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 Failedtostop iptables.service: Unit iptables.servicenot 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 Redirectingto /bin/systemctl stop iptables.service //检查防火墙状态 service iptables status Redirectingto /bin/systemctl status iptables.service 鈼iptables.service- IPv4 firewallwith iptables Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled) Active: inactive (dead)
