Redirect www to naked domain in nginx

Redirecting a www based domain to a non-www based or naked domain is pretty easy - in the nginx conf file, you'll need something like this:

server {
    listen        80;
    server_name   www.example.com;
    rewrite ^(.*) http://example.com$1 permanent;
}
server {
    listen        80;
    server_name   example.com;
...rest of your conf
}

You might not want to do this though. Using naked domains is not always the best idea.
