Standard System Properties
jboss.qualified.host.name
Relevance: WildFly 9
For a host named "ap1.modcluster.local" it is set to "ap1.modcluster.local"
The value of the first segment of this system property will override the <host> element name attribute in host.xml. For more details see host.xml <host> name.
jboss.host.name
Relevance: WildFly 9
For a host named "ap1.modcluster.local" it is set to "ap1".
The value of this system property will override the <host> element name attribute in host.xml. For more details see host.xml <host> name.
jboss.server.name
Relevance: WildFly 9
For a host named "ap1.modcluster.local" it is set to "ap1"
jboss.node.name
Relevance: WildFly 9
Set externally with -Djboss.node.name in the startup script.

- 'jboss.node.name' and the JBoss startup script

jboss.server.config.dir
Used by:
jboss.bind.address
Represents the value of the instance's public interface. The default value is 127.0.0.1.
jboss.bind.address for Standalone Node
One common method of externalizing this operationally is to define it as a system property at the bottom of $JBOSS_HOME/bin/standalone.conf:
...
JAVA_HOME="${JAVA_HOME} -Djboss.bind.address=192.168.1.15"
The same result can be achieved by specifying the system property as a -D argument for the start script:
./standalone.sh -Djboss.bind.address=192.168.1.10
jboss.bind.address for Host Controller
One common method to externalize the value operationally for host controllers is to define it as a system property at the bottom of $JBOSS_HOME/bin/domain.conf as follows:
...
HOST_CONTROLLER_JAVA_OPTS="${HOST_CONTROLLER_JAVA_OPTS} -Djboss.bind.address=1.2.3.4"
The value propagates as system property to the process controller, host controller and servers:
eap 13556 13457 java -D[Process Controller] ... -Djboss.bind.address=1.2.3.4 ... eap 13595 13556 java -D[Host Controller] ... -Djboss.bind.address=1.2.3.4 ... eap 13750 13556 /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.79.x86_64/jre/bin/java -D[Server:ri2] ... -Djboss.bind.address=1.2.3.4 ...
In consequence, servers bind their HTTP connectors to that address.
jboss.bind.address.management
The value of the instance's management interface bind address. The default value is 127.0.0.1.
jboss.bind.address.management for Standalone Node
One common method of externalizing this operationally is to define it as a system property at the bottom of $JBOSS_HOME/bin/standalone.conf:
...
JAVA_HOME="${JAVA_HOME} -Djboss.bind.address.management=192.168.1.15"
The same result can be achieved by specifying the system property as a -D argument for the start script:
./standalone.sh -Djboss.bind.address.management=192.168.1.10
jboss.bind.address.management for Host and Domain Controller
One common method to externalize the value operationally for host and domain controllers is to define it as a system property at the bottom of $JBOSS_HOME/bin/domain.conf as follows:
...
HOST_CONTROLLER_JAVA_OPTS="${HOST_CONTROLLER_JAVA_OPTS} -Djboss.bind.address.management=1.2.3.4"
jboss.bind.address.unsecure
The value to bind the "unsecure" interface to. By default 127.0.0.1.
jboss.domain.master.address
The hostname of the domain controller.
It is actually not a good idea to externalize the master domain controller address as a system property. For more explanations see:
jboss.domain.master.port
The port of the domain controller process.
