Abstract

The invention provides a distributed timed task execution method and system, can realize distributed cluster execution of timed tasks, and can completely solve the problem of single-point failure and task repetitive execution, and thus the system availability is high. The distributed timed task execution method comprises the following steps: a system cluster module keeps long connection with registered server nodes and generates a server list; a task distributing module distributes a server to each received timed task according to the server list and stores the binding relationship between the timed tasks and the servers to a database; a task loading module periodically scans a timed task table in the database and loads the timed tasks about to be executed in the period to the server, and establishes a timed task; and a task execution module executes the timed task.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and system for executing distributed timing tasks. Background technique [0002] In the Linux environment, Crontab technology is usually used to perform timing tasks. This command reads instructions from the standard input device and stores them in the "crontab" file for later reading and execution. Usually, the instructions stored in crontab are activated by the daemon process, and crond often runs in the background, checking every minute whether there is a scheduled job that needs to be executed. However, this technical solution has a single point of failure problem, that is, if the crontab process is working abnormally or the server itself is down, the scheduled task will not be executed on time; if multiple linux servers are used to configure the same crontab task, the same task will exist For problems that are repeatedly executed, locks must be used in specific b...
