How to specify xampp mysql port number during bitnami wordpress installation?
During the WordPress installation process, you should select the directory where your XAMPP is installed. If you select a directory that contains a XAMPP installed using non-default ports (for example Apache [81,444] and MySQL [3307]), WordPress installation will use the same ports that are defined in the configuration files inside the XAMPP directory.
As of Jul'17 there is no way to specify MySql port number. Following is the response I got from Bitnami Developer:
I am afraid that we do not support a different port by default. My advice would be to restart mysql in port 3306, perform the installation and then switch it back to your custom port. Note that you will also need to change the wp-config.php file so it uses the proper database port. Would that work for you?
