nginx, www to non-ww, tried a dozen solutions

Question

I have an small VPS hosting one wordpress website. I use ngingx 1.4.4 on Debian 12.04. I follow some tutorials i found online and here is what i managed to make. Here is my server block:

server {
listen  80;
#listen   [::]:80 default ipv6only=on; ## listen for ipv6

location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
expires 365d;

}

root /var/www;
index index.php index.html index.htm;
server_name bloggeri.es;

rewrite ^/sitemap_index\.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?\.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;  

# unless the request is for a valid file, send to bootstrap
if (!-e $request_filename)
{
    rewrite ^(.+)$ /index.php?q=$1 last;
}

# Make site accessible from http://localhost/
location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to index.html
    try_files $uri $uri/ /index.html;
    # Uncomment to enable naxsi on this location
    # include /etc/nginx/naxsi.rules
}

location /doc/ {
    alias /usr/share/doc/;
    autoindex on;
    allow 127.0.0.1;
    deny all;
}

# Only for nginx-naxsi : process denied requests
#location /RequestDenied {
    # For example, return an error code
    #return 418;
#}

error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
    root /usr/share/nginx/www;
}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {

    # With php5-cgi alone:

}

# Use gzip compression

}

Any one has a solutions? I don`t know even if this is a good configuration

Answer 1

The trick is to make a server block that matches the www url's and redirect them to a non-www url, add this above your server block after replacing example.com with your actual domain.

server {
  server_name www.example.com;
  return 301 $scheme://example.com$request_uri$is_args$query_string;
}
server {
  server_name example.com;
  # your actual config goes here
}
