 Additionally I suggest you to setup authentication or close the InfluxDB Port with a Packetfileter of your choice, if the Machine you use for Scraping has a Internetfacing Interface.
 
+```
+> CREATE USER tesla WITH PASSWORD '<password>'
+> GRANT ALL ON tesla TO tesla
+```
+
+Enable authentication by setting the auth-enabled option to true in the [http] section of the configuration file:
+
+```
+$ sudo nano /etc/influxdb/influxdb.conf
+    [http]
+        auth-enabled = true
+
+$ sudo service influxdb restart
+
+$ influx -username admin -password <password>

+NOTE:
+Maybe the following commands must be used instead of restart
+$ sudo service influxdb stop
+$ sudo influxd -config /etc/influxdb/influxdb.conf
+Ctrl+C
