How to Install Mosquitto Broker on Raspberry Pi

In this post you’re going to How to Install Mosquitto Broker on Raspberry Pi.

After having your Raspberry Pi board prepared with Raspbian OS, you can continue with this tutorial. Let’s install the Mosquitto Broker.

How to Install Mosquitto Broker on Raspberry Pi (Raspbian OS)

Open a new Raspberry Pi terminal window:

To install the Mosquitto Broker enter these next commands:

pi@raspberry:~ $ sudo apt update
pi@raspberry:~ $ sudo apt install -y mosquitto mosquitto-clients

You’ll have to type Y and press Enter to confirm the installation. To make Mosquitto auto start on boot up enter:

pi@raspberry:~ $ sudo systemctl enable mosquitto.service

Testing Installation

Open terminal and write command:

pi@raspberry:~ $ mosquitto -v

This returns the Mosquitto version that is currently running in your Raspberry Pi.

Note: sometimes the command mosquitto -v prompts a warning message saying “Error: Address already in use“. That warning message means that your Mosquitto Broker is already running, so don’t worry about that.

How To Find IP Address

To use Mosquitto broker later on your projects, you’ll need your Raspberry Pi IP address. To retrieve your Raspberry Pi IP address, type the next command in your Terminal window:

pi@raspberry:~ $ hostname -I

In our case, the Raspberry Pi IP address is 192.168.1.121. Save your Raspberry Pi IP address because you’ll need it in future projects.
