Nginx node setup to custom directory

Question

I am using nginx first time so need help.

My app is running in /root/project1/tools (this directory is having server.js)

How i can connect nginx to this directory. I searched lot and do not find direct ans. Think nginx will find my server.js by port number not by path. is that true?

I am using linux ubuntu 18

More over nginx is throwing error

                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

And my node app is running on port 8080. Any idea what can i do to setup nginx. any reference to resource will be helpful.

Answer 1

All you have to do is setup a Reverse Proxy Server in Nginx

Start your NodeJS Server on whatever port

node server.js

If you are using any process management tool like pm2 then

pm2 server.js

Now in nginx config what you have to do is proxying all request to local nodejs server so

upstream app_yourdomain {
  server 127.0.0.1:8080;
  keepalive 8;
}



# the nginx server instance
server {
  listen 80;
  listen [::]:80;
  server_name nativeiconbase.com www.nativeiconbase.com;
  access_log /var/log/nginx/nativeiconbase.com.log;

  # pass the request to the node.js server with the correct headers
  # and much more can be added, see nginx config options
  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://localhost:8080;
    proxy_redirect off;
  }
}

I have just changed the line proxy_pass http://localhost:8080 in your code
