nginx rewrite all wildcard subdomains to www.site.com

nginx, url-rewriting

Solution

The best way to do this in nginx is with a combination of two server blocks:

server {
  server_name *.example.org;
  return 301 $scheme://example.org$request_uri;
}

server {
  server_name www.example.org;

  #add in further directives to serve your content
}

I have tested this on my laptop, since you reported it not working. I get the following result locally (after adding `www2.test.localhost` and `www.test.localhost` to my `/etc/hosts`, along with the nginx config bit, and reloading nginx):

$ curl --head www2.test.localhost
HTTP/1.1 301 Moved Permanently
Server: nginx/1.2.6
Date: Thu, 07 Mar 2013 12:29:32 GMT
Content-Type: text/html
Content-Length: 184
Connection: keep-alive
Location: http://www.test.localhost/

So yes, this definitely works.

Problem

Using nginx, I want to redirect all subdomains of `example.com` to `www.example.com`. I have seen redirects here to redirect non-www to www or vise versa, but I also want `www2.site.com blabla.site.com` to be redirected. I have a wildcard dns for the domain. For apache this can be done easily with following: ``` RewriteCond %{HTTP_HOST} !www.example.com [NC] RewriteRule (.*) http://www.example.com%{REQUEST_URI} [R=301,L] ``` The below seem to work, but it is not recommended according to the ifisevil page. ``` if ($http_host !~ "www.site.com"){ rewrite ^(.*)$ http://www.example.com$request_uri redirect; } ```
