Specifically, for example, the distributed software may be classified into distributed data software, layered processing software, distributed network software, and the like, and the corresponding virtual management node may be selected according to different types of the distributed software.
Wherein the number of virtual management nodes allocated for distributed software may be plural. Preferably, one of the plurality of virtual management nodes is used as a main virtual management node (hereinafter, the main virtual management node is collectively referred to as a virtual management node), which can monitor the states of all the virtual nodes and provide a shared space to ensure the consistency of the nodes, and the remaining virtual management nodes are used as alternative virtual management nodes to prevent the backup virtual management node from being replaced as the main virtual management node when the main virtual management node cannot normally operate due to an abnormal condition.

Specifically, the determination may be performed by determining the correlation of the virtual management node, and specifically includes the following steps:
and D1, selecting the distributed virtual management node.
Wherein a plurality of virtual management nodes allocated for distributed software are selected.
Step D2: and reading the virtual management node of the historical allocation.

And if the number of the historically distributed virtual management nodes is larger than that of the distributed virtual management nodes, reducing the redundant number of the historically distributed virtual management nodes. And if the number of the historically distributed virtual management nodes is smaller than the number of the distributed virtual management nodes, reducing the redundant number of the distributed virtual management nodes.
And further, reducing the corresponding virtual management nodes according to the type of the distributed software corresponding to the virtual management nodes. And acquiring distributed software types corresponding to the historically distributed virtual management nodes and the distributed virtual management nodes respectively, and reducing the corresponding historically distributed virtual management nodes or the distributed virtual management nodes if the distributed software types corresponding to the historically distributed virtual management nodes and the distributed virtual management nodes are different or have overlarge difference.

wherein XiFor the performance value of the assigned virtual management node i,
n is the number of the selected distributed virtual management nodes and the historically distributed virtual management nodes; y isiThe performance value of the virtual management node allocated for the history,
average value of performance of the virtual management node allocated for the history.
If cov (X, Y) ≠ 0, it indicates that the selected assigned virtual management node has a correlation with the performance of the normal virtual management node in the history, and the virtual management node can continue to operate. Otherwise, selecting the corresponding virtual management node for the distributed software again.

When the distributed software receives the task requesting processing, the task is not executed immediately, but a task node is distributed to the task requesting processing according to the task requesting processing. Preferably, if a task requesting processing exists in the distributed software, a task node is allocated to the task, and if no task requesting processing exists, allocation waiting is performed.
Further, if a plurality of tasks requesting processing exist in the distributed software, task nodes are respectively allocated to the plurality of tasks, the plurality of tasks are divided, and the tasks are processed according to a certain sequence.
Furthermore, the tasks can be divided and processed according to the rules of the request time sequence, the response time and the like of the tasks.

Step S130: and the virtual management node records the state of the task information.
Specifically, the virtual management node records the task information as a starting state when the task node starts processing the task, and records the task information as a completion state when the task node completes the task of the distributed software, otherwise, records the task information as an abnormal state.
The task node processing task specifically comprises the following steps:
step P1: the task node requests the virtual management node to assign a process ID.
Step P2: the virtual management node returns the process ID to the task node and executes the task in the distributed software.

Step P4: and after responding to the success of the task processing of the task node, sending task information of the task to the virtual management node again, and receiving the task information and recording the task information as a completion state by the virtual management node.
Specifically, if the task node does not send the task information again within the specified time, the virtual management node records that the task information is in an abnormal state.
Step P5: and clearing the process ID of the task node in response to the completion of the recording of the task information by the virtual management node.
