我已经为此苦苦挣扎了一段时间,启动 resque 和 resque 调度程序等后台进程的正确方法是什么?使用上帝是不是矫枉过正?

目前我正试图让上帝工作,但我不确定 *.god conf 文件是否应该在应用程序的目录或其他地方。

这就是我使用的:

config
 |- app.god
 |- God
   |- resque.god
   |- resque_scheduler.god

# config/god/resque.god
rails_env   = ENV['RAILS_ENV']  || raise(ArgumentError, "RAILS_ENV not defined")
rails_root  = ENV['RAILS_ROOT'] || File.expand_path(File.join(File.dirname(__FILE__), '..', '..'))
num_workers = rails_env == 'production' ? 5 : 2

num_workers.times do |num|
  God.watch do |w|
    w.dir      = "#{rails_root}"
    w.name     = "resque-#{num}"
    w.group    = 'resque'
    w.interval = 30.seconds
    w.env      = {"QUEUE"=>"*", "RAILS_ENV"=>rails_env, "BUNDLE_GEMFILE"=>"#{rails_root}/Gemfile"}
    w.start    = "/usr/bin/rake -f #{rails_root}/Rakefile environment resque:work"
    w.log      = "#{rails_root}/log/resque-scheduler.log"

    ... start/stop methods  ...
  end
end

有一个 root 用户和一个 MyApp 用户。MyApp 用户有一个应用程序位于:/home/myapp/apps/myapp_production/current

我使用的 God capistrano 食谱是:

# config/deploy.rb
after "deploy:restart", "god:restart"

namespace :god do
  def try_killing_resque_workers
    run "pkill -3 -f resque"
  rescue
    nil
  end

  desc "Restart God gracefully"
  task "restart", :roles => :app do
    god_config_path = File.join(release_path, 'config', 'app.god')
    begin
      # Throws an exception if god is not running.
      run "cd #{release_path}; bundle exec god status && RAILS_ENV=#{rails_env} RAILS_ROOT=#{release_path} bundle exec god load #{god_config_path} && bundle exec god start resque"

      # Kill resque processes and have god restart them with the newly loaded config.
      try_killing_resque_workers
    rescue => ex
      # god is dead, workers should be as well, but who knows.
      try_killing_resque_workers

      # Start god.
      run "cd #{release_path}; RAILS_ENV=#{rails_env} bundle exec god -c #{god_config_path}"
    end
  end
end

当我部署时,我得到“服务器不可用(或者您没有访问它的权限)”

奇怪的是,当我什至以 root 身份登录并运行god status它时,它什么也不返回,但如果我运行god --version它,它会返回版本。

有谁知道为什么?

您是否设置了 init.d 脚本?你有上帝在运行吗?

/etc/init.d/god status

您可以尝试手动启动它

/usr/bin/god -c /etc/god/conf.god -D

并检查日志
