ERROR: Failed to load ‘/etc/sysconfig/network-scripts/ifcfg-eth0‘: [Errno 13] 权限不够: ‘/etc/sysconfig/

报错如图所示：

本机是有4个网卡的文件，因此执行：

restorecon -R /etc/sysconfig/network-scripts/ifcfg-eth0

restorecon -R /etc/sysconfig/network-scripts/ifcfg-eth1

restorecon -R /etc/sysconfig/network-scripts/ifcfg-eth2

restorecon -R /etc/sysconfig/network-scripts/ifcfg-eth3

systemctl restart firewalld.service  

最后重启防火墙，状态恢复正常。
