god doesn't stop unicorn

god, ruby, ruby-on-rails-3, unicorn

Solution

Now we are using foreman and puma right now...this is our initializer: ` web: bundle exec puma -q -d -e production -b 'unix:///home/api/shared/web.socket' -S /home/api/shared/web.state --control 'unix:///home/api/shared/web.ctl' `

and deploying with capistrano, so that we can stop and restart the server like this

config/deploy.rb

# Puma commands
_cset(:puma_cmd) { "#{fetch(:bundle_cmd, 'bundle')} exec puma" }
_cset(:pumactl_cmd) { "#{fetch(:bundle_cmd, 'bundle')} exec pumactl" }
_cset(:puma_state) { "#{shared_path}/puma.state" }
_cset(:puma_role) { :app }

# Puma
namespace :puma do

  desc 'Start puma'
  task :start do
    run "cd #{current_path} ; bundle exec foreman start web"
  end

  desc 'Stop puma'
  task :stop, :roles => lambda { fetch(:puma_role) }, :on_no_matching_servers => :continue do
    run "cd #{current_path} && #{fetch(:pumactl_cmd)} -S #{fetch(:puma_state)} stop"
  end

  desc 'Restart puma'
  task :restart, :roles => lambda { fetch(:puma_role) }, :on_no_matching_servers => :continue do
    run "cd #{current_path} && #{fetch(:pumactl_cmd)} -S #{fetch(:puma_state)} restart"
  end
end

Problem

I have this file ``` rails_env = ENV['RAILS_ENV'] || 'development' rails_root = ENV['RAILS_ROOT'] || "/home/luiz/rails_dev/api" God.watch do |w| w.name = "unicorn" w.interval = 30.seconds # default # unicorn needs to be run from the rails root w.start = "cd #{rails_root} && unicorn_rails -c config/unicorn.rb -E #{rails_env}" # QUIT gracefully shuts down workers w.stop = "kill -QUIT `cat #{rails_root}/tmp/pids/unicorn.pid`" # USR2 causes the master to re-create itself and spawn a new worker pool w.restart = "kill -USR2 `cat #{rails_root}/tmp/pids/unicorn.pid`" w.start_grace = 10.seconds w.restart_grace = 10.seconds w.pid_file = "#{rails_root}/tmp/pids/unicorn.pid" w.behavior(:clean_pid_file) w.start_if do |start| start.condition(:process_running) do |c| c.interval = 5.seconds c.running = false end end w.restart_if do |restart| restart.condition(:memory_usage) do |c| c.above = 300.megabytes c.times = [3, 5] # 3 out of 5 intervals end restart.condition(:cpu_usage) do |c| c.above = 50.percent c.times = 5 end end # lifecycle w.lifecycle do |on| on.condition(:flapping) do |c| c.to_state = [:start, :restart] c.times = 5 c.within = 5.minute c.transition = :unmonitored c.retry_in = 10.minutes c.retry_times = 5 c.retry_within = 2.hours end end end ``` I start unicorn with `god -c unicorn.god -D -p 8081` and my workers are setup fine. but, sometimes I need do stop unicorn (`god stop unicorn -p 8081` in another console) but the server keep up and running. what am I missing? Edit We're moving from unicorn to puma (not because this question, it's a performance thing), and not going to use god anymore...thanks everybody for your help
