我正在尝试创建一个自定义守护程序以每 60 秒运行一次并使用 bluepill 启动/停止和监视它。
有人可以告诉我如何更容易地做到这一点,或者请你告诉我我做错了什么?
目前,bluepill 正在启动守护程序以便它运行,但似乎不知道它正在运行,因为它一直在尝试停止和启动它。
这是我的 .pill 文件中的代码
app.process("get_dropboxes") do |process|
process.working_dir = RAILS_ROOT
process.pid_file = File.join(RAILS_ROOT, "tmp", "pids", "get_dropbox.pid")
process.start_command = "/usr/bin/env RAILS_ENV=#{RAILS_ENV} bundle exec lib/daemons/get_dropbox_ctl start"
process.stop_command = "/usr/bin/env RAILS_ENV=#{RAILS_ENV} bundle exec lib/daemons/get_dropbox_ctl stop"
process.start_grace_time = 10.seconds
process.stop_grace_time = 10.seconds
process.restart_grace_time = 10.seconds
process.checks :cpu_usage, :every => 30.seconds, :below => 20, :times => [3,5]
process.checks :mem_usage, :every => 30.seconds, :below => 350.megabytes, :times => [3,5]
end
这是我的 get_dropbox_ctl 文件
#!/usr/bin/env ruby
require 'rubygems'
require "daemons"
require 'yaml'
require 'erb'
gem 'activesupport', '>=3.0.0'
require 'active_support'
# For some reason, ActiveSupport 3.0.0 doesn't load.
# Load needed extension directly for now.
require "active_support/core_ext/object"
require "active_support/core_ext/hash"
options = YAML.load(
ERB.new(
IO.read(
File.dirname(__FILE__) + "/../../config/daemons.yml"
)).result).with_indifferent_access
options[:dir_mode] = options[:dir_mode].to_sym
Daemons.run File.dirname(__FILE__) + "/get_dropbox.rb", options
这是我的 get_dropbox.rb 文件
#!/usr/bin/env ruby
# You might want to change this
ENV["RAILS_ENV"] ||= "production"
require 'net/pop'
require File.dirname(__FILE__) + "/../../config/application"
Rails.application.require_environment!
$running = true
Signal.trap("TERM") do
$running = false
end
while($running) do
# do stuff .......
sleep 60
end
我得到的日志

肯定有比这更简单的方法吗?
