phpMyAdmin No activity within 1440 seconds; please log in again. Issue

Question

I have installed latest phpMyAdmin on Apache+php+mysql on CentOs.

But after sometime of inactivity i am getting

No activity within 1440 seconds; please log in again.

And redirected to the phpMyAdmin Log-In page.

I have Edited /etc/php.ini and set

session.gc_maxlifetime 999999

and did HTTPD restart.

But still i am getting the same error. How do i fix this ?

How do i make the phpMyAdmin session for like 20+ days, as its a production environment.

Thanks

Answer 1

The same problem has been annoying me for weeks, but I think that I now have the answer, at least for the latest versions of phpMyAdmin (I currently have version 4.1.14). You need to change settings->features->Login cookie validity. The way that you get to this setting is as follows:

1) Login to phpMyAdmin
2) From the home screen click on "More settings" (middle bottom of screen for me)
3) Click the "Features" tab/button towards the top of the screen.
4) For 20 days set the "Login cookie validity" setting to 1728000
5) Apply.

Hope that helps?
