CentOS6關閉防火牆使用以下命令,
開啟防火牆
systemctl start firewalld
//臨時關閉
# service iptables stop
//禁止開機啟動
# chkconfig iptables off
CentOS7中若使用同樣的命令會報錯,
# stop iptables.service
Failed to stop iptables.service: Unit iptables.service not loaded.
這是因為CentOS7版本后防火牆默認使用firewalld,因此在CentOS7中關閉防火牆使用以下命令,
//臨時關閉
# systemctl stop firewalld
//禁止開機啟動
# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
當然,如果安裝了iptables-service,也可以使用下面的命令,
# 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
