It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The block chain data cleaning method provided by the application can be applied to the application environment shown in fig. 1. Therein, the server 102 communicates with the node to be cleaned 106 included in the blockchain system 104 through a network. The server 102 stops each node in the blockchain system 104 and the associated service corresponding to each node; when each node and service in the block chain stop, acquiring a sequencing identifier, acquiring sequencing service from the associated service according to the sequencing identifier, deleting a data queue in the sequencing service, and generating a data cleaning instruction when the data queue is deleted; then logging in the node 106 to be cleaned according to the data cleaning instruction, deleting the data to be cleaned in the node 106 to be cleaned, restarting the associated service corresponding to the node 106 to be cleaned, and generating a channel replacement instruction when the associated service is restarted; according to the channel replacing instruction, a replacing channel is newly built, and the replacing channel is added to the node 106 to be cleaned; and finally, acquiring first configuration information of the replacement channel, inquiring the resource exchange server, modifying the channel configuration of the node to be cleaned according to the first configuration information, and starting the resource exchange server. The server 102 and the node 106 to be cleaned may be implemented by independent servers or a server cluster composed of a plurality of servers, and the block chain system 104 may be a distributed storage system including different nodes, may connect blocks generated by different nodes to form a block chain, and stores the formed block chain into different nodes.
In one embodiment, as shown in fig. 2, a method for clearing block chain data is provided, which is described by taking the method as an example applied to the server 102 in fig. 1, and includes the following steps:
Step 202, stopping each node in the block chain and the associated service corresponding to each node.
Specifically, each node and associated service in the blockchain may include: the system comprises a common identification node for sequencing data, a sequencing service associated with the common identification node, an endorsement node for verifying whether the data is legal, an endorsement service associated with the endorsement node, a data node for storing the data, a data storage service associated with the data node, a transaction node for initiating and stopping transactions, a transaction initiation service associated with the transaction node and the like, wherein the server stops the nodes and the associated services in a block chain and prepares for data cleaning in a subsequent block chain.
and 204, acquiring a sequencing identifier, acquiring a sequencing service from the associated service according to the sequencing identifier, deleting a data queue in the sequencing service, and generating a data cleaning instruction when the data queue is deleted.
Specifically, the ranking identifier is used to identify ranking services in the consensus node, such as kafka services connected by the consensus node, and the like. The data queue may be a data queue of test data to be cleaned, such as a topic (tag) in the kafka service, and the data cleaning instruction may be used to indicate the deletion of data to be cleaned in the node to be cleaned after the deletion of the data queue. The server obtains a sequencing identifier used for indicating a sequencing service, obtains the sequencing service connected with the consensus node according to the sequencing identifier, deletes a data queue in the sequencing service, and generates a data cleaning instruction.
and step 206, logging in the node to be cleaned according to the data cleaning instruction, deleting the data to be cleaned in the node to be cleaned, restarting the associated service corresponding to the node to be cleaned, and generating a channel replacement instruction when the associated service is restarted.
Specifically, the nodes to be cleaned may include a consensus node, an endorsement node, and a data node in the block chain, and the data to be cleaned may be residual data for testing, such as channel data in the consensus node, ledger data in the endorsement node and the data node, transient data, and the like. After the server acquires the data cleaning instruction, logging in the node to be cleaned according to the data cleaning instruction, deleting the data to be cleaned in the node to be cleaned, and restarting the associated service in the node to be cleaned after deleting the data to be cleaned in the node to be cleaned: the method can include the steps of identifying nodes and associated ordering services, endorsement nodes and associated endorsement services, data nodes and associated data storage services, and generating channel replacement instructions, wherein the channel replacement instructions are used for indicating the generation of replacement channels and the replacement of the replacement channels.
And step 208, creating a replacement channel according to the channel replacement instruction, and adding the replacement channel to the node to be cleaned.
