To my disappointment Unifi Controller install on Ubuntu 18.04 fails big time. Their packages … Error message is somehow cryptic enough :
[2018-06-22 16:18:14,046] INFO db - waiting for db connection... [2018-06-22 16:18:14,546] INFO db - Connecting to mongodb://127.0.0.1:27117 [2018-06-22 16:18:15,164] ERROR system - [exec] error, rc=2 [2018-06-22 16:18:15,164] INFO db - DbServer stopped [2018-06-22 16:18:19,209] ERROR system - [exec] error, rc=2 [2018-06-22 16:18:19,211] INFO db - DbServer stopped [2018-06-22 16:18:23,247] ERROR system - [exec] error, rc=2
However i needed Unifi controller in order to control / setup an UniFi AP-AC-Pro ( we have one testing for one of our clients ). After some searching and tweaking around here how we fixed it:
cd /usr/bin sudo mv mongod mongod.bin
And replace mongod with:
#!/bin/bash
cleaned_args=$(echo $* | sed -e 's/--nohttpinterface//')
exec /usr/bin/mongod.bin ${cleaned_args}
then
chmod +x mongod
Restart unifi service and point your browser to: http://localhost:8843/ and enjoy.
