无法在防火墙中允许Nginx

Question

我使用以下命令在Ubuntu18.04服务器上安装了Nginx：

$ sudo apt-add-repository ppa:hda-me/nginx-stable

$ sudo apt update

$ ubuntu@www-example-com:~$ sudo apt install brotli nginx nginx-module-brotli

The Brotli dynamic module for nginx has been installed.
To enable this module, add the following to /etc/nginx/nginx.conf
and reload nginx:
    # ngx_brotli filter module - used to compress responses on-the-fly.
    load_module modules/ngx_http_brotli_filter_module.so;
    # ngx_brotli static module - used to serve pre-compressed files.
    # Both modules could be used separately
    load_module modules/ngx_http_brotli_static_module.so;

Please refer to the module documentation for further details:
https://github.com/google/ngx_brotli

我的问题是，使用以下命令向防火墙添加Nginx是不可能的。我不明白为什么它不起作用

$ ubuntu@www-example-com:~$ sudo ufw allow 'Nginx Full'
ERROR: Could not find a profile matching 'Nginx Full'

$ ubuntu@www-example-com:~$ sudo ufw app list

  OpenSSH

Answer 1

sudo ufw app list的输出显示没有创建nginx配置文件。

在ubuntu堆栈交换上的这个职位对如何创建应用程序配置文件有一个很好的总结，或者您可以使用@Diego Velez建议的更简单的解决方案(这就是我要做的)。
