    centOS7 查看防火墙状态
    一、防火墙的开启、关闭、禁用命令

    (1)设置开机启用防火墙:systemctl enable firewalld.service

    (2)设置开机禁用防火墙:systemctl disable firewalld.service

    (3)启动防火墙:systemctl start firewalld

    (4)关闭防火墙:systemctl stop firewalld

    (5)检查防火墙状态:systemctl status firewalld

    二、使用firewall-cmd配置端口

    (1)查看防火墙状态:firewall-cmd --state

    (2)重新加载配置:firewall-cmd --reload

    (3)查看开放的端口:firewall-cmd --list-ports

    (4)开启防火墙端口:firewall-cmd --zone=public --add-port=9200/tcp --permanent

    命令含义:

    –zone #作用域

    –add-port=9200/tcp #添加端口,格式为:端口/通讯协议

    –permanent #永久生效,没有此参数重启后失效

    注意:添加端口后,必须用命令firewall-cmd --reload重新加载一遍才会生效

    (5)关闭防火墙端口:firewall-cmd --zone=public --remove-port=9200/tcp --permanent
