Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the drawings required to be used in the embodiments will be briefly described below, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

A method for automatically deploying a block chain network based on an intelligent contract is characterized in that public and private key encryption is adopted for signature, and the result is verified in validity by the intelligent contract. Firstly, dividing a user into a common account and an audit account to realize the permission of deployment requirements; meanwhile, each account has a pair of public and private keys, and the public keys are stored in a system block chain, so that the property of non-tampering is ensured; when the common account submits the deployment requirement application, the application information is signed by using a private key of the common account, so that the reliability of the application information is ensured; the auditing account signs the application result of the deployment requirement according to the requirement, so that the specialty and the uniqueness of auditing are ensured, and the possibility of unauthorized deployment is avoided; and the system intelligent contract automatically judges whether the deployment requirement is legal or not according to the auditing result of the auditing account, if so, a corresponding deployment program is started, a corresponding node is started according to the templated information in the deployment application, finally, the deployment result is written into the system block chain, and the corresponding success or failure information is pushed to related deployment personnel to complete the automatic deployment of the block chain system.

FIG. 1 is a flow chart of an embodiment. The specific implementation steps are as follows:

the method comprises the following steps: building deployment management platform

Initializing a service server of x86_64 type, installing docker and docker-compound basic software, and operating all the services in the manner of docker in the later period. Servers are divided into two major types: the system server and the business server, wherein the user server is used for deploying all corresponding blockchain networks, and the system server is used for deploying the management platform and managing all the business servers at the later stage.

And loading the component mirror image of the block chain network to be deployed in the later stage on the service server to form a basic condition. And later, a corresponding container is constructed on the service server directly based on the images, so that the executable program is executed to process the service request. Meanwhile, a management platform is installed on the system server, the management platform is also a block chain system with an intelligent contract function, and the intelligent contract is realized by a high-level language and has the capability of accessing a network. In order to distinguish the intelligent contract running on the business server, the intelligent contract becomes a system intelligent contract. The system intelligent contract can realize the automatic deployment of the block chain system in the later period.

Step two: adding audit accounts and common accounts

In order to ensure the safe and stable operation of the system, users need to be classified: the system comprises a common account and an audit account, wherein the common account has the permission to deploy the block chain system, and the audit account has the permission to audit the common account applying for deploying the system. The flow is controllable through the cooperation of the two authorities.

Besides basic information such as user name, account level, adding time and the like, the account information is added with the information of the user public key, namely, each account is provided with a unique public and private key. When a user is added to the management platform, the corresponding public key needs to be carried to the platform and stored in the account book of the system block chain platform, and the private key is kept in an offline environment by the user, so that the absolute security of the account is ensured. The later-stage system platform performs signature verification on all requests by using the public keys stored in the system block chain account book, so that the correctness of all requests is guaranteed from the aspect of mathematic verifiability, and illegal behaviors such as deployment request forgery and tampering are avoided.

Step three: deploying system intelligence contracts

The intelligent contract is a section of automatically executed logic code, the execution logic of the intelligent contract only needs to accord with the pre-designed rule and can be automatically executed without human intervention, and meanwhile, the execution result of the intelligent contract stores the required information in the block chain account book through consensus. The intelligent contract of the system is installed on the management platform, the main content of the intelligent contract is to execute due verification, and after the verification is passed, the deployment of the block chain network is realized according to the requirement. Meanwhile, all execution requests and results are stored in the account book, so that full tracing of the deployment process can be realized in the later stage, and a more convenient and faster tracing function is provided for operation and maintenance.

Step four: common user proposes deployment requirement application

If the common user needs to deploy the block chain network, the common user cannot directly deploy the block chain network on the service server through the deployment platform due to the authority management criteria, and basic information such as the deployment requirement and the purpose of the common user needs to be submitted to the management system platform, so that whether the deployment is supported or allowed by an auditor is absolutely required.

The requirements application will template the deployment information, i.e. fill in part of the mandatory fields, including: the method comprises the following steps of deployment type, the number of deployment nodes, service server addresses corresponding to the nodes and access passwords of the service servers. When a common user submits the deployment requirement application, the deployment information needs to be signed by using the own private key stored in the offline environment, and the signed information is attached to the requirement application and submitted together.

Step five: auditor auditing deployment application

The auditor receives the deployment requirement application information proposed by the common user, and starts to audit the application information, and the main flow is as follows:

1) according to the applicant in the application information, a public key of the applicant is retrieved from the system block chain, the signature of the deployment information is verified, if the verification fails, the possibility of applying for disguising exists, and the deployment requirement is directly rejected; if the verification is successful, the second step is executed.

2) And analyzing the deployment template information to obtain the corresponding deployment requirement. And confirming whether the server information in the deployment requirement can meet the deployment requirement, if not, rejecting the deployment requirement, otherwise, confirming the deployment requirement and checking to pass.

3) And the auditor signs the audit result by using the own private key, continues to attach the audit result to the application requirement information and submits the application requirement information to the system block chain.

Through the three steps of processes, the auditor finishes the application and audit of the deployment requirement, and the accuracy of the information and the possibility of later deployment are fully ensured.

Step six: system intelligent contract automation deployment network

After receiving the auditing result submitted by the auditor, the system intelligent contract begins to analyze the result and executes corresponding actions:

1) obtaining public key information of an auditor from the block chain system, checking whether signature information of the auditor is correct, if the signature information is wrong, indicating that the audit is not the audit result of the auditor, directly abandoning the requirement, and directly writing the result into the block chain, wherein the state is marked as an 'illegal request'; if the verification is correct, executing the second step;

2) checking the auditing result, if the result is rejected, not starting a deployment process, directly writing the result into a block chain, and marking the state as 'rejected deployment'; if the data are unified, executing a third step;

3) analyzing the deployment template information one by one, acquiring corresponding service server access passwords, remotely starting corresponding block chain nodes one by one according to the types of the deployment nodes, and finally completing networking of all the nodes to realize deployment of a block chain network; if all the nodes are deployed successfully, writing the result into the block chain, marking the state as 'deployment successful', and turning to the fifth step; if the deployment fails due to network and other reasons, directly increasing 1 by the deployment frequency recorder of the node, and executing the fourth step;

4) firstly, checking a deployment recorder of the node, if the deployment recorder reaches an upper limit value (prefabricated in a system intelligent contract), judging that deployment fails, writing a result into a block chain, marking a state as 'deployment failure', and turning to a fifth step; if the network connectivity does not reach the upper limit value, starting to detect the network connectivity, turning to the third step after the network is recovered, and trying again;

5) the deployment management platform monitors the account information of the system block chain, analyzes the corresponding deployment result information in the block after the deployment result of the deployment request is accounted, and pushes the information to the corresponding common user, so that an actual deployer can obtain the corresponding deployment result.
