HiveMQ on Amazon Web Services (AWS)

There are several ways to deploy HiveMQ on Amazon Web Service (AWS). The following procedure shows you how to easily deploy HiveMQ on an AWS EC2 instance:

Quick-Launch HiveMQ on an AWS EC2 instance

HiveMQ pre-built Amazon Machine Images (AMI) help you deploy a HiveMQ instance on AWS EC2 with ease.
The following procedure sets up a fully operational HiveMQ AWS EC2 instance on your AWS account.

Requirements

  • Amazon Web Services Account

  • HiveMQ License (optional)

If you do not have a valid HiveMQ license, the HiveMQ cluster uses a trial licence that allows up to 25 concurrent client connections and is limited to testing and evaluation purposes only. To obtain a HiveMQ license that is suitable for production use, or request an evaluation license that allows more connections, contact our customer service team.

Select Your AMI

The AWS region you choose determines the HiveMQ AMI to use for your installation.

HiveMQ currently maintains AMI for 17 regions.
All HiveMQ AMIs are available from the official HiveMQ website. After you log into your AWS account, open the HiveMQ and AWS page of the HiveMQ website and select an AMI from the Choose AMI list.
On the HiveMQ website, you can use the Load more option to browse through available HiveMQ AMIs.

After you select an AMI, the AWS console to configure and launch an EC2 instance opens:

AWS Launch Instance

Names and Tags

To make it easier to identify the launched instance on your AWS web console, enter a name for your instance in the Name and tags area.

AWS Name and Tags

Optional tags are useful for adding metadata to your instance. To learn more about tags, select Info in the Names and tags header.

To create further tags, select the Add additional tags option.

Application and OS Images (Amazon Machine Image)

Verify that a HiveMQ AMI entry similar to the following example is selected to launch your instance.

Once the HiveMQ MQTT broker is running, you can use any MQTT client to connect to your HiveMQ MQTT broker on port 1883.

Build an Elastic High-Availability HiveMQ Cluster on AWS EC2

HiveMQ is a cloud-native MQTT broker that offers superior elastic clustering capabilities and a resilient software design that make it a perfect fit for common cloud infrastructures. When you run HiveMQ in production, the use of cloud infrastructure such as AWS ensures that elastic scalability and adequate security standards are in place on the infrastructure side.

Requirements

  • Amazon Web Services Account

  • HiveMQ License (optional)

If you do not have a valid HiveMQ license, the HiveMQ cluster uses a trial licence that allows up to 25 concurrent client connections and is limited to testing and evaluation purposes only. To obtain a HiveMQ licence that is suitable for production use, or request an evaluation licence that allows more connections, contact our customer service team.

Procedure

The use of Amazon Simple Storage Service (S3) buckets for auto-discovery is a perfect alternative when the individual HiveMQ broker nodes run on AWS EC2 instances. To simplify installation, HiveMQ offers a free pre-built extension for AWS S3 cluster discovery.

The following procedure shows you how to set up a HiveMQ cluster on AWS EC2 instances that use Amazon S3 buckets for automatic cluster discovery.

Create a Security Group

To allow inbound traffic to the listeners that you configure for MQTT communication in the following steps, you need to set up a security group. After you create the security group, you can edit the group and add a rule for the internal communication between cluster nodes on all TCP ports that uses the security group as the source. It is also essential to have SSH access on the instances.

AWS Sign In
  • On the EC2 Dashboard, go to Network & Security | Security Groups, and select Create security group:

Install and Configure HiveMQ S3 Cluster Discovery Extension

In the following steps, you enable the cluster mode on both of our HiveMQ instances and provide a way for the instances to discover each other with the HiveMQ S3 Cluster Discovery Extension:

  • Create an S3 Bucket that your HiveMQ instances can use, and make sure to remember the bucket name. You can use the default configuration at this time.

