parameter of the automatic answering file is modified to 0x 3200. Cfg file modified isolinux has a starting position of 0x2800 and a size of 1 KB. Cfg file modified to start at 0x3000 and size 1 KB. The original isolinux.cfg file, the original grub.cfg file and the original splash.png remain in place.
According to the method for modifying the ISO mirror image file, the ISO mirror image file with the automatic response function can be obtained only by modifying the target ISO mirror image file, and the ISO mirror image file does not need to be packaged and manufactured again, so that the processing speed can be increased. For example, the current ISO image for each operating system is close to 4GB in size, and some are even close to 8GB in size, in which case, if the ISO image with auto-answer function is made according to the existing method, it takes almost 10 minutes on a PC of ordinary configuration. According to the method for modifying the ISO mirror image file, the ISO mirror image file with the automatic response function is generated and can be completed within a few seconds.
Meanwhile, compared with the prior art, the method for modifying the ISO mirror image file provided by the embodiment of the disclosure does not need to generate a temporary directory, so that the storage space is saved. In addition, the modified ISO image file reserves the original Bootloader configuration file (namely the isolinux.cfg file and the grub.cfg file), and if the automatic installation function is not needed, the ISO image file can be restored as before.
