如何配置 nginx 以代理到 rails 应用程序？这样我就不用说 domain.com:port

Question

更新： 目前我在 domain.com:3000 访问我的应用程序，但我想访问 domain.com 以查看我的应用程序
我在 80 设置了 nginx 以在 3000 代理我的 rails 应用程序。下面是配置

upstream railsapp {
  server 127.0.0.1:3000;
}

server {
  listen 80;
  server_name APP;

  # Tell Nginx and Passenger where your app's 'public' directory is
  root /var/www/APP/current/public;
  index index.html index.htm;

  # Static assets are served from the mentioned root directory
location / {
    root /var/www/APP/current;
    index index.html index.htm;

    proxy_pass http://railsapp/;
    proxy_redirect off;
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    # proxy_set_header X-Real-Port $server_port;
    # proxy_set_header X-Real-Scheme $scheme;
    proxy_set_header X-NginX-Proxy true;
}

  # Turn on Passenger
  passenger_enabled on;
  passenger_ruby /usr/local/rvm/gems/ruby-2.1.3/wrappers/ruby;
}

我指的是：

它位于 /etc/nginx/sites-enabled/APP.conf 并包含在 /etc/nginx/nginx.conf 中，如下所示 http{...}

include /etc/nginx/sites-enabled/*;

但我的 APP.com 仍然显示 'Welcome to nginx on Ubuntu!' 并且 APP.com:3000 显示我的应用程序。我做错了什么？

我正在使用什么：
Ubuntu 14.04 ec2 实例
nginx 1.8.0
独角兽服务器 3000

您只需添加一个新的服务器{}块并添加passenger_root。这就是我所做的。然后在配置之后，在你的浏览器上尝试 server_name:port "APP.com:3000"

upstream railsapp {
  server 127.0.0.1:3000;
}

// add new server block here... modify with below example.
server {
    listen *:3000;
    server_name  APP.com;
    rack_env development;
    root /directory/to/rails-app/public;
    index  index.html index.htm index.html.erb;
    passenger_enabled on;
}

server {
  listen 80;
  server_name APP;

  # Tell Nginx and Passenger where your app's 'public' directory is
  root /var/www/APP/current/public;
  index index.html index.htm;

  # Static assets are served from the mentioned root directory
location / {
    root /var/www/APP/current;
    index index.html index.htm;

    proxy_pass http://railsapp/;
    proxy_redirect off;
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    # proxy_set_header X-Real-Port $server_port;
    # proxy_set_header X-Real-Scheme $scheme;
    proxy_set_header X-NginX-Proxy true;
}

  # Turn on Passenger
  passenger_enabled on;
  //add passenger_root
  passenger_root /directory/to/phusion_passenger/locations.ini;
  passenger_ruby /usr/local/rvm/gems/ruby-2.1.3/wrappers/ruby;
}

我正在尝试运行独角兽，这样我就可以将我的应用分叉到多个实例。我想这里的问题是，我设置了 passenger_enabled 并且实际上是运行ning unicorn on 3000.

所以我运行乘客

passenger start -a 127.0.0.1 -p 3000 -d -e production

我的 nginx conf 是这样的，

server {
listen 80;
server_name www.APPNAME.com;

# Tell Nginx and Passenger where your app's 'public' directory is
root /var/www/APPNAME/current/public;
index index.html index.htm;

# Static assets are served from the mentioned root directory
location / {
#  root /var/www/APPNAME/current;
#  index index.html index.htm;
proxy_pass http://127.0.0.1:3000;

proxy_redirect off;
proxy_set_header X-Real-IP  $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
# proxy_set_header X-Real-Port $server_port;
# proxy_set_header X-Real-Scheme $scheme;
proxy_set_header X-NginX-Proxy true;
}

# Turn on Passenger
passenger_enabled on;
passenger_ruby /usr/local/rvm/gems/ruby-2.1.3/wrappers/ruby;
}

现在一切正常！
