Overview of this book

GeoServer is an open source server-side software written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer allows you to display your spatial information to the world. Implementing the Web Map Service (WMS) standard, GeoServer can create maps in a variety of output formats. OpenLayers, a free mapping library, is integrated into GeoServer, making map generation quick and easy. GeoServer is built on Geotools, an open source Java GIS toolkit.GeoServer Beginner's Guide gives you a kick start to build custom maps using your data without the need for costly commercial software licenses and restrictions. Even if you do not have prior GIS knowledge, you will be able to make interactive maps after reading this book.You will install GeoServer, access your data from a database, style points, lines, polygons, and labels to impress site visitors with real-time maps.Follow along through a step-by-step guide that installs GeoServer in minutes. Explore the web-based administrative interface to connect to backend data stores such as MySQL, PostGIS, MSSQL, and Oracle. Display your data on web-based interactive maps, style lines, points, polygons, and embed images to visualize this data for your web visitors. Walk away from this book with a working application ready for production.After reading the GeoServer Beginner's Guide, you will have beautiful, custom maps on your website built using your geospatial data.

Time for action – improving security settings


  1. We will start by changing the default password for the administrator. Click on the Change it link on the left-hand side of the warning.

  2. A new page containing user properties will show up. Insert the new password in the Password and Confirm password textboxes and click on the Save button. You don't need to restart GeoServer or Tomcat; the new password is active now!

  3. The users.properties.old file is a security risk because it contains user passwords in plain text. GeoServer does not need it so it's safe to delete it.

    ~$ sudo rm /opt/apache-tomcat-7.0.27/webapps/geoserver/data/security/users.properties.old
    
  4. Now open the masterpw.info file. It contains the password generated by GeoServer for the root user. Store it in a secure place and delete the file.

    ~$ sudo rm /opt/apache-tomcat-7.0.27/webapps/geoserver/data/security/masterpw.info
