我想在 Digital Ocean 下的 ubuntu 18 上为我的托管设置 https,如下所示: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04

但我在 ufw 设置方面遇到了问题:

# sudo ufw status
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw allow 'Apache'
Rules updated
Rules updated (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo systemctl reload apache2
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw allow 'Apache Full'
Skipping adding existing rule
Skipping adding existing rule (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw delete allow 'Apache'
Rules updated
Rules updated (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive

我看到状态是不活跃的。

我试着做:

sudo ufw 应用列表

Available applications:
Apache
Apache Full
Apache Secure
OpenSSH
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw allow 'Apache'
Rules updated
Rules updated (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive

我认为这个错误很严重,没有继续执行下一个命令。为什么会出错以及如何解决?

修改 block #2:我做到了:

# ufw allow 80
Rules updated
Rules updated (v6)
root@nsn-do-lamp:~# sudo ufw app list
Available applications:
Apache
Apache Full
Apache Secure
OpenSSH
root@nsn-do-lamp:~# sudo ufw status
Status: inactive
root@nsn-do-lamp:~# sudo service apache2 restart
root@nsn-do-lamp:~# sudo ufw status
Status: inactive

我也重新启动了操作系统,但状态无论如何都是不活动的。怎么了?同样使用端口 443。我检查我的端口:

谢谢!

最佳答案

你可以尝试用命令开启ufw

  sudo ufw enable
