If you see an error like “Unable to start Unifi Cannot find JAVA_HOME”. You will need to edit the unifi start up script.

sudo vi /etc/init.d/unifi

Look for the line JAVA_HOME and replace it with your Java version’s directory

JAVA_HOME=/usr/lib/jvm/java-7-oracle

echo "unifi.db.extraargs=--smallfiles" >> /var/lib/unifi/system.properties

rm -rf /var/lib/mongodb/journal
rm -rf /var/lib/unifi/db/journal
du -a / | sort -n -r | head -n 20

sudo service unifi restart

or

sudo /etc/init.d/unifi restart
