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.
Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture of a service installation system 1000 according to an embodiment of the present application, where the service installation system includes a blockchain system 100 and a service management apparatus 200.
The blockchain system 100 refers to a system for data sharing between nodes, and the blockchain system may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the blockchain system. Each node 101 may receive input information and maintain shared data within the blockchain system based on the received input information while operating normally. 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.
Each node in the blockchain system has a corresponding node identifier, and each node in the blockchain system can store node identifiers of other nodes in the blockchain system, so that the generated block can be broadcast to other nodes in the blockchain system according to the node identifiers of other nodes. Each 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 node, and table 1 only illustrates the IP address as an example.
Each node in the blockchain system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 2, the block chain is composed of a plurality of blocks, the 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.
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.
In the related art, if a user needs to read and write data by using a block chain to realize a corresponding function in some scenes, the user needs to design a realization logic, generate an executable file, and execute the executable file by using a node to realize the corresponding function. Since the user needs to design the implementation logic by himself or herself, and not everyone has the ability to design the implementation logic by himself or herself, the use threshold of the block chain service is too high, and an ordinary user can only use the block chain to perform simple data reading and writing, so that the utilization degree of the block chain technology is shallow, and the advantages of the block chain technology are not fully exerted. Moreover, even for a person who has the ability to design and implement logic by himself, the process of implementing corresponding functions by using the block chain is cumbersome.
As shown in fig. 3, each node in the blockchain system of the embodiment of the present application includes an agent module and one or more blockchains. The agent module is used for communicating with the service management device. Specifically, the agent module may be configured to receive a control instruction of the service management device, and execute an operation corresponding to the control instruction. The user can deploy one or more service installation files of the service on the nodes of the blockchain network, and when the service is needed to be used, the service management device sends an instruction to the agent module, so that the agent module starts a service process corresponding to the service according to the service installation files to realize the function corresponding to each service. Specifically, when the service process is started, the service process may perform data read-write operation by using the blockchain, thereby implementing a service function corresponding to each service.
For example, a shared ledger service may be deployed on one node device in the blockchain system, and a shared ledger service process corresponding to the shared ledger service is started to provide the shared ledger service. The shared account book service process can utilize the block chain to read and write data, and the function of sharing the account book is realized. One node device in the blockchain system can deploy a plurality of services, and one node device can run service processes corresponding to the plurality of services, for example, a node in the blockchain system can run a digital asset service process corresponding to the digital asset service and a supply chain financial service process corresponding to the supply chain financial service. The node may then implement digital asset service functions and supply chain financial service functions to provide digital asset services and supply chain financial services to the user.
In this way, a user may deploy one or more services on nodes of the blockchain network, and when the user needs to process data using blockchains to implement some functions, the corresponding functions may be implemented by invoking service processes in the node devices. Therefore, more functions can be realized by using the block chain, and the block chain technology is more fully utilized.
Referring to fig. 4, fig. 4 is a schematic hardware structure diagram of a service management device 200 according to an embodiment of the present disclosure. The service management device 200 comprises a processor 201, a memory 202, a communication interface 203, and one or more programs stored in the memory 202 and configured to be executed by the processor 201, the programs including instructions to perform the steps of the service installation method of any of the following embodiments. Memory 202 includes Random Access Memory (RAM), and disk storage. The communication interface 203 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface).
Referring to fig. 5, fig. 5 is a schematic flow chart of a service installation method according to an embodiment of the present application, where the service installation method according to the embodiment of the present application includes the following steps:
501. the service management equipment acquires a version selection instruction triggered by a user, wherein the version selection instruction comprises a first service version identifier corresponding to a first target service selected by the user.
When a user needs to deploy a first target service on a node of the blockchain network, or when the blockchain network already deploys the first target service but needs to reselect a service version of the service process, a version selection instruction can be triggered by a first target page provided by the service management device. The target page may be a web front end page provided by the service management device. And selecting the service version corresponding to the first target service, triggering a version selection instruction, and obtaining a first service version identifier corresponding to the service version selected by the user by the service management equipment.
As shown in fig. 6, the terminal accesses the first target page 600, the first target page 600 includes a plurality of pull-down controls 601 and 604, the user can make the first target page 600 display a plurality of versions corresponding to the service a through the pull-down controls, and select one version from the plurality of versions, for example, if the user clicks the pull-down control 601, the plurality of versions of the service a can be displayed, and if the user selects the version 101, the service management device obtains the version identifier selected by the user through the first target page 600 as the first service version identifier.
