The embodiment is applicable to bare metal deployment, and the method can be executed by a cloud environment platform and specifically comprises the following steps:
Step S110, after receiving a DHCP request sent by the target bare machine under the deployment network, the dynamic host configuration protocol DHCP service module sends first feedback information to the target bare machine.
In this embodiment, the DHCP service module may be integrated in the cloud environment platform in the form of a component, where the DHCP request may be understood as a request from the target bare computer to allocate an internet protocol address and request information of the initial image file. The target bare machine can be understood as a bare machine with installation and deployment requirements; a deployment network may be understood as a network to which a pre-specified bare metal needs to be connected. The first feedback information can be understood as information which is correspondingly fed back according to the DHCP request, and the first feedback information comprises a network address of a TFTP server, an initial mirror image file name and a bare computer Internet protocol address; the TFTP server is a server that implements TFTP service functions. The initial image file name may be understood as the name of the initial image file, and is used to instruct the target bare machine what kind of image file is obtained from the simple transport protocol service module. Bare metal internet protocol addresses may be understood as internet protocol addresses assigned to the target bare metal.
After the target bare machine is started, a DHCP request is generated, the DHCP request is sent to a DHCP service module through a deployment network, after the DHCP request is received, the DHCP service module determines the content requested by the target bare machine according to the DHCP request, generates corresponding first feedback information, and then feeds back the first feedback information to the target bare machine.

And step S120, after receiving the initial mirror image request sent by the target bare machine according to the first feedback information, the TFTP service module sends an initial mirror image file to the target bare machine.
In this embodiment, the initial mirror request is determined and sent by the target bare metal according to the first feedback information. The TFTP service module can be integrated in the cloud environment platform in a component mode, and further provides TFTP services for an Ironic component of the cloud environment platform OpenStack. An initial image request may be understood as a request for obtaining an initial image file, which is used to obtain an image file of a boot loader, and the image file is similar to a compressed package, and a specific series of files are made into a single file according to a certain format, so as to facilitate the downloading and use of users, such as an operating system, a game, etc. of a test version. boot loader is a functionally simple operating system that is used to install the necessary drivers, tools, and bare metal proxy services. The initial image file may be understood as an image file of a boot loader.
The target bare machine correspondingly generates an initial mirror image request according to which file is acquired and indicated in the first feedback information, takes a bare machine Internet protocol address in the first feedback information as an own IP address, and sends the initial mirror image request to the TFTP service module, wherein the initial mirror image request can carry an initial mirror image file name so that the TFTP service module can determine the initial mirror image file, the TFTP service module determines the initial mirror image file according to the initial mirror image request after receiving the initial mirror image request, and then sends the initial mirror image file to the target bare machine, and the target bare machine installs proxy service according to the initial mirror image file. The TFTP service module may determine the name of the initial image file according to the initial image request, and use the file matching the name of the initial image file as the initial image file.

The method comprises the steps that a target bare machine realizes communication with a cloud environment platform through corresponding switch ports, each switch port is provided with a unique virtual local area network address vlan IP, a network control module adjusts the virtual local area network address of the switch port corresponding to the target bare machine into a tenant network, and meanwhile, a service network transmission channel between the switch port corresponding to the target bare machine and an Internet protocol address of the cloud environment platform is established, so that service network communication between the target bare machine and the cloud environment platform is realized, and a proxy service installed by the target bare machine sends a DHCP request to a DHCP service module through the service network transmission channel. The service network transmission channel is a data transmission channel between a virtual local area network address of a switch port corresponding to the target bare machine (the virtual network address of the switch port corresponding to the target bare machine at this time is a tenant network) and an internet protocol address of the cloud environment platform.
Step S140, after receiving a DHCP request sent by a proxy service installed on the target bare machine under a tenant network, the DHCP service module sends second feedback information to the target bare machine; and the proxy service is a service installed after the initial image file is started for the target bare machine.
In this embodiment, the second feedback information may be understood as feedback information generated by the DHCP service module according to a DHCP request sent by the proxy service under the tenant network, and further, the second feedback information includes a tenant network address.
After the proxy service is installed on the target bare machine, the virtual network address of the corresponding switch port is the tenant network, a service network transmission channel established by the network control module under the tenant network sends a DHCP request to the DHCP service module, and after receiving the DHCP request, the DHCP service module selects an IP address from the tenant network as second feedback information and feeds the second feedback information back to the target bare machine. After receiving the second feedback information, the target bare machine determines its own IP address according to the second feedback information for subsequent service network communication.
And step S150, after receiving the formal image request sent by the target bare machine based on the second feedback information, the image service management module sends a formal image file to the target bare machine so as to enable the target bare machine to be installed to realize installation and deployment.

The formal image request can be understood as a request for acquiring a formal image file required for installing the deployment system; the formal image file may be understood as an image file required for the target bare metal installation deployment.
The target bare machine sends a formal image request to the image service management module through the second feedback information, the image service management module determines a corresponding formal image file after receiving the formal image request, and then sends the formal image file to the target bare machine, and the target bare machine performs system installation and deployment according to the formal image file.

In this embodiment, the bare metal management module may be understood as a module for managing bare metal, and may be integrated as a component in a cloud computing management platform, and further, the bare metal management module is an Ironic-conductor component of the cloud environment platform OpenStack. The screening condition may be a condition input by a user on the interface, or a plurality of types of limiting conditions are set on the interface in advance, each type of limiting condition is set as a plurality of choices, the user only needs to select through clicking, and a corresponding screening condition is generated according to the selection of the user, for example, the user manually inputs an 8-core CPU (Central processing Unit), 64g of memory, and 8-core CPU and 64g of memory are used as screening conditions to screen each bare machine, or a selection item corresponding to the CPU and a selection item corresponding to the memory are set on the interface, and the user only needs to click the selection item to form the screening condition. Screening the plurality of bare computers according to the screening conditions to obtain target bare computers meeting the conditions, randomly selecting one bare computer from the plurality of bare computers meeting the screening conditions to serve as the target bare computer if the plurality of bare computers meet the screening conditions, or screening the target bare computers again according to other basic information of the bare computers to obtain the target bare computer, or displaying the bare computers meeting the screening conditions to a user through an interface, and selecting the target bare computer by the user. When screening the bare computers, the basic information of each bare computer needs to be input in advance, and the basic information can be the size of a CPU, the size of a memory and the like. The bare machine management module sends a starting instruction to the target bare machine through an intelligent platform management interface (IPMI interface) of the target bare machine, and controls a power key of the target bare machine to power up so as to realize the starting of the target bare machine.
The corresponding relation between the bare machine and the switch port is established through the network control module, so that the bare machine can communicate through the switch port, and the target bare machine can be obtained by screening the bare machine, so that the target bare machine does not need to be manually selected, and the method is more convenient and quicker.
