我正在尝试在Digital Ocean服务器上运行最简单的节点服务器。我使用port 8080
开发并测试了代码没有问题。但是,现在我想使用port 80
,以便在导航到我的服务器的IP地址时不需要指定端口(因此它将默认)。
当我将端口更改为80
并以sudo
运行应用程序时,即使我没有在服务器上运行任何其他应用程序(根本),我也会获得Error: listen EADDRINUSE
。有没有办法清除port 80
使用?
我在这里查看了How to fix Error: listen EADDRINUSE while using nodejs? 但这些建议都没有奏效。这绝对是我服务器上唯一的程序。
我的代码中没有其他进程正在侦听任何端口。实际上我的服务器上根本没有运行app,所以我不明白端口是如何使用的。谢谢你的帮助
编辑。以下是运行netstat
的内容:

答案 0 :(得分:0)
我收到了这个错误。即使地址未被使用,如果由于任何原因无法将进程附加到端口,Node似乎也会抛出此错误。
在我的情况下(数字海洋液滴)连接到端口80需要var SessionSchema = new Schema({
session: String,
expires: String
}, {collection: 'sessions'}
);
。
