Database - InfluxDB

Originally written by Grant Reed

(you will need curl & gnupg)

Installing InfluxDB on Mint 19.3 and 20

Start by adding it to the repository

• echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Install GPG Key

• sudo curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -

Update the index and INSTALL

• sudo apt-get update
• sudo apt-get install -y influxdb

Start, Enable and Verify it is running

• sudo systemctl start influxdb
• sudo systemctl enable influxdb
• systemctl status influxdb

Installing InfluxDB on Debian

• sudo apt install influxdb
• sudo apt install influxdb-client

Setting up a Database

This will set up an initial database to start with. This gets really deep, really fast if you are not familiar with databases or the coding behind the system. The guide for this can be found at https://docs.influxdata.com/influxdb/v1.8/introduction/get-started/ Good luck with that.

You need to access InfluxDB so open a terminal on the machine it is hosted on (or SSH into it if that is your thing)... type in the terminal

• influx

You should see a message like this:

$ influx -precision rfc3339
Connected to http://localhost:8086 version 1.8.x
InfluxDB shell 1.8.x
>

A fresh install of if InfluxDB has no useable databases outside of the default internal one. So type this at the prompt, replacing <db-name> with the name you want

• CREATE DATABASE <db-name>

If all went properly, you won't see any additional info, just the prompt again. Now let's make sure that the database is good just for giggles

• SHOW DATABASES

You should see your database listed. If not, something borked and I can't help you with that.

Are you planning to use this with Grafana? You will need to set up a datasource in Grafana then.

Using this with Node Red

A minimum example
