Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The blockchain system refers to a system for data sharing between nodes, and the blockchain system may include a plurality of nodes, and the plurality of nodes may refer to respective clients in the blockchain system. Each node may receive input information during normal operation and maintain shared data within the blockchain system based on the received input information. In order to ensure the information intercommunication in the blockchain system, information connection can exist between each node in the blockchain system, and the nodes can transmit information through the information connection. For example, when an arbitrary node in the blockchain system receives input information, other nodes in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain system are consistent.

Therefore, the contents in the blocks in the blockchain are related, and the same blockchain is stored in each node of the blockchain system, so that once the blocks in the blockchain are created, the contents in the blocks cannot be modified, and the security of the data in the blocks in the blockchain can be ensured.

However, in the related art, the utilization of the blockchain is still only a simple way to directly utilize the blockchain for data reading and writing. When a user needs to realize certain functions by using the block chain, the user needs to design a scheme by himself to control the block chain to realize the corresponding functions, so that a plurality of different users can repeatedly carry out scheme design, and social human resources are wasted. Moreover, from the perspective of the user, when the user needs to implement some functions by using the block chain technology, the operation is also very cumbersome.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture of a cluster system 1000 according to an embodiment of the present application, where the cluster system 1000 includes a cluster management device 100 and one or more clusters 200.

Each cluster 200 includes a node control device 201 and a plurality of link points 202, where the number of the plurality of fingers may be 0, or may be 1, 2, 3, or a number corresponding to another natural number. Each link node can receive input information when working normally, and maintain shared data in the cluster based on the received input information. In order to ensure information intercommunication in the same cluster, information connection can exist between each chain node in the same cluster, and information transmission can be carried out between the chain nodes through information connection. For example, when any link node in a cluster receives input information, other link nodes in the cluster acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all link nodes in a cluster are consistent.

Each link node in one cluster has a node identifier corresponding thereto, and each link node in one cluster may store node identifiers of other link nodes in the cluster, so that the generated tile is broadcast to other link nodes in the tile link system according to the node identifiers of the other link nodes in the following. Each link node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol ) address and any other information that can be used to identify the link node, and table 1 only illustrates the IP address as an example.

Referring to fig. 2, in the embodiment of the present application, a container is created on each link node, and an identical block chain is deployed in the container of each link node in the same cluster. The node control device comprises a proxy module and one or more services. The agent module is used for receiving the instruction issued by the cluster management device and controlling the block chains in each chain node to read and write data on the corresponding chain node by using one or more services according to the instruction issued by the cluster management device.

Referring to fig. 3, a block chain is composed of a plurality of blocks, a starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

Referring to fig. 4, fig. 4 is a schematic diagram of a hardware structure of a cluster management device 100 according to an embodiment of the present application. Cluster management device 100 includes a processor 101, a memory 102, a communication interface 103, and one or more programs stored in memory 102 and configured to be executed by processor 101, the programs including instructions to perform the steps of the node management method of any of the following embodiments. Memory 102 includes Random Access Memory (RAM), and disk storage. The communication interface 103 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface).

The cluster management device can call one or more services of any one cluster in the cluster system to realize the function corresponding to each service. For example, if a shared account book service is deployed in a node control device of a cluster of the cluster system, the cluster management device issues an instruction to an agent module of the node control device to instruct to start a shared account book service process corresponding to the shared account book service on the node control device to provide the shared account book service. The shared account book service process can utilize the block chain in the cluster to read and write data, and the function of sharing the account book is realized. The node control device of a cluster can deploy a plurality of services, and the plurality of services can utilize the blockchain read-write data in the cluster to realize the business function corresponding to each service.

In the cluster system, each cluster is managed by adopting the container, so that the block chains can be deployed on each link point by adopting a standardized strategy specification, and the transportability is good. The individual services on the node control device may be provided by a dedicated service provider. The user can use the cluster management device to call the service of each cluster, and the user can use the service of each cluster to control the corresponding block chain to read and write data, so as to realize the corresponding function of each service. For users, the operation mechanism of the cluster does not need to be concerned, and the learning cost of using the block chain for the users is lower.

In the prior art, a method for adding a node in a block chain network is that a user firstly purchases a node, then deploys a block chain on the node, and then adds the node into the block chain network; and purchasing a next node, deploying a block chain on the next node, adding the next node into the block chain network, and so on to realize the addition of a plurality of nodes into the block chain network, wherein the process of adding the nodes in the block chain network is serial.

