MapServer Quickstart
MapServer is an `Open Source <https://opensource.org/>`_ server based application that allows you to publish geographic map images and vector data through the Internet using |OGCS| such as |WMS|, |WFS| and |WCS|.

Configure MapServer using the Mapfile configuration file
**What will I learn ?** In this section, you will learn what a Mapfile is and how to configure it to allow MapServer to serve a shapefile as images using WMS requests.
What is a Mapfile ?
The `Mapfile <https://mapserver.org/mapfile/index.html>`_ is the configuration file that MapServer uses to render geospatial data as images or vector data. Its main purpose is to define the layers it can draw, how to read necessary data, and how to render it (e.g. color, symbol, label, etc...).
Creating my first Mapfile
Open any text editor (e.g. :menuselection:`Accessories --> FeatherPad`).
Create the file "mapserver_quickstart.map" at the following location: :file:`/home/user/mapserver_quickstart.map`
Put the following content in it::
The example uses the natural earth dataset, which is already on OSGeoLive at :file:`~/data/natural_earth2` (a short cut to :file:`/usr/local/share/data/natural_earth2`).
Each object in a Mapfile starts with its name (for example **MAP**) and ends with an **END**. A Mapfile always starts with the **MAP** object and should contain a list of **LAYER** objects the Mapfile can read and draw. In our Mapfile, we currently have only one layer defined.
Let's take a look at some of the objects (and properties) defined in our Mapfile:
EXTENT: sets the default geospatial bounding box for this configuration.
LAYER: defines access and display properties for a spatial dataset. We'll add another layer later.
SHAPEPATH: sets a base path for file-based data (e.g. shapefiles or GeoTIFF images).
If we look closer at the **LAYER** in our Mapfile, we'll see that it contains a bunch of properties and objects too. Among them are:
STATUS: defines whether the layer can be drawn (*ON*), can't be drawn (*OFF*) or is always drawn (*DEFAULT*).
TYPE: the geometry type that MapServer should use when rendering the data as an image. In our Mapfile, the data will be drawn as *polygons*.
DATA: the name of the spatial data file this layer uses, in this case a shapefile.
CLASS: determines how to draw a layer (styling). We'll cover this object in more detail later.
