You may get the warning “WFLYTX0013: Node identifier property is set to the default value. Please make sure it is unique.” in your logs when you startup WildFly even if you are running in standalone mode. This really isn’t a problem but if you want to prevent this from showing up in your logs edit your standalone-full.xml (or the standalone config file you are using) by adding an identifier to the appropriate tag.
Find the tag <core-environment> and change it to:
Or, whatever you like. (Maybe the actually host name?)
But, keep in mind if your environment/application grows where you need multiple nodes THIS MUST BE A UNIQUE VALUE on each of your wildfly nodes so you will have to update/change this value as you add nodes.
