AWS EC2 PHP : Unable to set the session value, but session id is generating

Question

I have hosted my code igniter application in AWS EC2. In that session is not setting the values in my login process. In php.ini file, i have set the session save path to /tmp.

session.save_path = '/tmp'

Session started and session id is generating. But session values are not storing.I have printed the $_SESSION and session id, below is the output.

string(26) "038vbmtjecvkqft02ou813qvo1" array(1) { ["__ci_last_regenerate"]=> int(1540479344) }

I have my session code as follows,

$this->session->set_userdata('frontusername', $res->Email);
$this->session->set_userdata('frontname', $res->FirstName);
$this->session->set_userdata('frontuserid', $res->Id);

Its working fine in my another server, but not here in AWS EC2. Have restared the apache after setting the save path and checked the error log under /var/log. No error. Also /tmp folder is writable.

My php.ini file,

Searching for last two days, no luck. Any help please, thanks in advance.

Can you show us the source code of the class you're using for session handling in `$this->session`? — nevada_scout, Oct 25 '18 at 16:09
@vivek_23, yes, $_SESSION prints only __ci_last_regenerate, not my values — devkann, Oct 25 '18 at 16:17
i am using php 7 in ec2 and php 5 in my another server. anything related to this? — devkann, Oct 25 '18 at 16:18
@nevada_scout, Not only for ci $this->session class, also by using $_SESSION['frontusername'], the same issue. — devkann, Oct 25 '18 at 16:20
@devkann Is there an error being logged when you try to access the session variables? If you do `$_SESSION['frontusername'] = "test";` does it still not work? — nevada_scout, Oct 25 '18 at 16:24
@nevada_scout, no error. $_SESSION['frontusername'] = "test" not working — devkann, Oct 25 '18 at 16:50
@devkann Might be a silly question, but are you sure `session_start()` is being called before you try to get/set session data? — nevada_scout, Oct 25 '18 at 19:49
@nevada_scout, yes, session_start() is calling, because i am able to get the session_id. — devkann, Oct 26 '18 at 03:20
whats session permission. have you set it to 777. if not change it and try — prasanna puttaswamy, Oct 29 '18 at 05:42
@prasannaputtaswamy, You mean for /tmp folder. Yes its 777. Inside that its having as /tmp/systemd-private-5bce9acafc2a4fafa74947e9950cefdf-apache2.service-OL9Au7. Whether the session would be written inside this? — devkann, Oct 30 '18 at 03:37

Check permission for session. I had the same problem and solved it by changing permission in ami.

The local value pointing /var/lib/php/session seems to be the problem as this directory is not writable by server user. I did not know anything about local and master value, and after some digging in google I read the following:

"Master Value" (from php.ini) could be overridden with "Local Value" in httpd.conf, .htaccess or other Apache configuration with php_value directive.

So after looking around server files i found /etc/httpd/conf.d/php.conf which contains:

#
Apache specific PHP configuration options
those can be override in each configured vhost
#
php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"

So there is the problem, this php.conf is overwritting default php.ini configuration. I can comment this last line wih "#" and restart the server and all is working as expected again.

Hope this help.

Are you sure that the session is start ai the beginning of the file with session_start()? – Weber Oct 26 '18 at 19:05
