Nginx Remove WWW And Respond To Both

Question

I have the following nginx configuration fragment:

server {
   listen 80;

   server_name mydomain.io;

   root /srv/www/domains/mydomain.io;

   index index.html index.php;

   access_log /var/log/nginx/domains/mydomain.io/access.log;
   error_log /var/log/nginx/domains/mydomain.io/error.log;

   location ~\.php {
      try_files $uri =404;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_intercept_errors on;
      fastcgi_pass 127.0.0.1:9000;
      include /etc/nginx/fastcgi_params;
   }
}

First, how can I make the server block respond to both http://www.mydomain.io and also http://mydomain.io. Second, I want to force if they come from http://www.mydomain.io to redirect to http://mydomain.io.

Thanks.

Answer 1

On the first question - simply add both domains:

server_name mydomain.io www.mydomain.io;

For the second, you'll need this simple redirect:

server {
      listen 80;

      server_name www.mydomain.io mydomain.io;

      if ($host = 'www.mydomain.io' ) {
         rewrite  ^/(.*)$  http://mydomain.io/$1  permanent;
      }
