## Running Jetty

Once you have a copy of the Jetty distribution downloaded, extract the `zip` or `tar.gz` file to a location where you have read and write access. Jetty has no GUI (Graphical User Interface), so running the server and performing many configuration options is done from the command line.

Once you have access to your system’s command line, navigate to the directory where you unpacked your copy of the Jetty distribution. To start Jetty on the default port of 8080, run the following command:

    $ java -jar start.jar
    2017-09-20 15:45:11.986:INFO::main: Logging initialized @683ms to org.eclipse.jetty.util.log.StdErrLog
    2017-09-20 15:45:12.197:WARN:oejs.HomeBaseWarning:main: This instance of Jetty is not running from a separate {jetty.base} directory, this is not recommended.  See documentation at http://www.eclipse.org/jetty/documentation/current/startup.html
    2017-09-20 15:45:12.243:INFO:oejs.Server:main: 9.4.27.v20200227

    2017-09-20 15:45:12.298:INFO:oejs.Server:main: Started @995ms

You can point a browser at this server at http://localhost:8080. However, as there are no webapps deployed in the `$JETTY_HOME` directory, you will see a 404 error page served by Jetty. To stop the server, press `CTRL` + `c` or `CTRL` + `z` in your terminal.

Note the `HomeBaseWarning` - it is not recommended to run Jetty from the `$JETTY_HOME` directory. Instead, see how to create a Jetty Base below.

> ### Note

> You will see examples throughout the documentation referencing `$JETTY_HOME` and `$JETTY_BASE` as well as `{jetty.home}` and `{jetty.base}`. These terms are used to refer to the location of your Jetty installation directories. Many users find it helpful to define `$JETTY_HOME` as an environment variable that maps to their Jetty distribution directory. More information can be found in our Administration section on managing Jetty Home and Jetty Base.

### Demo Base

Within the standard Jetty distribution there is the `demo-base` directory. This is a fully-functioning Jetty Base (more on that later) complete with numerous web applications demonstrating different Jetty functionality. Additionally, the `demo-base` demonstrates the recommended way to run a Jetty base in a directory separate from `$JETTY_HOME`:

    $ cd demo-base/
    $ java -jar ../start.jar

You can visit this demo server by pointing a browser at http://localhost:8080, which will now show a welcome page and several demo/test web applications.

> ### Warning

> The demonstration web applications are not necessarily secure and should not be deployed in production web servers.

You can see the configuration of the `demo-base` by using the following commands:

    > cd $JETTY_HOME/demo-base/
    > java -jar $JETTY_HOME/start.jar --list-modules
    ...

    > java -jar $JETTY_HOME/start.jar --list-config
    ...

The `--list-modules` command will return a complete list of available and enabled modules for the server. It will also display the location of the modules, how and in what order they are implemented, dependent modules, and associated jar files.

The `--list-config` command displays a trove of information about the server including the Java and Jetty environments, the configuration order, any JVM arguments or System Properties set, general server properties, a full listing of the Jetty server class path, and active Jetty XML files.
