Puma перезапускается при каждом втором развертывании

0 голосов
/ 06 апреля 2019

Я следовал Развертывание приложения Rails в Ubuntu 14.04 с Capistrano, Nginx и Puma с некоторыми незначительными изменениями в Ubuntu 18.0.4, но файлы конфигурации остались теми же.

Теперь, когда я заново разверну, используя 

cap production deploy

первый раз заканчивающиеся журналы, как это 

01:38 deploy:cleanup
      Keeping 5 of 6 deployed releases on 157.230.160.164
      01 rm -rf /home/deploy/apps/ezlarm-server/releases/20190406115244
    ✔ 01 deploy@157.230.160.164 1.543s
01:48 puma:restart
      01 ~/.rvm/bin/rvm default do bundle exec pumactl -S /home/deploy/apps/ezlarm-server/shared/tmp/pids/puma.state -F /home/deploy/apps/ezla…
      01 Command restart sent success
    ✔ 01 deploy@157.230.160.164 2.206s
01:52 deploy:log_revision
      01 echo "Branch master (at 0a06a0f61268848284c00bbbd47ee038f8daf2bf) deployed as release 20190406123158 by faisal-nfl" >> /home/deploy/a…
    ✔ 01 deploy@157.230.160.164 1.118s
Skipping task `puma:restart'.

и при доступе к серверу происходит сбой чем при повторном развертывании,

конечные журналы похожи на это 

01:21 deploy:cleanup
      Keeping 5 of 6 deployed releases on 157.230.160.164
      01 rm -rf /home/deploy/apps/ezlarm-server/releases/20190406115458
    ✔ 01 deploy@157.230.160.164 1.069s
01:28 puma:make_dirs
      01 mkdir /home/deploy/apps/ezlarm-server/shared/tmp/sockets -p
    ✔ 01 deploy@157.230.160.164 1.192s
      02 mkdir /home/deploy/apps/ezlarm-server/shared/tmp/pids -p
    ✔ 02 deploy@157.230.160.164 1.188s
01:34 puma:start
      using conf file /home/deploy/apps/ezlarm-server/shared/puma.rb
      01 ~/.rvm/bin/rvm default do bundle exec puma -C /home/deploy/apps/ezlarm-server/shared/puma.rb --daemon
      01 Puma starting in single mode...

    ✔ 01 deploy@157.230.160.164 2.544s
01:40 deploy:log_revision
      01 echo "Branch master (at 0a06a0f61268848284c00bbbd47ee038f8daf2bf) deployed as release 20190406123406 by faisal-nfl" >> /home/deploy/a…
    ✔ 01 deploy@157.230.160.164 1.039s
Skipping task `puma:restart'.

и все начинает работать нормально.

Это происходит при каждом развертывании, например, если одно не работает, а второе работает

мой файл deploy.rb похож на этот

set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')
set :bundle_binstubs, nil

        puts "Run `git push` to sync changes."
        exit
      end
    end
  end

  desc 'Initial Deploy'
  task :initial do

  end

  before :starting,     :check_revision
  after  :finishing,    :compile_assets
  after  :finishing,    :cleanup
  after  :finishing,    :restart
end

# ps aux | grep puma    # Get puma pid
# kill -s SIGUSR2 pid   # Restart puma
# kill -s SIGTERM pid   # Stop puma

Я не знаю, почему это работает после каждого сбоя.
