$mkdir  sidekiq_playground
$cd sidekiq_playground/

$vim Gemfile

添加一个gem

source "https://rubygems.org"

gem "sidekiq"

新增worker.rb

vim worker.rb

require ‘sidekiq‘

Sidekiq.configure_client do |config|
  config.redis = { db: 1 }
end

Sidekiq.configure_server do |config|
  config.redis = { db: 1 }
end

class OurWorker
  include Sidekiq::Worker

  def perform(complexity)
    case complexity
    when "super_hard"
      sleep 20
      puts "super hard! Really took quite a bit of effort"
    when "hard"
      sleep 10
      puts "hard! That was o bit of work"
    else
      sleep 1
      puts "That wasn‘t a lot of effort"
    end
  end
end

安装redis，启动sidekiq

$sudo apt-get install redis-server
$ bundle exec sidekiq -r ./worker.rb

执行一下

$ bundle exec irb -r ./worker.rb
irb(main):001:0> OurWorker.perform_async("easy")
=> "d40dc832d93f50c00afd2ab4"
irb(main):002:0> OurWorker.perform_async("hard")   //立刻执行
=> "33356c6a0c7cd55047d40670"

irb(main):003:0> OurWorker.perform_in(5,"easy")   //5秒后执行
  => "7a517f4305ff6105aa408b4f"
