3.排查方向1
第一步：查看NetworkManager服务状态：
systemctl status NetworkManager
第二步：关闭NetworkManager，并设置开启默认不启动该服务：
systemctl stop NetworkManager;
systemctl disable NetworkManager
第三步：重启网络服务
systemctl restart network.service
systemctl status network.service
以上操作若无法解决该问题
第四步：注释文件/etc/sysconfig/network-scripts/ifcfg-配置_1文件 中的UUID以及HWADDR两列
清空/etc/udev/rules.d/70-persistent-net.rules记录
重启reboot
