Problems solved by technology

Although the multi-node software system provides additional redundancy, it does not solve the problem of recovery after a failure of a certain device node in the system. Now the method of manual recovery is generally adopted. After the software of a certain device fails, restart install the software
And because the operation commands to the software are often more complex, and many configuration requirements included may need to be adjusted continuously, so it is difficult to restore it to the state before the failure simply by manual recovery, and it may also cause other failures

Abstract

An embodiment of the present application discloses a failure recovery method and a device for a first device. The method includes: recording an operation command generated by operating a target software, and sending the operation command to a second device; If the target software fails, the operation command sent by the second device is received and executed to recover the target software. The method comprises: acquiring an operation command sent by a first device, the operation command being a command generated by operating target software in the first device; if the target software fails, the operation command is sent to the first device to enable the first device to recover the target software by executing the operation command.

Description

technical field [0001] The present application relates to the field of computers, in particular to a fault recovery method and device. Background technique [0002] Because the traditional single-node hardware system does not have redundant equipment to provide backup, its service will be greatly affected after a failure occurs. With the advancement of computer technology, a multi-node operating software system has appeared, and different devices are regarded as different. Installing the same software on different devices can ensure that after the software on one device fails, the software on other devices can still provide services. Although the multi-node software system provides additional redundancy, it does not solve the problem of recovery after a failure of a certain device node in the system. Now the method of manual recovery is generally adopted. After the software of a certain device fails, restart Install the software. And because the operating commands for the ...
