Question

方案是我已经在aws上创建了一个实例，并且在我的rails上创建了一个实例，并在localhost：3000上使用rails s命令运行。并且服务器正在使用PUMA运行。

现在我想看到我的应用在公共DNS上运行http://ec2-13-56-156-255.us-west-1.compute.amazonaws.com/

为此我已经安装了nginx web服务器，我能够看到nginx的默认索引页面，但是当我在nginx.conf文件中进行更改以查看我的应用程序时，它给出了403错误。变化如下。

文件路径：/etc/nginx/nginx.conf

user ec2-user;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {
 worker_connections 1024;
}

http {
  log_format  main  '$remote_addr - $remote_user [$time_local] 
 "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile            on;
tcp_nopush          on;
tcp_nodelay         on;
keepalive_timeout   65;
types_hash_max_size 2048;

include             /etc/nginx/mime.types;
default_type        application/octet-stream;


include /etc/nginx/conf.d/*.conf;
index   index.html index.htm;

upstream app {
 server 127.0.0.1:3000;
 #server unix:///path_to_my_app/tmp/sockets/puma.sock fail_timeout=0;
}

server {
    listen       80 default_server;
    listen       [::]:80 default_server;
    server_name  13.56.156.255;
    root        /home/ec2-user/Projects/aqua_web_v1.0;
    #root         /usr/share/nginx/html;

   #location / {
   #}

   location @app {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect off;        
      proxy_pass http://app;
    }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }

您需要通过复制默认文件来创建服务器块配置文件：

sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/example.com

现在用sudo previlege

打开该文件

sudo nano /etc/nginx/sites-available/example.com

然后将您的主机名添加到：

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/example.com;
        index index.html index.htm index.nginx-debian.html;

        server_name example.com www.example.com;

        location / {
                try_files $uri $uri/ =404;
        }
}