502. The service management device acquires a first service installation file corresponding to the first service version identification.
The service management device may obtain a first service installation file corresponding to the first service version identifier from the installation file database. Specifically, the installation file database stores service installation files of a plurality of services, and each service corresponds to one or more service installation files. Each service installation file corresponds to a service version identification. The service version identification may install a corresponding version number for each service. In this way, the service device may find the first service installation file corresponding to the first service version identifier according to the first service version identifier. The installation file database may be a database stored in a memory of the service management device, or may be a database stored in another device and accessible by the service management device.
503. The service management device sends a service installation instruction to a first target node corresponding to the first target service, wherein the service installation instruction comprises a first service installation file.
For example, service a includes service version 101, service version 102, and service version 103, which are 3 service versions, each corresponding to a different service installation file. The user may select one version from service version 101, service version 102, and service version 103. If the user selects the service version 101, the version selection instruction includes the service version identifier of the service version 101, and the service management device acquires the service installation file corresponding to the service version 101 according to the service version identifier of the service version 101 and sends the service installation file to the corresponding target node through the service installation instruction.
The service installation instruction is used for indicating a first target node to run a first service installation file when receiving a first starting instruction of a first target service, so as to start a first service process corresponding to the first target service on the first target node, wherein the first service process is used for realizing a service function corresponding to the first target service by using a block chain on the first target node.
The first service installation file of the service management equipment part is sent to the first target node, and then the first target node can run a first service process corresponding to the first target service according to the first service installation file, so that a service function corresponding to the first service is realized.
The first target node may be a node where the first service has been deployed, or may be a node selected by a user. Specifically, when the service management device detects that an installed service corresponding to a first target service exists in the blockchain network, the service management device sends a service installation instruction to a first target node where the installed service is located; when the installed service corresponding to the first target service does not exist in the blockchain network, the service management device sends a service installation instruction to the first target node selected by the user.
In this way, after the service management device obtains the version selection instruction, whether the installed service corresponding to the first target service exists in the block chain network is detected, and if the installed service exists, the node where the installed process is located is used as the first target node; and if not, taking the node selected by the user as a first target node.
The node selected by the user may be selected by the user when the version selection instruction is triggered, and the version selection instruction includes the node identifier of the first target node. For example, in the example shown in fig. 6, the user selects the version of service a on node 1, and the user-triggered version selection instruction includes the node identification of node 1. The service management device may send a service installation instruction to the first target node according to the node identifier of the first target node. Thus, the service management device can complete service deployment more efficiently.
The node selected by the user may also be that, when the service management device confirms that an installed service process corresponding to the target service does not exist in the blockchain network, that is, when the target service is installed in the blockchain network for the first time, the service management device sends a node selection prompt to enable the user to select a first target node for deploying the first target service, the server obtains a node identifier of the first target node selected by the user according to the selection operation of the user, and then sends a service installation instruction to the first target node according to the node identifier of the first target node.
The service management device stores service identifiers of one or more installed services in the block chain network and node identifiers of nodes where each installed service is located. The version selection instruction also includes a service identification of the first target service. The service management device may detect whether a service identifier of the first service exists in the stored service identifiers of the one or more installed services. If so, the existence of the installed service corresponding to the first target service in the blockchain network can be confirmed. And if not, confirming that the installed service corresponding to the first target service does not exist in the blockchain network.
Further, when the service management device detects that the installed service corresponding to the first target service exists in the blockchain network, the service management device obtains an installed service version identifier of the installed service; when the installed service version identification of the installed service is different from the first service version identification, the service management device sends a service installation instruction to a first target node where the installed service process is located. In this way, if the installed service version identifier of the installed service is the same as the first service version identifier, it is described that the first service installation file corresponding to the first service version identifier exists in the first target node of the block chain network, and it is not necessary to send the same service installation file to the first target node again, so that resources of the first target node can be saved, and the processing load of the service management device can be reduced.
504. And the first target node installs the first service on the first target node according to the first service installation file.
