raspbian（Ubuntu）通过init.d的方式配置开机启动脚本

```
#!/bin/bash

# /etc/init.d/MyShell

### BEGIN INIT INFO

# Provides: abc

# Required-Start: $remote_fs

# Required-Stop: $remote_fs

# Default-Start: 2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: ledblink initscript

# Description: This service is used to manage a led

### END INIT INFO

case "$1" in

start)

echo "update route"

route del default gw 172.16.22.254

route add default gw 172.16.22.254 metric 256

route add -net 118.178.0.0  netmask 255.255.0.0 gw 192.168.20.1

echo "Starting abc"

java -jar /home/pi/Downloads/abc.jar &

;;

stop)

echo "Stopping abc"

process='abc'

pid=$(ps x | grep $process | grep -v grep | awk '{print $1}')

kill $pid

;;

*)

echo "Usage: service daemon start|stop"

exit 1

;;

esac

exit 0

```

1.将shell脚本保存至/etc/init.d/ 目录下
/etc/init.d/MyShell start
/etc/init.d/MyShell stop
2.配置开机自动执行
添加： sudo update-rc.d 服务名 defaults
删除：sudo update-rc.d -f 服务名 remove
