Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a node initialization method according to an embodiment of the present invention, where the present embodiment is applicable to a node initialization situation, and the method may be executed by a node initialization apparatus, where the apparatus may be implemented in a software and/or hardware manner, and may be integrated in a notebook, a tablet, and the like, and referring to fig. 1, the method may include the following steps:
s110, when the backup node is initialized, the backup node sends a data synchronization request to the slave node.
Wherein the data synchronization request comprises a first node identification of the backup node and a second node identification of the slave node. The first node identification is an identification that uniquely identifies the backup node. The second node identification is an identification that uniquely identifies the slave node. The first node identification and the second node identification are different. For example, the first node identification and the second node identification may be different node numbers.
The Redis structure is a tree structure or a chain topology including a plurality of nodes for managing data. The traditional Redis structure only comprises a master node and a slave node, wherein the master node and the slave node can be understood as a memory database, the data in the master node and the data in the slave node are the same, but only the master node can provide service for the outside, and the slave node is used for storing the data. The same Redis structure usually includes only one master node, and the number of slave nodes may be set according to actual needs, that is, one or more slave nodes may be provided. In the embodiment, a master node and a slave node are taken as an example, when the master node fails or is restarted for some reason, the slave node is upgraded to a new master node, when the original master node is recovered, the original master node becomes a new slave node, and when the new slave node is initialized, data of the new master node needs to be copied, so that the new master node cannot continue to provide service to the outside, and particularly when the data volume is large, the use of the new master node is seriously influenced.
Therefore, in this embodiment, backup nodes are preset in the Redis structure, the number of the backup nodes may be set according to actual needs, and when the number of the backup nodes is large, the execution efficiency of the system is easily reduced. Exemplarily, referring to fig. 2, fig. 2 is a schematic diagram of a Redis structure according to an embodiment of the present invention. The number 1 node is a master node, the number 2 node is a slave node, the number 3 node is a backup node, and data in the backup node is consistent with the master node and the slave node. It can be understood that, in practical applications, the number of the slave nodes and the backup nodes included in the Redis structure is more than one, and in order to ensure normal data replication, when the backup node is initialized, a data synchronization request is first sent to the corresponding slave node, and after the corresponding slave node passes verification, the backup node replicates data of the corresponding slave node, without affecting the master node to continue providing services to the outside. It should be noted that three nodes in the Redis structure may be changed according to actual situations, for example, when node 1 fails, node 2 may be changed from a slave node to a master node, and correspondingly, node 3 is changed from a backup node to a slave node.
S120, the slave node determines the validity of the data synchronization request according to the first node identifier and the second node identifier, and when the data synchronization request is legal, the slave node copies data to the backup node.
The slave node and the backup node have corresponding association relationship, and the association relationship can be preset and stored. When the data synchronization request is applied, whether the data synchronization request is legal or not can be determined by searching the pre-stored association relation. For example, it is first determined whether the second node identifier in the synchronization request is consistent with the node identifier of the slave node itself, if so, it is further determined whether a corresponding relationship exists between the second node identifier and the first node identifier, if so, the data synchronization request is considered to be legal, the slave node may copy the data to the backup node, otherwise, the data synchronization request is considered to be illegal, and the slave node returns a response result indicating that the verification fails to the backup node. Through the verification, the normal operation of the data copying process is ensured, and repeated copying is avoided.
The embodiment of the invention provides a node initialization method, when a backup node is initialized, the backup node sends a data synchronization request to a slave node, the data synchronization request comprises a first node identifier of the backup node and a second node identifier of the slave node, the slave node determines the validity of the data synchronization request according to the first node identifier and the second node identifier, and when the data synchronization request is legal, the slave node copies data to the backup node. Compared with the prior art, the embodiment of the invention adds the backup node in the Redis structure, when the backup node is initialized, the data of the slave node is copied, so that the initialization of the backup node is finished, other nodes such as a master node are not influenced to provide services outwards, and the availability of the system is improved.
On the basis of the above embodiment, the validity of the data synchronization request can be determined as follows:
the slave node acquires a node association information table, and the node association information table is used for storing the association relationship between the backup node and the slave node;
if the incidence relation between the first node identification and the second node identification exists in the node incidence information table, the slave node determines that the data synchronization request is legal; otherwise, determining that the data synchronization request is illegal.
The node association information table may be preset, and may be updated according to actual needs, for example, to change, add, or delete association relationships between different nodes. Optionally, the node association information table may store information such as a node name, a node identifier, and a function description. And matching the acquired first node identification and the acquired second node identification with the node association information table by the slave node, if the matching is successful, namely the association relationship between the first node identification and the second node identification exists in the node association information table, considering that the data synchronization request is legal, and otherwise, considering that the data synchronization request is illegal. By verifying the validity of the data synchronization request, the normal operation of the data copying process is ensured, and the repeated copying is avoided.
Example two
Fig. 3 is a flowchart of a node initialization method according to a second embodiment of the present invention, which is optimized based on the second embodiment, and referring to fig. 3, the method includes the following steps:
and S210, taking the slave node as a master node of the backup node.
Nodes in the Redis structure generally have a master-slave relationship, for example, the Redis structure includes node A and node B, if node B copies data of node A, node A and node B are considered to have the master-slave relationship, and node A is a master node of node B. The embodiment sets the slave node as the master node of the backup node, namely the backup node copies the data of the slave node during initialization, thereby not influencing the use of the master node.
S220, when the backup node is initialized, the backup node sends a data synchronization request to the slave node.
S230, the slave node determines the validity of the data synchronization request according to the first node identifier and the second node identifier, and when the data synchronization request is legal, the slave node copies data to the backup node.
And S240, when the master node fails, the slave node serves as a new master node, and the backup node serves as a new slave node.
When the master node fails, in order to not affect external services, the properties of the remaining nodes need to be changed, that is, the slave nodes need to be upgraded to new master nodes, and the backup nodes need to be upgraded to new slave nodes. As shown in fig. 2, when node 1 fails, node 2 is upgraded to a master node, node 3 is upgraded to a slave node, and then node 2 replaces node 1 to continue providing services to the outside. The embodiment does not limit the reason for the failure of the master node.
And S250, when the main node is recovered, the main node is used as a new backup node, and the new slave node is the main node of the new backup node.
As shown in fig. 2, when the node 1 is restored, the node 1 is a new backup node, and the node 3 is a master node of the node 1, so that the node 1, the node 2, and the node 3 form a chain topology structure. When the node 1 is initialized, the data of the node 3 can be directly copied, so that the normal operation of the node 2 is ensured, and the availability of the system is improved.
And S260, when the new backup node is initialized, the new slave node copies the data to the new backup node.
The second embodiment of the present invention provides a node initialization method, based on the above embodiments, a backup node is added, a slave node is set as a master node of the backup node, data of the slave node is copied when the backup node is initialized, and when the master node fails, the slave node is upgraded to be a new master node, the backup node is a new slave node, the new master node replaces an old master node to continue providing services to the outside, and when the old master node is restored, the new master node is used as a new backup node, and data of the new slave node is copied, so that the use of the new master node is not affected, that is, the data of the slave node copied by the backup node is always maintained in the whole process, and the availability of the system is improved.
On the basis of the foregoing embodiment, optionally, when there is a blank node added, setting the current slave node as the master node of the blank node, so that the current slave node copies data to the blank node, and ensures normal operation of the current master node.
