[vagrant@DevopsRoles ~]$ curl -XPOST "http://localhost:8086/query" --data-urlencode "q=CREATE USER \
username WITH PASSWORD 'password' WITH ALL PRIVILEGES"

You need to run any Influxdb commands on the terminal with a specific username and password.

[vagrant@DevopsRoles ~]$ influx -username 'username' -password 'password'

[vagrant@DevopsRoles ~]$ curl -G http://localhost:8086/query -u username:password --data-urlencode "q=SHOW DATABASES"
