上帝停止resque工人耙

當我部署時，我希望GOD停止所有的工作人員，然後重新啓動他們，因爲有時我們會更改類的代碼並請求失敗的作業。

問題是，當我做上帝停止resque，耙子實際上並沒有停止，工人仍然活着，並與舊的代碼工作，這爲我造成各種各樣的問題。

即使我做'上帝終止'它不會殺死工人。

現在，我正在使用shell腳本來殺死工作人員，但由於我有更多的服務器，所以在所有的生產服務器上執行這些操作都非常痛苦。

這是我的上帝配置文件：

rails_env = ENV['RAILS_ENV'] || "production" 
rails_root = ENV['RAILS_ROOT'] || "/mnt/data-store/html/gogobot/current" 
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 = 2.minutes 
    w.env  = {"QUEUE"=>"duplicate_merging,facebook_wall_posts,generic,mailer,notifications,realtime,scoring_system,signup,social_graph_facebook,social_graph_foursquare,social_graph_twitter,user_info,user_score", "RAILS_ENV"=>rails_env, "PIDFILE" => "#{rails_root}/tmp/resque_#{w}.pid"} 
    w.pid_file = "#{rails_root}/tmp/resque_#{w}.pid" 
    w.start = "cd #{rails_root}/ && rake environment resque:work QUEUE=duplicate_merging,facebook_wall_posts,generic,mailer,notifications,realtime,scoring_system,signup,social_graph_facebook,social_graph_foursquare,social_graph_twitter,user_info,user_score RAILS_ENV=#{rails_env}" 
    w.log  = "#{rails_root}/log/resque_god.log" 

    w.uid = 'root' 
    w.gid = 'root' 

    # restart if memory gets too high 
    w.transition(:up, :restart) do |on| 
     on.condition(:memory_usage) do |c| 
     c.above = 350.megabytes 
     c.times = 2 
     end 
    end 

    # determine the state on startup 
    w.transition(:init, { true => :up, false => :start }) do |on| 
     on.condition(:process_running) do |c| 
     c.running = true 
     end 
    end 

    # determine when process has finished starting 
    w.transition([:start, :restart], :up) do |on| 
     on.condition(:process_running) do |c| 
     c.running = true 
     c.interval = 5.seconds 
     end 

     # failsafe 
     on.condition(:tries) do |c| 
     c.times = 5 
     c.transition = :start 
     c.interval = 5.seconds 
     end 
    end 

    # start if process is not running 
    w.transition(:up, :start) do |on| 
     on.condition(:process_running) do |c| 
     c.running = false 
     end 
    end 
    end 
end 

1.times do |num| 
    God.watch do |w| 
    w.name  = "dj-#{num}" 
    w.group = 'dj' 
    w.interval = 30.seconds 
    w.start = "cd #{rails_root} && rake jobs:work" 

    w.uid = 'root' 
    w.gid = 'root' 

    # retart if memory gets too high 
    w.transition(:up, :restart) do |on| 
     on.condition(:memory_usage) do |c| 
     c.above = 300.megabytes 
     c.times = 2 
     end 
    end 

    # determine the state on startup 
    w.transition(:init, { true => :up, false => :start }) do |on| 
     on.condition(:process_running) do |c| 
     c.running = true 
     end 
    end 

    # determine when process has finished starting 
    w.transition([:start, :restart], :up) do |on| 
     on.condition(:process_running) do |c| 
     c.running = true 
     c.interval = 5.seconds 
     end 

     # failsafe 
     on.condition(:tries) do |c| 
     c.times = 5 
     c.transition = :start 
     c.interval = 5.seconds 
     end 
    end 

    # start if process is not running 
    w.transition(:up, :start) do |on| 
     on.condition(:process_running) do |c| 
     c.running = false 
     end 
    end 
    end 
end

會喜歡我怎麼能使用GOD停止耙作業任何幫助。

謝謝。

的解決方案是將SIGQUIT發送給該進程因此，例如，你可以運行

god signal resque SIGQUIT
