phpMyAdmin is one of my favorite tools and I use it all the time. But man, the 24-minute session timeout is a huge problem . A short cookie lifetime is all well and good on your production server, but what about when you’re just testing new things away on the computer in your test envirnment?
Did a little
grepping and found that you can override
this setting, even though it’s not documented anywhere but in the codes
(so far as I can tell). To override it, just open up config.inc.php in the root phpMyAdmin directory and add this setting (anywhere, but mostly at end of file):phpmyadmin config file for ubuntu Server : /etc/phpmyadmin/config.inc.php
$cfg['LoginCookieValidity'] = <your_new_timeout>;Where
<your_new_timeout> is some number larger than 1800. Personally, I chose 28800, which is 8 hours.Define how long a login cookie is valid. Please note that php configuration option session.gc_maxlifetime might limit session validity and if the session is lost, the login cookie is also invalidated. So it is a good idea to set session.gc_maxlifetime at least to the same value of $cfg['LoginCookieValidity'].
php.ini file for ubuntu Server : /etc/php5/apache2/php.ini
Disclaimer! It should go without saying that increasing the timeout is a (comparatively minor) security risk (but a risk nonetheless). Obviously, do not do this on your production server. And as always, proceed with caution.