Specifically, when an installed service corresponding to the first target service exists on the first target node, the first target node installs the first service on the first target node according to the first service installation file, and deletes the installed service. When there is an installed service corresponding to the first target service on the first target node, the following two cases are divided. If the first target node receives the service installation instruction, the first target service is in a starting state, the first target node runs a first service process corresponding to the first target service, the first target node ends the running first service process, deletes the installed service, installs the first service on the first target node according to the first service installation file, and starts a new first service process. And if the first target node receives the service installation instruction, the first service is in a closed state, and the first service corresponding to the first target service is not operated, the first target node installs the first service on the first target node according to the first service installation file, and deletes the installed service. That is, if there is an installed service corresponding to the first target service on the first target node, the first target node installs the first service according to the first service installation file when receiving the service installation instruction, and keeps the starting state of the first service consistent with the state of the first service when the first node receives the service installation instruction.
If the first target service is not installed on the first target node, or the first target node has the installed first target service and the first service is in a closed state, the service management device sends a first starting instruction to the first target node when subsequently receiving a first starting request corresponding to the first service triggered by the user. The first starting instruction comprises a service identifier of the first service. The first starting instruction is used for indicating the first target node to run a first service process corresponding to the first service according to the first installation file. Then, after receiving the first start instruction, the first node device starts a first service process corresponding to the first service according to the first service installation file. In this way, the first target node may initiate the corresponding service process according to the service version selected by the user. In this way, the first target node can utilize the first service process to control the block chain to read and write data, and realize the service function corresponding to the first service.
In this case, after the user selects the version and triggers the version selection instruction, the service management device does not control the first target node device to start the first service process of the first target service. Therefore, the problem that node resources are wasted due to the fact that the service process is started when the user only needs to deploy the service and does not need to start the service process immediately can be avoided.
It should be noted that the service management device may receive a start request of each service in the block chain, and control a node where each service is located to start a corresponding service process.
In an optional embodiment, a secure channel is established between the service management device and the first target node, and the service management device sends the service installation instruction to the first target node through the secure channel.
Specifically, key negotiation is performed in advance between the service management device and each node of the blockchain system, and a data encryption mode and a corresponding decryption mode are agreed. The service management equipment can encrypt the service installation instruction by using an appointed data encryption mode, the encrypted service control instruction is sent to a first target node in the block chain system, and the first target node decrypts the received service installation instruction by using an appointed decryption mode to obtain the decrypted service installation instruction.
In the service installation method of the embodiment of the application, the service management equipment firstly acquires a version selection instruction triggered by a user, wherein the version selection instruction comprises a first service version identifier corresponding to a first target service selected by the user; then acquiring a first service installation file corresponding to the first service version identification; and then sending a service installation instruction to a first target node corresponding to the first target service, wherein the service installation instruction comprises a first service installation file. In this way, a user can install one or more services on the nodes of the blockchain network by triggering the version selection instruction, and when the user needs to process data by using the blockchain to realize certain functions, the corresponding functions can be realized by calling one or more services in the node equipment. Therefore, more functions can be realized by using the block chain, and the block chain technology is more fully utilized. Moreover, since the functions of different service processes corresponding to one service process may be slightly different, when some functions need to be implemented by using the service installation file of the specified version, the user may also use the service management device control node to install the corresponding service according to the service installation file of the specified version by triggering the version selection instruction.
Based on the foregoing embodiment, in a further embodiment, when the service management device detects that the updated second service installation file exists in the second service in each installed service of the blockchain network, the service management device sends a service update instruction to the second target node where the second service is located, where the service update instruction includes the second service installation file.
In this way, the second target node may start a second service process corresponding to the second service according to the updated second service installation file. Specifically, if the service management device sends a service update instruction to a second target node where the second service is located, and a second service process corresponding to the second service is started in the second target node, the second target service ends the started second service process, and starts a new second service process according to the updated second service installation file. This allows service processes on various nodes in the blockchain network to be started according to the latest service installation file. And if the service management equipment sends a service updating instruction to a second target node where the second service is located, and the second target node does not start a second service process corresponding to the second service, starting the second service process according to the updated second service installation file when the second target node receives the second starting instruction of the second service.
Preferably, before the service management device sends the service update instruction to the second target node where the second service is located, the service management device may send an update prompt to the user, and after receiving the update confirmation instruction triggered by the user, the service update instruction may be sent to the second target node where the second service is located. Because the version of the installed service in the blockchain network may be a version selected by the user, that is, the version of the installed service is specified by the user when the version of the installed service is specified, the user may need to start the service process by using the service installation file of the specified version to implement the corresponding function. For a user-specified version of an installed service, no updates may be needed. Then, before updating, user confirmation is obtained, so that the service that the user does not need to be updated can be prevented from being updated.
