网上的一些办法，比如停止NetworkManager，没有什么用。欢迎关注微信公众号九万里大数据。

解决办法

先确保ifcfg-eth0配置文件信息准备无误

vi /etc/sysconfig/network-scripts/ifcfg-eth0

移除/etc/sysconfig/network-scripts 目录下的除了ifcfg-eth0和ifcfg-lo这两个之外的其他网卡配置，比如删除ifcfg-enp0s3

如果再次运行systemctl restart network依然报错Failed to start LSB: Bring up/down networking。则重启一下机器reboot即可（关键）。重启后，恢复正常，再次运行systemctl restart network也没有报错了。欢迎关注微信公众号九万里大数据。