Specifically, the replacement channel is used for replacing a block chain channel of an original data channel of the data to be cleaned, after the data to be cleaned is deleted, the original data channel where the data to be cleaned is located is correspondingly deleted, the specific building method of the block chain channel comprises the steps of entering a Docker cli container (a software package which is used for code processing, data operation and system setting in a block chain), then setting environment variables of the channel, adding channel related configuration data into the channel and the like, and after the block chain channel for replacement is newly built, adding the channel for replacement into the nodes to be cleaned, such as the common identification node, the endorsement node and the data node, which have been subjected to data cleaning.
Step 210, obtaining the first configuration information of the replacement channel and querying the resource exchange server, modifying the channel configuration of the node to be cleaned according to the first configuration information, and starting the resource exchange server.
Specifically, the first configuration information may be standard information of a replacement channel, such as information of a maximum transaction number, a maximum byte number, and the like, after the server acquires the first configuration information of the newly-built replacement channel, the server modifies the original channel configuration of the node to be cleaned according to the first configuration information, and queries the state of the resource exchange server, starts the resource exchange server if the resource exchange server is not started, and restarts the resource exchange server if the resource exchange server is in a started state.
In the block chain data cleaning method, the server stops each node in the block chain and the associated service corresponding to each node; when each node and service in the block chain stop, acquiring a sequencing identifier, acquiring sequencing service from the associated service according to the sequencing identifier, deleting a data queue in the sequencing service, and generating a data cleaning instruction when the data queue is deleted; then logging in a node to be cleaned according to the data cleaning instruction, deleting the data to be cleaned in the node to be cleaned, restarting the associated service corresponding to the node to be cleaned, and generating a channel replacement instruction when the associated service is restarted; according to the channel replacing instruction, a replacing channel is newly built, and the replacing channel is added to the node to be cleaned; and finally, acquiring first configuration information of the replacement channel, inquiring the resource exchange server, modifying the channel configuration of the node to be cleaned according to the first configuration information, and starting the resource exchange server. Compared with the prior art, the block chain data cleaning method capable of cleaning data in a block chain and improving the operation efficiency of the block chain is provided.
in an embodiment, as shown in fig. 3, in the block chain data cleaning method, before deleting the data to be cleaned in the node to be cleaned, the method may further include:
Step 302, when calibration data exists in the data to be cleaned in the node to be cleaned, backing up the calibration data in the node to be cleaned.
Specifically, the calibration data is the restoration data in the data to be cleaned, the data to be cleaned which can be restored by the restoration data can be restored by restoring the data to be cleaned again when subsequent error correction or inspection is needed, the data to be cleaned is detected and corrected, the server detects whether the data to be cleaned contains the calibration data before deleting the data to be cleaned in the node to be cleaned, and when the server detects that the calibration data exists in the data to be cleaned in the node to be cleaned, the detected calibration data is stored and reserved as backup data for subsequent data inspection.
and 304, when the data inspection request is received, restoring the data to be cleaned in the nodes to be cleaned according to the backed-up calibration data.
specifically, when the server receives the data checking request, the data to be cleaned in the node to be cleaned is restored according to the calibration data in the backed-up data to be cleaned, so that a user can conveniently check the data to be cleaned before deletion, and check whether the data to be cleaned is abnormal or not.
In the block chain data cleaning method, the block chain data cleaning method detects whether the data to be cleaned contains the calibration data before the data is cleaned, stores the calibration data when the data to be cleaned contains the calibration data, and restores the data when a data inspection request is subsequently received, so that a user can conveniently search for errors in the block chain data.
In an embodiment, after acquiring the first configuration information of the replacement channel and querying the resource exchange server, the method for clearing blockchain data may further include: acquiring second configuration information of a history channel in the history record, and matching the second configuration information with the first configuration information; and when the matching is successful, starting the resource exchange server.
