Why is Mysql eating RAM?

Question

MySQL

That's where 9.7 -% of the total memory. There is a similar question but there is no solution.
In which direction should I dig in the config? Connection 1-o.

Answer 1

The normal state is that mysql eats RAM. No need to add up the consumed megabytes - this is shared memory (well, or something like that is called).
In general, if 602 meters are shown, it means that for all streams, and not for each separately.
In this case, it is necessary to distinguish between allocated, reserved, used memory.
sudo apt-get install mysqltop
sudo mysqltop

Answer 2

This is normal behavior.
Run mysqltuner.pl - it will give you, among other things, a breakdown from memory, how much the server needs and why ...
If you do not have mysqltuner.pl -
wget mysqltuner.pl -o mysqltuner.pl
;)

Answer 3

you don’t understand what’s on the screen, it’s more clear that this is the top / htop output in which the mysqld server threads are displayed, but it’s not at all clear why you decided that it eats more RAM than necessary
