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

The MySQL JDBC Driver

LabKey Server requires the MySQL JDBC driver (called "MySQL Connector/J" in the MySQL documentation) to connect to MySQL databases. The MySQL JDBC driver JAR file (mysql.jar) must be copied to your Tomcat installation in the <tomcat-home>/lib directory.

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.
