To start a single HiveMQ instance and allow access to the MQTT port as well as the Control Center, get Docker and run the following command:
docker run --ulimit nofile=500000:500000 -p 8080:8080 -p 8000:8000 -p 1883:1883 hivemq/hivemq4
You can connect to the broker via MQTT (1883) or Websockets (8000) or the Control Center (8080) via the respective ports.
For clustering and configuration please refer to the readme.
