CentOS6关闭防火墙使用以下命令,

//临时关闭

service iptables stop

//禁止开机启动

chkconfig iptables off

CentOS7中若使用同样的命令会报错,

stop  iptables.service

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

这是因为CentOS7版本后防火墙默认使用firewalld,因此在CentOS7中关闭防火墙使用以下命令,

//临时关闭

systemctl stop firewalld

//禁止开机启动

systemctl disable firewalld

Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

当然,如果安装了iptables-service,也可以使用下面的命令,

yum install -y iptables-services

//关闭防火墙

service iptables stop

Redirecting to /bin/systemctl stop  iptables.service

//检查防火墙状态

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)

成长就是不断打破并重建三观
