Installing and running the Unifi software on a raspberry Pi is actually straight forward and will not take you long to setup.
By setting uo the Unifi Network controller you can manage all your Unifi devices with a central interface.
You will need to ensire you have a Os on the SD card, Personally I use the Pi OS Lite.
Once you have installed your os and SSH into your Raspberry Pi, follow the below steps to get started.
sudo apt update
sudo apt upgrade
Install Headless Java
sudo apt install openjdk-8-jre-headless
Install rng-tools, This will ensure the Pi has enough entropy for the random number generator that the Unifi Software uses.
sudo apt install rng-tools
Make a small config change in rng-tools
sudo nano /etc/default/rng-tools
Find and uncomment the following line #HRNGDEVICE=/dev/hwrng
HRNGDEVICE=/dev/hwrng
Press CTRL + X, the Y followed by ENTER
This will save the changes, restart rng-tools
sudo systemctl restart rng-tools
Lets get installing, We will need to add the UniFi repository
echo 'deb https://www.ui.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list
sudo wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg https://dl.ui.com/unifi/unifi-repo.gpg
Run a package update
sudo apt update
Finally, Install the Unifi Controller software
sudo apt install unifi
Once installed you can browse to the server on your computer https://[IPADDRESS]:8443 if you cannot find / know the IP address run the following command.
hostname -I
Enjoy
