Nginx virtual host config

This has been working for me for some time now. It enables virtual hosts to be dynamically added to your server, serve PHP files and set expires on assets.

There is no need to set up directories for www.example.com in addition to example.com, this does the rewrite for you.

server {
    listen 80;
    server_name _;
    server_name_in_redirect off;
  
    # remove www. off the front
    set $domain $host;
    if ( $domain ~ "^(w{3}\.)?(.*)") {
      set $domain $2;
    }
  
    root /var/www/vhost/$domain/htdocs;
  
    location / {
      root /var/www/vhost/$domain/htdocs/;
      index index.html index.php;
    }
  
  
    # serve static files directly
    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html)$ {
      expires 30d;
    }
  
  
    location ~ \.php$ {
      include /etc/nginx/fastcgi_params;
      fastcgi_param  SCRIPT_FILENAME  /var/www/vhost/$domain/htdocs/$fastcgi_script_name;
      fastcgi_pass   127.0.0.1:8001;
      fastcgi_index  index.php;
    }
  
  }
