With this tutorial, we will be showing you the process of installing the UniFi Controller on a Raspberry Pi
UniFi is a range of network devices created by Ubiquiti. These devices range from Wi-Fi access points to security gateways and switches.
Setting up the UniFi software on a Raspberry Pi is a fairly straightforward process as it just relies on the multi-platform Java runtime to run.
Using the UniFi network controller, you can manage all the UniFi devices that are a part of your network. You will also be able to use this dashboard to see the statistics of your UniFi network.
Please note that before proceeding you will need to be running a 32-bit version of Raspberry Pi OS for this tutorial to work. At this time, 64-bit is not supported.
Below is a list of the equipment that you will need to set up the Unifi Network Controller software on your Raspberry Pi
Preparing your Raspberry Pi for the UniFi Controller
In this section, we will be preparing the operating system so it can run the UniFi software.
1. The first thing you should do is ensure that your Raspberry Pi is running up to date packages.
To update all packages, you will be required to run the following command.
sudo apt update sudo apt upgrade
2. To improve the startup speed of the UniFi controller software on our Raspberry Pi, we need to install
We will utilize this package to ensure the Raspberry Pi has enough entropy for the random number generation that the UniFi software uses.
sudo apt install rng-tools
3. We now need to make a slight change to the rng-tools configuration.
Begin editing the config file by running the following command.
sudo nano /etc/default/rng-tools-debian
4. Within this file, find and uncomment the following line.
By uncommenting this line, we are adding to the amount of entropy (The amount of randomness) that the system has available.
The Raspberry Pi features an integrated random number generator that we can utilize to increase the entropy pool.
5. Once you have made the change, save the file by pressing CTRL + X, then Y, followed by ENTER.
6. Finally, restart the
rng-tools service by running the command below.
sudo systemctl restart rng-tools
Once the service has finished restarting, it should now be safe to proceed to the next section of this guide.
Extra Steps for Raspberry Pi OS Bullseye
When trying to install the UniFi controller on Raspberry Pi OS Bullseye, you will run into issues with the
mongodb package not being available.
To work around this issue we can add the old stretch repository as a source and pin it so that none of its packages will take preference.
mongodb will be made available from the official repository, but for now, we will have to work around it
1. Let us start by creating a preferences file for the apt package manager. This file will allow us to modify the priority of the repository that we are about to add.
You can start writing this preferences file by using the following command.
sudo nano /etc/apt/preferences.d/99stretch-mongodb.pref
2. Within this file, you will need to type in the following lines.
#Never Prefer packages from Stretch Package: * Pin: release n=stretch Pin-Priority: 1
These lines tell the apt package manager a few different things. First, we use the wildcard for our package name. The wildcard means our following rules will apply to all packages available.
The following two lines are what we use to set a priority for packages from our new repository. By setting the “
1, we ensure that apt will prefer other packages over ones from the Stretch repository.
3. Once you have made these changes to the file, you can save and quit by pressing CTRL + X, then Y, followed by the ENTER key.
4. Now that we have created our new preferences file, we can now add our repository that contains
Before we can add this repository, we will first need to download the GPG key for the Raspbian repository. This key helps authenticate the packages belong to that specific repository.
Download this key to your Raspberry Pi by using the following command in the terminal.
curl -L https://archive.raspbian.org/raspbian.public.key | gpg --dearmor | sudo tee /usr/share/keyrings/raspbian-archive-keyring.gpg >/dev/null
5. With the GPG we can finally add the older Raspbian repository to our sources list.
To add this repository we will be creating a new file called “
stretch_mongodb.list” in the “
Using this simple one liner, we can echo the repository string and add it straight into this new file without having to use a text editor like nano.
echo "deb [signed-by=/usr/share/keyrings/raspbian-archive-keyring.gpg] http://archive.raspbian.org/raspbian stretch main" | sudo tee /etc/apt/sources.list.d/stretch_mongodb.list
6. As we have made changes to the package sources, we need to update the package list.
You can update the package list by using the following command on your Raspberry Pi.
sudo apt update
Installing the UniFi Controller to the Raspberry Pi
1. Our first task is to add the UniFi repository to our sources list.
We can achieve this by running the command below.
echo 'deb [signed-by=/usr/share/keyrings/ubiquiti-archive-keyring.gpg] https://www.ui.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list
2. We now need to add the repositories GPG key by using the following command.
curl https://dl.ui.com/unifi/unifi-repo.gpg | sudo tee /usr/share/keyrings/ubiquiti-archive-keyring.gpg >/dev/null
The GPG key is what helps tell the package manager it is downloading the correct package.
3. As we made changes to the repositories, we need to now update the package list by running the command below.
sudo apt update
4. Now finally, we can install version 8 of the OpenJDK runtime as well as the Unifi Controller software itself to our Raspberry Pi by running the following command.
sudo apt install openjdk-8-jre-headless unifi
Installing UniFi through this method will automatically set up a service. This service will automatically start the UniFi software at boot.
Additionally, we are installing version 8 of the Java runtime environment as it is currently the only version supported by the UniFi controller.
First Boot of the UniFi Controller on your Raspberry Pi
In this section, we are going to walk you through the initial configuration steps of the UniFi software.
1. First, retrieve the local IP address for your Raspberry Pi.
If you have terminal access to your Pi, you can use the following command.
2. With your Raspberry Pi’s IP address handy, go to the following web address in your favorite web browser.
If you run into a certificate error, it is safe to ignore it as we know what device we are connecting to.
3. The first step requires you to give a name for your Raspberry Pi powered UniFi controller (1.).
You are also required to agree to the end-user license agreement and terms of service from UniFi, once you have read through them, click the checkbox (2.).
Once all done, click the “Next” button (3.) to proceed.
4. Next, you will need to sign in to your Ubiquiti account (1.).
If you don’t already have an account, you can register at the Ubiquiti website.
Once you have entered your login details, proceed by clicking the “Next” button.
5. Tweak the settings on this page that best suits your needs.
Once configured, click the “Next” button.
6. Use this screen to connect your Pi UniFi Network controller to the devices on your network.
To proceed, click the “Next” button.
7. Now give your new Wi-Fi network a name and a password.
Once you have configured your WiFi details (1.), click the “Next” button to proceed (2.).
8. This final screen will get you to review all your settings.
You will also be able to use this screen to set both the country and timezone (1.). Make sure you set these before continuing.
Once you have verified everything is correct, you can now click the “Finish” button (2.) to finish the setup process.
7. At this point, you should now have successfully set up the UniFi network controller on your Raspberry Pi.
