Hosting subdomain with digital ocean and bluehost

Question

My domain is on bluehost but my backend is on digital ocean. I need to assign admin.mydomain.com to 12.12.122.1:3000 lets say.

what should I do and is there any other way ?

Answer 1

Add the domain to your Digital Ocean account first then install nginx on your server.

And use nginx to forward your requests to node:

server {
    listen 80;

    server_name example.com;

    location / {
        proxy_pass 12.12.122.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}
