According to [Pitfalls and Common Mistakes | NGINX](http://wiki.nginx.org/Pitfalls#Server_Name) this is the best  
solution to redirect www to no-www for one domain:

server {  
server\_name [www.domain.com](http://www.domain.com);  
return 301 $scheme://domain.com$request\_uri;  
}  
server {  
server\_name [domain.com](http://domain.com);  
[…]  
}

Is there a way to do this with regex or variables? I’ve ~15 domains and  
it  
would be more convenient to have only one entry “to rule them all” 😉

Absolutely there are ways to do this all in one go. Have a try and let  
us  
know where you get stuck 🙂

As a newbie to NGINX (used 10yrs APACHE before) i don’t know the exact  
route  
on the wiki & forum ;-). I also not found a newbie-section 😉 But off  
course, i shall post the solution.

Sajan tells about $host, i’ll give it a try

I should correct my server\_name line. It should not have the variable,  
but the actual domain names. So I guess you’ll still have to come back  
and add each domain.

Sorry. On phone.

Haven’t testing this, but would you not be able to replace ‘[domain.com](http://domain.com)’  
with $host?

server {  
server\_name www.$host;  
rewrite ^(.\*) $scheme://$host$request\_uri permanent;  
}

That should work I think. Right now, I do it the way you’ve descrived  
individually in all my .conf files for each domain.

the regex way, which is supposedly slower:

server {  
server\_name ~^www.(?.+)$;  
listen 80; listen [::]:80;  
return 301 $scheme://$domain$request\_uri;  
}

‘supposedly slower’ is a very good argument to not use RegEx 😉 Do you  
have  
a source for that?
