Hello,
copying my post in russian here as well.

I spend a lot of time trying to configure following scenario -

*.domain.com should take files from /srv/www/vhosts/domain.com/*/
also PHP files should be handled by apache with same scenario.

So currently it works super fine on pure apache with following rewrite rule

RewriteEngine On
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com
RewriteCond /srv/www/vhosts/domain\.com/%1 -d
RewriteRule ^(.*) /%1/$1 [L]

and I wish to install nginx as frontend (it should server static, not just proxy)

I found 2 options
1)
server {
listen 80;
server_name ~^(.*)\.nginxdomain\.com$;
#if directory doesn't exist
if (!-d /home/domains/nginxdomain.com/public/$1) {
rewrite . http://www.nginxdomain.com/ redirect;
}

# Sets the correct root
root /home/domains/nginxdomain.com/public/$1;

it doesnt work, when for example I request picture.jpg Nginx searhes for file under ../domain/jpg/.. (jpg instead of subdomain)
or if picture.png it would got to ../domain/png/..

2)
if ($host !~* ^www\.domain\.tld$) {}
if ($host ~* ^([^.]+)\.domain\.tld$) {
set $auto_subdomain $1;
}
if (-d /var/www/domain.tld/www/$auto_subdomain) {}
if (-f /var/www/domain.tld/www/$auto_subdomain$uri) {
rewrite ^(.*)$ /$auto_subdomain$uri;
break;
}

I dont really understand this, but it doesnt work like that.


I would appreciate any help,

thanks,
Igor S.

if ($host ~* ^([^.]+)\.facebook\.rc\.77test\.co\.uk$) {
set $auto_subdomain $1;
}
root /srv/www/vhosts/facebook.rc.77test.co.uk/$auto_subdomain/;



this seems to be working properly, can someone advice is it fine in terms of performance, if I ll have more than 100 subfolders.

thanks.

@Ancient - your approach worked for me.
I am also wondering if there is any performance issue with this.
I know explicit location blocks for each subdomain is the best performance, but for practical reasons the above config is very useful.
Any issues with it?

We have been running it on production server for a week now without problems. Server load decreased by ~30%.
