This topic explains how to configure a MySQL database as an external data source.

The MySQL Driver

LabKey Server requires the MySQL driver (called "MySQL Connector/J" in the MySQL documentation) to connect to MySQL databases. The LabKey Windows installer and manual install steps will copy the MySQL driver JAR file (mysql.jar) to your Tomcat installation, placing it in the <tomcat-home>/lib directory, making it available to your LabKey Server.

Detailed documentation about the driver is available at: MySQL Connector/J Developer Guide.

Configure the MySQL Data Source

Add a <Resource> element, to your installation's labkey.xml configuration file. Use the configuration template below as a starting point. Replace USERNAME and PASSWORD with the correct credentials. If you are running LabKey Server against a remote installation of MySQL, change the url attribute to point to the remote server.

Note: This template applies to Tomcat 8 (or later). If you are using Tomcat 7, use the earlier template version in the documentation archives.

    <Resource name="jdbc/mySqlDataSource" auth="Container"
validationQuery="/* ping */"

Note: the "zeroDataTimeBehavior=CONVERT_TO_NULL" parameter on the url above converts MySQL's special representation of invalid dates ("00-00-0000") into null. See the MySQL documentation for other options.

Define a New Schema

Now define a new schema from the MySQL data source. For details see Set Up an External Schema.
