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
