Question

我安装了delayed_job，并启动守护程序以使用此Ruby脚本运行作业：

require 'rubygems'
require 'daemon_spawn'
$: << '.'

RAILS_ROOT = File.expand_path(File.join(File.dirname(__FILE__), '..'))

class DelayedJobWorker < DaemonSpawn::Base
  def start(args)
    ENV['RAILS_ENV'] ||= args.first || 'development'
    Dir.chdir RAILS_ROOT
    require File.join('config', 'environment')

    Delayed::Worker.new.start
  end

  def stop
    system("kill `cat #{RAILS_ROOT}/tmp/pids/delayed_job.pid`")
  end
end

DelayedJobWorker.spawn!(:log_file => File.join(RAILS_ROOT, "log", "delayed_job.log"),
                    :pid_file => File.join(RAILS_ROOT, 'tmp', 'pids', 'delayed_job.pid'),
                    :sync_log => true,
                    :working_dir => RAILS_ROOT)

如果我使用rvmsudo运行该命令，则效果非常好。

如果我只使用没有RVM的Ruby命令就会失败，这就是输出。我不知道为什么会这样。你能给我一些线索吗？

Answer 1

您有权限问题。

简单地说：你有一个延迟的工作在另一个用户下运行（由于使用root而可预测rvmsudo），并且守护程序spawn试图杀死它。您将获得Operation not permitted。

首先尝试使用rvmsudo终止delayed_job，确保它没有运行（尝试ps aux），然后尝试在没有rvmsudo的情况下启动。

它应该有用。

Answer 2

首先，看看shared / pids / delayed_job.pid，看看进程是否正在运行。在我的情况下，看起来它被关闭了不洁，并且pid文件留在原地。部署脚本试图杀死不存在的进程并且正在提供该权限错误。

我删除了delayed_job.pid并成功部署。

为什么没有RVM我的delayed_job会失败？
