由于某种原因，我的 apache2 停止工作了。我尝试卸载它，但问题仍然存在。以下是我尝试过的一些命令及其结果，希望对您有所帮助：
sudo systemctl status apache2：

答案1
你不能让两个 HTTP 服务器在同一台机器上监听同一个端口（除非你把它们放在不同的接口上，或者你使用桥接网络连接）看起来nginx服务器正在您的系统中运行，因此如果您想使用 Apache2，您可以停止nginx服务 ：
sudo service nginx stop
如果你想阻止nginx在启动时自动启动（这可能会阻止 apache2 启动，反之亦然），你可以通过以下方式禁用其服务系统控制：
sudo systemctl disable nginx
