centos7用命令關閉防火牆

今天要安裝Navicat，先關閉centos的防火牆，但是報錯了。。
service iptables stop
Redirecting to /bin/systemctl stop iptables.service
Failed to stop iptables.service: Unit iptables.service not loaded.

#service iptables status
Redirecting to /bin/systemctl status iptables.service
iptables.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)
後來知道原來centos7的防火牆不是這樣關的。

參考Redhat Linux 7 命令關閉防火牆

使用systemctl即可解決

systemctl stop firewalld # 關閉防火牆

systemctl status firewalld # 查看防火牆狀態

systemctl disable firewalld # 永久關閉防火牆，重啓後，防火牆不會自動啓動

systemctl enable firewalld # 開啓防火牆
