The data directory for MySQL is set to installdir/mysql/data by default. You can modify the location of this folder modifying the installdir/mysql/my.cnf file, as shown below:
...
datadir=installdir/mysql/data
...
Also modify the installdir/mysql/scripts/ctl.sh file to reflect the new directory location:
--datadir=installdir/mysql/data
