mina-unicorn_systemd

Gem extension for mina-deploy to enable easy setup and deployment of unicorn application server managed via systemd.

Assumptions

This gem assumes that you

  • Are on a Linux system with systemd in /etc/systemd/
  • Are using RVM to manage your Ruby version
  • That the setup task has sudoer or root permissions or that you are running with execution_mode :system and are entering passwords. If your regular user does not have sudo, then you can set the setup_user to the name of a user who does.

Basic installation instructions

  1. Add the following to your Gemfile and make sure that unicorn is available in production environment
group :production do
  gem 'unicorn'
end

group :development do  
  gem 'mina-unicorn_systemd', require: false # not necessary to load this when running rails
end
  1. Change your deploy.rb to include 'mina/unicorn.rb'. Make sure to add after nginx
require 'mina/nginx'
require 'mina/unicorn'

  1. Manually run 'mina unicorn:setup' or invoke from your own setup task to enable all one time tasks.

  2. Once you are ready to enable unicorn run 'mina unicorn:enable' to enable the systemd service (persists across reboots).

  3. To manually restart unicorn after a deploy use 'mina unicorn:restart'.

Customization

To change the unicorn systemd service template and/or the unicorn_conf.rb, run 'mina unicorn:generate'.

By default mina-unicorn_systemd is running unicorn as a user service (systemd --user), but the unicorn service template also includes settings for running as a system service. To enable this, add set :unicorn_system_or_user, 'system' to the top of your deploy.rb.
