Rufus调度程序与独角兽一起运行多次，并通过:lockfile修复，但是如何消除错误味精?

问题描述

scheduler = Rufus::Scheduler.new :lockfile => ".rufus-scheduler.lock"

scheduler.every("60") do
...
end

环境:Ubuntu，rails 4，rufus，独角兽，nginx

Environment: Ubuntu, rails 4, rufus, unicorn, nginx

独角兽有多个工作人员，因此上述每一项"任务将每60秒执行多次.

Unicorn has multiple workers, so the above 'every' task will be executed multiple times every 60 seconds.

根据这一答案: rufus调度程序每次运行两次，我添加了:lockfile选项，它有效！

According to the answer for this one: rufus scheduler running twice each time, I added :lockfile option, and it works!

但是，从日志来看，似乎每个"任务仍然试图被调用，从而导致出现许多错误消息:

However, from the log, it seems that the 'every' task still tries to be called, resulting in a lot of error messages:

E, [2014-05-09T01:59:47.496840 #2747] ERROR -- : cannot schedule, scheduler is down or shutting down (Rufus::Scheduler::NotRunningError)
/home/sohmobile/shared/bundle/ruby/2.1.0/gems/rufus-scheduler-3.0.7/lib/rufus/scheduler.rb:605:in `do_schedule'

/home/sohmobile/releases/20140509014407/config/initializers/task_scheduler.rb:3:in `<top (required)>'

我该如何解决这个问题?

How can I solve this issue?

谢谢.

推荐答案

这可以解决您的问题:

require 'rufus-scheduler'

scheduler = Rufus::Scheduler.new(:lockfile => ".rufus-scheduler.lock")

unless scheduler.down?

  scheduler.every("60") do
    # ...
  end
end
