Installation

Prerequisites

At least Java 8 is required to run MQTT CLI.

The CLI is implemented with Java 11 which is the preferred version to run this project.

Docker

You can run MQTT-CLI on every OS which supports Docker. To execute a simple command use the following syntax:

docker run hivemq/mqtt-cli <your-command>

To start the Shell-Mode of the CLI you need to add the -it flags to the docker-command:

docker run -it hivemq/mqtt-cli shell

Homebrew

For Mac OS X and Linux systems use Homebrew to install MQTT CLI via the MQTT CLI Tap.

brew install hivemq/mqtt-cli/mqtt-cli

NOTE: If you encounter an error like Java 1.8+ is required to install this formula please install a java version higher than 1.8. You can use brew install --cask zulu to install the latest release of Azul Zulu OpenJDK.

NOTE: As latency-issues may slow down the CLI under Mac OS X please verify that you have the entry 127.0.0.1 localhost your-pc-name specified under /etc/hosts. You can use sudo sh -c "echo 127.0.0.1 localhost $(hostname) >> /etc/hosts" to append this configuration to your hosts file.

Windows Zip

Download the Windows Zipfile and extract it in your preferred location. To execute MQTT CLI simply open the Windows Command Prompt with ⊞ Win + R and execute cmd. Navigate into the extracted MQTT CLI folder and execute mqtt-cli.exe.

To quick start the shell simply double-click the mqtt-cli-shell.cmd file.

Debian Package

If you are using a *nix operating system which operates with debian packages you can download the MQTT CLI debian package from the releases page via wget or curl and install the package with sudo dpkg -i or sudo apt install:

wget https://github.com/hivemq/mqtt-cli/releases/download/v4.32.0/mqtt-cli-4.32.0.deb
sudo apt install ./mqtt-cli-4.32.0.deb

RPM Package

For Red Hat, Fedora, Mandriva, OpenSuse, CentOS distributions you can use the rpm package provided at releases page. The preferred way is to install the package via the yum package manager. To install the package simply execute:

sudo yum install -y https://github.com/hivemq/mqtt-cli/releases/download/v4.32.0/mqtt-cli-4.32.0.rpm

Building From Source

• mqtt-cli uses Gradle to build.
• To be able to execute integration tests a running Docker environment is required
• To be able to build and test the native image a GraalVM installation is required. You can set it up with ./gradlew installNativeImageTooling.

To do a clean build, issue the following command: ./gradlew clean build

This runs the unit tests and compiles a new mqtt-cli-.jar into build/libs. You can then update an existing MQTT CLI installation by replacing its mqtt-cli-.jar with this one.

The build.gradle.kts file contains further instructions for building the platform specific distribution packages. In a nutshell:

For MacOS/Linux brew: ./gradlew buildBrewFormula

For the Debian package: ./gradlew buildDebianPackage

For the RPM package: ./gradlew buildRpmPackage

For the Windows installer: ./gradlew buildWindowsZip

For building a local docker image: ./gradlew jibDockerBuild
