重启iptables时报错：Job for iptables.service failed because the control process exited with error code. See “systemctl status iptables.service” and “journalctl -xe” for details.
于是运行提示中的"systemctl status iptables.service"查看原因：
#iptables无法启动IPv4防火墙
Faild to start IPv4 firewall with iptables
依次运行以下命令解决：
#执行下面命令前一定要备份文件iptables!!!
#执行下面命令前一定要备份文件iptables!!!
#执行下面命令前一定要备份文件iptables!!!
#依次执行如下命令
> service iptables save
> systemctl stop firewalld
> systemctl disable firewalld
> systemctl start iptables
> systemctl status iptables
> systemctl enable iptables
