Answer by Beltran Rueda

Try the following.

1. Log in the Virtual Appliance and run the following command:

$ mysql -u root -p -e "grant all privileges on *.* to 'root'@'%' identified by 'bitnami'";

1. Then edit the /opt/bitnami/mysql/my.cnf file and remove the following line. You can edit with "nano":

   bind-address = 127.0.0.1

2. Run the following command to open the 3306 port for the Virtual Appliance firewall:

   $ sudo ufw allow 3306

That's all, you should be able to connect to the database using the user "root" and the password "bitnami". I hope it helps.
