1）cp /lib/systemd/system/rc-local.service /etc/systemd/system
2）修改/etc/systemd/system/rc-local.service，在该文件的最底部添加（可用vi /etc/systemd/system/rc-local.service命令）
[Install]
WantedBy=multi-user.target
Alias=rc-local.service
3）创建/etc/rc.lcoal文件（vi /etc/rc.lcoal）
#!/bin/sh
/usr/local/sbin/rtlfxled&
source /etc/profile 特别注意，java程序必须加，要不然报错
/hw/start.sh &
exit 0
4）执行 chmod -R 777 /etc/rc.local
5）执行systemctl start rc-local.service
systemctl enable test.service
