CentOS7中若使用一樣的命令會報錯,spa

stop iptables.service Failed to stop iptables.service: Unit iptables.service not loaded.

這是由於CentOS7版本後防火牆默認使用firewalld,所以在CentOS7中關閉防火牆使用如下命令,code

//臨時關閉
systemctl stop firewalld
//禁止開機啓動
systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

固然,若是安裝了iptables-service,也可使用下面的命令,ip

yum install -y iptables-services //關閉防火牆 service iptables stop Redirecting to /bin/systemctl stop iptables.service //檢查防火牆狀態 service iptables status Redirecting to /bin/systemctl status iptables.service 鈼iptables.service - IPv4 firewall with iptables Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled) Active: inactive (dead)
