https://github.com/stephanritscher/reboot-guard

# 下载
wget -cP /usr/sbin/ https://raw.githubusercontent.com/stephanritscher/reboot-guard/refs/heads/master/rguard# 赋予可执行权限
chmod +x /usr/sbin/rguard# 下载service文件
wget -cP /etc/systemd/system/ https://raw.githubusercontent.com/stephanritscher/reboot-guard/refs/heads/master/rguard.service# 重载服务
systemctl daemon-reload# 设置开机自启动
systemctl enable --now rguard.service

当关机保护被停止时，手动启动关机保护

# 启动关机保护
rguard -1

结果验证

关机命令	重启命令
poweroff	reboot
init 0	init 6
shutdown now	shutdown -r now
halt

systemctl关机命令	systemctl重启命令
systemctl poweroff	systemctl reboot

关机

# 停止关机保护
rguard -0# 执行关机命令
poweroff
