=== Before You Start Before you can participate in this tutorial, you need to complete the installation of {{book.project.name}} and create the initial admin user as shown in the <> tutorial. There is one caveat to this. You have to run a separate {{book.appServer}} instance on the same machine as the {{book.project.name}} server. This separate instance will run your Java Servlet application. Because of this you will have to run the {{book.project.name}} under a different port so that there are no port conflicts when running on the same machine. Use the `jboss.socket.binding.port-offset` system property on the command line. The value of this property is a number that will be added to the base value of every port opened by the {{book.project.name}} server. To boot the {{book.project.name}} server: .Linux/Unix [source] ---- $ .../bin/standalone.sh -Djboss.socket.binding.port-offset=100 ---- .Windows [source] ---- > ...\bin\standalone.bat -Djboss.socket.binding.port-offset=100 ---- After booting up {{book.project.name}}, you can then access the admin console at http://localhost:8180/auth/admin/