Specifically, the second configuration information refers to configuration information of a historical data channel in a history record, after the server acquires first configuration information of a replacement channel and queries the current state of the resource exchange server, second configuration information of the historical data channel in the history record in the block chain is queried, the first configuration information of the replacement channel is matched with the second configuration information in the history record, when the second configuration information in the history record is matched with the first configuration information of the replacement channel, it is indicated that the configurations of the second configuration information and the replacement channel are the same, and if the second configuration information of the history record meets the configuration requirement of the replacement channel, the step of modifying the channel configuration of the node to be cleaned according to the first configuration information is skipped, and the server is directly started.
in the embodiment, the server checks whether the configuration information matched with the first configuration information of the replacement channel exists or not by acquiring the second configuration information of the historical channel in the historical record, and when the configuration information exists, the channel configuration modification step can be directly skipped, so that the server resources are saved.
in an embodiment, the method for clearing block chain data to stop each node in the block chain and associated services corresponding to each node may include: receiving a data cleaning instruction sent by a terminal, wherein the data cleaning instruction comprises a terminal identifier; acquiring a cleaning authority terminal set, and detecting whether a terminal identifier is matched with a terminal identifier in the cleaning authority terminal set; and when the terminal identification is matched with the terminal identification in the clearing authority terminal set, stopping each node in the block chain and the associated service corresponding to each node. .
Specifically, the clearing authority terminal set is a fixed terminal, an authority list set such as an IP frequency band, and the like, and the terminal identifier is identification information of the data clearing sender terminal, and is included in the data clearing instruction and used for pointing to the data clearing sender terminal. The method comprises the steps that when a server receives a data cleaning instruction sent by a terminal, a terminal identifier contained in the data cleaning instruction is obtained, whether the terminal sending the data cleaning instruction is in a cleaning authority terminal set or not is detected through the terminal identifier, if the terminal sending the data cleaning instruction is in the cleaning authority terminal set, subsequent block chain data cleaning work is started, and namely all nodes in a block chain and associated services corresponding to all the nodes are stopped. In addition, if the terminal sending the data cleaning instruction is not in the cleaning authority terminal set, the identity of the terminal sending the cleaning instruction can be verified.
in this embodiment, the server starts the data cleaning work of the blockchain by detecting whether the terminal sending the data cleaning instruction is matched with the cleaning authority terminal set or not, and when the terminal sending the data cleaning instruction is matched with the cleaning authority terminal set, so that other users without authority are prevented from cleaning the blockchain data, and the safety of the blockchain data is ensured.
in an embodiment, the method for clearing block chain data to stop each node in the block chain and associated services corresponding to each node may include: acquiring the data volume of the data to be cleaned, and judging whether the data volume of the data to be cleaned is larger than a preset value or not; and when the data volume of the data to be cleaned is larger than a preset value, stopping each node in the block chain and the associated service corresponding to each node.
Specifically, the preset value may be a critical value, when the amount of data to be cleaned is greater than the critical value, the operation efficiency of the block chain is significantly reduced, the server detects the amount of data to be cleaned, and determines whether the detected amount of data is greater than the preset value, and when the amount of data to be cleaned is greater than the preset value, the server starts a subsequent block chain data cleaning operation, that is, stops each node in the block chain and associated services corresponding to each node. In addition, a preset period can be set, the server can periodically detect the data volume of the data to be cleaned according to the preset period, and the operation efficiency of the block chain is periodically ensured.
in this embodiment, the server starts the data cleaning operation of the block chain by detecting whether the data amount of the data to be cleaned is greater than the preset value or not, and when the data amount is greater than the preset value, the data cleaning operation can be performed when the data to be cleaned affects the operation efficiency, so that the operation efficiency of the block chain is ensured.
In an embodiment, in the block chain data cleaning method, the server cleans the data to be cleaned in the block chain by stopping each node and associated service in the block chain, deleting a data queue in the sequencing service, deleting the data to be cleaned in the node to be cleaned, newly building a replacement channel, restarting the resource exchange server, and the like. For example, a lot of test data are left in the block chain in the operation process due to data testing and the like, the test data lose effect after being tested, and the test data also affect the operation efficiency of the block chain when processing other data, the server stops each node in the block chain and associated services corresponding to each node, then obtains kafka service in the consensus node, deletes a data queue (topic) in the kafka service, then deletes the test data on the consensus node, the test data (ledger data and transient data) on the endorsement node and on the data node, then newly establishes a replacement channel, adds the replacement channel to the node from which the data is deleted, and starts the resource exchange server. Therefore, the data in the block chain is cleaned, and the block chain data cleaning method improves the block chain operation efficiency.
