Detailed Description
The present invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
In order to overcome the above existing defects, this embodiment provides a clustering method for data communication, where the clustering method includes the following steps:
sequencing N nodes of all clusters, and sequentially editing a logic address to respectively form nodes with a first logic address to an Nth logic address, wherein N is a natural number greater than 1;
setting the node with the minimum serial number logical address as a main node, and setting other nodes as slave nodes respectively, wherein the main node broadcasts a heartbeat message containing the own logical address to the other slave nodes according to a preset time interval;
and responding to the abnormal or downtime of the main node to stop broadcasting the heartbeat message, setting the nodes with the minimum serial number logical addresses except the main node as the current main node for taking over the work of the previous main node, setting the other nodes as slave nodes respectively, and broadcasting the heartbeat message containing the own logical address to the other nodes by the current main node according to a preset time interval.
Preferably, as an embodiment, the step of ordering the N nodes of all the clusters includes the following steps:
and sequencing the N nodes of all the clusters from high to low according to the hardware configuration indexes of the nodes.
Specifically, as an embodiment, after the current master node is set, the clustering method further includes the following steps:
responding to the restart of the previous node stopping broadcasting, judging whether the logic address of the previous node is smaller than that of the current main node or not, if so, resetting the current main node of the previous node to be restarted, setting the other nodes as slave nodes respectively, and broadcasting the heartbeat message containing the logic address of the current main node to the other nodes by the current main node according to a preset time interval.
Preferably, as an embodiment, the clustering method further includes the steps of:
and when the number of the restarted previous nodes is at least two and the logical addresses of all the restarted previous nodes are smaller than the logical address of the current main node, selecting the node with the smallest logical address from all the restarted previous nodes and resetting the node as the current main node.
In the embodiment, the scheme that the clustering is quickly and conveniently realized when high availability or server clustering is required under the application of internet big data is mainly involved, the simplification idea is fully utilized, the requirements on hardware and software performance are extremely low, and the mode of providing the clustering in the single chip microcomputer system can be completely realized.
Specifically, the following describes a specific flow of the clustering method with reference to the drawings.
Referring to fig. 1, in this embodiment, based on the idea of token ring, all cluster nodes edit one logical address (1, 2, 3 … N), that is, a token, and node No. 1 (i.e., a node with a first logical address) is a default master node and is also a node with a relatively high configuration. One node is always kept as a master node in the whole cluster, and a node with a first logical address is set as the master node under normal conditions and broadcasts a survival heartbeat to other slave nodes at regular time (the heartbeat message contains the master node address).
Referring to fig. 2, when first started, a node having a first logical address is set as a master node by default and broadcasts a heartbeat message.
Referring to fig. 3 and 4, once the master node is abnormal or goes down to stop broadcasting the heartbeat, the token is invalid, and a new token is generated, and the new token may be delivered by: the new token is the home node address + 1. The new token owner continues to broadcast the heartbeat message containing the own logical address for the new host node, and so on until the token is lost, all nodes broadcast the heartbeat outwards, each node receives all the surviving node addresses, and the node with the smallest logical address can be elected as the host node (the node address is the token at this time) through simple election processing, so that the host node is continuously taken over to work and the heartbeat message is continuously broadcast. Therefore, the clustering process is circulated all the time, and the clustering can be carried out without the limitation of the number of nodes as long as the survival node services are available.
Referring to fig. 5 and 6, when the master node with the second logical address goes down, the master node with the second logical address stops broadcasting, all nodes live and wait for a period of time, and after a period of time, no heartbeat is received, the live nodes send broadcast elections, and confirm that the node with the smallest logical address is set as the new master node, and the node with the third logical address is also found to go down in fig. 5 and 6, so the node with the fourth logical address is set as the master node.
Referring to fig. 7 and 8, when a node having a smaller logical address than the current master node is restarted, a heartbeat is automatically broadcasted, all nodes that receive a heartbeat packet having a smaller logical address than the current master node immediately stop broadcasting and change into slave nodes, and after the node having the first logical address in fig. 7 and 8 is restarted and recovered, the node becomes a new master node, and the original master node (i.e., the master node having the fourth logical address) becomes a slave node.
The following describes an application of the clustering method.
The first step is as follows: selecting a service system or a device needing the cluster, such as: an anodic oxidation data acquisition system, an edge computing box device, and the like, which are not particularly limited to a cluster service system or device in this embodiment, and can be selected and adjusted accordingly according to actual needs.
The second step is that: based on the above system or apparatus, the upgrade code implements a clustering function.
The third step: n servers or devices having the same logical function, that is, nodes, are prepared, and the edited logical addresses 1, 2, and 3 … N, that is, the first logical address and the nth logical address of the second logical address …, are configured at the same time. Relevant information (IP (internet protocol), port, logical address, etc.) is configured in all node configurations for use by heartbeat broadcasts.
The fourth step: the start service loads the cluster configuration information, and then the cluster can be easily realized according to a set mode.
The clustering method for data communication provided by the embodiment can fully respond to various application scenes needing master-slave switching or clustering, simply, quickly and conveniently realize clustering, effectively reduces the requirements on hardware and software performance, and effectively realizes a clustering mode provided in a single chip microcomputer system, thereby improving the realizability and the operability, and further improving the stability and the reliability.

The node management module 1 is configured to sort N nodes of all clusters, and sequentially edit one logical address to form nodes having first to nth logical addresses, respectively, where N is a natural number greater than 1.
Preferably, as an embodiment, the node management module 1 is configured to sort the N nodes of all the clusters according to the order of the hardware configuration indexes of the nodes from high to low.
The node setting module 2 is configured to set the node with the smallest sequence number logical address as a master node, and set the remaining nodes as slave nodes, respectively, and the master node broadcasts a heartbeat message including its own logical address to the remaining slave nodes according to a preset time interval.
The node monitoring module 3 is configured to monitor a broadcast state of the main node, respond to an exception or downtime generated by the main node to stop broadcasting the heartbeat message, and invoke the node setting module 2 to set the node with the smallest sequence number logical address except the main node as a current main node for taking over the previous main node work, and set the other nodes as slave nodes respectively, and the current main node broadcasts the heartbeat message containing the own logical address to the other nodes according to a preset time interval.
Specifically, as an embodiment, after the node setting module 2 sets the current master node, the node monitoring module 3 is further configured to monitor a restart state of a previous node that stops broadcasting, and in response to a restart of the previous node that stops broadcasting, determine whether a logical address of the previous node that is restarted is smaller than a logical address of the current master node, if so, invoke the node setting module to reset the current master node on the previous node that is restarted, and set the remaining nodes as slave nodes, respectively, and the current master node broadcasts a heartbeat packet including its own logical address to the remaining nodes according to a preset time interval.
Preferably, as an embodiment, the node setting module 2 is further configured to select a node with the smallest logical address from all the restarted previous nodes and reset the node as the current master node when the number of the restarted previous nodes is at least two and the logical addresses of all the restarted previous nodes are smaller than the logical address of the current master node.
