Please refer blow points:
1. First, add/install the mySQL ODBC driver to create a new mySQL ODBC connection (MySQL :: Download Connector/ODBC).
2. Perform the settings for the ODBC connection (you can use an IP address for the database server)
3. Access the ODBC connection in the Script dialog in Qlikview as per any other live data source
4. Once everything is in place then Load the data in Qlik app and get started.
Hope this will be of help.
