I know that it is possible to set some websites on different Ports, but i want this.
I read stuff about docker & ngix reverse proxy. Could someone link give me a good explanation.

If you are trying to host 4 different domains on the same server, then
first install NGINX with these commands:
sudo apt update
sudo apt install nginx
Then,
create 4 different domain.conf files in the /etc/nginx/sites-enabled directory. ( here domain can be anything that you can remember to map the sites ).
paste the below code with some modifications:
server{
listen 80 default_server;
listen [::]:80 default_server;
server_name **domain**;
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_redirect off;
proxy_pass http://127.0.0.1:**port**/;
proxy_redirect off;
}
}
In the above code, change the domain and port accordingly.
run sudo nginx -t and check if there's any issue raised.
restart the nginx server ( sudo service nginx restart )
Now it should be running on 4 different servers with HTTP
For HTTPS
Install certbot
apt-get update
sudo apt-get install certbot
apt-get install python-certbot-nginx ( try apt-get install python-certbot-nginx for Ubuntu 18.04 and later )
Run the following command to generate certificates with the nginx:
sudo certbot --nginx -d domain.com -d www.domain.com
Now if you look at the domain.conf files of /etc/nginx/sites-enabled , you notice the certbot added few lines.
Now restart the nginx server and boom!!!! it works.
Note : you have to purchase those domains with the domain providers.
Hope this helps you!!!
Infact I stucked very much to keep this docs with me previously...
comment if you get any errors or doubts.
