god doesn't stop unicorn - ruby

Question

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

Answer 1

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
