This always shows the global value: SHOW VARIABLES LIKE ... This always shows the current session value: SHOW SESSION VARIABLES LIKE ...
Global value is read from the files when the server starts, and later can be changed with SET GLOBAL var = val. Session value is copied from global value when the session starts (so changing the global value doesn't affect existing sessions) and can later be changed with SET var = val. In other words, the global value is important because it is used by all new sessions by default, but the session value is what really takes effect. I beleive that your application sets a session value.

On Debian, mysql-common package provided by MariaDB repository contains "wait_timeout = 600" in my.cnf. This is not the default value specified in documentation (28800). And when I use "mysql -u root -p -h my_host" command to show variables, the default value is displayed (28800), I never saw 600 in here ! Why ? But displaying variables in my PHP app showed me that wait_timeout was effectively set to 600. Setting wait_timeout=28800 in a config file in /etc/mysql/conf.d directory fixes this. Should we consider "wait_timeout = 600" in my.cnf as a bug ? That's not default value... On 11/29/2016 11:17 PM, Federico Razzoli wrote: > Interesting.
