防火墙操作
安装Firewall命令:
yum install firewalld firewalld-config
Firewall开启常见端口命令:
firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --permanent --zone=public --add-port=443/tcp
firewall-cmd --permanent --zone=public --add-port=22/tcp
firewall-cmd --permanent --zone=public --add-port=21/tcp
firewall-cmd --permanent --zone=public --add-port=53/udp
Firewall关闭常见端口命令:
firewall-cmd --zone=public--remove-port=80/tcp --permanent
firewall-cmd --zone=public--remove-port=443/tcp --permanent
firewall-cmd --zone=public--remove-port=22/tcp --permanent
firewall-cmd --zone=public--remove-port=21/tcp --permanent
firewall-cmd --zone=public--remove-port=53/udp --permanent
批量添加区间端口
firewall-cmd --permanent --zone=public --add-port=4400-4600/udp
firewall-cmd --permanent --zone=public --add-port=9600-9610/tcp
开启防火墙命令:
systemctl start firewalld.service
重启防火墙命令:

查看端口列表:
firewall-cmd --permanent --list-port
