Method for realizing fault migration through virtual host and virtual host service device

Abstract

The application discloses a virtual host service device and a method for realizing fault migration through the same. The method comprises the following steps: searching a second server with a free resource through a resource control module for controlling virtual host service in a unified manner when a virtual host is in fault and a first server to which the virtual host belongs cannot realize disaster recovery, and establishing a new virtual host in the second server and updating service route; and migrating the service on the virtual host in fault to the new virtual host according to a downloaded configuration file and the updated service route. The data migration and user intervention are unnecessary in the migration of the virtual host disclosed by the application; the service can be directly transferred to the new virtual host only according to the updated route after the virtual host is successfully established; the traffic is directly cut so that the subsequent access is performed on the migrated virtual host resource; and zero interrupt of the service is realized. Thus the seamless migration of the fault is simply and flexibly realized, and the reliable operation of the user service is guaranteed.

Description

technical field [0001] The present application relates to virtual host technology, in particular to a method for virtual host to realize fault migration and a virtual host service device. Background technique [0002] Virtual hosting (virtual hosting) refers to the virtualization technology of web servers such as apache and nginx to provide an operating environment for web pages. [0003] At present, virtual hosts are multiplexed based on a single physical device, that is, the virtual host on the corresponding physical device is resolved directly through the A address (Address) or CNAME. The resulting problem is that when the user's virtual host is attacked or fails, it can only be migrated to another physical device. With the migration of the virtual host, the user's IP address and temporary domain name will change, which will cause the interruption of the user's business. At this time, the user needs to manually configure the A address or CANME again. After the new record...

AI Technical Summary

Problems solved by technology

[0004] In this way, when the virtual host is attacked or down, failover cannot be achieved; and it is also not convenient to support the virtual host to dynamically adjust the resource size and operating environment

It can be seen that because the existing virtual host cannot span the resources of a single machine and equipment, its computing resources are limited to the resources of one server, and it is impossible to break through the bottleneck of single computing

It is precisely because the virtual host is limited by the resources of a single physical machine that its business processing capability is greatly restricted, and the maximum computing power cannot exceed the computing power of a single machine.
