[[_ports]]

=== Socket port bindings

The ports opened for each socket have a pre-defined default that can be overridden at the command line or within configuration.
To illustrate this configuration, let's pretend you are running in <<_standalone-mode,standalone mode>> and
open up the _.../standalone/configuration/standalone.xml_.  Search for `socket-binding-group`.

[source,xml]

    <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
        <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
        <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9993}"/>
        <socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
        <socket-binding name="http" port="${jboss.http.port:8080}"/>
        <socket-binding name="https" port="${jboss.https.port:8443}"/>
        <socket-binding name="txn-recovery-environment" port="4712"/>
        <socket-binding name="txn-status-manager" port="4713"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>

`socket-bindings` define socket connections that will be opened by the server.  These bindings specify the
`interface` (bind address) they use as well as what port number they will open.   The ones you will be most interested in are:

http::
   Defines the port used for {project_name} HTTP connections
https::
   Defines the port used for {project_name} HTTPS connections
ajp::
   This socket binding defines the port used for the AJP protocol.  This protocol is used by Apache HTTPD server
   in conjunction `mod-cluster` when you are using Apache HTTPD as a load balancer.
management-http::
   Defines the HTTP connection used by {appserver_name} CLI and web console.

When running in <<_domain-mode,domain mode>> setting the socket configurations
is a bit trickier as the example _domain.xml_ file has multiple `socket-binding-groups` defined.  If you scroll down
to the `server-group` definitions you can see what `socket-binding-group` is used for each `server-group`.

NOTE:  There are many more options available when setting up `socket-binding-group` definitions.  For more information, see link:{appserver_socket_link}[the socket binding group] in the _{appserver_socket_name}_.
