in a specific embodiment, the process of selecting any node in the server cluster as the central node includes:
s21: establishing a first transmission channel based on any one of a DUBBO protocol, a TCP protocol and an HTTP protocol;
s22: collecting IP identity information and starting-up time of each node on any node in the server cluster through the first transmission channel;

S4: and carrying out communication between the central node and other nodes based on a communication protocol, so that other nodes obtain the value of the unique broadcast identification point of the central node according to preset time, and if the value of the unique broadcast identification point is verified with a preset threshold value in other nodes, executing a timing task.
Step S4 includes:
s41: setting threshold values on other nodes, selecting task nodes from the other nodes, and determining the number of nodes needing to execute tasks in the task nodes; the task node refers to a node by whom a task can be executed, but not all task nodes execute the task;
s42: enabling the central node to send the task data packet to the task node at preset time;
s43: and the sub identification point of the task node and the unique broadcast identification point of the central node carry out decryption operation, if the decryption is successful, the task node acquires the numerical value of the unique broadcast identification point of the central node and compares the numerical value of the unique broadcast identification point with the threshold value.
Specifically, the value of the threshold set on the other node and the value of the unique broadcast identification point of the central node are preset in advance, and the values are not limited specifically, and may be preset as two values, such as 0 and non-0, or may be preset as an array similar to 1, 2, and 3.
In one embodiment, if the value of the unique broadcast identification point is consistent with the value of the threshold, the execution of the task in the task data packet is abandoned; and if the sub identification value is not consistent with the threshold value, executing the task in the task data packet, and sending a task execution receipt to the central node, setting the threshold value and the unique broadcast identification point after the task is completed as non-0, setting the unique broadcast identification point before the task is completed as 0, if the value of the threshold value is not matched with the value of the unique broadcast identification point of the central node, namely the value of the unique broadcast identification point of the uncompleted task is 0, and the value of the threshold value is not 0, executing the timing task, and if the value of the threshold value is the same as the value of the unique broadcast identification point of the central node, namely the unique broadcast identification point after the task is completed is changed into non-0, and the value of the threshold value is 0, abandoning the task execution.
Specifically, in this embodiment, non-0 and 0 are used as the value of setting the threshold on other nodes and the initial value of the unique broadcast identification point of the central node, the task is a task of sending mails, which may be the same mail or two mails, taking the example that one mail must be sent at ten points as an example, in order to prevent unsuccessful sending, all three task nodes capable of sending mails are selected, because the network speed and the configuration of the three nodes are different, the time setting thereof has some deviation, when reaching ten points, the child identification point of the task node which reaches ten points first and the unique broadcast identification point of the central node perform decryption operation, when the decryption succeeds, the task node acquires the value of the unique broadcast identification point, if the value is 0, it executes the task of sending mails, and after the decryption, the task node sends a receipt back to the central node, then the value of the unique broadcast identification point is changed to be not 0, when another task node also reaches ten o' clock, the sub identification point of the another task node also carries out decryption operation with the unique broadcast identification point of the central node, when the decryption is successful, the another task node acquires the value of the unique broadcast identification point, at the moment, the unique broadcast identification point is already changed to be not 0, so that the threshold value which is stored in the another task node and is not 0 is consistent, the task is proved to be completed, and the task is not executed repeatedly.
In another embodiment, if the value of the unique broadcast identification point is consistent with the value of the threshold, executing the task in the task data packet; if the sub-identification value is not consistent with the threshold value, the task in the task data packet is abandoned, and the task execution receipt is sent to the central node, the method is more suitable for executing tasks by a plurality of task nodes, for example, if three task nodes are needed to complete the tasks, the threshold value can be preset to be 1, 2 and 3, when no task node completes the task, the value of the unique broadcast identification point is 1, when one task node completes the task, the value of the unique broadcast identification point is changed to be 2, when another task node completes the task, the value of the unique broadcast identification point is changed to be 3, therefore, when the value of the unique broadcast identification point is the same as the preset threshold value, the task can be executed, and so on, when the value of the unique broadcast identification point is 3, the task can be executed again, after the execution is completed, the value of the unique broadcast identification point is increased, if the value is not matched with the preset threshold value, the task is abandoned, which is not described herein.
Specifically, the server cluster related to the cluster calling method provided by the present invention may be each department server in an enterprise, each server in a hospital, or each server in a school, and no further description is given herein, in the above application scenario, a timing task may be executed based on the cluster calling method, first, any node is selected as a central node in the server cluster in the above scenario, a preset time is stored on the central node, then, a docking authentication mechanism is established, a unique broadcast identification point in the docking authentication mechanism is stored in the central node of the server cluster in the above scenario, a sub identification point matched with the unique broadcast identification point is stored in other nodes except the central node, then, the central node communicates with other nodes, so that the other nodes obtain a value of the unique broadcast identification point of the central node according to the preset time, if the value of the unique broadcast identification point is checked with the preset threshold value in the other nodes, executing the timing task in each scene, wherein the timing task can be any calling task to each node in the server cluster in the scene, can be a timing enterprise announcement sent to each node in an enterprise, can be a timing broadcast in a hospital for on-duty planning, or a timing conference plan sent in a school for real-time monitoring of the clusters in the scene, and can avoid the fact that one timing task is executed by a plurality of machines when the timing task is executed, thereby reducing the abnormal task execution condition.
