某宝上买了一个小oled屏用来在树莓派上显示一些简短信息，需要开机启动，但很久才会设置一次，记下备查：

1、写个开机启动脚本，放在/etc/init.d/下，比如：/etc/init.d/minioled

 

#!/bin/bash
# /etc/init.d/minioled

### BEGIN INIT INFO
# Provides: laonan
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: minioled initscript
# Description: This service is used to manage a minioled
### END INIT INFO

case "$1" in
    start)
        echo "Starting mini OLED"
        python /home/pi/script/minioled.py &
        ;;
    stop)
        echo "Stopping mini OLED"
        #killall minioled.py
        kill $(ps aux | grep -m 1 'python /home/pi/script/minioled.py' | awk '{ print $2 }')
        ;;
    *)
        echo "Usage: service minioled start|stop"
        exit 1
        ;;
esac
exit 0

2、设置开机启动

chmod +x /etc/init.d/minioled

3、然后

sudo service minioled start # 启动
sudo service minioled stop # 停止
sudo update-rc.d minioled defaults # 设置开机启动

或

sudo systemctl start minioled # 启动
sudo systemctl stop minioled # 停止
sudo systemctl restart minioled # 重启
sudo systemctl enable minioled # 设置开机启动

我更习惯用Systemd工具
