通过停止和重新启动网络服务解决Linux网络配置错误，包括`systemctl stop NetworkManager`，`systemctl disable NetworkManager`，然后启动网络服务`systemctl start network.service`，最终成功恢复网络连接。

在一个博客上找到了我需要的答案，就是简单的关闭网络服务，然后再加载服务，然后再重启就好了，

[root@CT71 ~]# systemctl status network.service 
● network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)

Aug 04 08:20:31 CT71 systemd[1]: Failed to start LSB: Bring up/down networking.

如下：
1、

systemctl stop NetworkManager

2、

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.

然后重启网络：

systemctl start network.service

可以使用了：
