The method for realizing high availability of bare metal based on OpenStack according to claim 3, wherein the communication connection between the DHCP agent service and the agent service of the master bare metal node through the service network includes: the The DHCP agent service allocates a target IP address to the agent service in the main bare metal node according to the first request signal sent by the agent service of the main bare metal node, and records the Mac address of the main bare metal node, and The DHCP agent service realizes the communication connection with the agent service in the main bare metal node through the target IP address and the Mac address of the main bare metal node, wherein the first request signal includes the main bare metal node. The Mac address of the machine node. The method for implementing OpenStack-based bare metal high availability according to claim 1, wherein after starting the power supply of the backup bare metal node so that the backup bare metal node runs the operating system mapping file, further comprising: : The control node uses the Ironic conductor service to set the standby bare metal node that communicates with the DHCP agent service as a new primary bare metal node and selects another unused bare metal node as a new backup bare metal node node, and inject the operating system map file into the new standby bare metal node. The method for implementing OpenStack-based bare metal high availability according to claim 1, wherein the operating system mapping file includes an image file, an application program file and/or an operating system file. A device for realizing high availability of bare metal based on OpenStack, the improvement is that the device includes: Setting a module, setting one of the at least two bare metal nodes as the primary bare metal node, and setting the remaining bare metal nodes among the at least two bare metal nodes as the standby bare metal nodes, wherein the An operating system mapping file is injected into the primary bare metal node and the backup bare metal node; the communication module, the control node communicates with the primary bare metal node and the backup bare metal node through a power control network, and controls the primary bare metal node. The bare metal node is powered on so that the main bare metal node runs the operating system mapping file, and communicates with the main bare metal node through a service network; a state detection module controls the control node to receive the node status information sent by the master bare metal node, and when the node status information sent by the master bare metal node is not received, determine that the master bare metal node is working abnormally; and a control module, when it is determined that the master bare metal node When the work is abnormal, control to turn off the power of the main bare metal node, and start the power of the backup bare metal node to make the backup bare metal node run the operating system mapping file, wherein the control node includes a DHCP agent service and Ironic conductor service, the bare metal node includes an agent service and a power controller; the control node controls the power controller of the standby bare metal node to turn on the power through the Ironic conductor service; The DHCP agent service receives a second request signal requesting an IP address sent by the agent service of the standby bare metal node, and assigns a target IP address to the agent service of the standby bare metal node according to the second request signal and Recording the Mac address of the standby bare metal node so that the agent service of the standby bare metal node communicates with the DHCP agent service of the control node through the service network, wherein the second request signal Include the Mac address of the spare bare metal node. An electronic device, which is improved in that the electronic device includes a processor and a memory, and the processor is used to implement the OpenStack-based system according to any one of claim 1 to 6 when executing a computer program stored in the memory. The realization method of bare metal high availability.
