Follow these instructions to configure your Liferay portal with MySQL SGBD :

  • Downloading the jdbc Driver

For MySQL, there is no need to download the jdbc driver. When Liferay detects you want to use MySQL, it will automatically include the driver (mysql.jar) in your $TOMCAT_HOME/lib/ext.

  • Creating the blank database

Create a blank database using the UTF-8 encoding and give it a name. Let’s consider that the created database is “lportal”.

  • Updating portal-ext.properties

Open your portal-ext.properties file and past the following lines :

Set the correct username and password to connect to your database.

The portal-ext.properties is located in the same folder as your $TOMCAT_HOME. If it doesn’t exist, create it.

portal-ext.properties location

  • Check the configuration

During the server start, you can check that Liferay started with the appropriate dialect by looking for the following lines in your server log console/file:

If you go back to your database, you will see that it’s now populated by about 180 data tables that Liferay created on startup.

If you already configured your portal with hsql and want to re-configured it with the MySQL Database and add samples data, open portal-setup-wizard.properties file located in the same folder as  portal-ext.properties. Set the setup.wizard.enabled to true and restart your server.
