Setting up the MQTT broker

Remember the old boring update process of vision processing? How can you forget? We have to do the same here as well. But lucky for us, this time it's not very long. So, let's see what we have to do to set up this server. Open up your command line and type in these following lines:

sudo apt-get update
sudo apt-get upgrade

You know what this line does. If you don't have a clear memory of it, then refer to Chapter 9, Vision Processing. Once the update and upgrade processes are complete, go ahead and install the following packages:

sudo apt-get install mosquitto -y

This will install the Mosquitto broker onto your Raspberry Pi. This broker will take care of all the data transfer:

sudo apt-get install mosquitto-clients -y

Now, this line will install the client packages. As you can imagine, Raspberry Pi in itself will be a client to the broker. Hence, it will take care of the needful.

We have now installed the packages; yes exactly, it was that small. Now, all we need to do...
