Dual-computer hot standby method for vehicle information management system based on VRRP

Abstract

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. Including steps 1) Configuring dual-system hot standby parameters; 2) Establishing a hot standby relationship between the active server and the standby server; 3) The server with a higher priority enters the active state and periodically sends heartbeat messages; 4) The active server real-time Periodically or periodically, the business data is synchronized to the backup server in the form of data synchronization messages through the FTP file transfer protocol; 5) After receiving the data synchronization messages and FTP data, the backup server immediately updates the database information; 6) When the main server appears When restarting or when the vehicle information management service provided by the primary server fails, the backup server enters the primary state; 7) After the primary server recovers, take the initiative to obtain the business data on the backup server from the backup server, and resume providing vehicle information management services.

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...
