Errno::ENOENT: 没有这样的文件或目录 - connect(2) for home/ubuntu/GlucoMeDDC/shared/tmp/sockets/puma.sock

Question

我正在使用 Capistrano 3 部署我的 rails 应用程序，并从 Puma gem 中收到此错误：

bundler: failed to load command: puma (/home/ubuntu/GlucoMeDDC/shared/bundle/ruby/2.4.0/bin/puma)

puma stderr: Nothing written

我在这里寻找答案，但没有一个对我有帮助。 例如，如果我这样做 puma:config 它将起作用，但使用 DEFAULT Puma 配置，而不是从我的 puma.rb 文件中获取，即使我添加了 conf 指向给它。

这是我的 deploy.rb：

lock '3.10.1'

set :application, 'GlucoMeDDC'
set :repo_url, 'git@github.com:user/GlucoMeDDC.git' # Edit this to match your repository
set :branch, ENV['BRANCH'] if ENV['BRANCH']
set :user, 'ubuntu'
set :deploy_to, '/home/ubuntu/GlucoMeDDC'
set :pty, true
set :linked_files, %w{config/application.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system public/uploads}
set :keep_releases, 5
append :rvm_map_bins, 'puma', 'pumactl'
set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.4.1' # Edit this if you are using MRI Ruby

# set :puma_rackup, -> { File.join(current_path, 'config.ru') }
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock"   #accept array for multi-bind
set :puma_conf, "#{current_path}/config/puma.rb"
set :puma_access_log, "#{shared_path}/log/puma_access.log"
set :puma_error_log, "#{shared_path}/log/puma_error.log"

namespace :puma do
  desc 'Create Directories for Puma Pids and Socket'
  task :make_dirs do
    on roles(:app) do
      execute "mkdir #{shared_path}/tmp/sockets -p"
      execute "mkdir #{shared_path}/tmp/pids -p"
    end
  end

  before :start, :make_dirs
end

namespace :deploy do

  desc 'Initial Deploy'
  task :initial do
    on roles(:app) do
      before 'deploy:restart', 'puma:start'
      invoke 'deploy'
    end
  end


desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      invoke! 'puma:restart'
    end
  end

  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

任何提示我还能做什么？

Answer 1

我很确定我以前遇到过这种情况，这是由于错误中引发的路径中缺少文件夹/错误权限造成的。 IE。 tmp 和/或 sockets 文件夹丢失或无法访问：

... home/ubuntu/GlucoMeDDC/shared/tmp/sockets/puma.sock ...

仔细检查这些是否按预期创建。看起来它们应该是，尽管在哪里定义了 shared_path - 这绝对正确吗？

否则，请检查文件夹和文件的权限以确保它们正确无误。您可以运行ls -la 来检查这一点，并根据需要进行调整。

希望其中有帮助 - 渴望听到您的反馈。

Answer 2

该问题可能是由错误的puma_bind 引起的。应该是：

set :puma_bind, "unix:///#{shared_path}/tmp/sockets/puma.sock"

Answer 3

据我尝试，没有办法在 puma.rb 和 deploy.rb 中配置 puma。 所以我只是在 deploy.rb 中做了所有配置，它运行良好。谢谢大家的回答和cmets。
