=== Standalone Clustered Mode
|
|
|
|
Standalone clustered operation mode is for when you want to run {{book.project.name}} within a cluster. This mode
|
|
requires that you have a copy of the {{book.project.name}} distribution on each machine you want to run a server instance.
|
|
This mode can be very easy to deploy initially, but can become quite cumbersome. To make a configuration change
|
|
you'll have to modify each distribution on each machine. For a large cluster this can become time consuming and error prone.
|
|
|
|
==== Standalone Clustered Configuration
|
|
|
|
The distribution has a mostly pre-configured app server configuration file for running within a cluster. It has all the specific
|
|
infrastructure settings for networking, databases, caches, and discovery. This file resides
|
|
in _.../standalone/configuration/standalone-ha.xml_. There's a few things missing from this configuration.
|
|
You can't run {{book.project.name}} in a cluster without a configuring a shared database connection. You also need to
|
|
deploy some type of load balancer in front of the cluster. The <<fake/../../clustering.adoc#_clustering,clustering>> and
|
|
<<fake/../../database.adoc#_database,database>> sections of this guide walk you though these things.

|
WARNING: 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 Clustered Boot Script
|
|
|
|
You use the same boot scripts to start {{book.project.name}} as you do in standalone mode. The difference is that
|
|
you pass in an additional flag to point to the HA config file.
