Scheduler not Running - Passenger + Nginx

[codyrickmanvessel]

Hello, I have seen a lot of older threads on this but none of the solutions have worked for me. I am having the classic issue of the scheduler not running when deployed to production with Nginx and Passenger.

System:

CentOS 7
rails 5.1.6
ruby 2.5.3
rufus-scheduler 3.6.0

passenger.conf

passenger_root /usr/share/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/bin/ruby;
passenger_instance_registry_dir /var/run/passenger-instreg;
passenger_spawn_method direct;
passenger_min_instances 1;
passenger_pool_idle_time 0;

app.conf

server {
    listen 3000;
    server_name localhost;

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /home/user/app/public;

    # Turn on Passenger
    passenger_enabled on;
    passenger_ruby /usr/local/rvm/gems/ruby-2.5.3/wrappers/ruby;
}

sheduler.rb

require 'rufus-scheduler'
scheduler = Rufus::Scheduler.new

scheduler.every '1h' do
  //Some Task
end

Is there something I am missing of another passenger parameter I need to try? Thank You.

Sorry, did you find any help in the Passenger forum?

[jmettraux]

Could you please indicate what version of Passenger and what version of Nginx you're using (update your question text).

I am reading the Passenger documentation right now so I need to know.

[jmettraux]

Have you tried passenger_pre_start to make sure Passenger does not sit idle while waiting the first request?

[jmettraux]

No answer. Closing.

Hi, I thought I was having a problem with rails + passenger + nginx, so I googled everywhere for a solution and found this issue. Though it turns out it was just misconfiguration on my part (I think) since the jobs are executing now.

I'm not really sure if rufus-scheduler works out of the box with rails + passenger + nginx now, since the stackoverflow questions seem to be a few years old now. In any case my scheduled jobs work fine (some every 4 hours, some daily), without configuring nginx/passenger. I'll continue to observe if the scheduler works as expected.

In any case I'll just leave this here in case something goes wrong:
https://stackoverflow.com/a/28062602

rails_app_spawner_idle_time 0;
passenger_min_instances 1;

https://stackoverflow.com/a/36791451

passenger_spawn_method direct;
passenger_min_instances 1;
passenger_pool_idle_time 0;

My setup for reference:
Operating System: Ubuntu 18 LTS
Phusion Passenger 6.0.2
nginx version: nginx/1.14.0
rails (4.2.6)
rufus-scheduler (3.6.0)
