Question

我有一个有5个可用IP地址的专用服务器，下面说X.X.X.1 - X.X.X.5是我的IP地址默认架构

X.X.X.1 - ns1.ex.com - 使用BIND

命名服务器

X.X.X.2 - ns2.ex.com

X.X.X.3 - www.ex.com - 使用nginx作为网络服务器

X.X.X.4 - 没什么

X.X.X.5 - 没什么

现在我正在尝试在nodejs(127.0.0.1:4501)上进行反向代理....我已经启动了应用程序，当我尝试通过反向代理访问节点应用程序时，它无法正常工作。我甚至试图调用http://localhost:4501/和http://localhost:4501/test/之类的curl，因为app.js出现在/var/www/test/app.js。我也尝试将app ip地址更改为X.X.X.3，但没有结果

当我没有设置节点应用程序的IP地址时，它正在处理我放入的任何端口。我想将IP地址设置为localhost，以便只能通过Nginx访问它并且我有我的数据库我也想躲在Nginx身后。

以下是我的conf文件：

nginx.conf:出现在/usr/local/nginx/conf/nginx.conf

这是一个非常愚蠢的错误，我的身边指出@Ben Fortune express listen方法首先接收端口然后ip地址

Nginx反向代理不在localhost上使用Nodejs
