The embodiment of the invention provides a disaster recovery switching method and device based on a DNS domain name, electronic equipment and a storage medium. The disaster recovery switching method based on a DNS domain name is used in a production system of a total system. The total system further comprises at least two disaster recovery systems. The method is characterized by comprising the following steps: when a switching trigger signal is detected, sending a domain name switching instruction to a DNS server, so that an IP address corresponding to a target domain name is switched from a first IP address of a first disaster recovery system to a second IP address of a second disaster recovery system; sending a domain name resolution request to the DNS server, wherein the domain name resolution request carries the target domain name; obtaining a second IP address which is returned by the DNS server and corresponds to the target domain name; establishing connection with the second disaster recovery system according to the second IP address. Therefore, rapid switching of a disaster recovery system is achieved, and the situation of access faults is avoided.
Description
technical field [0001] The present application relates to the technical field of computer networks, in particular, to a DNS domain name-based disaster recovery switching method, device, electronic equipment and storage medium. Background technique [0002] Remote disaster recovery provides an environment that can cope with various disasters, allowing business systems to ensure the security of user data and provide uninterrupted application service capabilities in case of emergencies. Based on considerations of construction cost and complexity, enterprises often give priority to core business application systems in the process of building remote disaster recovery systems, while non-core business application systems temporarily or do not plan to design disaster recovery systems. Therefore, in the process of realizing the remote disaster recovery system, in addition to realizing the core data replication and switching scheduling of the disaster recovery system itself, it is als...
