how to start influxdb 2.0.2? - influxdb

Question

ok I installed (in ubuntu 20.04) as it said the official page of influxdb https://portal.influxdata.com/downloads/, specifically these commands:
wget https://dl.influxdata.com/influxdb/releases/influxdb_2.0.2_amd64.deb
sudo dpkg -i influxdb_2.0.2_amd64.deb
then add commands to start and create persistence with the daemon.
systemctl enable --now influxdb
systemctl status influxdb
and it comes out as if it was activated and running normally

What should I add to be able to write "influx" and go directly to the DB to make queries? is it something with the ip address?
When I enter influx, I only get help options but it doesn't say anything about connecting or something like that.
by the way here https://docs.influxdata.com/influxdb/v2.0/get-started/ it is installed in a different way but it is supposed that both ways work well.
thanks.

Usually tools like Telegraf are used to collect data and write it to InfluxDB. You can install Telegraf on each server you want to collect data from.
https://docs.influxdata.com/telegraf/v1.17/
You can browse to http://your_server_ip:8086 and login to chronograf (included to InfluxDB 2.0). Here you can create dashboards and query data from InfluxDB.
Its also possible to do manual queries via the InfluxDB CLI. You can simply use it with the influx query command in your terminal.
https://docs.influxdata.com/influxdb/v2.0/query-data/
Note that some commands need authentication before you are allowed to execute them (e.g. the user command). You can authenticate by adding the -t parameter followed by a valid user token (can be found in the web interface).
Example: influx -t token_here user list
Hope this helps you out.