  • Repeat the following steps individually for each of your HiveMQ instances:

    • Connect to the HiveMQ instance via SSH:

ssh -i <your-deployment-key> ec2-user@<instance-ip-address>
  • Switch to the root user:

sudo su
  • Download the latest version of the HiveMQ S3 Cluster Discovery Extension:

wget https://www.hivemq.com/releases/extensions/hivemq-s3-cluster-discovery-extension-4.2.0.zip
  • Unzip the distribution in the extensions folder of the HiveMQ installation (this action creates a hivemq-s3-cluster-discovery-extension folder):

unzip hivemq-s3-cluster-discovery-extension-4.2.0.zip
  • Open the HiveMQ S3 Cluster Discovery Extension configuration file (if desired, use a different text editor):

vi hivemq-s3-cluster-discovery-extension/hivemq-s3-cluster-discovery-extension.xml
  • Configure the S3 Bucket region and name:

############################################################
# S3 Bucket                                                #
############################################################

#
# Region for the S3 bucket used by hivemq
# see http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region for a list of regions for S3
# example: us-west-2
#
s3-bucket-region:<your-region>

#
# Name of the bucket used by HiveMQ
#
s3-bucket-name:<your-bucket-name>
  • To complete the installation of the S3 cluster discovery extension, move the folder of the extension to the HiveMQ extensions folder:

mv hivemq-s3-cluster-discovery-extension/ /opt/hivemq/extensions/
  • Change ownership of the extension folder to the hivemq user:

chown -R hivmq:hivemq hivemq-s3-cluster-discovery-extension
  • Adjust the HiveMQ /opt/hivemq/conf/config.xml configuration file as follows and enter the internal IP address of your EC2 instance as the bind address for TCP transport:

<?xml version="1.0"?>
<hivemq>

    <listeners>
        <tcp-listener>
            <port>1883</port>
            <bind-address>0.0.0.0</bind-address>
        </tcp-listener>
    </listeners>

    <cluster>
        <enabled>true</enabled>
        <transport>
            <tcp>
                <!--enter IP address of your EC2 instance-->
                <bind-address>IP_ADDRESS</bind-address>
                <bind-port>7800</bind-port>
            </tcp>
        </transport>

        <discovery>
            <extension/>
        </discovery>
    </cluster>

    <anonymous-usage-statistics>
        <enabled>true</enabled>
    </anonymous-usage-statistics>

    <control-center>
        <listeners>
            <http>
                <port>8080</port>
                <bind-address>0.0.0.0</bind-address>
            </http>
        </listeners>
    </control-center>
</hivemq>
  • Restart HiveMQ on both EC2 instances:

/etc/init.d/hivemq restart
  • Check the log statement in the /opt/hivemq/log/hivemq.log file. A statement similar to the following shows that the cluster is successfully established:

INFO - Cluster size = 2, members : [8Jojp, WlF1S]

Repeat the previous steps to create a HiveMQ cluster with the desired number of nodes.

Launch and Configure an AWS Network Load Balancer (NLB)

Add a load balancer to your setup that allows your HiveMQ broker cluster to act as a single logical broker node for all connecting MQTT clients. The MQTT client only needs to know the load-balancer URL to connect, publish, and subscribe.

  • On your AWS EC2 Dashboard, go to Load Balancing | Target Groups and select Create target group:

Target Group
  • on the Specify group details page, configure the following:

    • Select Instances as the target type.

    • Enter your desired Target group name.

    • Select TCP for the Protocol and enter 1883 for the Port.

    • Select the VPC with the HiveMQ instances that you want to include in the target group.

    • Select TCP as the Health check protocol. _

  • Select Next to review your configuration, then select Create target group_.

  • In the confirmation window that opens, select your newly created target group, and select Register targets:

Register Targets
  • Select your HiveMQ instances from the list of Available instances to add the instances to the list of pending targets. Select Register pending targets to register the targets:

Register Pending Targets
  • Return to your AWS EC2 Dashboard and go to Load Balancing | Load Balancers | Create Load Balancer:

Create Load Balancer
  • From the available load balancer options, select Network Load Balancer TCP, TLS, UDP:

Select Load Balancer
  • On the Create Network Load Balancer page, configure your load balancer as follows:

    • Enter a load balancer name.

