117笔记问答在Debian系统中，Nginx通常与UFW（Uncomplicated Firewall）一起使用来配置防火墙规则。以下是如何在Debian中配置Nginx的防火墙规则的步骤：
1. 安装UFW
首先，确保你已经安装了UFW。如果没有安装，可以使用以下命令进行安装：
sudo apt update sudo apt install ufw
2. 启用UFW
安装完成后，启用UFW：
sudo ufw enable
系统会提示你确认是否启用UFW，输入y并按回车键。
3. 允许HTTP和HTTPS流量
默认情况下，UFW允许HTTP（端口80）和HTTPS（端口443）流量。你可以使用以下命令来确认这些规则是否已经存在：
sudo ufw status numbered
你应该会看到类似以下的输出：
