Kernel needed for System guides, initial system and operating system, Bootloader can be by boot partition 22 and operation
Unite subregion 23 on label, obtained from boot partition 22 and operating system partition 23 kernel, initial system and operating system with
The guidance to operating system is completed under different bootmodes.
The second embodiment of the present disclosure
The second embodiment of the present disclosure provides a kind of method for making and storing equipment 2 in first embodiment, referring to figure 3., this
Production method includes the following steps.
Storage equipment 2 is divided into multiple subregions by step S210, and plurality of subregion includes boot partition 21, starting point
Area 22 and operating system partition 23；
Boot partition 21 is written in first Bootloader by step S220；
Boot partition 22 is written in second Bootloader, kernel and first starting system by step S230；
Step S240, by operating system write operation system partitioning 23；
Step S250 is 23 configuration flag of boot partition 22 and operating system partition, so as to the first Bootloader and
Second Bootloader is according to the label lookup boot partition 22 and operating system partition 23, from boot partition 22 and operation system
System subregion 23 obtains kernel, first starting system and operating system for carrying out booting operating system.
Below by taking operating system CentOS6.8 as an example, the production method of above-mentioned storage equipment 2 is introduced.It will storage
Equipment 2 is divided at least three subregion, these subregions include boot partition 21, boot partition 22 and operating system partition 23.
The first Bootloader (such as EFI bootstrap) in guide management program grub2 is written to guidance point
In area 21；
Again by guide management program grub2 the second Bootloader (such as Legacy bootstrap), kernel and
First starting system (initramfs) is written to boot partition 22；
By operating system write operation system partitioning 23, in the embodiments of the present disclosure, operating system writing process be may is that
Firstly, by mounted operating system tool of compression (for example, tar) boil down to compressed package (for example, tar.gz)；Then, will
The compressed package unzips to the operating system after being cut under any one catalogue, main to delete such as (/usr/
The catalogues such as share/man/doc/help/vim)；Finally, by the operating system write operation system partitioning 23 after cutting.
It is boot partition 22 and the configuration of operating system partition 23 for the first Bootloader in guide management program grub2
With the label (label) of the second Bootloader identification, label is used to look on startup for identifying file partition
Look for boot partition 22 and operating system partition 23；And modify to the first Bootloader and the second Bootloader,
Set the first Bootloader and the second Bootloader in guide management program from storage by the label
Boot partition 22 or operating system partition 23 are searched in standby 2, so that the first Bootloader and the second Bootloader are logical
Cross the guidance of kernel, first starting system and operating system completion to operating system.Wherein, the first Bootloader is EFI guidance
Program or Legacy bootstrap, the second Bootloader are Legacy bootstrap or EFI bootstrap.
Further, have the function of data disks to make to store equipment 2, subregion further include under an operating system user it is visible
Visible partition 24, in the embodiments of the present disclosure, it is seen that the memory space that subregion 24 occupies storage equipment 2 is maximum.
The storage equipment making method that the embodiment of the present disclosure provides, is divided into multiple subregions by that will store equipment, not
With storage Bootloader, kernel, first starting system and operating system on subregion, and in storage kernel, first starting system and operation
The zone configuration of system marks, and calls above-mentioned resource according to label so as not to same Bootloader, realizes booting operating system.
The third embodiment of the present disclosure
