Standalone Installation of HiveMQ on Windows Server 2022

Prerequisites

• Running Windows Environment e.g. HiveMQ Installation Guide - Windows Server 2022 on AWS

• Check Minimum system hardware requirements https://docs.hivemq.com/hivemq/latest/user-guide/system-requirements.html#minimum

• Install JRE (OpenJDK JRE 11 or newer is required.)

  • Download and Install JRE 11 or Later https://adoptium.net/en-GB/temurin/releases/?arch=x64&os=windows&package=jre&version=11. Please do note the Java version for the next step (11.0.22 in our case).

  • (Recommended) Set JAVA_HOME environment variable during installation can be done by enabling the following setting

    Open

    

  • (Manually) If you want to set JAVA_HOME environment variable manually, follow the steps:

    • Right-click on "This PC" and select "Properties".

    • Click on "Advanced system settings".

    • In the System Properties window, go to the "Advanced" tab and click on "Environment Variables".

    • Under "System Variables", click "New" and add a new variable:

      • Variable name: JAVA_HOME

      • Variable value: the path to your Java installation (e.g., C:\Program Files\Eclipse Adoptium\jdk-11.0.22.7-hotspot\).

      • C:\Program Files\Eclipse Adoptium\jdk-11.0.22.7-hotspot\bin exists under the path system variable list.

    • Click OK to close all dialogues.

Install HiveMQ

• Download and Extract HiveMQ:

  • First, you need to download the HiveMQ ZIP file from the official HiveMQ website. Download HiveMQ MQTT Platform | Trial Version Available | Try for Free

  • Unzip the folder to C:\ e.g. C:\hivemq-4.27.0

  • Rename this folder to hivemq so the path looks like C:\hivemq

  • Files inside the folder would have a structure e.g. C:\hivemq\bin

• Doing sanity checks

  • Setting Heap Size to 50% of system memory (4GB in this installation as RAM is 8 GB)

    • Go to C:\hivemq\bin

    • Open the run.bat file with Notepad or any other editor

    • Search for the VARIABLES section

    • The following code example sets the heap size to the recommended 50% of the available RAM:
      set "JAVA_OPTS=%JAVA_OPTS% -XX:+UnlockExperimentalVMOptions -XX:InitialRAMPercentage=40 -XX:MaxRAMPercentage=50 -XX:MinRAMPercentage=30"
      
      

      Open

      

    • Save the file

• Run HiveMQ broker

  • Go to C:\hivemq\bin

  • Right-click on the file “run.bat” and run it as an administrator

  • This should start the HiveMQ process as shown below

End to End connection testing with MQTT CLI

• Please make sure HiveMQ Broker is running

• Please make sure that port 1883 is enabled (e.g. inbound rules under security groups)
  
  

• Setup MQTT CLI

  • Download MQTT CLI

    • Go to the release link https://github.com/hivemq/mqtt-cli and go to the latest release.

• Download the correct zip for Windows (mqtt-cli-4.27.0-win.zip in our case)

  • Extract the zip file

  • Open the command prompt and CD into the MQTT CLI folder, this folder contains mqtt-cli.exe which will be used for the next steps.
    
    

• Subscribe to a Topic: Subscribe to a topic using MQTT CLI with the command:

  mqtt-cli.exe sub -h localhost -p 1883 -i MQTTCLIClientSUB -t "connection/test"

  This command subscribes to the topic connection/test on the broker running on localhost.
  
  

• Publish to the Same Topic: Open another command prompt window, CD to the MQTT CLI folder, and publish a message to the same topic with:

  mqtt-cli.exe pub -h localhost -p 1883 -i MQTTCLIClientPUB -t "connection/test" -m "Test MQTT CLI"

  This publishes the message "Test MQTT CLI" to the connection/test topic.
  
  

• Verify Message Receipt: Check the first command prompt window where you subscribed to the topic. You should see the message "Test MQTT CLI" appear, indicating that the message was successfully published and received.
