nginx 在全新安装后无法启动

我刚刚从 digitalocean 购买了一个新的 droplet，并且安装了 nginx 并sudo apt install nginx 尝试查看它是否运行，但它出现了以下错误：

这是我的防火墙设置：

你们中有人清楚问题是什么吗？谢谢您的宝贵时间

sudo netstat -tlpn | grep :80

得到以下结果：

root@school:~# sudo netstat -tlpn | grep :80
tcp6       0      0 :::80                   :::*                    LISTEN      16792/apache2

答案1

结果sudo netstat -tlpn | grep :80表明你正在运行 Apache。两个进程不能同时监听同一个套接字，所以这就是 nginx 无法启动的原因。

您可以使用 停止 Apache sudo systemctl stop apache2，如果需要，也可以使用 禁用它sudo systemctl disable apache2。后一个命令将永久禁用 Apache 的自动启动。

如果要删除 Apache，请运行sudo apt remove apache2 apache2-data apache2-utils。
