# service iptables save The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
出錯資訊如上所示
解決方案:
首先停止防火牆
systemctl stop firewalld
systemctl mask firewalld
然後安裝iptables-services
yum install iptables-services
設定開機啟動防火牆
systemctl enable iptables
可以使用下面命令管理iptables
systemctl [stop|start|restart] iptables
這時可以儲存防火牆規則了
service iptables save
or
/usr/libexec/iptables/iptables.init save
如果你之後要使用firewall的話：
執行命令，即可實現取消服務的鎖定
# systemctl unmask firewalld
下次需要鎖定該服務時執行
# systemctl mask firewalld
