Specifically, each node is a server, each server includes a data synchronization module and an application layer module, the application layer module is configured to acquire data to be synchronized or initiate a request for synchronizing the data, and the data synchronization module is configured to send the data acquired by the application layer module. The designated node may be all nodes except the triggering preset condition, or may be one or more nodes except the triggering preset condition. The shared hardware resource data refers to management and control data of the server, such as temperature, voltage, manufacturer, system version, power supply and other information of the server.

And the stability of data synchronization among multiple nodes is ensured by initiating data synchronization for multiple times.
In some embodiments, the method further comprises: and responding to the failure times larger than the preset times, the node generates an alarm state and synchronizes the alarm state to other nodes in the management platform.
In some embodiments, the method further comprises: monitoring the connection state among the nodes through heartbeat, and clearing the synchronization marks and the shared hardware resource data of the corresponding nodes in response to the loss of the heartbeat state among the nodes.

In some embodiments, the method further comprises: and monitoring the in-place state of the node, and clearing the synchronization mark and the shared hardware resource data of the corresponding node in response to the node not being in place.
The in-place state, namely whether the nodes are in the slot positions or not, is monitored, the nodes which are not in place can be found by monitoring the in-place state of each node, and data synchronization is carried out in time after the slot positions are inserted again among the nodes, so that the consistency of data among the nodes is ensured, and the stability of the server is improved.
In some embodiments, the trigger preset condition comprises: and the node is any one of reset starting, power-on starting and synchronization failure.
Several embodiments of the present invention are described below with reference to specific examples.
Assume that 4 server nodes in the current server management platform are interconnected to form an operating system, and the interconnection diagram of the 4 nodes is shown in fig. 3.
The node 1 is just reset and started, after the node 1 is reset, an application layer module of the node 1 initiates a data request command, and the data request command is distributed to all nodes (except the node 2/3/4) in a frame in a broadcast mode through a data synchronization module of the node 1;
after receiving the data request command, the data synchronization module of the node 2/3/4 transmits the received request command to the application layer module, and after receiving the command, the application layer module of the node 2/3/4 starts to acquire respective shared hardware resource data and synchronizes to the node 1 through the respective data synchronization module after acquiring the shared hardware resource data;
after receiving the shared hardware resource data synchronized by the node 2/3/4, the node 1 checks whether it stores data synchronized by other nodes. If the node 1 stores the data synchronized by the node 2/3/4, sending a completion flag to the node 2/3/4, exiting the check, and waiting for the next trigger detection; if data synchronized by one or more nodes is missing, for example, the shared hardware resource data of the node 2 is missing, it indicates that synchronization is not completed and the shared hardware resource data of the node 2 fails to be synchronized.
The node 1 initiates a data request command to the node 2 separately, repeats the above process, and if the data synchronization still fails after initiating the data synchronization for many times, the node 1 generates an alarm state and synchronizes the alarm state to the node 3/4.
Further, after the node 1 generates the alarm, the node continues to reinitiate synchronization to the node 2, and attempts to repair. And if the repair is successful, eliminating the alarm state and recording the alarm state to a log so as to increase the stability of data synchronization. If the attempt fails for a plurality of times, reporting the system and disconnecting the node 2.
Furthermore, if a restart or node plugging or upgrading scenario occurs in any node due to the stability of the heartbeat or on-site state detection node 1/2/3/4 in the operation process, the synchronization flag of the node is lost and the corresponding shared hardware resource data is cleared by detecting the heartbeat state, or the synchronization flag is cleared and the corresponding shared hardware resource data is cleared by the off-site state of the node. And after the node works normally, restarting the data synchronization of the shared hardware resource.
Through the scheme, data synchronization can be performed between a plurality of nodes at will, and particularly when a server needs to provide service support for a service scene in a data state of a management system, it is particularly important that data of other nodes exist at any node, for example, the management system provides key shared hardware resource data, and the key data determines the establishment and service use of a cluster. The server needs to acquire the data in the starting process to ensure correct starting and the system can provide services to the outside.
