Step 401 when after startup of server, is set to PXE(Preboot Execute Environment, Pre-Boot eXecution Environment in BIOS) mode carries out netboot.
PXE works in Client/Server(client/server) network schemer, support performance station is downloaded reflection by network from far-end server, and support thus the start-up course of operating system of automatic network, in its start-up course, demanding terminal server-assignment IP address, use again TFTP(Trivial File Transfer Protocol, TFTP) or MTFTP(Multicast Trivial Tile Transfer Protocol, multiple spot TFTP) agreement downloads one and starts software package in the machine internal memory and carry out, completing terminal basic software by this startup software package arranges, thereby guiding is arranged on the terminal operating system in server in advance.
Step 402, server sends DHCP(Dynamic Host Configuration Protocol, DHCP) request, this DHCP carries the MAC Address of self in asking;
Step 403, because operation in boot manager has DHCP service routine, therefore accepts this DHCP request, and according to the IP address of this server and the corresponding relation of MAC Address, gives this server by the IP address assignment corresponding with the MAC Address of this server.For the virtual machine creating flow process shown in Fig. 2, this corresponding relation is set up in step 206; For the physical machine visioning procedure shown in Fig. 3, this corresponding relation is set up in step 304.
Step 404, server is accepted IP address and is configured by dhcp response, and passes through TFTP agreement from boot manager download system kernel file and initrd file; Boot manager, according to the MAC Address of this server, according to the MAC address of server of setting up before and the corresponding relation of system kernel file and initrd file, sends to this server by the system kernel file and the initrd file that generate for this server.For the virtual machine creating flow process shown in Fig. 2, this system kernel file and initrd file generate in step 206; For the physical machine visioning procedure shown in Fig. 3, this system kernel file and initrd file generate in step 304.
Step 405, the system kernel file loading system kernel that server basis is received, and carry out the initializtion script in initrd file, and the device drives of server is carried out to initialization, comprise the mirror image block device that initialization and connection server use.Owing to comprising SAN(Storage Area Network in initrd file, storage area network) driver and the configuration information of shared storage device, therefore boot kernel program according to this information the file system in can block device the loading blocks equipment at attended operation system image place.Resource Scheduler can be automatically according to driver and configuration information in the information updating initrd file of server.
Boot is according to the drive arrangements in the system image block device of this server of configuration information update of server and system setting, relevant system setting comprise file system configuration file, network profile etc. relevant to block device or with the relevant customized configurations such as distributed IP address.Here, if server is virtual machine, the driving kernel module of loading is configured to the driving that virtual machine is corresponding, if server is physical machine, the driving kernel module of loading is configured to the driving that physical equipment is corresponding.
Step 406 ~ 408, the file system in the system image block device that the system kernel carry of server is connected to, carries out root file system switching, is switched to the file system in system image block device, and continues executive system initialization flow process.
Step 409, server guides successfully.
For the boot flow shown in Fig. 4, it should be noted that, the agreement using in this flow process, such as DHCP agreement, TFTP agreement, be only the lower agreement that may use of a kind of concrete application scenarios, the embodiment of the present invention is not got rid of other agreement of use to reach same or similar object.
