rufus-scheduler由于独角兽工作者而多次运行调度程序 [英] rufus-scheduler runs scheduler multiple times due to unicorn workers

问题描述

我在rails3项目的/configs/initializers/schedule.rb中安装了设置调度程序，并且工作正常，但是它工作了2次，我认为这是由于独角兽工人同时执行调度程序，所以它在我的系统中创建数据库每次有两个记录. 我检查了逻辑及其确定，然后在本地计算机中输入了一条记录.

I had setup scheduler in my rails3 projects's /configs/initializers/schedule.rb and it working fine, But it works 2 times and I think it is due to unicorn workers execute schedule at the same time, so it create in my database two records each time. I checked my logic and its ok and enter single record in my local machine.

我检查了以下内容，但不知道如何阻止多个独角兽工作者执行调度程序?

推荐答案

尝试一下

require 'rufus-scheduler'

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

unless scheduler.down?

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