Method for dual-computer hot-standby of vehicle information management system on basis of VRRP

Abstract

The invention provides a method for dual-computer hot-standby of a vehicle information management system on the basis of a VRRP and relates to a dual-computer hot-standby method. The method is suitable for a system having important data storage. The method comprises a first step of configuring dual-computer hot-standby parameters; a second step of enabling a main server and a standby server to establish hot-standby relations; a third step of enabling a server high in priority to enter a main use state, and periodically sending heartbeat messages; a fourth step of enabling the main server to synchronize service data to the standby server in real time or periodically through an FTP file transfer protocol in a data synchronization message mode; a fifth step of enabling the standby server to receive data synchronization messages and FTP data, and instantly updating database information; a sixth step of enabling the standby server to enter a main use state when the main server is restarted or faults occur in vehicle information management services provided by the main server; a seventh step of enabling the main server to actively obtain service data on the standby server when the main server recovers, and starting to provide the vehicle information management services again.

Description

technical field [0001] The invention relates to a dual-system hot backup method for a vehicle information management system based on VRRP, which is suitable for a system with important data storage. Background technique [0002] In the vehicle management information system, the vehicle-mounted device uploads the vehicle's trajectory and working condition data to the vehicle management information server in time. It also increases rapidly, but the performance of the CPU and I / O of the server is always limited, and it cannot cope with the problem of a sharp decline in service quality caused by the rapid increase in concurrent access requests from a large number of terminals, which can easily lead to service stoppages or even failures. Failures such as restarting will cause great economic losses. In order to avoid economic losses caused by server access failures, the security and reliability of the server is particularly important. Contents of the invention [0003] The pur...
