=== Standalone Mode

Standalone operating mode is only useful when you want to run one, and only one {{book.project.name}} server instance.
It cannot be made to run in a cluster and all caches are non-distributed and local-only.  It is not recommended that
you use standalone mode in production as you will have a single point of failure.  If your standalone mode server goes down,
users will not be able to log in.  This mode is really only useful to test drive and play with the features of {{book.project.name}}

==== Standalone Boot Script

When running the server in standalone mode, there is a specific script you need to run to boot the server depending on your
operating system.  These scripts live in the _bin/_ directory of the server distribution.

To boot the server:

.Linux/Unix
[source]
----
$ .../bin/standalone.sh
----

.Windows
[source]
----
> ...\bin\standalone.bat

==== Standalone Configuration

The bulk of this guide walks you through how to configure infrastructure level aspects of {{book.project.name}}.  These
aspects are configured in a configuration file that is specific to the application server that {{book.project.name}} is a
derivative of.  In the standalone operation mode, this file lives in _.../standalone/configuration/standalone.xml_.

NOTE: Any changes you make to this file while the server is running will not take effect and may even be overwritten
      by the server.  Instead use the the command line scripting or the web console of {{book.appserver.name}}.  See
      the link:{{book.appserver.admindoc.link}}[{{book.appserver.admindoc.name}}] for more information.


==== Standalone {{book.project.name}} Configuration

{{book.project.name}} has a json configuration file that is specific to {{book.project.name}} this is located within
_.../standalone/configuration/keycloak.json_.  This file is used to configure non-infrastructure level things that are
only applicable to {{book.project.name}}

NOTE: Any changes you make to this file while the server is running will not take effect.  You'll need to reboot the
      server.
