phpMyAdmin configuration

How to set phpMyAdmin default 1440 second timeout higher:

1. locate php.ini

   el@apollo:/var/lib/phpmyadmin$ locate php.ini
   /etc/php5/apache2/php.ini
   

2. open the file as root to edit, find this line:

   session.gc_maxlifetime = 1440
   

3. Change it to this (500000 seconds is 5.7 days)

   session.gc_maxlifetime = 500000
   

4. Restart apache.

Doing this decreases security because then it increases opportunity for cross site scripting and man in the middle attacks. It's all fun and games until you find your server is part of a botnet farming for credit cards.

config.inc.php > $cfg['LoginCookieValidity'] = 3600 * 9; // 9 hours

edit from the link posted by ajreal: LoginCookieValidity

for the second question , after changing upload_max_filesize in php.ini did you restart apache ( or whatever webserver you use ) ?