By adopting the cluster system based on the block chain technology provided by the embodiment of the application, when a user needs to add a new chain link point to a cluster. If a user needs to purchase a link node first, then create a container at the link node, then add the link node into the cluster, and then start a block chain process in the container of each link node of the cluster by using the node control device through the cluster management device according to the method for serially adding the nodes in the prior art. Therefore, a user needs to create a new cluster, and when the cluster starts a block chain, the user needs to create a cluster first, and then sequentially add each link point into the cluster by sequentially executing the steps of adding new link points into the cluster, so that the operation is very complicated, and the operation of adding each node into the cluster can only be serial. Therefore, when a user needs to create a new cluster and starts a block chain, or when the user needs to add a new link point into an existing cluster, the operation is very complicated for the user, and the operation can only be serial.

Referring to fig. 5, fig. 5 is a flowchart illustrating a node management method according to an embodiment of the present application. The node management method of the embodiment of the application includes, but is not limited to, the following steps:

501. the method comprises the steps that cluster management equipment obtains a new node request of a first node cluster triggered by a user, wherein the new node request comprises a target node identifier of a target link node and a first cluster identifier of the first node cluster;

the user can trigger a new node request of the first node cluster in the front-end page by accessing the front-end page provided by the cluster management device at the terminal.

Specifically, when the user does not have a cluster, the cluster creation instruction may be triggered first, and when the cluster management device obtains the cluster creation instruction, a node cluster is created for the user according to the cluster creation instruction. When the cluster creation is just completed, the node cluster comprises a node control device and a plurality of chain nodes. If the cluster creating instruction contains the node identification of the link node provided by the user, the cluster management equipment creates a node cluster and adds the corresponding link node into the node cluster according to the node identification in the cluster creating instruction; if the cluster creation instruction does not include the node identifier of the link node provided by the user, that is, the user does not provide the link node when triggering the cluster creation instruction, the cluster created by the cluster management device only includes one node control device. The user may subsequently trigger a node adding request to request the cluster management device to add a new link node in the node cluster.

502. The cluster management equipment acquires node state information of the target link node from the node state library according to the target node identifier;

the node state library stores node state information of a plurality of nodes. Specifically, each node state information may correspond to a user identification. Then, the cluster management device may find the target node identifier from one or more nodes corresponding to the user identifier of the user, and obtain the target node state information corresponding to the target node.

503. The cluster management equipment judges whether the target link node meets the condition of joining the cluster according to the node state information of the target link node;

the joining cluster condition may be that the user has obtained the usage right of the target link node, for example, the user may obtain the usage right of the target link node by purchasing. The cluster management device may obtain the state of the target node according to the state information of the target node, for example, when the user purchases the target node, the cluster management device records that the target link node is in the purchased state in the state information of the target node in the node state library, and then may confirm that the target link node meets the condition of joining the cluster. When the user does not purchase the target node, the cluster management device records that the link node is in a to-be-purchased state in the target node state information of the node state library, and then the target link node does not meet the condition of joining the cluster. Of course, in other embodiments, the join cluster condition may also be other conditions, and is not limited herein.

504. And when the target node state meets the condition of joining the cluster, the cluster management equipment sends a container creating instruction to the node control equipment.

When the target link node is in the purchased state, then the cluster management device may instruct the node control device to create a container at the target link node device. The container creation instruction includes a target node identifier of the target link node.

505. The node control equipment controls the target link points to create a target container;

the node control device communicates with the cluster management device through the agent module. And the agent module receives a container creation instruction sent by the cluster management equipment. The node control equipment stores a container creation script, when the node control equipment receives a container creation instruction, a proxy module of the node control equipment calls and executes the container creation script, and the node control equipment controls a link point creation container corresponding to a node identifier in the container creation instruction. When the container creating script is executed, the control chain node creates a container according to the block chain image file, and thus the block chain is deployed in the created container. It is understood that in the same cluster, containers on various nodes are created from the same blockchain image file. When the container creation instruction contains the target node identifier, the node control equipment controls the target link node to create the target container, and the block chain is deployed in the created target container.

506. The node control equipment sends a container creation success message to the cluster management equipment;

specifically, the container creation success message includes a node identifier of the first link node, and after the node control device detects that the target container is created by the target link node, the proxy module of the node control device sends the container creation success message to the cluster management device.

After receiving the container creation success message, the cluster management device may record the state of the target link node as the created container state in the node state library. After receiving the container creation success message corresponding to each link point, the cluster management device changes the state of the link node into the created container state in the node state library.

507. The cluster management equipment adds the target link point into the first node cluster;

after receiving the container creation success message sent by the agent module of the node control device, the cluster management device may confirm that the target link node has created the container, and may add the target link node to the first node cluster.

508. The cluster management equipment acquires first node state information of each first chain node of the first node cluster from the node state library, and judges whether a first chain node of a running block chain process exists on each first chain node of the first node cluster according to the first node state information;

it should be noted that, after the target link node is added to the first node cluster, the target link node is a link node in the first node cluster, that is, the target link node is also a first link node. The cluster management device acquires state information of the first target link node and node state information of original link nodes in the first node cluster.

