How to install MQTT Broker on Raspberry Pi | IoT Server | Getting Started and Testing
In this video, I have explained how you can install MQTT Mosquitto Broker on Raspberry Pi. I have given a background on what is MQTT and tested it using Windows MQTTBox software
Hope you like it !!
*Installing Mosquitto Broker on Raspberry Pi*
1) Boot your Raspberry Pi, Open SSH terminal or VNC Viewer and Login into your RPI
2) Run the following command to upgrade and update your system
sudo apt update && sudo apt upgrade
It is always good to update and upgrade. This step will take time depending on what is installed and updated.
3) To install the Mosquitto Broker enter these next command
sudo apt install -y mosquitto mosquitto-clients
5) To make Mosquitto auto start when the Raspberry Pi boots, you need to run the following command
sudo systemctl enable mosquitto.service
This command will automatically start Mosquitto Broker on Raspberry Pi boot
6) To check the installation, run the following command to check the Mosquitto Broker version
mosquitto -v
This returns the Mosquitto version that is currently running on your Raspberry Pi
*Broker Enable Remote Access/ Authentication*
*****************************************************************
*No Authentication Process*
1) Edit the file mosquitto.conf
Go to the root directory of the file sudo nano /etc/mosquitto/mosquitto.conf
2) Add these lines at the end
allow_anonymous true #Allow any node to connect with the broker - without any authentication
listener 1883 #Defining the listener port
Save and Exit
3) Restart the Mosquitto Broker
sudo systemctl restart mosquitto
This will reflect the changes done the config file
********************************************************************
*Authentication Process*
1) Run the following command
sudo mosquitto_passwd -c /etc/mosquitto/PASSWORD USERNAME
This will allow you to add a new username by creating a folder in /etc/mosquitto directory.
As soon as you type it, it will ask you for the password that will be hidden
2) Edit the file mosquitto.conf
Go to the root directory of the file sudo nano /etc/mosquitto/mosquitto.conf
3) Add these lines at the end
allow_anonymous false #Allow specific nodes to connect with the broker - with authentication
listener 1883 #Defining the listener port
password_file /etc/mosquitto/PASSWORD
Save and Exit
3) Restart the Mosquitto Broker
sudo systemctl restart mosquitto
This will reflect the changes done to the config file