    • Select the Internet-facing scheme.

    • Select IPv4 for the IP address type.

    • In Networking mapping, configure your VPC and availability zones according to your needs. Best practise is to choose all availability zones.

    • In Listeners and routing, select TCP as the Protocol of the listener, enter 1883 as the Port, and your target group as the Default action.

  • Select Create load balancer to create a network load balancer with the selected configuration:

Create Balancer

Once the load balancer finishes provisioning, clients can connect to your HiveMQ cluster with the DNS name of the load balancer.

For production environments, best practice is to use automatic provisioning of the EC2 instances that eliminates the need to configure each EC2 instance manually. For example, tools such as Chef, Puppet, or Ansible.

It is also possible to use Docker to simplify the provisioning of HiveMQ nodes. For more information, see HiveMQ with Docker

Deploy HiveMQ with Amazon Elastic Kubernetes Service (EKS) and the HiveMQ Platform Operator for Kubernetes

HiveMQ on Microsoft Azure

There are several ways to deploy HiveMQ on Azure. The following procedures walk you through how to deploy a HiveMQ cluster on Azure with an ARM quickstart template or with Azure Kubernetes Service (AKS).

Quick-Launch HiveMQ Virtual Machine Cluster on Azure with HiveMQ ARM Quickstart Template

The arm-quickstart-templates folder that is included in the hivemq-azure-cluster-discovery-extension contains a hivemq-vm-cluster ARM template that lets you quickly deploy one or more HiveMQ instances on Microsoft Azure.

The following installation sets up a fully operational HiveMQ virtual machine cluster on your Azure account with the sizing of your choice.

HiveMQ ARM Quickstart Templates

Azure Resource Manager is the deployment and management service for Azure. A resource manager template is a JSON file that defines one or more resources to deploy to a resource group, subscription, management group, or tenant. The template can be used to deploy resources consistently and repeatedly.

The HiveMQ Virtual Machines Cluster ARM template deploys a cluster of HiveMQ virtual machines to Azure with the number of HiveMQ instances you select. Each HiveMQ instance (node) is one virtual machine. The HiveMQ Azure Cluster Discovery Extension that the template installs on each node enables the HiveMQ cluster nodes to discover each other dynamically through the regular exchange of information via Azure blobs in an Azure blob-storage container.

The hivemq-vm-cluster ARM quickstart template automates deployment of the following resources to Azure:

  • One or more virtual machines preinstalled with HiveMQ and the HiveMQ Azure Cluster Discovery Extension

  • An Azure Storage Account for the extension to use

  • An Azure Availability Set in which the virtual machines are located

  • An Azure load balancer to access the HiveMQ services

  • A virtual network in which the virtual machines and load balancer are located

  • Network interfaces with public IP addresses for the virtual machines

  • A network interface with a public IP-Address for the load balancer

Requirements

  • Microsoft Azure account

  • GitHub account

  • HiveMQ License (optional)

If you do not have a valid HiveMQ license, the HiveMQ cluster uses a trial licence that allows up to 25 concurrent client connections and is limited to testing and evaluation purposes only. To obtain a HiveMQ licence that is suitable for production use, or request an evaluation licence that allows more connections, contact our customer service team.

Deploy Your HiveMQ Cluster with an ARM Quickstart Template

Before you get started, make sure that you have the sign-in information for your Microsoft account available.
Deploy to Azure
  • A window to sign in to your Microsoft account opens:

Microsoft Azure Sign In
  • After you sign in to your Microsoft account, a page to edit the customized template you are about to deploy opens:

  • To save your changes and open a validation window, select Review + Create:

Validation
  • To confirm the template configuration and continue with the deployment, review the Azure terms of service and select Create.

Your Microsoft Azure account bills you for all resources you create. When you delete a template deployment, the resources you created are not affected. To remove resources, you must delete the resource group. Deletion of a resource group permanently deletes all resources in the resource group and cannot be undone.
  • An overview window opens and shows the progress of your deployment:

Progress
  • To view progress information for each resource in the deployment as it is added, expand the Deployment details section.

