我是新手，你能帮帮我吗

Answer 1

我也面临同样的问题。

首先检查

$ sudo systemctl status nginx

如果nginx处于活动状态，则停止此操作

$ sudo systemctl stop nginx

然后再次尝试在不同的终端启动 apache2 服务器。

Answer 2

首先删除apache2

sudo apt-get --purge remove apache2 sudo apt-get autoremove

之后，如果有文件（.conf）/etc/sites-available使用删除它们

rm example.com.conf

然后再次安装 sudo apt-get install apache2

现在它会修复现在检查它 sudo ufw allow 'Apache' sudo systemctl status apache2
