in a distributed system, a plurality of hosts form a network cluster through asynchronous communication. In such an asynchronous system, state replication between hosts is required to ensure that each host has consistent state consensus. The invention provides a server cluster file synchronization method which is based on a block chain, adopts a block chain architecture and is applied to an electronic device 40. Fig. 1 is a schematic diagram of an application environment of a server cluster file synchronization method according to a preferred embodiment of the present invention.

The first computer device 110 and the second computer device 120 may be connected through bluetooth, USB (universal serial Bus), or other communication connection methods, which is not limited herein.
Fig. 2 is a flowchart of server cluster file synchronization according to the present invention, in this embodiment, the server cluster file synchronization process includes the following steps:
s110: each server host is taken as a host node to carry a server cluster, each host node in the carried server cluster is in a decentralized point-to-point distributed block chain network established through a TCP protocol, and the online state of the host node is ensured among the host nodes in the server cluster through a heartbeat mechanism.
When each server host is taken as a host node to carry a server cluster, each host node in the server cluster acquires IP identity information of adjacent peer host nodes, and then the acquired identity information of each host node is recorded into the server cluster according to a predefined structure of an X.509 certificate by adopting a block chain distributed account book technology;
IP identity information data of all hosts in the server cluster are stored on each host node of the server cluster;
the IP identity information of each host in the server cluster at least includes: host model, asset number, and host configuration information.
The heartbeat mechanism regularly sends a self-defined structure body to each host node, the structure body comprises a heartbeat packet or a heartbeat frame, the heartbeat packet or the heartbeat frame is sent every few minutes, the heartbeat packet or the heartbeat frame is generally fixed information, and when each host node receives the fixed information, one piece of fixed information is replied to the server cluster. If the server cluster receives the fixed information reply, the host node is considered to be in a connection state or an online state, and the connection is judged to be effective; if the server cluster does not receive the fixed information reply and is regarded as disconnected, the host node is judged to be invalid in connection, namely the host node which does not receive the fixed information reply is an invalid connection node and needs to be reconnected; if a certain host node is always in an offline state according to a heartbeat mechanism among the host nodes in the server cluster, an alarm is sent to the client side, and reconnection needs to be initiated manually.
after the embarkation of the server cluster is completed, the method proceeds to step S120: collecting data change information or data modification information of a change host in the server cluster, and integrating the data change information and the data modification information generated by the change host into a file module, wherein the change host is a host node with data change or data modification in the server cluster; the file module is a collection of changes and data modifications that occur to a single host node, the change host.
after the integration of the document modules is completed, the process proceeds to step S130: carrying out validity verification on the file module based on an asymmetric encryption algorithm;
The process of carrying out validity verification on the file module based on the asymmetric encryption algorithm comprises the following steps:
establishing a key authentication system for the changed host based on an asymmetric encryption algorithm;
the key authentication system judges the validity of the file module, if the data change or data modification in the file module is legal, a consensus mechanism is triggered to carry out consensus voting, and if the data change or data modification in the file module is illegal, an alarm request is sent out to stop file synchronization;
The process of judging the validity of the file module by the key authentication system comprises the following steps:
The change host generates a public-private key pair, and separates the public-private key pair to form a public key and a private key;
the public key is adopted to change or modify and encrypt the data in the file module and then add the data to each host node in the server cluster;
an information transmission channel is established at least based on any one of a DUBBO protocol, a TCP protocol and an HTTP protocol, a private key is transmitted through the information transmission channel, the private key is adopted to decrypt data change information or data modification information encrypted by the public key, and when decryption is successful, the file module is judged to be legal.
after the validity verification, the process proceeds to step S140: and carrying out consensus voting based on a consensus algorithm on the file modules passing the legality verification, and triggering a preset intelligent contract when the found consensus is greater than or equal to a preset proportion.
and carrying out consensus voting based on a consensus algorithm on the file modules passing the legality verification, wherein the consensus proportion is preset in advance in the process of triggering the intelligent contract when the consensus reaches the preset consensus proportion, the file modules passing the legality verification can trigger the intelligent contract only when the consensus reaches the consensus proportion, and a warning is sent to stop the file synchronization if the consensus does not reach the consensus proportion.
The consensus algorithm is generally a rule, each host node screens out the most representative data according to the rule, and in the blockchain network, various screening schemes exist, including: in this embodiment, the rule is to vote on a file module that passes the validity verification, screen out an appropriate file module, and make all host nodes in the server cluster keep data consistent.
After triggering the preset intelligent contract, the method proceeds to step S150: and completing the synchronization of the server cluster file and the file module according to the triggered intelligent contract.
The triggered intelligent contract calls a contract program to complete the synchronization of the server cluster file and the file module, and the process may include:
triggering an intelligent contract preset in the block chain network to start a contract program;
autonomously detecting data change information or data modification information in the file module through the contract program, and starting a data synchronization program;
Enabling each host node in the server cluster and the change host to generate consistent data change or data modification through the data synchronization program;
the changing host is authenticated and validated by each host node in the blockchain network.
The server cluster file refers to IP identity information and other related data of all host nodes in the whole server cluster, the file module refers to data change or data modification generated by the change host, and the server cluster file is consistent with the file module in order to ensure that all the host nodes in the whole server cluster generate the same data change or data modification as the change host.
In the server cluster file synchronization method in this embodiment, after a server cluster is carried on based on a block chain network, data change and data modification occurring in a change host are integrated into a file module, then validity verification is performed on the file module based on an asymmetric encryption algorithm, consensus voting is performed on the file modules passing the validity verification, and then an intelligent rule is triggered to complete synchronization of the whole server cluster file and the file module; when one computer is changed or data is modified, each computer is not required to be logged in to modify corresponding configuration or data, and the efficiency of completing server cluster file synchronization by coping with a change host can be greatly improved.
