Overall cooperative scheduling type DNS service deployment method and system

Abstract

The invention relates to an overall cooperative scheduling type DNS service deployment method and system. The method comprises the following steps: maintaining a role and incidence relation of services born by a whole analysis cluster, resource allocation and all servers; then performing association, priority, dependence and exclusion analysis on the adjustment of service information, judging the feasibility of service adjustment, and decomposing the service adjustment into reliable operation steps and an operation time sequence; then releasing the specific operation steps to a server cluster according to the operation time sequence, verifying the operation result, and carrying out retaining, pausing or rolling back and other processing on wrong operations. The system comprises a service information maintaining and adjusting unit, a service adjustment analysis and decomposition unit, a service deployment scheduling processing unit, a configuration management and version control unit and an analysis server cluster. By adoption of the overall cooperative scheduling type DNS service deployment method and system, the automatic execution of DNS cluster service deployment and service change can be realized, the service change risk is reduced, and convenient, orderly and correct execution of the service change operations is ensured.

Description

technical field [0001] The invention belongs to the automatic deployment technology for distributed resolution systems in the field of computer networks, and in particular relates to a DNS service deployment method and system for overall coordinated scheduling. Background technique [0002] The resolution system is an important infrastructure of the Internet, mainly responsible for the conversion between domain names and IP addresses. At present, the more important distributed analysis systems are deploying dozens to hundreds of analysis nodes in many places to ensure the security and stability of analysis services. [0003] The existing service deployment technology of analysis nodes mainly relies on delivering software and configuration to the analysis server, and implementing the deployment by completing specified operation commands. The main problems are as follows: [0004] a) It is characterized by deploying a single type of resolution service for one or several resol...

AI Technical Summary

Problems solved by technology

[0004] a) It is characterized by deploying a single type of resolution service for one or several resolution nodes, and lacks system coordination in scenarios where resolution clusters provide multiple services (such as providing top-level domain services, second-level authoritative services, recursive services, etc.) scheduling considerations;

[0005] b) Only the service deployment operation of local nodes is considered, and there is a lack of consideration of change risks and optimization schemes during the simultaneous service change process of multiple parsing servers
