The IPFS SyncServer in each node can read a file information list from a database, and the IPFS SyncServer in each node carries out a data synchronous storage request by sending a ping command to the local IPFS. When the first node goes down, the second node automatically becomes a main node, so that the application is uninterrupted, and the normal operation of the application can be ensured.
After receiving the service request, the first node can analyze the service request and determine evidence information, evidence storage files and block chain identifiers from evidence storage data, and store the evidence storage files to a local IPFS, the second node, the third node and the fourth node all need to search a file information list every n seconds from a MySQL database through a local IPFSSyncServer, check evidence storage file records, obtain the evidence storage file identifiers and hash values corresponding to the evidence storage files from the file information list, convert a plurality of bits before the hash values into integers to obtain numerical values, then divide the numerical values by 4 to obtain the remainder, calculate the absolute value of the remainder, judge whether the remainder is equal to the node identifiers, if the remainder is equal, send ping requests to the IPFS through the local IPFS SyncServer, and synchronously store the evidence storage files, or, it may be determined whether the remainder is 1 smaller than the local identifier, and special processing is performed when the remainder is 3, so that the current node synchronizes the certificate storage file, that is, when the remainder is 2, the node two and the node three synchronously store the certificate file, and when the remainder is 3, the node three and the node synchronously store the certificate file. After the node synchronously stores and stores the certificate file successfully, the synchronous certificate storing file identification, the hash value corresponding to the certificate storing file, the node identification, the timestamp and other information can be recorded in the MySQL database, and the scanned file certificate storing identification recorded by the node certificate storing can be updated.
The network redundancy of the IPFS may be set to 2, or may be 3 or 4, that is, the same data is stored in two, three or four partitions on the blockchain node in the network, so as to prevent data loss caused by a failure of a certain node.
Furthermore, block chains of different categories, such as Chainsql and Hyperhedge Fabric, run in the four nodes, each block Chain corresponds to a unique block Chain identifier and a transaction data structure, and the first node can forward the certificate storing information to the Common Chain Api through the apiserver, so that the Common Chain Api can store the hash value corresponding to the certificate storing file and the certificate storing transaction corresponding to the certificate storing information encapsulation block Chain identifier, and synchronously store the certificate storing transaction to the block Chain corresponding to the block Chain identifier in each node, and if the certificate storing transaction is stored in the Chainsql, the safety of data storage is ensured based on the characteristic that the block Chain data cannot be tampered.
In this embodiment, each node can interact with the database and the local distributed file system by calling the distributed storage synchronization service, so as to determine whether to synchronize the storage certificate file to the local distributed file system, prevent the data from being lost due to a single-point fault, and upload the storage certificate information to the block chain, so that the data cannot be tampered randomly, and further ensure that the data storage is safer.
In addition, in the present application, a unified Common link interface Common Chain Api is preinstalled in each node, and by integrating SDKs of multiple blockchain platforms and unifying the SDKs into a Restful Api interface in an upper layer design, a user can call the Common Chain Api through the unified Api interface without additional other operations when accessing each blockchain, so that the Common Chain Api identifies the blockchain according to a request after receiving a client request, thereby calling the SDK corresponding to the blockchain and packaging data into transactions corresponding to the blockchain, thereby implementing data uplink storage and improving uplink efficiency of storing certified data.
Optionally, each node in the high-density server may be monitored, operated and maintained through the background management end. The monitoring service may collect information of system hardware resources, such as cpu, memory, hard disk, and the like, and the other part is to detect the availability of each service, and the monitoring service may acquire the information at regular time and then store the information in the database of the master node. The operation and maintenance comprises functions of updating configuration information related to the block chain or adding and deleting nodes and the like. The administrator enters the operation and maintenance function by logging in a client interface, and can send an instruction through the apiserver, and the instruction calls CommonChain Api to change the SDK related to the block chain after logic judgment is carried out on the instruction through the apiserver. Each node corresponds to a shell script, and the background management end can realize the operation and maintenance function by calling the shell script.
Local nodes in the high-density server can be connected with block chain link points at the cloud end in two connection modes: one is a block chain link point connection local node of the cloud; and the other type is a block chain node of which the local node is connected with the cloud. When the block chain link points of the cloud are connected with the local nodes, a user needs to add port mapping of the local block chain link nodes on the front-end router of the server, and the fact that the points of the block chain of the cloud can access the local nodes is guaranteed; when the local node is connected with the block chain link point of the cloud, a user needs to modify part of network configuration information in the node block chain on an operation and maintenance interface, so that the local node can access the block chain node of the cloud through external network connection. The local node is connected with the block chain link points of the cloud, so that the block chain service range is wider.
