Ruby on rails 为什么puma暂存环境不启动？

当我尝试在

staging

环境中启动web服务器时，它不会运行。 但在与配置相同的

生产环境中，一切正常

错误在哪里

我的puma配置为：

deploy_to = ENV['CURRENT_PATH']

workers Integer(ENV['PUMA_WORKERS'] || 3)
threads Integer(ENV['MIN_THREADS']  || 16), Integer(ENV['MAX_THREADS'] || 16)
daemonize       true
preload_app!
backlog = Integer(ENV['PUMA_BACKLOG'] || 20)

directory       "#{deploy_to}/current"
pidfile         "#{deploy_to}/shared/tmp/pids/puma.pid"
state_path      "#{deploy_to}/shared/tmp/sockets/puma.state"
stdout_redirect "#{deploy_to}/shared/log/puma.stdout.log", "#{deploy_to}/shared/log/puma.stderr.log"
bind            "unix://#{deploy_to}/shared/tmp/sockets/kiosk.sock"
activate_control_app "unix://#{deploy_to}/shared/tmp/sockets/pumactl.sock"


on_worker_boot do
  # worker specific setup
  ActiveSupport.on_load(:active_record) do
    config = ActiveRecord::Base.configurations[Rails.env] ||
                Rails.application.config.database_configuration[Rails.env]
    config['pool'] = ENV['MAX_THREADS'] || 16
    ActiveRecord::Base.establish_connection(config)
  end
end

当您尝试在
staging
中启动时，会出现哪一个错误？@Vasfed更新postI意味着rails的日志，很可能是
log/staging.log
，或者在控制台中，根据您的日志设置，似乎存在与puma无关的内容itself@Vasfed哦，对不起，顺便说一下，
staging.log
为空尝试在没有puma的情况下启动
rails服务器-e staging
，以确保rails能够在staging中运行（db和其他配置等）
