Default port numbers

The Open Liberty kernel and some Open Liberty features use default TCP/IP port numbers. You can override the default port numbers by specifying a different port number in your server configuration.

Runtime environment port numbers

The following table defines the default port numbers of Open Liberty features and provides examples of how you can override default ports in your server configuration.

FeatureDefault port and configuration example

Jakarta Enterprise Beans Remote

  • IIOP port: 2809

  • IIOP/SSL port: 9402

To modify the default port, specify the iiopPort attribute for the iiopEndpoint element and the iiopsPort attribute for the iiopsOptions subelement in your server.xml file, as shown in the following example:

<iiopEndpoint id="defaultIiopEndpoint" iiopPort="2809">
   <iiopsOptions iiopsPort="9402" sslRef="defaultSSLConfig"/>
</iiopEndpoint>

For more information, see iiopEndpoint.

Jakarta Servlet

  • HTTP port: 9080

  • HTTPS port: 9443

To modify the default ports, specify the httpPort or httpsPort attributes for the httpEndpoint element in your server.xml file, as shown in the following example:

<httpEndpoint id="defaultHttpEndpoint"
    httpPort="9082"
    httpsPort="9445" />

For more information, see HTTP Endpoint.

SIP Servlet

  • TCP port: 5060

  • TLS port: 5061

  • UDP port: 5060

To modify the default ports, specify the sipTCPPort,sipUDPPort, or sipTLSPort attributes for the sipEndpoint element in your server.xml file, as shown in the following example:

<sipEndpoint id="defaultSipEndpoint"
   sipTCPPort="5062"
   sipUDPPort="5062"
   sipTLSPort="5063" />

For more information, see sipEndpoint.

Message Server

  • Incoming unsecure port: 7276

  • Incoming secure port: 7286

To modify the default ports, specify the wasJmsPort or wasJmsSSLPort attributes for the wasJmsEndpoint element in your server.xml file, as shown in the following example:

<wasJmsEndpoint id="InboundJmsEndpoint"
   wasJmsPort="7278"
   wasJmsSSLPort="7288">
</wasJmsEndpoint>

For more information, WAS JMS Endpoint.

Liberty Kernel

For the command port, the Open Liberty server acquires a temporary port that is used by the command listener. You can configure this port in the bootstrap.properties file.

command.port=1

The default value for the command.port is 0.

For more information, see Set the command port.

For more information, see Server Configuration overview: bootstrap.properties.
