I have a virtual box with 2 installed instances of MySQL.
First instance:
- /etc/mysql/my.cnf
- /var/lib/mysql
- port = 3306
Second instance:
- /etc/mysql2/my.cnf
- /var/lib/mysql2
- port = 3307
I can connect to both. The first instance is fine. The second is not.
MySQL doesn't ignoring some params from my.cnf
file (socket, port, pid-file, data-dir…). But if I'm trying to change something else: cache, buffers, log files it completely ignores changes after restarting.
I need to make MySQL read all params from my.cnf.
I tried:
– to move my.cnf
from /etc/mysql
to /var/lib/mysql
;
– commenting out !includeir /etc/mysql/conf.d
.
Could someone guide me?

I had a similar problem with a box I was diagnosing for performance issues, it turned out that there was an incorrect / misplaced heading entry within the my.cnf for that server, so MySQL was ignoring all the settings within that section...
For example, if you had the following;
Then the buffer tuning section is ignored as it is within the
client
section and not themysqld
section... Re-arrange the sections, and all works as intended.Hopefully, it is as simple as this for you!
