UniFi Controller on ReadyNAS

The guide at the top of this thread is a little bit outdated (Oracle Java is no longer in the repository), so here ist a small update:

I would like to share here the solution that works for me on OS 6.7.4 (x86):

The UniFi Controller needs Java, so we have to install that first.

First we check if Java is already installed (it is not part of the OS, but it may be installed together with some apps):

java --version

If we get back "-bash: java: command not found", Java is not installed on the ReadyNAS, so we have to install it, if we get back a Version String, we can skip the Java installation:

apt-get update
apt-get install install openjdk-7-jdk

Then we have to add the Ubiquiti repository and the key:

echo "deb http://www.ubnt.com/downloads/unifi/debian unifi5 ubiquiti" | tee /etc/apt/sources.list.d/100-ubnt.list
apt-key adv --keyserver keyserver.ubuntu.com --recv C0A52C50

After that, we can install the UniFi controller:

apt-get update
apt-get install unifi

I copied the systemd service file, to /etc/systemd/system in the case that I have to make some tweaks:

cp -p /lib/systemd/system/unifi.service /etc/systemd/system

After the install there is the problem, that the software is installed unter /var/lib on the OS partition and the included MongoDB will need 3GB under /var/lib/unifi/db, which is not available.

So we have to move the UniFi controller to a place with sufficient space, e.g. /apps:

cd /var/lib
mv unifi /apps
ln -s /apps/unifi unifi

As the last step we now can update the logrotate configuration to rotate also the Unifi logs:

bash -c 'cat >> /etc/logrotate.d/unifi << EOF
/var/log/unifi/*.log {
    rotate 5
    daily
    missingok
    notifempty
    compress
    delaycompress
    copytruncate
}
EOF'

And now the Unifi controller should start with:

systemctl start unifi.service

To access the User Interface of the controller navigate to:

https://<IP_of_your_ReadyNAS>:8443

If it is not working, it might be worth to look into the logs in /var/log/unifi.


Possible problems:

• Unifi needs the ports 3478, 8080, 8443, 8843, 8880, 8881, 8882 and 27117. If other Apps use these ports you have to change the settting of UniFi.
