[0146] b) Send the DNS configuration file, configuration file version list, and operation parameters to the intelligent operation module.

[0147] A. DNS configuration file format: specify the NS record of the DNS server IP in the DNS module and the A record of the NS record; the resolution record of the domain name;

[0148] Example:

[0149] a.com NS ns1.a.com

[0150] a.com NS ns2.a.com

[0151] ns1.a.com A 1.1.1.1 (Note: A record of NS record)

[0152] ns2.a.com A 2.2.2.2 (Note: A record of NS record)

[0153] www.a.com A 3.3.3.3

[0154] mail.a.com A 4.4.4.4

[0155] Remarks: By changing the A record of the NS record in the DNS configuration file, the disaster recovery switch of the DNS server can be realized; by modifying the A record of the domain name, the disaster recovery switch of the Web Server IP can be realized.

Abstract

The present invention provides a method and system for handling faults in a domain name system. The computer network is involved; the problem of low efficiency and accuracy in the configuration file error discovery and processing scheme is solved. The method includes: obtaining the version of the DNS configuration file currently loaded by the DNS server; detecting whether the version of the DNS configuration file currently loaded by the DNS server matches the latest DNS configuration file version of the configuration management platform; If the above DNS server fails, start automatic troubleshooting. The technical solution provided by the invention is suitable for the maintenance of the configuration file of the domain name system, and realizes the automatic detection and processing of the abnormality of the configuration file.

Description

technical field [0001] The invention relates to a computer network, in particular to a domain name system (DNS) fault handling method and system. Background technique [0002] As the entrance of the current Internet, DNS plays an important role in the process of network access. In order to improve the resolution efficiency of the DNS system and enhance the robustness of the system, in addition to the DNS protocol itself supporting the cluster protocol, some DNS systems adopt anycast or marginalization and other architectures. Whether it is an adaptive clustering protocol, or anycast and edge architecture, the complexity and scale of the DNS system have been greatly increased. [0003] With the development of the Internet, users have higher and higher requirements for network access experience, and how to realize the automatic disaster recovery backup of the DNS server is also an important part of it. How to realize the automatic disaster recovery backup of the DNS server i...
