Firstly change to the installation directory used during the installation and ensure that the QPID_WORK environment variable is set.

Now use the qpid-server script to start the server:

bin/qpid-server

Output similar to the following will be seen:

[Broker] BRK-1006 : Using configuration : /var/qpidwork/config.json
[Broker] BRK-1001 : Startup : Version: 9.1.0 Build: exported
[Broker] BRK-1010 : Platform : JVM : Oracle Corporation version: 11.0.13+10-LTS-370 OS : Mac OS X version: 10.12.6 arch: x86_64 cores: 8
[Broker] BRK-1011 : Maximum Memory : Heap : 518,979,584 bytes Direct : 1,610,612,736 bytes
[Broker] BRK-1002 : Starting : Listening on TCP port 5672
[Broker] MNG-1001 : Web Management Startup
[Broker] MNG-1002 : Starting : HTTP : Listening on port 8080
[Broker] MNG-1004 : Web Management Ready
[Broker] BRK-1004 : Qpid Broker Ready

The BRK-1004 message confirms that the Broker is ready for work. The MNG-1002 and BRK-1002 confirm the ports on which the Broker is listening (for HTTP management and AMQP respectively).

To stop the Broker, use Control-C from the controlling shell, use the bin/qpid.stop script, use kill -TERM <pid>, or the REST operation broker/shutdown.
