# Step 3: Start Pentaho Server and install licenses and client tools

The Pentaho Server is located on the Pentaho-provided Tomcat web application server.

The way you start the Pentaho Server depends on your operating system.

1. Navigate to the `<your pentaho directory>/server/pentaho-server` folder.
2. Run the startup script for your operating system:

   * Windows: `start-pentaho.bat`
   * Linux: `start-pentaho.sh`

   The Tomcat web application server and the Pentaho Server start.
3. From a workstation, open a web browser and enter `http://localhost:8080/pentaho` in the address bar.

   If your server has a different hostname or port, replace `localhost` or `8080`.
4. Enter your user name and password, then select **Login**.

   The Pentaho User Console (PUC) opens.

   Upon first login after installation, enter a license server code or individual license keys.

See the [Administer Pentaho Data Integration and Analytics](https://app.gitbook.com/o/PtpmPYUKgAsUWgv8SVUt/s/iFWuQjAZNxh1EoQbRnsT/) document for license setup and optional Operations Mart logging.

If you have problems starting the Pentaho Server, see [Troubleshooting possible installation and upgrade issues](https://docs.pentaho.com/install/pentaho-installation-overview-cp/installation-and-upgrade-issues).

### Install client tools

After you install and start the Pentaho Server, install the Pentaho client tools on separate workstations.

* [Install PDI client, utilities, and plugins](https://docs.pentaho.com/install/installation-of-the-pentaho-design-tools#install-pdi-client-utilities-and-plugins)

After you install the server and client tools, configure access, licenses, and data sources, see [Pentaho configuration](https://docs.pentaho.com/install/pentaho-configuration).
