Setting proper path in Nginx for Symfony2 - symfony

Question

I need to have my symfony app installed on the same domain as other webapps so I wanted it to sit in /dev/symfony_app path
I tried to use NginX Friendly PHP Framework but solutions from there do not work.
I have such nginx config and it does not work at all too. there is some problem with paths, nor root neither alias directive work for me.
location /dev/symfony_app/ {
root /home/.../public_html/web;
}
location ~ ^/dev/symfony_app/(app|app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
fastcgi_param HTTPS off;
}
nginx error log:
request http://domain.com/dev/symfony_app/

Well, what are the dots doing there in your path? You can’t have a directory with three dots as name (at least this would be new to me). The error message from nginx is very specific in that regard. That path doesn’t exist.
server {
listen 80;
server_name _;
root /home/public_html/web;
location / {
location ~* ^/dev/symfony_app/(app|app_dev|config)\.php$ {
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass unix:/var/run/php-fpm.sock;
}
}
}
That should do the trick.
The absolute local path to the index file of your Symfony installation has to be /home/public_html/web/dev/symfony_app/index.php. A request to http://example.com/dev/symfony_app will map the above location.
I hope this helps, otherwise please leave a comment and describe what else is going wrong.
