配置： puma_server_conf.rb

#!/usr/bin/env puma

application_path = '/srv/rorapps/discount_service'
directory application_path
environment 'development'
daemonize true
pidfile "#{application_path}/tmp/pids/puma_4000.pid"
state_path "#{application_path}/tmp/pids/puma_4000.state"
stdout_redirect "#{application_path}/log/puma_4000.stdout.log", "#{application_path}/log/puma_4000.stderr.log"

port 4000
workers 8

启动开关：puma.sh

#! /usr/bin/env bash
current_path=`cd "$(dirname "$0")"; pwd`
. $current_path/function.sh

puma_file=$current_path/../puma_conf/puma_service_4000.rb
puma_pid=$current_path/../../tmp/pids/puma_4000.pid

echo "######### info #############"
echo "PUMA DISCOUNT SERVICE 4000"
echo "## $puma_file ## $puma_pid ##"
echo "############################"

case "$1" in
  start)
    puma -C $puma_file
    echo "puma_service_4000 start ............... $(command_status)"
  ;;
  status)
    check_run_status_from_pid_file $puma_pid 'puma'
  ;;
  stop)
    kill -s SIGTERM `cat $puma_pid`
    echo "puma_service_4000 stop ................ $(command_status)"
  ;;
  restart)
    # $0 stop
    # sleep 1
    # $0 start
    kill -s SIGUSR2 `cat $puma_pid`
  ;;
  *)
    echo "tip:(start|stop|restart|status)"
    exit 5
  ;;
esac
exit 0

初始文件：

rails_env=`ruby $current_path/parse_property.rb RAILS_ENV`

processor_pid=$MRS_DATA_PATH/pids/sidekiq.pid
log_file=$MRS_DATA_PATH/logs/sidekiq.log

start:
create_file $processor_pid
create_file $log_file

parse_property.rb

require "yaml"

yaml: MRS_DATA_PATH : $HOME/DISCOUNT_SERVICE_DATA   RAILS_ENV : development
config = YAML.load_file(File.expand_path("../property.yaml",__FILE__))

if "MRS_DATA_PATH" == key
  `mkdir -p #{value}/logs`

  `mkdir -p #{value}/pids`
end

puts `echo #{value}`
