這是我第一次使用神寶石。當我運行命令god terminate它不關閉現有的任務。所以下一次我再次運行神劇本時，它只是雙打。第一次使用神寶石，不關閉魔王
我看到示例腳本Resque有終止流氓產生，但不完全知道如何修改我的腳本。
命令我跑
god -c config/resque.god
god -c config/stale.god
我resque.god文件：
RAILS_ROOT = File.dirname(File.dirname(__FILE__))
God.watch do |w|
w.name = "android_msg"
w.group = "resque-group"
w.interval = 30.seconds
w.start = "cd #{RAILS_ROOT} && rake resque:work QUEUE='android_message'"
w.start_grace = 10.seconds
# 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
God.watch do |w|
w.name = "apn_sender"
w.group = "resque-group"
w.interval = 30.seconds
w.start = "cd #{RAILS_ROOT} && rake apn:sender"
w.start_grace = 10.seconds
# 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