Referring to fig. 7, the node control method according to the embodiment of the present application further includes the following steps:
701. one or more third target nodes send load information of the one or more third target nodes to the service management device;
the third target node may be any one of the nodes in the blockchain system. The third target node may be the same as the first target node or the second target node, or may be different. And the agent module of the third target node monitors the load information of the third target node and sends the load information to the service management equipment.
Specifically, the agent module of each node in the blockchain network may send load information of the third target node to each service management device at preset time intervals. The node may also send load information of a third target node to the service management device after receiving the load information acquisition request sent by the service management device. Thus, the service management device can acquire the load information of each node in the block chain network.
702. And the service management equipment judges whether the overload node exists in the one or more third target nodes according to the load information of the one or more third target nodes.
The load information may be, for example, the occupancy of the CPU, and/or GPU, and/or memory resources. The service management device may compare the load value in the load information with a preset load threshold, and when the load value exceeds the load threshold, determine that the third target node corresponding to the load information is an overloaded node. For example, if the load information includes the CPU occupancy, the CPU occupancy may be compared with a preset CPU occupancy threshold, and when the CPU occupancy exceeds the CPU occupancy threshold, it is determined that the third target node corresponding to the load information is an overloaded node.
703. The service management device acquires the historical running time of one or more overload service processes running on the overload node.
Specifically, the service management device may obtain a historical operating time of one or more overloaded service processes running on the overloaded node within a preset time period. The preset period may be, for example, within a month, within a week, within a day, or the like. This accurately reflects the latest enablement of each load service.
The node device can send a process running time length obtaining request to the agent module, the running time length obtaining request comprises process identifications of one or more service-carrying processes, and the agent module feeds back the running time lengths of one or more service-carrying processes to the service management device according to the process identifications.
704. And the service management equipment selects one or more service processes to be ended from one or more overload service processes according to the overload capacity and the historical running time of each overload service process.

For example, when the load information sent by the third target node includes that the CPU occupancy rate is 90% and the load threshold is 75%, the sequence from short to long according to the historical operation duration is obtained, the overload service processes running on the third target node are service processes 5, 6, 7, 8, and 9, the CPU occupancy rate of the service process 5 is 7%, the CPU occupancy rate of the service process 6 is 3%, the CPU occupancy rate of the service process 7 is 5%, the CPU occupancy rate of the service process 8 is 10%, and the CPU occupancy rate of the service process 9 is 15%. The historical operating time of the service process 5 is 6 hours, the historical operating time of the service process 6 is 2 hours, the historical operating time of the service process 7 is 3 hours, the historical operating time of the service process 8 is 5 hours, and the historical operating time of the service process 9 is 12 hours.
The service process 5, 6, 7 is ended, enabling the overload value of the service management device to be less than or equal to the load threshold; ending the service processes 5 and 8 also enables the overload value of the service management device to be less than or equal to the load threshold. Ending the service process 9 also enables the overload value of the service management device to be less than or equal to the load threshold.
If the preset number is 2, the 2 first optional process groups with the minimum total running time can be obtained as the first optional process group formed by the service processes 5, 6 and 7 and the first optional process group formed by the service processes 5 and 8.
And then, selecting a first optional process group formed by the service processes 5 and 8 from the two first optional process groups as a target optional process group, wherein the service processes 5 and 8 are service processes to be ended.
705. The service management device sends a process ending instruction to the overload node, wherein the process ending instruction comprises process identifications of one or more service processes to be ended, and the process ending instruction is used for indicating the overload node to end the one or more service processes to be ended.
After receiving the instruction of ending the process, the overload node ends one or more service processes to be ended according to the process identifiers of the one or more service processes to be ended, so that the load of the node is in a normal state.
Before sending a process ending instruction to an overload node, the service management device may send a process ending prompt, where the process ending prompt is used to prompt a user to end one or more service processes to be ended;
and after receiving the confirmation ending instruction triggered by the user, the service management equipment sends an ending process instruction to the overload node. Therefore, after the user confirms, the process to be ended is ended, the service which the user needs to use or is using can be avoided being ended, and the user experience is better.
Therefore, when the service management device detects the overload node, the service management device can control the overload node to end one or more service processes, so that the load of each node in the block chain network can be adjusted, and abnormal operation caused by overhigh load of the node production time is avoided.
