我在生产网站上使用 Resque。
当我部署时，我希望 GOD 停止所有工作人员然后重新启动它们，因为有时我们会更改类的代码并将失败的作业重新排队。
问题是，当我做上帝停止 resque 时，耙子实际上并没有停止，工人仍然活着并使用旧代码，这给我带来了各种各样的问题。
即使我“上帝终止”它也不会杀死工人。
现在，我正在使用一个 shell 脚本来杀死工作人员，但是由于我有不止一台服务器，所以在所有生产服务器上进行操作非常痛苦。
这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
对于如何停止使用 GOD 进行耙工作，我将不胜感激。
谢谢。
