Proxy NodeJS app to Nginx Proxy

proxy.md

###After Install Nginx

After Install Nginx need to configure the files to add proxy to nginx

cd /etc/nginx/sites-available/
vim test

In the file you need to paste the next code.

# Node App Staging on Port 3000
upstream example{
    server 127.0.0.1:3000;
}

# NGINX Server Instance
server {
    listen 0.0.0.0:80;
    server_name example.com;
    access_log /var/log/nginx/example.com.log;

    # Gzip Compression
    gzip on;
    gzip_comp_level 6;
    gzip_vary on;
    gzip_min_length  1000;
    gzip_proxied any;
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_buffers 16 8k;

    # Proxy to the Node instance
    location / {
      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-NginX-Proxy true;
      proxy_pass http://example.com;
      proxy_redirect off;
    }
 }

Save the file and make a symbolic link to activate the new configuration.

ln -s /etc/nginx/sites-available/test /etc/nginx/sites-enabled/test
/etc/init.d/nginx reload

If you don't have a DNS server need to modify the hosts file.

sudo vim /etc/hosts

and adds the next line

127.0.0.1    example.com

Now you can open in your browser http://example.com/ and now you can see your app using the name that you select it.
