Debian/Ubuntu添加rc.local文件并设置开机启动

哎呀，折腾死我了，有幸看到这篇帖子，我就转载一下吧。

比较新的Linux发行版已经没有rc.local文件了。因为已经将其服务化了。但是WiKi只给了rc.local的说明，自己尝试了systemctl又不成功。 参考：https://www.linuxidc.com/Linux/2019-09/160737.htm

# 配置service文件
sudo nano /etc/systemd/system/rc-local.service

[Unit]
 Description=/etc/rc.local Compatibility
 ConditionPathExists=/etc/rc.local

[Service]
 Type=forking
 ExecStart=/etc/rc.local start
 TimeoutSec=0
 StandardOutput=tty
 RemainAfterExit=yes
 SysVStartPriority=99

[Install]
 WantedBy=multi-user.target

# 激活rc-local.service
sudo systemctl enable rc-local.service

# 添加启动服务

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# exit 0 前面添加需要开机启动的命令
/home/pi/shutdown.py
exit 0

# 赋予执行权限
sudo chmod +x /etc/rc.local

• 重启测试
