i copied the sample connection from the cookbook. It includes mysql as driver. Here’s what’s in my app_local.php as part of my dataconnections:
/**
* The debug_kit connection stores DebugKit meta-data.
*/
'debug_kit' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'mysql.bytecamp.net',
//'port' => 'nonstandard_port_number',
'username' => '#myuser', // Your DB username here
'password' => '#mypassword', // Your DB password here
'database' => '#mydb',
'encoding' => 'utf8',
// 'timezone' => 'UTC',
'cacheMetadata' => true,
'quoteIdentifiers' => false,
//'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
],
