### Issue Details

Template installs but a bit confused on how to connect. I can ssh into a single vm but not to the cluster. The user account doesn't seem to allowed to connect as root mysql. Can you please give guidance on how to use this.

Here are the base wordpess that i would like to create the first database with
// *\* MySQL settings - You can get this info from your web host *\* //
/*\* The name of the database for WordPress _/
define('DB_NAME', 'database');
/_\* MySQL database username _/
define('DB_USER', 'username');
/_\* MySQL database password _/
define('DB_PASSWORD', 'password');
/_\* MySQL hostname */
define('DB_HOST', 'tprperconadb.westus.cloudapp.azure.com');

Start with the mysql-ha-pxc template linked in the issue and review how the deployed cluster is intended to be accessed. Determine the supported connection method and credentials for creating the WordPress database, then document the steps and connection values needed to connect successfully.
