WantedBymulti-user.target创建 /etc/rc.local
Ubuntu 20.04 默认不存在 /etc/rc.local需要自己创建注意第一行必须是#!/bin/bash否则启动rc-local服务报错。Failed at step EXEC spawning /etc/rc.d/init.d/nginx: Exec format error.
cat /etc/rc.local
#!/bin/bash
/usr/sbin/ifconfig enp0s1 down
/usr/sbin/ifconfig enp0s1 hw ether b6:f5:2c:0d:3d:16
/usr/sbin/ifconfig enp0s1 up修改 /etc/rc.local 权限
chmod 755 /etc/rc.local安装ifconfig命令
apt-get install net-tools设置rc-local为开机自启动
systemctl enable rc-local启动rc-local服务
启动rc-local服务后mac地址即可更改。并且以后reboot机器也不会失效。
systemctl start rc-local
