Bind Addresses

By default {project_name} binds to the localhost loopback address 127.0.0.1. That’s not a very useful default if you want the authentication server available on your network. Generally, what we recommend is that you deploy a reverse proxy or load balancer on a public network and route traffic to individual {project_name} server instances on a private network. In either case though, you still need to set up your network interfaces to bind to something other than localhost.

Setting the bind address is quite easy and can be done on the command line with either the standalone.sh or domain.sh boot scripts discussed in the Choosing an Operating Mode chapter.

$ standalone.sh -b 192.168.0.5

The -b switch sets the IP bind address for any public interfaces.

Alternatively, if you don’t want to set the bind address at the command line, you can edit the profile configuration of your deployment. Open up the profile configuration file (standalone.xml or domain.xml depending on your operating mode) and look for the interfaces XML block.

    <interfaces>
        <interface name="management">
            <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
        </interface>
        <interface name="public">
            <inet-address value="${jboss.bind.address:127.0.0.1}"/>
        </interface>
    </interfaces>

The public interface corresponds to subsystems creating sockets that are available publicly. An example of one of these subsystems is the web layer which serves up the authentication endpoints of {project_name}. The management interface corresponds to sockets opened up by the management layer of the {appserver_name}. Specifically the sockets which allow you to use the jboss-cli.sh command line interface and the {appserver_name} web console.

In looking at the public interface you see that it has a special string ${jboss.bind.address:127.0.0.1}. This string denotes a value 127.0.0.1 that can be overridden on the command line by setting a Java system property, i.e.:

$ domain.sh -Djboss.bind.address=192.168.0.5

The -b is just a shorthand notation for this command. So, you can either change the bind address value directly in the profile config, or change it on the command line when you boot up.

Note
There are many more options available when setting up interface definitions. For more information, see the network interface in the {appserver_network_name}.
