=== Standalone Clustered
|
|
|
|
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 each distribution for each node you want to run in the cluster. While very easy to
|
|
deploy initially, this mode can become cumbersome if you end up having a large cluster because you will have to
|
|
modify the configuration in each node anytime you need to make a change.
|
|
|
|
==== Standalone Clustered Configuration
|
|
|
|
The distribution has a pre-configured app server configuration file for running within a cluster. It has all the specific
|
|
infrasture settings you need for the clustered caches and discovery that {{book.project.name}} needs. This file resides
|
|
in _.../standalone/configuration/standalone-ha.xml_
|
|
|
|
.Standalone HA Config

|
|
|
|
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 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.
|
|
|
|
.Standalone Clustered Boot Scripts
|
|
image:../../{{book.images}}/standalone-boot-files.png[]
|
|
|
|
To boot the server:
|
|
|
|
.Linux/Unix
|
|
[source]
|
|
----
|
|
$ .../bin/standalone.sh --server-config=standalone-ha.xml
|
|
----
|
|
|
|
.Windows
|
|
[source]
|
|
----
|
|
> ...\bin\standalone.bat --server-config=standalone-ha.xml
|
|
----
|
|
|
|
==== Standalone Clustered{{book.project.name}} Configuration
|
|
|
|
The {{book.project.name}} specific json configure file resides in the same place as in standalone mode: _.../standalone/configuration/keycloak.json_.
|
|
Like _standalone-ha.xml_ you have to modify this file in each distribution in your cluster in order for changes to take effect.
|
|
|
|
NOTE: Any changes you make to this file while the server is running will not take effect. You'll need to reboot the
|
|
server.
