Puma

Question

所以，我正在尝试使用 Capistrano 部署 Sinatra 应用程序。我已成功部署应用程序，但无法启动 Puma。当我输入应用程序的 current 目录和运行 pumactl -F config/puma.rb start 时，出现以下错误：

ubuntu@ip-10-0-0-195:/srv/apps/cx/current$ pumactl -F config/puma.rb start
[18512] Puma starting in cluster mode...
[18512] * Version 4.3.5 (ruby 2.5.1-p57), codename: Mysterious Traveller
[18512] * Min threads: 2, max threads: 6
[18512] * Environment: staging
[18512] * Process workers: 1
[18512] * Phased restart available
No such file or directory - connect(2) for /srv/apps/cx/releases/shared/tmp/sockets/puma.sock

我不知道它在 cx/releases 目录中的查找方式或原因。我在下面附上了我的一些文件，也许有人可以告诉我我做错了什么。

Puma.rb

# Change to match your CPU core count
workers 1

# Min and Max threads per worker
threads 2, 6

app_dir = File.expand_path('../../..', __FILE__)
shared_dir = "#{app_dir}/shared"

# Default to production
rails_env = ENV['RAILS_ENV'] || 'staging'
environment rails_env

# Set up socket location
bind "unix://#{shared_dir}/tmp/sockets/puma.sock"

# Logging
stdout_redirect "#{shared_dir}/logs/puma.stdout.log", "#{shared_dir}/logs/puma.stderr.log", true

daemonize

# Set master PID and state locations
pidfile "#{shared_dir}/pids/puma.pid"
state_path "#{shared_dir}/pids/puma.state"
activate_control_app

on_worker_boot do
  require 'active_record'
  ActiveRecord::Base.connection.disconnect! rescue ActiveRecord::ConnectionNotEstablished
  ActiveRecord::Base.establish_connection(YAML.load_file("#{app_dir}/current/config/database.yml")[rails_env])
end

lowlevel_error_handler do |ex, env|
  Raven.capture_exception(
    ex,
    message: ex.message,
    extra: { puma: env },
    transaction: 'Puma'
  )
  # note the below is just a Rack response
  [500, {}, ['An error has occurred, and engineers have been informed. Please reload the page']]
end

    } # managed by Certbot
    listen 80;
    server_name staging.lmdelivers.com;
    return 404; # managed by Certbot
}

如您所见，我没有在任何地方调用 /releases 目录。如果有人能让我指出正确的方向，我将非常感激。

谢谢

Answer 1

试试这个

app_dir = File.expand_path('../../../..', __FILE__)

此外，套接字路径在一个配置文件中设置为.../tmp/puma.sock，在另一个配置文件中设置为.../tmp/sockets/puma.sock。

Puma - 没有这样的文件或目录 - connect(2)。不知道它从哪里得到这个位置

Puma - No such file or directory - connect(2). No idea where it's getting this location from

ruby

nginx

sinatra
