Python任务调度模块 – APScheduler 2015年6月11日 by debugo · 14条评论 APScheduler简介 APScheduler是一个Python定时任务框架，使用起来十分方便。提供了基于日期、固定时间间隔以及crontab类型的任务，并且可以持久化任务、并以daemon方式运行应用。目前最新版本为3.0.x。 在APScheduler中有四个组件： 触发器(trigger) 包含调度逻辑，每一个作业有它自己的触发器，用于决定接下来哪一个作业会运行。除了他们自己初始配置意外，触发器完全是无状态的。 作业存储(job store) 存储被调度的作业，默认的作业存储是简单地把作业保存在内存中，其他的作业存储是将作业保存在数据库中。一个作业的数据讲在保存在持久化作业存储时被序列化，并在加载时被反序列化。调度器不能分享同一个作业存储。 执行器(executor) 处理作业的运行，他们通常通过在作业中提交制定的可调用对象到一个线程或者进城池来进行。当作业完成时，执行器将会通知调度器。 调度器(scheduler) 是其他的组成部分。你通常在应用只有一个调度器，应用的开发者通常不会直接处理作业存储、调度器和触发器，相反，调度器提供了处理这些的合适的接口。配置作业存储和执行器可以在调度器中完成，例如添加、修改和移除作业。 你需要选择合适的调度器

I'm running a scheduler using python apscheduler inside web.py framework. The function runserver is supposed to run everyday at 9 a.m but it is inconsistent. It runs most days but skips a day once in a while. Code: import web from apscheduler.schedulers.blocking import BlockingScheduler #Blocking Scheduler #URLs urls = ( '/startscheduler/','index', ) Nightlysched = BlockingScheduler() @Nightlysched.scheduled_job('cron', hour=9) def runserver(): print 2+2 #doing some calculations here #Main function to run the cron JOB if __name__ == "__main__": Nightlysched.start() #stating the job app = web

I have a django application running with uwsgi (with 10 workers) + ngnix. I am using apscheduler for scheduling purpose. Whenever i schedule a job it is being executed multiple times. From these answers ans1 , ans2 i got to know this is because the scheduler is started in each worker of uwsgi. I did conditional initializing of the scheduler by binding it to a socket as suggested in this answer and also by keeping a status in the db, so that only one instance of scheduler will be started, but still the same problem exists and also sometimes when creating a job the scheduler is found not running