When the first node state information records that the first link point is in the starting state, the first link point can be determined to be running the block chain process. Then, the cluster management device may traverse the first node state information of each first link node, and determine whether each first link node is running a blockchain process according to the first node state information of each first link node.

509. When the first chain node of the running block chain process does not exist, the cluster management equipment acquires the first node number of the first chain node and judges whether the first node number is greater than or equal to the node number threshold value or not;

when the first link node of the running block link process does not exist, the cluster management equipment acquires the first node number of the first link node, and when the first node number is larger than or equal to the node number threshold value, the cluster management equipment judges whether each first link node is in a created container state or not according to the first node state information; when each first link node is in the created container state, it can be confirmed that the first node cluster conforms to the block chain start condition. The threshold number of nodes may be, for example, 4. Of course, in other embodiments, the node number threshold may also be other values greater than 4, for example, 5, 6, 7, etc., and the node number threshold is not limited herein.

510. When the number of the first nodes is larger than or equal to the threshold value of the number of the nodes, the cluster management equipment judges whether each first chain node is in a created container state or not according to the state information of the first nodes;

only each first link node has created a container, that is, only each first link node is in the created container state, and the first node cluster meets the block chain starting condition.

511. When each first link node is in the created container state, the cluster management device sends a link start instruction to the node control device.

When each first link node is in the created container state, the cluster management device may determine that the first node cluster conforms to the block chain start condition. In this way, the cluster management device sends a chain starting instruction to the node control device, where the chain starting instruction is used to instruct the node control device to control each first link node to start the first blockchain process.

If there is a first link node without creating a container, the cluster management device needs to wait until the first link node creates a container, and then send a link start instruction to the node control device.

512. The node control device controls each first chain node to start a first blockchain process in a container of the first chain node according to the chain start instruction.

Specifically, after receiving the chain start instruction, the agent module of the node control device issues a configuration file for each first link point, and controls each first link point to start a first blockchain process in the container according to the configuration file. The configuration file may comprise, for example, a first node identification of each first chain node.

513. When there is a first link node that is running a block link process, the cluster management device sends a link restart instruction to the node control device.

When there is a first link node that is running a blockchain process, it may be determined that the number of the first node of the first blockchain is greater than the threshold number of nodes, and since the newly added target link node is in a created container state, it may be determined that the first node cluster meets a blockchain starting condition.

514. And the node control equipment controls the first chain link point of the running block chain process to end the running block chain process according to the chain restart instruction, and controls each first node to start the first block chain process.

Due to the addition of the link points, the configuration of each original link point can be changed. For example, a new node may be added to the node identification list. Then, each first link node of the currently running blockchain process needs to end the currently running blockchain process, and then starts the first blockchain process in the container according to the configuration file uniformly issued by the node control device.

By adopting the node management method of the embodiment of the application, the cluster management equipment firstly acquires a new node request of a first node cluster triggered by a user, wherein the new node request comprises a target node identifier of a target link node; then, acquiring target node state information of a target link node from a node state library according to the target node identifier, wherein the node state information of each link node in the block link system is stored in the node state library; when confirming that the target link point is in accordance with the condition of adding the target link point into the cluster, the cluster management equipment controls the target link point to create a target container by using the node control equipment, and adds the target link node into the first node cluster, wherein the target container is created according to the block chain image file; and then when the first node cluster is determined to meet the block chain starting condition according to the first node state information of each first chain node in the first node cluster, controlling each first chain node to start a first block chain process in a container of the first chain node by using the node control equipment. Therefore, when a user needs to add a new link node into the first node cluster, only the request for adding a new node needs to be triggered, and the subsequent steps can be executed in sequence by the cluster management device according to the node state information of the target link node in the node state library, so that the target link node and each first link node in the first node cluster are controlled to start the first block link process in the target container. Moreover, due to the node state library, when a plurality of chain nodes need to be added into the cluster, the cluster management equipment can manage each chain node needing to be added into the cluster in parallel according to the node state information of each chain node in the node state library, and add each chain node needing to be added into the cluster, so that the plurality of chain nodes can be added into the cluster more efficiently.

In addition, in the cluster system, each cluster is managed by adopting a container, so that a block chain can be deployed on each link point by adopting a standardized strategy specification, and the portability is good. The individual services on the node control device may be provided by a dedicated service provider. The user can use the cluster management device to call the service of each cluster, and the user can use the service of each cluster to control the corresponding block chain to read and write data, so as to realize the corresponding function of each service. For users, the operation mechanism of the cluster does not need to be concerned, and the learning cost of using the block chain for the users is lower.

For example, when a link node meeting the condition of joining a cluster is acquired according to the node state information of each link node in the node state library, the cluster management device may create a container at the link node and join the link node into the node cluster. That is, when the cluster management device creates a container on one link node, it may also create a container on another link node synchronously, or add another link node into the node cluster, and as long as it is determined that the link node can enter the next state according to the node state information of the node state library, the cluster management device may control the link node to enter the next state.

