Php Session File Permissions

Question

I have an index.php file:

<?php    
session_start();
$_SESSION['favcolor'] = 'green';

And I get the result:

Warning: session_start() [function.session-start]: open(/tmp/sess_a8njkmbcg3lbkvl7f2hhjchjm5, O_RDWR) failed: Permission denied (13) in /var/www/test.local/index.php on line 9
Warning: Unknown: open(/tmp/sess_a8njkmbcg3lbkvl7f2hhjchjm5, O_RDWR) failed: Permission denied (13) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

php.ini

root@savpc:/etc/php5/apache2# cat php.ini | grep '^session'
session.save_handler = files
session.save_path = "/tmp"
session.use_cookies = 1
session.use_only_cookies = 1
session.name = PHPSESSID
session.auto_start = 0
session.cookie_lifetime = 0
session.cookie_path = /
session.cookie_domain =
session.cookie_httponly =
session.serialize_handler = php
session.gc_probability = 0
session.gc_divisor = 1000
session.gc_maxlifetime = 1440
session.bug_compat_42 = Off
session.bug_compat_warn = Off
session.referer_check =
session.entropy_length = 0
session.cache_limiter = nocache
session.cache_expire = 180
session.use_trans_sid = 0
session.hash_function = 0
session.hash_bits_per_character = 5

in the file system, I get files with strange permissions :

root@savpc:/tmp# ls -al | grep 'sess'

• Ubuntu 11.10
• Apache Version: Apache / 2.2.20 (Ubuntu)
• PHP Version 5.3.6-13ubuntu3.10

What could be the problem?

Answer 1

• Use a specific folder for sessions, for example / tmp / php _sessions. This is a good maintenance at home, and for security reasons.

• Try specifying the file mode in session.save_path.

  session.save_path = "0;0600;/tmp/php_sessions"
  

  See the session configuration in the PHP manual for details .

Answer 2

session.save_path = "D:/wamp/tmp"
<br>
D:/wamp/tmp  Change Temp Directory Or Give Permission up in this directory
<br>
PHP Cannot Access to This folder in Your Server...
<br>
D:/wamp/tmp !!! is Sample Directory

Find session.save_path or change access ...

Answer 3

chmod 777 /tmp

/tmp.

Answer 4

Try to create another folder to use for www data and set the save path to this.

also see if your php has an umask parameter. i ni if ​​it is set to 022
