Host discovery and addition method and apparatus in data center, and device and medium

A method for discovering and adding a host in a data center, applied to to-be-added computing nodes in the data center, comprising:

• receiving a discovery message sent by a management node through IPv6 multicast after the to-be-added computing nodes are scanned by the management node, wherein virtualization systems or hyper-converged systems on the management node and the to-be-added computing nodes are factory-installed;
• verifying the discovery message, and sending, when the discovery message is successfully verified, discovery response messages corresponding to the discovery message through IPv6 unicast, so that when the discovery response messages are successfully verified and the to-be-added computing nodes are not configured with IP addresses, the management node sorts BMC IPs in the discovery response messages, and assigns IP addresses to the corresponding to-be-added computing nodes based on an order of the BMC IPs, enabling the IP addresses assigned to the to-be-added computing nodes corresponding to adjacent BMC IPs to be consecutive, wherein the IP addresses are IPv4 addresses;
• configuring a local network based on the IP addresses;
• and
• receiving an addition message sent by the management node, and sending addition response messages to the management node after the addition message is successfully verified, so that the management node adds the to-be-added computing nodes to the data center managed by the management node after receiving the addition response messages.

An electronic device, comprising:

• a memory and a processor,
• wherein the memory is configured to store a computer program;
• and
• the processor is configured to execute the computer program to implement operations of:
• scanning to-be-added computing nodes, wherein virtualization systems or hyper-converged systems on a management node and the to-be-added computing nodes are factory-installed:
• sending a discovery message to the scanned to-be-added computing nodes through IPv6 multicast, and receiving discovery response messages that are sent by the to-be-added computing nodes through IPv6 unicast after the discovery message being successfully verified by the to-be-added computing nodes;
• in response to determining that the discovery response messages have been successfully verified and the to-be-added computing nodes are not configured with IP addresses, sorting baseboard management controller (BMC) Internet protocols (IPs) in the discovery response messages, and assigning IP addresses to the corresponding to-be-added computing nodes based on an order of the BMC IPs, enabling the IP addresses assigned to the to-be-added computing nodes corresponding to adjacent BMC IPs to be consecutive, wherein the IP addresses are IPv4 addresses;
• and
• in response to determining that configuration of the IP addresses of the to-be-added computing nodes is completed, sending an addition message to the to-be-added computing nodes, receiving addition response messages returned by the to-be-added computing nodes after the addition message being successfully verified by the to-be-added computing nodes, and adding the to-be-added computing nodes to the data center managed by the management node.
