百度答案：

mac地址不对，修改mac地址。

也许有人确实是mac问题，但是莫名其妙怎么可能mac地址更改了，除非你添加新网卡或者克隆的虚拟机。

我特么真笑了，天下百度文章一大抄啊。。。。。。。。

没办法了，Google一下吧，偶然看到一个文章，大意是跟系统自带的NetworkManager这个管理套件有关系，关掉就可以解决。

试一下：

systemctl stop NetworkManager

systemctl disable NetworkManager

[root@localhost ~]# systemctl stop NetworkManager
[root@localhost ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

网络正常启动，访问正常。