In an embodiment of the present application, the node control device may be provided by a provider of the blockchain service. The cluster management equipment can deploy one or more services on the node control equipment according to the user requirements, and when each service is started, the cluster management equipment controls the block chains on the link points to read and write data so as to realize the business function corresponding to each service. In this way, the cluster management device may invoke one or more services of any one cluster in the cluster system to implement the business function corresponding to each service.

Further, in this embodiment of the present application, the cluster management device may include a plurality of node control modules, where different node control modules are configured to control a link node to enter different states according to node state information of each link node in the node state library, and record a state of the node in the node state library after a state of the link node is changed. For example, a container may be created by a first node control module control node, a second node control module control node joins a cluster, and a third node control module controls each node to start a blockchain process. Then step 502 and 504 may be implemented by the first node control module, which may further record the node status of the first target node as the created container status in the node status library upon receiving the container creation success message. Step 507 may be implemented by a second node control module, where the second node control module is specifically configured to add, to the first node cluster, the first link node whose node state is the created state according to the state information of each point in the node state library, and change the state of the first link node in the node state library to the state of having been added to the first node cluster. Step 508 and step 512, step 511 and step 513 can be implemented by a third node control module, where the third node control module is configured to control each first link node to start the first block link process in the container when it is determined that the first node cluster meets the block link starting condition according to the first node state information of each first link node in the node state library, and record the state of each first link node as a started link state in the node state library after receiving a starting success instruction sent by the node control device. Thus, each module is responsible for controlling the link nodes to enter the next state, when a plurality of link nodes need to be added into the cluster and the block chain is started, container creation and cluster adding operations can be performed on the plurality of nodes in parallel, for example, when the first node control module adds the link node 1 into the cluster, the second node control module controls the link node 2 to create a container, and the container creation by the link node 2 does not need to be controlled after the link node 1 is added into the cluster.

It should be noted that the plurality of control modules are modules for facilitating understanding of the division, and are only used to illustrate that the cluster management device controls the link point to enter the next state according to the node state information of each link node in the node state library, and records the state of the link node in the node state library after the state of the link point is changed.

Based on the foregoing embodiments, in some embodiments, the node management method further includes: and the cluster management equipment judges whether an expired link node exists in the first node cluster according to the first node state information, and if the expired link node exists, the cluster management equipment controls the first block link process in the expired link node to stop running by utilizing the node control equipment. Generally, a user purchases a link node with valid duration, the link node with the valid duration is an expired link node, and the user loses the use authority of the link node. In this way, the first blockchain process in the expired chain node stops running, the expired chain node is in an unavailable state, and the data of the first chain node cannot be synchronized with other first chain nodes.

That is, the cluster management device also monitors whether an expired link node exists in each first node in the cluster management device, and controls the first blockchain process in the expired link node to stop running. The process may be implemented by a fourth node control module. Specifically, the fourth node control module judges whether an expired link node exists in the first node cluster according to the first node state information, and if the expired link node exists, the fourth node control module controls the first block link process in the expired link node to stop running by using the node control equipment.

Further, the cluster management device judges whether an overdue link node, the expiration time of which exceeds the expiration threshold time, exists in the first node cluster or not according to the first node state information, and if the overdue link node exists, the cluster management device removes the overdue link node from the first node cluster. It can be understood that although the first blockchain process is stopped, the outdated chain node is still in the cluster, and if the user obtains the usage right of the outdated chain node within the expiration time, the cluster management device can restart the first blockchain process in the outdated chain node. If the user does not obtain the use permission of the expired block chain within the expired duration, the expired chain node is converted into an expired chain node, and the cluster management equipment removes the expired chain node from the first node cluster. The process can be implemented by the fifth node control module, that is, the fifth node control module determines whether there is an over-period link node whose expiration time length has exceeded an expiration threshold time length in the first node cluster according to the first node state information, and if there is an over-period link node, the fifth node control module removes the over-period link node from the first node cluster.

In some embodiments, the node management method further comprises: the cluster management equipment can receive a service starting request triggered by a user, wherein the service request is used for requesting the cluster management equipment to start a target service; the cluster management equipment acquires a target cluster identifier of a target node cluster where a target service is located; the cluster management device sends a service starting instruction to target node control equipment of the target node cluster according to the target cluster identifier, the service starting instruction is used for indicating the target node control equipment to start a target service process corresponding to the target service, and the target service process is used for realizing a business function corresponding to the target service by controlling each block chain process read-write data in the target node cluster.

Therefore, the cluster management equipment can call the service corresponding to the service starting request according to the service starting request triggered by the user and realize the service function corresponding to the service.
