Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Pxe the installation process can be split into dhcp (Dynamic Host Configuration Protocol) service, tftp (simple File Transfer Protocol) and http (HyperText Transfer Protocol) service. Firstly, the cloud host sends out a dhcp request to a host (also called an installation server) to request an internet protocol address IP address, and the dhcp service allocates the IP address and tells subsequent tftp and http service addresses. After the cloud host acquires the address, the cloud host accesses an installation server (possibly different from the installation server) through tftp to download a starting mirror image, and downloads an installation mirror image through http service to start and install the system.
However, there is a problem in that the cloud host, that is, the virtual network card of the physical machine, is connected to the openvswitch bridge of the host and then sent out from the physical network card through the tunnel port. In the mode, the physical network port of the host and the virtual network port of the cloud host are not on the same two layers, so that the cloud host cannot be installed through the PXE.
In order to solve the above problem, an embodiment of the present invention provides a data acquisition method, which is applied to a cloud host, and with reference to fig. 1, the data acquisition method includes:
s11, sending the dhcp request for requesting the IP address.
In this embodiment, the cloud host, which may also be referred to as a physical machine, is in a bare machine state before the PXE installation, and at this time, the cloud host needs to acquire data required by the installation and perform the PXE installation operation.
First, the cloud host sends a dhcp request, which is used to request an IP address for the cloud host.
And S12, receiving the VPC address and the public service address which are received by the intelligent network card corresponding to the cloud host and fed back to the dhcp request.
The embodiment splits the acquired installed data into two parts of dhcp based on two-layer forwarding and TFTP and http based on three-layer forwarding. Specifically, the intelligent network card corresponding to the cloud host, that is, the host, receives the dhcp request and assigns a vpc address to the cloud host by replying the dhcp request instead, and specifies a tftp public service address and an http public service address. It is assigned a vpc address because only the vpc address has access to the public service. Wherein the public service address comprises the tftp public service address and the http public service address; the installed image file comprises a boot image and an installation image.
And the host machine using the public service address stores an installed image file, and the physical machine and the cloud host belong to the same local area network. I.e., Tftp and http services are deployed to public services. And the cloud host accesses the tftp and http services through the public service. The physical machine used by the public service and the cloud host belong to the same user network, and the same network can be accessed mutually.
And S13, accessing the physical machine by using the VPC address to acquire the installed image file.
In practical application, the VPC address is used for accessing the tftp public service address of the physical machine to obtain the boot image, and the VPC address is used for accessing the http public service address of the physical machine to obtain the installation image. That is, the installed image file is available through a physical machine having a public service.
And S14, performing installation operation based on the installation image file.
After the starting mirror image and the installation mirror image are obtained, system starting and installation can be carried out so as to guarantee normal work of the cloud host.
In this embodiment, a cloud host sends a dhcp request for requesting an IP address, an intelligent network card corresponding to the cloud host receives the dhcp request and feeds back a VPC address and a public service address to the dhcp request, where a physical machine using the public service address stores an installed image file, the physical machine and the cloud host belong to the same local area network, the VPC address is used to access the physical machine to obtain the installed image file, and an installation operation is performed based on the installed image file. Because the physical machine and the cloud host belong to the same local area network, the problem that the physical machine and the cloud host do not belong to the same layer network does not exist during communication, and the installed image file of the physical machine can be accessed to perform installation operation.
In another implementation manner of the present invention, a data acquisition method is provided, which is applied to an intelligent network card, and the data acquisition method includes:
acquiring a dhcp request which is sent by a cloud host and used for requesting an IP address of an Internet protocol address;