The azuredeploy.json file of the hivemq-vm-cluster ARM template lists the parameter and variable configurations that the resource deploys.
  • Once your deployment is complete, a deployment overview for your template opens:

Deployment Complete
Since version 4.3, HiveMQ only allows MQTT clients to connect if a security extension is present. For testing purposes, HiveMQ includes a hivemq-allow-all-extension that authorizes all MQTT clients to connect to HiveMQ. Before you use HiveMQ in production, you must add an appropriate security extension and remove the hivemq-allow-all-extension. You can download security extensions from the HiveMQ website or develop your own security extension.
  • If you have a valid HiveMQ license, install the license information on each HiveMQ node in your cluster.
    For more information, see Install a HiveMQ License. Skip this step if you are using a HiveMQ trial license.

  • To verify that your HiveMQ cluster is running, check to see whether your HiveMQ Control Center is accessible:

When you see the login dialog for the HiveMQ Control Center, you know that HiveMQ is up and running.

  • The HiveMQ Control Center is part of the standard HiveMQ distribution and is a web application that you can access from your browser for quick insights into your HiveMQ cluster.

By default, the HiveMQ broker starts on localhost IP address (127.0.0.1) and listens on port 1883.

You do not need to install any additional software on your computer to use the control center. The default login credentials are: user: admin, password: hivemq. For more information, see HiveMQ Control Center.

HiveMQ Control Center login dialog
When you no longer need your HiveMQ cluster on Azure, be sure to delete the Azure resource group that you created. Deletion of an Azure resource group permanently removes the resource group and all associated resources. This action can not be undone. Deletion of an Azure deployment does not affect the Azure resource group or the associated resources.

Deploy HiveMQ with Azure Kubernetes Service (AKS) and the HiveMQ Platform Operator for Kubernetes

brew install hivemq/mqtt-cli/mqtt-cli

For other operating systems, see MQTT-CLI installation.

Set Up Your Kubernetes Cluster With AKS

To create a Kubernetes cluster on Azure with the Azure CLI, open a terminal and enter:

az login

A window to sign in to your Microsoft account opens in your browser:

Microsoft Azure Sign In

After you successfully submit your credentials, a sign-in confirmation prints in your terminal.

Before you create the cluster, you need to select the region where the cluster is hosted. To view a list of all available locations, enter:

az account list-locations
Excerpt of Azure locations JSON
  ...

  },
  {
    "displayName": "Germany North",
    "id": "/subscriptions/661ab844-9998-4e03-b857-62ecbd9f34e8/locations/germanynorth",
    "metadata": {
      "geographyGroup": "Europe",
      "latitude": "53.073635",
      "longitude": "8.806422",
      "pairedRegion": [
        {
          "id": "/subscriptions/661ab844-9998-4e03-b857-62ecbd9f34e8/locations/germanywestcentral",
          "name": "germanywestcentral",
          "subscriptionId": null
        }
      ],
      "physicalLocation": "Berlin",
      "regionCategory": "Other",
      "regionType": "Physical"
    },
    "name": "germanynorth",
    "regionalDisplayName": "(Europe) Germany North",
    "subscriptionId": null
  },
...

To create an Azure Resource Group with all the necessary resources for your cluster, enter the following command with the desired location (in this procedure, we use germanywestcentral):

az group create --name hmqResourceGroup --location germanywestcentral

To create a four-node AKS-managed Kubernetes cluster in your resource group with the Azure virtual machine type Standard_A8_v2 (8 CPUs, 16 GiB RAM), enter the following command and wait until the process completes.
Processing time can vary:

az aks create -g hmqResourceGroup -n HiveMQCluster --node-count 4 --node-vm-size Standard_A8_v2
Your Microsoft Azure account bills you for all resources you create.

