[0056] Embodiment 1

[0057] Figure 1 A flowchart of an operating system migration method provided in the first embodiment of the present application is provided, and the method is applicable to the case of rapid migration of the operating system. The method can be executed by a server.

[0058] like Figure 1 As shown, the first embodiment provides an operating system migration method, which specifically includes the following steps:

[0059] S101, determining a target disk corresponding to a target machine.

[0060] In this embodiment, the target machine can be specifically understood as a system machine created on a cloud computing platform. The target disk can be specifically understood as a disk of the target machine, which is used to store data of the target machine.

[0061] Specifically, when performing operating system migration, first determine the source machine to be migrated, that is, the machine to be migrated. Create a target machine on the cloud computing platform based on the configuration information of the source machine to be migrated, so that the target machine can work instead of the source machine to be migrated. After the target machine is created, allocate resources and a target disk to the target machine, and establish a connection between the target machine and the target disk. After the target machine is determined, the target disk of the target machine is determined accordingly.

[0062] As an optional embodiment of the present embodiment, the optional embodiment is further optimized to include: the size of the target disk is determined according to the size of the disk of the source machine to be migrated.

[0063] When allocating disks to the target machine, determine the disk size of the source machine to be migrated and allocate a target disk of the same size to the target machine.

[0064] As an optional embodiment of the present embodiment, the optional embodiment is further optimized to include: the resource configuration information of the target machine is determined according to the source machine to be migrated, and the resource configuration information includes at least one or more of the following information: central processing unit information, memory information, disk information, and network card information.

[0065] In this embodiment, the resource configuration information can be specifically understood as the relevant information of the working environment when the target machine starts working or works normally. Since the target machine is a copy of the source machine to be migrated, the resource configuration information of the target machine is the same as the resource configuration information of the source machine to be migrated. The resource configuration information of the source machine to be migrated is obtained in advance, and the target machine is configured according to the resource configuration information of the source machine to be migrated.

[0066] Exemplarily, the present application provides a method for obtaining resource configuration information, and obtains the following information from the source system to be migrated through system commands:

[0067] 1. Central Processing Unit CPU Information

[0068]

[0069] 2. Memory information

[0070] root@from#cat / proc / meminfo

[0071] MemTotal: 7990124kB

[0072] 3. Network card information (single network card)

[0073]

[0074] 4. Disk (hard disk) information

[0075]

[0076] You can also get the motherboard information through the following code

[0077] root@from#[-d / sys / firmware / efi]&&echo “Installed in UEFI mode”||echo “Installed in Legacy mode”

[0078] “Installed in Legacy mode”

[0079] Exemplarily, the configuration of the target machine created in the embodiment of the present application is BIOS, 1 CPU, 1 network card, and 1 disk.

[0080] S102: Writing data to the target disk according to the source machine to be migrated corresponding to the target machine.

[0081] Specifically, the source machine to be migrated has a corresponding disk, and the disk contains relevant information of the source machine to be migrated, such as configuration information, operation information, etc. The source machine to be migrated corresponding to the target machine is determined, and the data in the disk of the source machine to be migrated is further determined, and the data in the disk of the source machine to be migrated is copied and written to the target disk, thereby completing the data writing of the target machine.

[0082] S103, modifying the boot information of the target machine to the target disk to achieve operating system migration.

[0083] Specifically, the boot information of the target machine points to the host of the cloud computing platform, and the target machine cannot start its own system after startup. Directly modify the boot information of the target machine so that the boot information of the target machine points to the target disk allocated for the target machine. After modifying the boot information of the target machine to the target disk, the target machine can boot the system through the boot information after startup, complete the system startup, and then realize the migration of the operating system.

[0084] The embodiment of the present invention provides an operating system migration method, which realizes operating system migration by determining a target disk corresponding to a target machine; writing data to the target disk according to a source machine to be migrated corresponding to the target machine; and modifying the boot information of the target machine to the target disk. The method solves the problem of complex operation during operating system migration, completes disk data replication by writing data to the target disk of the target machine, and makes the boot information of the target machine point to the target disk by modifying the boot information of the target machine, so that after the target machine is started, the system can be booted and started according to the information of the target disk, thereby realizing operating system migration. After creating a target machine on a cloud computing platform, it is only necessary to write data to the target disk and modify the boot information of the target machine to realize operating system migration. The implementation process is simple and convenient, and there is no need to establish an additional transfer machine, so that the migration of the operating system can be completed efficiently.

[0085] Embodiment 2

[0086] Figure 2 This is a flow chart of an operating system migration method provided in Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above technical solution, and specifically mainly includes the following steps:

[0087] S201, determining the target disk corresponding to the target machine.

[0088] S202. Configure the network address of the target machine.

[0089] If the target machine needs to access an external server or computer device during normal operation, it needs to configure a network address before accessing it. For example, the network address of the target machine is set to 172.20.7.10.

[0090] S203: Establish a network connection between the target machine and the source machine to be migrated according to the network addresses of the target machine and the source machine to be migrated.

[0091] The network address of the source machine to be migrated is pre-configured. When the source machine to be migrated is determined, its network address is determined accordingly. A network connection between the target machine and the source machine to be migrated is established according to the network address of the target machine and the network address of the source machine to be migrated to achieve network communication. The target machine in this application needs to copy data from the disk of the source machine to be migrated to achieve data backup. Copying data from the source machine to be migrated requires the target machine to access the source machine to be migrated. Therefore, a network connection between the target machine and the source machine to be migrated is established to achieve network communication.

[0092] S204: Enter the source machine to be migrated according to the system boot of the source machine to be migrated.

