Answer 1

I am running Fedora 18 with PHP 5.4 (using php-fpm) + nginx and I faced similar problem. Symfony was complaining that it was unable to create a session file called /var/lib/php/session/sess_

I gave apache rwx permission to /var/lib/php/session using the following acl command and it solved the problem:

sudo setfacl -m apache_username:rwx /var/lib/php/session 

apache_username is either apache, www-data depending on your linux distribution, it can be also a custom user

Answer 2

just have to add/change these 2 lines in app/config/config.yml to fix it:

framework:
session:
    handler_id: session.handler.native_file
    save_path: "%kernel.root_dir%/sessions"

Answer 3

i think when it comes to symfony deployment errors, in most cases the problem is permissions.

in this case i changed permission of the folder in witch sessions were being saved and now everything works fine.
