Method for recovering main and standby systems of gateway server

Abstract

The invention provides a method for recovering main and standby systems of a gateway server, and belongs to the field of system upgrading. The method is characterized by comprising the steps that a main uboot program and a standby uboot program are set, meanwhile, a main kernel and a main file system corresponding to the main uboot program are set, and a standby kernel and a standby file system corresponding to the standby uboot program are set; wherein the main uboot program is set to be unable to be upgraded, the flash is read-only, and the standby uboot program, the main kernel, the main file system, the standby kernel and the standby file system are all set to be able to be upgraded. According to the method and the device, the problem that the system cannot be restarted due to incomplete system on the flash caused by accidental power failure or other accidents in the upgrading process can be prevented.

Description

technical field [0001] The invention relates to a system upgrade technology, in particular to a recovery method of a gateway server master and standby system. Background technique [0002] In the context of the Internet age, any place needs to be connected to the Internet. The simplest example is a home wireless router, which is the main back-end device for accessing the Internet. Once the system cannot be started normally, the home network will not be able to work normally. For network equipment with high requirements, such as commercial premises, once the network is interrupted, production activities such as cash register, inventory check, and member system search will be affected, and the loss is immeasurable. [0003] The existing system is a single uboot and a single kernel, so the problem is that if the user accidentally cuts off the power during the upgrade process, the system cannot be started normally because the system has not been upgraded.

Problems solved by technology

The simplest example is a home wireless router, which is the main back-end device for surfing the Internet. Once the system fails to start normally, it will cause the home network to fail to work normally.

High requirements such as network equipment in commercial places, once the network is interrupted, it will affect the production activities such as cash register, inventory check, and membership system search, and the loss is immeasurable

[0003] The existing system is a single uboot and a single kernel, so the problem is that if the user accidentally cuts off the power during the upgrade process, the system cannot be started normally because the system has not been upgraded.
