Я использую развертывание приложения Ruby on Rails на Linode VPS с использованием Capistrano.Я использую Unicorn в качестве сервера приложений и Nginx в качестве прокси.Моя проблема в том, что я не могу запустить Unicorn из-за явной проблемы с разрешениями, но мне трудно отследить ее.
Unicorn запускается с помощью этой задачи Capistrano:
task :start, :roles => :app, :except => { :no_release => true } do
run <<-CMD
cd #{current_path} && #{unicorn_bin} -c #{unicorn_config} -E #{rails_env} -D
CMD
end
Я возвращаюсь и ArgumentError указывает, что путь к файлу pid недоступен для записи.

Наконец, вот соответствующие разделы моего файла конфигурации Unicorn (unicorn.rb)
# Ensure that we're running in the production environment
rails_env = ENV['RAILS_ENV'] || 'production'
# User to run under
user 'deploy', 'deploy'
# We will spawn off two worker processes and one master process
worker_processes 2

# This is where we specify the socket.
# We will point the upstream Nginx module to this socket later on
listen "/home/deploy/apps/shared/sockets/unicorn.sock", :backlog => 64

# Set the path of the log files
stderr_path "/home/deploy/apps/gogy/current/log/unicorn.stderr.log"
stdout_path "/home/deploy/apps/gogy/current/log/unicorn.stdout.log"
Я развертываю с Capistrano под пользователем и группой 'deploy', и под этим также должен работать Unicorn.
Есть ли у кого-нибудь идеи, почему Unicorn не может выписать pid-файл?Любая помощь будет принята с благодарностью !!!