To manage the resulting Kubernetes cluster with kubectl, download the access credentials of the cluster:

az aks get-credentials -g hmqResourceGroup -n HiveMQCluster

To verify that all four nodes are available, enter:

kubectl get nodes

The output from the command is similar to the following:

NAME                                STATUS   ROLES   AGE     VERSION
aks-nodepool1-37471664-vmss000000   Ready    agent   5m44s   v1.18.10
aks-nodepool1-37471664-vmss000001   Ready    agent   5m50s   v1.18.10
aks-nodepool1-37471664-vmss000002   Ready    agent   5m47s   v1.18.10
aks-nodepool1-37471664-vmss000003   Ready    agent   5m47s   v1.18.10

Add A License To Your HiveMQ Cluster (skip this step if you are using a HiveMQ trial license)

If you do not have a valid HiveMQ license, the HiveMQ cluster uses a trial licence that allows up to 25 concurrent client connections and is limited to testing and evaluation purposes only. To obtain a HiveMQ licence that is suitable for production use, or request an evaluation licence that allows more connections, contact our customer service team.

If you have a valid HiveMQ license, create a hivemq-license Kubernetes ConfigMap from your licence file to make the licence information accessible for the HiveMQ deployment you execute in the next step:

kubectl create configmap hivemq-license --from-file=hivemq-license.lic

Install HiveMQ Platform Operator for Kubernetes and Deploy HiveMQ on Your AKS Cluster

The HiveMQ Platform Operator for Kubernetes is a tool for managing your HiveMQ deployments in a Kubernetes environment. The operator makes it easy to install, scale, configure, and monitor your HiveMQ Platform deployments in a versatile, adaptable manner.

Follow our HiveMQ Platform Operator for Kubernetes Quick Start Guide to use the Helm package manager for Kubernetes to bootstrap the deployment and management of your HiveMQ Platform.

The HiveMQ Platform Operator for Kubernetes simplifies HiveMQ deployment and management on AKS.

For step-by-step instructions on how to use the operator to install HiveMQ on AKS, see Installation on Azure Kubernetes Service in the Kubernetes distributions section of the HiveMQ Platform Operator for Kubernetes documentation.

Connect To Your HiveMQ Cluster

Once your HiveMQ cluster is up and running, you are ready to connect clients to the cluster with the MQTT-CLI.
To obtain the exposed ENDPOINT of the created load balancer on which clients connect to your cluster, enter:

kubectl get hivemq-clusters

Output similar to the following displays:

$ kubectl get hivemq-clusters
NAME     SIZE   IMAGE            VERSION     STATUS    ENDPOINT       MESSAGE
hivemq   3      hivemq/hivemq4   k8s-4.4.3   Running   20.52.209.35   Live updates completed successfully

To start up the MQTT-CLI in shell mode, enter:

mqtt sh

In shell-mode, connect a new MQTT client to your HiveMQ cluster on the previously acquired endpoint address:

con -h 20.52.209.35

You have now successfully connected a new MQTT client to a HiveMQ cluster hosted on Azure.
To learn more ways to interact with HiveMQ, see the MQTT-CLI documentation.

Monitor Your HiveMQ Cluster

Monitoring your MQTT brokers is vital, especially in clustered environments. The highly-performant metrics subsystem of HiveMQ lets you monitor relevant metrics with no reduction in system performance.

HiveMQ Control Center

The HiveMQ Control Center provides a quick and convenient way to get insights into your HiveMQ cluster.
To access your HiveMQ Control Center, forward the port of the control center to our local machine:

kubectl port-forward svc/hivemq-hivemq-cc 8080:8080

This command blocks the console and makes the HiveMQ Control Center available on http://localhost:8080.
You do not need to install any additional software on your computer to use the control center.
To login, enter the default login credentials: user: admin, password: hivemq.

HiveMQ Control Center login dialog

The dashboard of your HiveMQ Control Center opens:

HiveMQ Control Center dashboard

Tear Down Your Azure Kubernetes Service Cluster

To delete everything that you just created, use the Azure CLI to delete your entire Azure resource group:

az aks delete -g hmqResourceGroup -n HiveMQCluster
This action permanently deletes the Azure resource group and all related resources. This action can not be undone.
