Clustering in domain mode

Continuing from the previous sections, we will see how to configure a cluster using domain mode. The same concepts apply to the domain mode, which means that to get clustering capabilities, we need to choose between the ha or full-ha profile.

As you already know, in domain mode, all the available and configured profiles reside in a single file, domain.xml. Each profile is then referenced by one or more server-groups.

To make it simple and clear, we belong to the default configuration and we will use the ha profile.

Server-group configuration

Before we begin, as usual, we will create a custom folder to run our JBoss in domain mode and we will define the necessry server-group.

We will first launch the application server with the --admin-only flag, so we can configure it without any running instances. We will then set all the configurations and restart the whole EAP with the --admin-only=false flag, which is normal-running.

Do as follows:

cd $JBOSS_HOME
cp -a domain master...
