'parse_rackup_file': rackup file (config.ru) not readable (ArgumentError) about mina-unicorn

[tab]

Put config.ru file on root directory of your Rails project, example for Rails-4 application

# This file is used by Rack-based servers to start the application.

require ::File.expand_path('../config/environment',  __FILE__)
run Rails.application

@tab Thanks for getting back to me. I already have that in my config.ru file in the root of my app. I'm guessing Unicorn can't find it?

[jmccartie]

Got it.

Another tutorial had me setting my working_directory to /home/deployer/my_app ... it should have been /home/deployer/my_app/current

Thanks for your help!

@jmccartie, I'm glad to see you got it!

By the way you can use this unicorn.rb config file, it work with Rails-3 and Rails-4 applications.

# Set your full path to application.
app_dir = File.expand_path('../../', __FILE__)

# Set unicorn options
worker_processes 2
preload_app true
timeout 360

# Fill path to your app
working_directory app_dir

# Set up socket location
listen "#{app_dir}/tmp/sockets/unicorn.sock", :backlog => 64

# Loging
stderr_path "#{app_dir}/log/unicorn.stderr.log"
stdout_path "#{app_dir}/log/unicorn.stdout.log"

# Set master PID location
pid "#{app_dir}/tmp/pids/unicorn.pid"

before_fork do |server, worker|
  defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect!
  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      sig = (worker.nr + 1) >= server.worker_processes ? :QUIT : :TTOU
      Process.kill(sig, File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection
end

before_exec do |server|
  ENV['BUNDLE_GEMFILE'] = "#{app_dir}/Gemfile"
end
