A DNS service deployment method and system for overall coordinated scheduling

Abstract

The invention relates to a DNS service deployment method and system for overall coordinated scheduling. This method maintains the services carried by the entire analysis cluster, resource allocation, and the roles and associations of all servers; then performs association, priority, dependency, and exclusion analysis on the adjustment of service information, judges the feasibility of service adjustment, and decomposes it into reliable operations Steps and operation sequence; then, according to the operation sequence, the specific operation steps are sent to the analysis server cluster, the operation result is verified, and the wrong operation is left, suspended or rolled back. The system includes a service information maintenance and adjustment 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. The invention can realize automatic execution of DNS cluster service deployment and service change, reduce service change risk, and ensure convenient, orderly and correct execution of service change operation.

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
