(v24) Manage the MySQL Connector

Manage the MySQL Connector

The Composer MySQL connector lets you access the data available in MySQL databases using the Composer client. The Composer MySQL connector supports MySQL versions 5.6 - 8.0.

Before you can establish a connection from Composer to MySQL storage, a connector server needs to be installed and configured. See Manage Connectors and Connector Servers for general instructions and Connect to MySQL for details specific to the MySQL connector.

After setting up the connector, create data sources that specify the necessary connection information and identify the data you want to use. See Manage Data Sources for more information. After you set up your data sources, create dashboards and visuals from from the data in these data sources. See Create Dashboards.

Connect to MySQL

The MySQL connector requires a JDBC driver to be configured before you can connect to your data source.

1. Download and install the version latest JDBC driver from https://dev.mysql.com/downloads/connector/j/. Instructions are provided on that website.

2. After installing the driver, edit the MySQL properties file and change the driver path and class name properties, as shown below and as described in Add a JDBC Driver:

   datasource.driver-config.class-name=com.mysql.cj.jdbc.Driver datasource.driver-config.jar-path=<JDBC_driver_filepath>

3. Save the properties file and restart the connector. See Add a JDBC Driver.
