nginx server configuration: subdomain to folder - nginx

Question

I migrated from Apache 2 to nginx and I've got problems to handly my subdomain control.
What I want: When x.domain.tld is requested, internally rewrite to domain.tld/x
The problem I've got is that nginx always redirects the page by telling the browser to redirect to. But what I really want is to do this internally, like Apache 2 did.
Also, if I only request x.domain.tld, nginx returns a 404. It only works when I do x.domain.tld/index.php
Here's my config:
server {
listen 80 default;
server_name _ domain.tld www.domain.tld ~^(?<sub>.+)\.domain\.tld$;
root /home/domain/docs/;
if ($sub) {
rewrite (.*) /$sub;
}
# HIDDEN FILES AND FOLDERS
rewrite ^(.*)\/\.(.*)$ #404 break;
location = #404 {
return 404;
}
# PHP
location ~ ^(.*)\.php$ {
if (!-f $request_filename) {
return 404;
}
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/etc/nginx/sockets/domain.socket;
}
}
Thanks!

As I found this Q&A on Google while looking for a solution for the same problem, I wanted to post the solution I finally used.
The first server block by MTeck looks pretty nice, but for the subdomains part you could simply do the following:
server {
listen 80;
server_name "~^(?<sub>.+)\.domain\.tld$";
root /path/to/document/root/$sub;
location / { try_files $uri $uri/ /index.php; }
location ~ \.php {
include fastcgi_params;
fastcgi_pass unix:/etc/nginx/sockets/domain.socket;
}
}
This makes the root configuration directive dependent on the subdomain.

I spent hours beating my head against the wall and this is what works for me
server {
listen 80;
server_name ~^(?P<sub>.+)\.example\.com$; #<-- Note P before sub, it was critical for my nginx
root /var/www/$sub; #<-- most important line cause it defines $document_root for SCRIPT_FILENAME
location / {
index index.php index.html; #<-- try_files didn't work as well
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000; #<-- probably you have another option here e.g. fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
include fastcgi_params;
}
}

You should take a look at http://wiki.nginx.org/IfIsEvil. You're doing a whole lot wrong in this configuration file.
server {
server_name domain.tld www.domain.tld;
location / {
try_files $uri /index.php;
}
location ~ \.php {
include fastcgi_params;
fastcgi_pass unix:/etc/nginx/sockets/domain.socket;
}
}
server {
server_name "~^(?<sub>.+)*\.(?<domain>.*)$";
return 301 $scheme://$domain/$sub$request_uri;
}
If what you want is to keep that internal, you won't be able to rewrite it. By definition, a cross site rewrite needs to be sent back to the browser. You'll have to proxy the request.
server {
server_name "~^(?<sub>.+)*\.(?<domain>.*)$";
proxy_pass http://$domain/$sub$request_uri;
}
You should read the Nginx wiki. All of this is explained in depth.

This will work for www also.
server {
listen 80 default_server;
listen [::]:80 default_server;
index index.php index.html index.htm index.nginx-debian.html;
server_name ~^www\.(?P<sub>.+)\.domain\.com$ ~^(?P<sub>.+)\.domain\.com$;
root /var/www/html/$sub;
location / {
try_files $uri $uri/ /index.php?$args;
}
}
