Question

我在本地的ubuntu 16.04系统上安装了nginx。在我将它用于生产之前，我才开始了解nginx。

我在localhost:3000

上运行了一个rails应用程序

我想在浏览器/客户端和localhost:3000上运行的主应用程序之间建立一个代理服务器。通过回答一些问题，我尝试将默认listen 80 default_server;更改为listen 3000 default_server;。它没有用。

我正在附加我尝试过的已编辑的/etc/nginx/sites-available/default文件。请让我知道如何建立代理，以便它监听3000端口。

的/ etc / nginx的/位点可用/默认

如果我理解了这个问题，你希望nginx在端口80上侦听并将所有传入请求传递给在端口3000上运行的Rails应用程序。您可以通过将位置块更改为：

来实现

listen 80;

location / {
    proxy_pass http://127.0.0.1:3000;
}

它将获取所有请求，并将它们传递到主机nginx运行的端口3000上。

将nginx默认文件上的默认代理端口更改为其他端口
