Fig. 3 is a schematic flowchart of a method for automatically discovering a node, which is applied to a data center including a management platform and a plurality of nodes, where the management platform is used to manage the plurality of nodes, and as shown in fig. 3, the method includes:
after the data center system is started, the management platform can send the heartbeat packet based on a multicast protocol at regular time.
Specifically, a discovery device may be deployed on the management platform, the discovery device is accessed to the local area network, a discovery service is started, and the discovery device periodically sends a heartbeat packet based on a network multicast protocol.
after the nodes are deployed, the nodes are accessed to the local area network and then receive heartbeat packets sent by the management platform.
Specifically, an Agent (Agent) may be set in the node, and after the Agent is started along with the data center system, the Agent receives the heartbeat packet; and the Agent receiving the heartbeat packet judges whether an invalid identifier is stored locally.
When the invalid identifier is not locally saved, step 303 is executed, and when the invalid identifier is locally saved, step 311 is executed:
wherein, the response message carries the information of the node; the information of the node includes:
a serial number of the node, an operating system version of the node, a firmware version of the node.
when the information of the node is saved, step 305 and step 306 are executed, and when the information of the node is not saved, step 307 is executed:
specifically, the discovery device may receive a response packet of the node Agent, and determine whether the information of the node is stored in the invalid node repository.
The node information stored in the invalid node knowledge base is completely consistent with the node information carried in the response message. When the node that is determined to be an invalid node last time deletes the invalid identifier stored in the node after the version of the operating system is upgraded or the version of the firmware is upgraded, the received heartbeat packet is responded, and updated version information of the operating system or the firmware is carried in the response message, at this time, since the node information carried in the response message is inconsistent with the node information stored in the invalid node knowledge base, the node cannot be determined to be an invalid node, and step 307 can be executed. This ensures that when a node transitions from an invalid node to a valid node due to an operating system or firmware upgrade.
at this point, the process ends for the discovery of the node.
And the node stores the invalid identifier, so that the node does not respond when receiving the heartbeat packet again.
specifically, an auditing device may be deployed on the management platform, the discovery device receives a response message of the node Agent, determines whether the information of the node is stored in the invalid node knowledge base, and if not, sends the message to the auditing device, and the auditing device determines whether the node is of a type supported by the data center.
The type supported by the data center refers to the operating system version level or the firmware version level that the node needs to reach, for example, the operating system version level of the node that the management platform can require to manage is above centros 6.4.
When the node is a type supported by the data center, step 308 is executed, and when the node is not a type supported by the data center, steps 309 and 310 are executed:
wherein the judging whether the node is a type supported by the data center includes:
Judging whether the data center supports the operating system version of the node and the firmware version of the node;
when supported, determining that the node is of a type supported by the data center;
when not supported, determining that the node is not a type supported by the data center.
at this point, the process ends for the discovery of the node.
Specifically, a storage device may be deployed on the management platform, the auditing device determines whether the type is supported by the data center according to the received node information, and if so, the node information is sent to the storage device, and the storage device stores the node information after receiving the node information.
specifically, the auditing device judges whether the node information is of a type supported by the data center according to the received node information, if not, the node information is abandoned and stored in the invalid node knowledge base.
at this point, the process ends for the discovery of the node.
And when the node receives the heartbeat packet again, the node does not respond to the heartbeat packet any more.
In step 311, the node does not respond to the heartbeat packet.
The technical solution provided by this embodiment automatically discovers node devices in a data center based on a multicast protocol. After the data center equipment is changed, the data center equipment can be found by the management platform in time, the workload of manual maintenance is effectively reduced, and the working efficiency is improved.
In another embodiment of the present invention, the difference from the previous embodiment is that the invalid node knowledge base stores the identities of invalid nodes, and the identity of a node is an identity generated by the serial number, operating system version, and firmware version of the node using an existing identity generation algorithm. When the management platform receives the response message of the heartbeat packet, the serial number, the operating system version and the firmware version carried in the response message are extracted, the corresponding identification is generated by applying the same identification generation algorithm, and then whether the identification is stored in the invalid node knowledge base or not is judged. Therefore, after the operating system version or the firmware version of the node is upgraded, the generated identifiers are different, the node cannot be directly judged as an invalid node, and the subsequent steps can be executed. This ensures that when a node transitions from an invalid node to a valid node due to an operating system or firmware upgrade.
