Debian rails Puma god 开机启动

whitek

　　1、安装 god

gem install god

2、设置环境变量 以及开机启动的rc.local 文件 ，其内容如下

PATH=$PATH:/zhiyisoft/bin god -c /etc/god/god.god

备注： 请将 ruby bin目录下的所有文件链接到 /zhiyisoft/bin 下面，否则将无法运行

如果是  rvm ，请执行下方命令
  1、 rvm wrapper 2.0.0@rails3 boot up god
  2、 /usr/local/rvm/bin/bootup_god  或者 $HOME/.rvm/bin/bootup_god 替换rc.local

3、创建 /etc/god/god.god文件

rails_env = ENV['RAILS_ENV'] || 'development'
rails_root = ENV['RAILS_ROOT'] || "/zhiyisoft/app/phonebook"
project_name = "phonebook"

# 以上部分为配置，请根据情况修改

God.watch do |w|
w.name = "#{project_name}"
  w.interval = 30.seconds # default

  w.start = "cd #{rails_root} && bundle exec puma --config #{rails_root}/config/puma.conf -e #{rails_env} -d; echo $?;"

  w.stop = "kill -TERM `cat #{rails_root}/tmp/puma.pid`"

  w.restart = "kill -USR2 `cat #{rails_root}/tmp/puma.pid`"

  w.start_grace = 10.seconds
  w.restart_grace = 10.seconds
  w.pid_file = "#{rails_root}/tmp/puma.pid"

  w.uid = "root"
  w.gid = "root"

  w.behavior(:clean_pid_file)

  w.start_if do |start|
    start.condition(:process_running) do |c|
      c.interval = 5.seconds
      c.running = false
    end
  end

  w.restart_if do |restart|
    restart.condition(:memory_usage) do |c|
      c.above = 300.megabytes
      c.times = [3, 5] # 3 out of 5 intervals
    end

    restart.condition(:cpu_usage) do |c|
      c.above = 50.percent
      c.times = 5
    end
  end
  # lifecycle
  w.lifecycle do |on|
    on.condition(:flapping) do |c|
      c.to_state = [:start, :restart]
      c.times = 5
      c.within = 5.minute
      c.transition = :unmonitored
      c.retry_in = 10.minutes
      c.retry_times = 5
      c.retry_within = 2.hours
    end
  end
end

God.watch do |w|
  w.dir = "#{rails_root}"
w.name = "#{project_name}_clear"
  w.interval = 60.seconds
  w.env = {"RAILS_ENV"=>rails_env}

  w.uid = 'root'
  w.gid = 'root'

  w.start = "bundle exec rake daemon:clear_queue"
  w.keepalive
end

4、项目里面创建 config/puma.conf 其内容如下

rails_env = ENV['RAILS_ENV'] || 'development'

threads 4,16

#bind  "unix:///tmp/puma.sock"
bind "tcp://0.0.0.0:9090"
pidfile "/tmp/pid"
state_path "/tmp/state"

activate_control_app

备注 ：此文件需要按需调整
