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.

Note that version 8.0 of the driver changed the class name from "com.mysql.jdbc.Driver" to "com.mysql.cj.jdbc.Driver". The newer version is recommended, but be sure to use the appropriate class name for the deployed version.

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.

    <Resource name="jdbc/mySqlDataSource" auth="Container"
        type="javax.sql.DataSource"
        username="USERNAME"
        password="PASSWORD"
        driverClassName="com.mysql.cj.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf8&amp;zeroDateTimeBehavior=CONVERT_TO_NULL"
        maxTotal="15"
        maxIdle="7"
        useInformationSchema="true"
        accessToUnderlyingConnectionAllowed="true"
        validationQuery="/* ping */"
    />

Define a New Schema

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