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;
}
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.
server {
server_name .example.com;
return 301 http://www.example.com$request_uri;
}
server {
server_name www.example.com;
[...]
}
