如何在生产环境中自动启动Rails Background Worker

Question

I figured out that I start my background worker manually on Develoment Environment.

My payments/transactions will not get successful if my background worker is not running.

What I have done

I created a Procfile and inside it I have the following such that I this below:

ApplicationName/Procfile

worker: bundle exec rake jobs:work 

Will this actually solve my problem if I deploy my application? And if not, how do I start background worker on Production?

Update

I have been called to order from posted answers the Procfile works only for Heroku . Note that I like to deploy to DigitalOcean . I am using Delayed_Job for my Background Worker, and inside its documentation, it states that we can use the following code on production with the help of bundling "daemons" gem with it.

RAILS_ENV=production script/delayed_job start
RAILS_ENV=production script/delayed_job stop

Is there anyway I can automate this by initilizing it, such that env. pick up the code to execute?

Answer 1

Procfile will work only for heroku. So skip the rest of my answer if you are deploying to Heroku.

How to do it depends on system you are deploying. Most of the modern linux systems (ie Ubuntu) using systemd. So you very likely need to create startup script and put it to /lib/systemd/system/__your_service__.service

Just for example

[Unit]
Description=__Your worker_name__

[Service]
Type=forking
User=__your_user__
WorkingDirectory=__your_working_dir__
Environment=RAILS_ENV=production
PIDFile=__your_working_dir__/tmp/pids/__your_service__.pid
ExecStart=absolute_path_to_bundle exec rake jobs:work 

[Install]
WantedBy=multi-user.target

And afterwards type and you are good :)

sudo systemctl enable __your_service__ && sudo systemctl start __your_service__
