Mapping subdomains to URLs with nginx

Question

I\'m very new to nginx, so forgive me if my explanations are off. I\'ll do my best to explain what I am trying to achieve.

Using WordPress and nginx, I would like us

Answer 1

the following should do it:

server {
  listen 80; listen 443;
  server_name *.example.com;

  if ($host ~ "^(.*)\.example\.com$" ) { set $subdomain $1;}
  rewrite ^ $scheme://example.com/$subdomain/$request_uri permanent;
}

(as an aside: the regex ^ matches all url's the most efficiently, and the standard nginx variable $request_uri holds the uri including arguments so you don't need the (.*) group in the rewrite)

additionally add a second serverblock for the domains you don't want redirected:

server {
  listen 80; listen 443;
  server_name cdn.example.com admin.example.com;
  # do whatever with the requests of the reserved subdomains;
}
