Install InfluxDB

Installation of InfluxDB on Ubuntu22.04|20.04|18.04 is done from Influxdata repository. Once the repo is added, the package can then be installed using an apt package manager. Add the InfluxData repository to the file /etc/apt/sources.list.d/influxdb.list:

# Update packages
sudo apt update && sudo apt upgrade -y

# Install dependencies
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils ncdu git jq chrony liblz4-tool -y

Add repo to Ubuntu

# for Ubuntu 22.04/20.04:
echo "deb https://repos.influxdata.com/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

# for Ubuntu 18.04:
echo "deb https://repos.influxdata.com/ubuntu bionic stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Import GPG key

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

Update apt index and install InfluxDB

sudo apt-get update
sudo apt-get install influxdb

Start and enable the service to start on boot up

sudo systemctl enable --now influxdb

Check service status:

sudo systemctl status influxdb

Configure the InfluxDB Server

Configure a new admin user with root privileges for InfluxDB server.

# start the influx shell and connect to the local InfluxDB instance automatically
influx

# create an admin account
CREATE USER <your_name> WITH PASSWORD '<your_password>' WITH ALL PRIVILEGES

# exit from the InfluxDB shell
quit

Enabling authentication by modifying the main InfluxDB configuration file

sudo nano /etc/influxdb/influxdb.conf

Locate the line # auth-enabled = false under the [http] section. Change the value of auth-enabled from false to true and remove the leading # symbol from the line to uncomment the setting. Restart the influxdb service.

sudo systemctl restart influxdb

Creating an InfluxDB Database

Log in to the InfluxDB server with the admin username and password

influx -username '<your_name>' -password '<your_password>'

Create the database

CREATE DATABASE <database_name>

Check our database

SHOW DATABASES

By default, influxdb service is listening on all interfaces on port 8086.

sudo mv /etc/telegraf/telegraf.conf.sample /etc/telegraf/telegraf.conf.sample.bak
wget -O telegraf.conf https://raw.githubusercontent.com/glukosseth/testnet_guide/main/cosmos/usefull_for_cosmos/monitoring/telegraf.conf
chmod +x telegraf.conf && sudo mv $HOME/telegraf.conf /etc/telegraf/telegraf.conf

Open telegraf.conf

sudo nano /etc/telegraf/telegraf.conf

and replace

<node_name> - server-hostname with your valid hostname
<database_name> - database-name with InfluxDB database nae for this host
<grafana_ip> - ip address with Grafana installed
<database_login> - auth-username with InfluxDB http authentication username
