I made a new clean install of openHAB 2.5.0.M3 Milestone Build. Then I installed InfluxDB+Grafana through the openhabian Configuration Tool. All went fine but when I wanted to create the Database with

> influx  
> CREATE DATABASE openhab\_db

I get this error:

> ERR: unable to parse authentication credentials  
> Warning: It is possible this error is due to not setting a database.  
> Please set a database with the command “use ”.

I don´t know what I have missed.  
User:

> [12:29:05] openhabian@openhab:~$ influx

Grafana website works.  
I also tried the solution from chris669

> OK, Reply to myself… After investigating through the forum, I’ve seen this [post](https://community.openhab.org/t/problems-installing-influxdb/62098/14) and now for those who encountered the same problem, beware, the script installing InfluxDB and Grafana doesn’t do all the job. **DATABASE is not installed!**  
> In my case, after a clean install, I had to proceed this way:  
> sudo chown -hR openhab:openhab /etc/openhab2  
> sudo chown openhab:openhabian /etc/openhab2/services/influxdb.cfg  
> influx -port 8086 -username myusername -password mypassword -host localhost  
> CREATE DATABASE openhab\_db  
> CREATE USER myusername WITH PASSWORD ‘mypassword’ WITH ALL PRIVILEGES  
> CREATE USER openhab WITH PASSWORD ‘myopenhabpassword’  
> CREATE USER grafana WITH PASSWORD ‘mygrafanapassword’  
> GRANT ALL ON openhab\_db TO openhab  
> GRANT READ ON openhab\_db TO grafana

But it doesn´t work.
