unifi db - DbServer stopped - Unifi controller solved

A nice simple fix from SYSADMIN:

sudo rm -f /usr/lib/unifi/bin/mongod

sudo nano /usr/lib/unifi/bin/mongod

Paste the following in the mongod file:

#!/bin/bash
exec /usr/bin/mongod ${*//--nohttpinterface/}

Save the file and add permissions with the following command:

sudo chmod +x /usr/lib/unifi/bin/mongod
