Modify the MySQL data directory

The data directory for MySQL is set to /opt/bitnami/mysql/data by default. You can modify the location of this folder modifying the /opt/bitnami/mysql/my.cnf file, as shown below:

...
datadir=/opt/bitnami/mysql/data
...

Also modify the /opt/bitnami/mysql/scripts/ctl.sh file to reflect the new directory location:

--datadir=/opt/bitnami/mysql/data

Finally, move the data/ directory to the new location and restart the database.
