Rufus cron Planung funktioniert nicht auf einem Steg Server

Question

Schritte zu replizieren:

1. ein neues Rails-Projekt erstellen. (Schienen 3.2.22.5)
2. hinzufügen Abhängigkeiten (warbler, Harke, rufus-Scheduler) (/ Gemfile)
3. JRuby 9.1.7.0
4. neue Dateien erstellen. (/config/warble.rb) (/web.xml.erb) (/config/intializers/scheduler_rufus.rb)
5. Erstellen Sie eine ausführbare WAR-Datei mit Steg-Webserver. (Warble War RAILS_ENV = Entwicklung)
6. Starten Sie die ausführbare Datei. (java -jar mywar.war)
7. Der Scheduler führt den Cron-Job nicht aus.

Answer 1

Sie sagen "es ist nicht planen". Ich schätze, du hast bis zur angegebenen 1815 gewartet, aber nichts ist passiert.

Nach Ihrer vorherigen Frage (Why is Rufus scheduling the job twice?) ist rufus-scheduler eigentlich planen, also was passiert?

Der Rufus-Scheduler 3.3.3 (den Sie scheinbar verwenden) verwendet standardmäßig die Zeitzone von Rails. Diese Zeitzone wird in der Datei config/application.rb und standardmäßig auf UTC gesetzt.

Konnte es sein, dass Sie bis 1815 Ortszeit (nicht UTC-Zeit) gewartet haben und nichts passiert ist?

Versuchen Sie mit einem Zeitplan wie (jede Minute) oder "*/5 * * * *" (0, 5, 10, 15, ... Minute).

Answer 2

@jmettraux hat es genagelt.

/config/application.rb

config.time_zone = 'Eastern Time (US & Canada)' 

/config/initializers/scheduler_rufus.rb

require 'rufus-scheduler' 

scheduler = Rufus::Scheduler.singleton 

unless defined?(Rails::Console) || File.split($0).last == 'rake' 
    # only schedule when not running from the Ruby on Rails console 
    # or from a rake task 

    scheduler.every '10s' do 
     puts Time.now.strftime("%d/%m/%Y %H:%M") 
    end 

    scheduler.cron '52 19 * * *' do 
     puts 'Hello World' 
    end 
end
