Hello, I’m using this nginx conf:

root /var/www/html/laravel/public;

        index index.php index.html index.htm index.nginx-debian.html;

        server_name *.example.com;

        location / {
                try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.1-fpm.sock;
        }

It is multi-tenancy project, I want redirect all subdomains with www to non-www. My question is, how? :) I have one config file for all subdomains.

In my root nginx conf I just used: 

server {
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

But in subdomains config I cant use it. My nginx conf skills are not very good, so pls help.

Thank you all

    Not sure what you mean here:

    But in subdomains config I cant use it.

    There is no such thing as “subdomains” conf. Every site (virtual host) should have its own configuration file.

If someone need this, solution is:

if ($host ~* ^www\.(.*)) {
                set $host_without_www $1;
                rewrite ^(.*) http://$host_without_www$1 permanent;
}

Hello, thanks.

But I think we did not understand each other :)

What I need is redirect from www subdomain to non www subdomain, not to domain.

So:

www.sub.example.com redirect to sub.example.com
www.sub2.example.com redirect to sub2.example.com

and NOT:

www.sub.example.com to example.com

But I dont have conf files for each of this subdomains. I have only one sub nginx conf as I mentioned in my first question.

Thank you.

You can target all www.*.domain.com hostnames by using a regular expression:

server {
    listen 80;
    server_name ~^www\..+\.domain\.com$;
    return 301 $scheme://domain.com$request_uri;
}

Make sure you escape any dots in your domain name by adding a \ before them like in the snippet above.

    This doesn’t seem to work for me. I put it in the default.conf without success.
    We want to redirect like this:

    www.sub.example.com redirect to sub.example.com
www.sub2.example.com redirect to sub2.example.com

redirect 301 subdomain www to non www
RewriteCond %{SERVER_PORT} ^80$

RewriteCond %{HTTPHOST} ^subdomain.domain.com$ [NC]
RewriteRule .? https://%{HTTPHOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{HTTPHOST} ^www.([^.]+.domain.com)$ [NC]
RewriteRule ^ http%{ENV:protossl}://%1%{REQUESTURI} [R=301,L]
