in php.ini

[Session] ; Handler used to store/retrieve data. session.save_handler = files

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP‘s session functions.
;
; As of PHP 4.0.1, you can define the path as:
;
; session.save_path = “N;/path”
;
; where N is an integer. Instead of storing all the session files in
; /path, what this will do is use subdirectories N–levels deep, and
; store the session data in those directories. This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
;
; NOTE 1: PHP will not create this directory structure automatically.
; You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
; use subdirectories for session storage
;
session.save_path = /tmp/ <= HERE YOU HAVE TO MAKE SURE
