为play工程写一个状态管理的脚本并且随机启动

step1.先写脚本啦，废话不说，代码如下：
#!/bin/bash
### BEGIN INIT INFO
# Provides:          Frank Ting
# Required-Start:    $network $local_fs $remote_fs
# Required-Stop::    $network $local_fs $remote_fs
# Should-Start:      $all
# Should-Stop:       $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Baccy-router
# Description:       Baccy-router
### END INIT INFO
PID=”$(cat /var/lib/projects/baccy-router-1.0-SNAPSHOT/RUNNING_PID)” 
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
start(){
    if [ -z $PID ]
    then
      /var/lib/projects/baccy-router-1.0-SNAPSHOT/bin/baccy-router -Dhttp.port=9090&
      echo “baccy-router is starting”
      return 0
    else
      echo “baccy-router already started “
      return 1
    fi
}

stop(){
    kill $PID
    echo “baccy-router is stopping”
    PID=””
}

status(){
    if [ -z $PID ]
    then
     echo “baccy-router is  not running”
    else
     echo “baccy-router is running”
    fi
}
case “$1” in
   start)
start
;;

   stop)
stop
;;
   restart)
stop
start
;;
   status)
status
;;
   *)
echo “Usage: {start|stop|restart|status}”
exit 1
esac

exit 0
step2.移动到/etc/init.d目录下，名字我改成baccy-router，然后增加执行权限
<span class="pln">chmod </span><span class="lit">755</span><span class="pln"> baccy</span><span class="pun">-</span><span class="pln">router</span>
<span class="pln">mv baccy</span><span class="pun">-</span><span class="pln">router  </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">init</span><span class="pun">.</span><span class="pln">d</span>
<span class="pln">/etc/init.d/baccy-router start</span>
<span class="pln">/etc/init.d/baccy-router status
</span>
<span class="pln">/etc/init.d/baccy-router restart
</span>
step3.加入到linux服务中，就可以随机启动啦
<span class="pln">insserv </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">init</span><span class="pun">.</span><span class="pln">d</span><span class="pun">/</span><span class="pln">baccy</span><span class="pun">-</span><span class="pln">router</span>
<span class="pln">reboot</span>
PS:也可以往linux计划（crontab ）里添加进程检查策略，详情请咨询google。
