Mirror site in Tor?

Question

Tor

Good day!

I already have an example.com site that works on the web, I want to be able to access my site in Tor through the .onion domain as well. So far I have been able to install Tor on a server, but when I open the .onion domain, instead of my site (example.com), an nginx welcome page is shown.

I want the .onion domain to show the content of example.com, without redirects.
I tried to change the default nginx configuration and set the site directory from example.com as the root directory, but this only led to a redirect from .onion to example.com.

Please tell me how this can be done? The server is running Ubuntu OS, Nginx.
