在初始化程序中设置 rabbitmq 连接时

#config/initializers/rabbitmq.rb
$rabbitmq_connection = Bunni.new "amqp://#{user}:#{pass}@#{host}:#{port}#{vhost}"
$rabbitmq_connection.start
$rabbitmq_channel = $rabbitmq_connection.create_channel

从我尝试创建交换和发布的地方抛出超时错误

class Publisher
...
  exchange = $rabbitmq_channel.topic 'some', {auto_delete: false, passive: true}
end

如果直接在 Publisher 中创建连接和通道而不是工作。

class Publisher
  ...
  $rabbitmq_connection = Bunni.new "amqp://#{user}:#{pass}@#{host}:#{port}#{vhost}"
  $rabbitmq_connection.start
  $rabbitmq_channel = $rabbitmq_connection.create_channel
  ...
end

彪马设置

#config/deploy.rb
set :puma_workers, 4
set :puma_threads, [4, 16]
set :puma_init_active_record, true
set :puma_bind, %w(tcp://0.0.0.0:9291 tcp://0.0.0.0:9292 unix:///home/deployer/project/current/tmp/sockets/puma.sock)

在我的情况下，我应该如何初始化连接并创建通道？谢谢
