Installing Unifi Controller in Fedora 33 is easy. Step one: install MongoDB from the official site since it is no longer available in Fedora due to licensing reasons. Use EL8 version which appears to work fine:
# dnf install ./mongodb-org-server-4.4.4-1.el8.x86_64.rpm
If you haven’t enabled RPMFusion repository, do it:
# dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
Install the controller:
# dnf install unifi
For some reason, unifi has hardcoded path to java alternatives symlink which did not work on the initial start (/usr/lib/jvm/jre-1.8.0/bin/java), reinstalling Java did help:
# dnf reinstall java-1.8.0-openjdk-headless
And enable the service:
# systemctl enable --now unifi
Beware, mongo service does not need to be started, unifi service spawns it’s own process:
# systemctl disable --now mongod
