2 解决方案

我是方案一解决问题的。

2.1 方案一：禁用NetworkManager

1
2
3
systemctl stop NetworkManager
systemctl disable NetworkManager
reboot

2.2 方案二：修改mac地址

ip addr show查看当前mac地址

修改/etc/sysconfig/network-scripts/下以ifcfg开头的网络链接文件

添加或修改下面语句

1
HWADDR="00:50:56:3a:f9:77"

Finally 躺板板

红伞伞白杆杆，吃完一起躺板板

躺板板埋山山，亲朋都来吃饭饭

饭饭里有红伞伞，吃完全村埋山山，来年长满红伞伞
