Raw newbie question

First and foremost, I know NOTHING about databases, consequently extremely pedantic explanations are absolutely essential.

I’m installing influx and grafana on raspbian buster to record temperature readings. The instructions I’m attempting to follow originate at circuits.dk. As far as I’m aware, I have influx installed .
influxd version returns 'InfluxDB v1.6.4 (git: unknown unknown)
curl -i ‘http://localhost:8086/ping’ returns HTTP/1.1 204 No Content etc etc
influx returns -bash: influx: command not found

I checked the FAQ and found nothing of assistance

My guess is that influx is installed but not running, for reasons way beyond my level of knowledge

Advice please

BTW, ps -A tells me influxd is running, so why isn’t ‘influx’ responding ?

After perusing a number of posts, I stumbled across a post by someone who experienced the same issue and solved it by installing influxdb-client. That ‘appears’ to have helped, at least influx returns ‘Connected to http://localhost:8086 version 1.6.4’ and ‘InfluxDB shell version 1.6.4’. Shame the instructions don’t include ALL the information needed.

@praxidice can you tell me how you installed InfluxDB, please?

Thanks

sudo apt-get install influxdb

The instructions said to follow something different but I couldn’t get to first base that way, even editing to replace the earlier versions with buster

wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/os-release
test $VERSION_ID = “7” && echo “deb InfluxDB - Package Repository buster stable” | sudo tee /etc/apt/sources.list.d/influxdb.list

Can you share the output of dpkg -L influxdb please?
