nginx 无法在 Ubuntu 15.10 服务器上安装

Question

我正在尝试在我新安装的带有 Mate 桌面的 Ubuntu Server 15.10 上安装 nginx。

我做了一个快速更新：

sudo apt-get update

现在尝试安装nginx：

sudo apt-get install nginx

这是我得到的：

server@Node1:~/nod$ sudo apt-get install nginx

这是输出 systemctl status nginx.service

这是我第一次使用 15.10，希望能更轻松。我几乎没有时间花在服务器安装和考虑回滚到 14.xx 上。如果您有任何解决方案，请告知。

谢谢你。

在您的情况下，端口 80 或端口 98 已被其他进程使用。您需要找出哪个进程正在使用这些端口并终止该进程或服务。

sudo netstat -nlp

然后你可以尝试启动nginx。顺便说一句，您的案例中已经安装了 nginx。
