nginx rewrite specific sub domains

  • 772

I am trying to rerwrite any sub domains outside of an approved list i.e. (dev,test,home).domain.com

here is what I am working with now:

#rewrite all sub domains
 if ($host ~* "^([^.]+(\.[^.]+)*)\.domain.com$"){
        rewrite ^(.*)$ http://domain.com$1 permanent;
        break;
    }

the problem is it rewrites all sub domains. I have a solution in apache but I am having issues converting it. apache version:

RewriteCond %{HTTP_HOST} !^(dev|test|local\.blog)\.domain\.me$ [NC]

Updates:

server {
    listen 80;
  server_name *.domain.com domain.com;
  root /srv/www/www.domain.com;
  access_log /srv/logs/www_domain.com.access;
  error_log /srv/logs/www_domain.com.error error;

  error_page 400 401 402 403 404 500 502 503 504 /error.htm;
  location  /error.htm {
    internal;
  }
  # ------------------------------------------------------------------------  
  # remove all sub domains and www

apache-2.2 rewrite nginx wordpress

4 Answers

  1. Check nginx documentation how to convert apache rewrite rules to nginx.

    server {
  listen 80;
  server_name domain.com ~(dev|test|local)\.domain\.com$;

  # ... your rules here ... 

}

server {
  listen 80 default_server;
  server_name *.domain.com;
  rewrite ^ http://domain.com$request_uri? permanent;
}

    based on @AlexD reply I have updated my solution. if you have any other suggestions fellow geeks, let me know.

    server {
  listen 80;
  server_name *.noconformity.co;
  rewrite ^ http://noconformity.co$request_uri? permanent;

  3. Looks like you must use negative look-behind:

    server {
    listen 80;
    server_name *.domain.com;
    ...

    if ($host ~* (?<!(dev|test|local))\.domain\.com) {
        rewrite ^ http://domain.com$request_uri permanent;
    }

}

  4. after locating a killer tool : http://www.anilcetin.com/convert-apache-htaccess-to-nginx/ I was able to rebuild my nginx vhost config to work correctly, however, I am open to suggestions , modifications. This is a multi host server, and individual host file in sites-available for each host

    server {
  listen 80;