[0093] In this embodiment, system boot refers to the process of loading the operating system kernel into memory and starting the system. System boot is usually completed by a special code called a boot program, which is located in the system ROM and is used to complete the entire system boot process of locating the specific location of the kernel code in the external memory, correctly loading the kernel into the memory as required, and finally making the kernel run. In this process, the boot program must complete multiple initialization processes, and various services of the system can only be used after these processes are successfully completed. These processes include initial boot, kernel initialization, and full system initialization. The operating system of each computer has a system boot, so that the computer completes the startup process and enters the source machine to be migrated through the recovery system boot of the source machine to be migrated. After entering the source machine to be migrated, the IP address of the source machine to be migrated can be reset, or the original IP address of the source machine to be migrated can be used. The embodiment of the present application sets the IP address of the source machine to be migrated to 172.20.7.11.

[0094] S205 . Copy the disk data of the source machine to be migrated according to the preset read and write commands, and write the copied disk data into the target disk according to the network connection between the source machine to be migrated and the target machine.

[0095] In this embodiment, the read and write commands can be specifically understood as pre-set operation commands, which can read and write data. Preferably, the read and write commands of the present application are dd commands, which copy a file by using blocks of a specified size and perform specified conversions while copying.

[0096] Specifically, the command type of the read and write command is pre-set, and the corresponding read and write command is determined according to the specific read and write operations. For example, the dd command corresponding to backing up the local / dev / hdb disk to / dev / hdd is: dd if= / dev / hdb of= / dev / hdd. The data in the disk of the source machine to be migrated is copied through the preset read and write commands, and the copied data is written to the target disk according to the network connection between the source machine to be migrated and the target machine, so as to realize the data backup of the target disk of the target machine.

[0097] Exemplarily, an embodiment of the present application provides an implementation code for copying disk data of a source machine to be migrated and writing the data to a target disk through a preset read and write command:

[0098] root@to#nc–v–l–p 2000|gzip–cd> / dev / sdb

[0099] root@from#dd if= / dev / sda bs=512count=41943040|gzip–c9|nc–q 2172.20.7.10 2000

[0100] The root@to code means opening port 2000, which is waiting to write data to the target disk of the target machine. The root@from code means copying data from the disk (dev / sda) of the source machine to be migrated and sending it to the target disk of the target machine through port 2000.

[0101] S206: Determine the source pointing address of the boot information of the target machine and the target address of the target disk.

[0102] In this embodiment, the boot information can be specifically understood as information for selecting an operating system to be run when the computer is started. Multiple operating systems can be installed on the computer at the same time. In this case, the system to be run will be selected when the computer is started, and the system to be run after the computer is started is selected through the boot information. The source pointing address can be specifically understood as the address pointed to by the boot information after the target machine is created. The source pointing address is usually the default address after the target machine is created. The source pointing address of the boot information of the target machine is determined by analyzing the boot information of the target machine. When allocating the target disk, the target address corresponding to the target disk is determined accordingly.

[0103] S207: Replace the source pointing address in the boot information according to the target address, so that the boot information points to the target disk.

[0104] Replace the source address in the boot information with the target address. At this time, the boot information points to the target disk accordingly. That is, after the target machine is started, the boot information will guide the system to start according to the data in the target disk.

[0105] Exemplarily, the boot information in this application is grub boot information. grub is a multi-operating system boot program from the GNU project. grub is an implementation of the multi-boot specification, allowing users to have multiple operating systems in a computer at the same time and select the operating system they want to run when the computer starts. grub can be used to select different kernels on the operating system partition, and can also be used to pass boot parameters to these kernels.

[0106] S208. Restart the target machine.

[0107] Shut down and restart the target machine. Restart can be achieved through system operation commands, keystrokes, disconnecting the power supply and then powering it back on.

[0108] S209: Determine the driver to be installed corresponding to the target machine.

[0109] In this embodiment, the driver to be installed can be specifically understood as the driver that needs to be installed for the target machine to operate normally on the cloud computing platform. The driver is a configuration file written by the hardware manufacturer according to the operating system. Without the driver, the hardware in the computer cannot work. Different operating systems have different hardware drivers. The driver to be installed required for the target machine to work on the cloud computing platform is determined based on the corresponding hardware devices of the cloud computing platform and the operating system of the target machine. The number of drivers to be installed in this application can be one or more.

[0110] S210. Install the driver to be installed on the system of the target machine.

[0111] Install all drivers to be installed on the target machine's system. After installing the drivers to be installed corresponding to the cloud computing platform on the target machine's system, the migration of the operating system is now complete.

[0112] For example, Figure 3 An implementation example diagram of the migration of a source machine to be migrated is provided. A target machine 31 is created on a cloud computing platform 30. The source machine 32 to be migrated takes the Linux operating system as an example. The target machine 31 copies data to the source machine 32 to be migrated through the Recover boot system.

[0113] The embodiment of the present invention provides an operating system migration method, which realizes operating system migration by determining a target disk corresponding to a target machine; writing data to the target disk according to a source machine to be migrated corresponding to the target machine; and modifying the boot information of the target machine to the target disk. The problem of complex operation during operating system migration is solved, and the disk data of the source machine to be migrated is copied and written to the target disk of the target machine through a preset read and write command, thereby realizing fast and efficient copying of disk data. By modifying the boot information of the target machine, the boot information of the target machine points to the target disk, so that the target machine can boot and start the system according to the information of the target disk after startup, thereby realizing fast migration of the operating system, and the operation is simple. After creating a target machine on a cloud computing platform, it is only necessary to write data to the target disk and modify the boot information of the target machine to realize the migration of the operating system. The implementation process is simple and convenient, and there is no need to establish an additional transfer machine, so that the migration of the operating system can be completed efficiently.
