## 查看系统是否安装firewalld和firewall-config ##

rpm -qa|grep firewalld;rpm -qa|grep firewall-config
    输出以下类似信息代表已经安装
    firewalld-filesystem-0.5.3-5.el7.noarch
    firewalld-0.5.3-5.el7.noarch
    firewall-config-0.5.3-5.el7.noarch

如果没有则安装

## 安装firewalld ##

yum install firewalld firewall-config -y
    sudo systemctl start firewalld  # 开启防火墙
    sudo systemctl enable firewalld  # 开机启动防火墙

## 开启端口 ##

firewall-cmd --zone=public --add-port=22/tcp --permanent
    firewall-cmd --zone=public --add-port=80/tcp --permanent
    firewall-cmd --zone=public --add-port=8080/tcp --permanent
    firewall-cmd --zone=public --add-port=3306/tcp --permanent
    firewall-cmd --zone=public --add-port=6349/tcp --permanent
    firewall-cmd --reload
    
    firewall-cmd --zone=public --list-ports  # 查看当前系统打开的所有端口

## 关闭端口（如果需要） ##

firewall-cmd --zone=public --remove-port=22/tcp --permanent
    firewall-cmd --reload
