Linxu中使用防火墙命令（sudo命令执行）

sudo : 暂时切换到超级用户模式以执行超级用户权限，一般指的是root用户，提示输入密码时该密码为当前用户的密码，而不是超级账户的密码。不过有时间限制，Ubuntu默认为一次时长15分钟。

查看所有开启端口，查看防火墙，添加的端口也可以看到
firewall-cmd --list-all
重启防火墙服务
sudo systemctl restart firewalld.service
sudo systemctl enable firewalld
查看防火墙状态
sudo systemctl status firewalld
永久关闭防火墙
sudo systemctl disable firewalld
查看防火墙状态
sudo systemctl stop firewalld
