I've noticed something in recent JumpBox builds.
The password supplied by this command:
sudo grep password /etc/mysql/debian.cnf
only works when using username: debian-sys-maint.
It will not work if you try to log in to MySQL as root or admin or anything else.
This seems to apply on other JumpBoxes as well as the OTRS one.
MySQL Access
I believe you can set the root mysqluser password as the debian-sys-maint user ... but you should be able to do this ...
Note: This restarts the mysql server.
Another method:
I am pretty sure as debian-sys-maint:
the SQL statment
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('biscuit');will do it.
