How To Install InfluxDB v2 on Ubuntu 24.04

InfluxDB is a widely adopted time series database system used in storage of time-stamped data. Some of these data include system metrics, system events, industrial sensor data, rainfall measurements, stock prices , and many others meant for analysis. InfluxDB v2 is the latest release of InfluxDB with a lot of improvements from v1. In this article we take a closer look at the process of installing InfluxDB v2 on Ubuntu 24.04 (Noble Numbat).

Step 1: System update

Before we can do the installation, let’s ensure our system is up-to-date.

sudo apt update

An upgrade can also be performed depending on the current system uptime needs.

sudo apt upgrade -y

If an upgrade is performed it might make sense to reboot if required.

[ -f /var/run/reboot-required ] && sudo reboot -f

Step 2: Add InfluxDB APT Repository

The InfluxDB team provides an APT repository for Debian based systems. Add the repository to your system using the commands below.

sudo tee /etc/apt/sources.list.d/influxdb.list<<EOF
deb [signed-by=/usr/share/keyrings/influxdb-keyring.gpg] https://repos.influxdata.com/ubuntu jammy stable
EOF

Import the InfluxDB GPG key used in signing of the packages.

curl -fsSL https://repos.influxdata.com/influxdata-archive_compat.key|sudo gpg --dearmor -o /usr/share/keyrings/influxdb-keyring.gpg

With the repository added and GPG key imported, update system package lists.

sudo apt update

Step 3: Install InfluxDB on Ubuntu 24.04

The next step is actual installation of InfluxDB v2 on Ubuntu 24.04 Linux system.

sudo apt install influxdb2

Command execution output:

eading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following additional packages will be installed:
  influxdb2-cli
The following NEW packages will be installed:
  influxdb2 influxdb2-cli
0 upgraded, 2 newly installed, 1 to remove and 9 not upgraded.
Need to get 58.8 MB of archives.
After this operation, 20.9 MB disk space will be freed.
Do you want to continue? [Y/n] y

You can start and enable the service for automatic starting.

sudo systemctl start influxdb && sudo systemctl enable influxdb

Step 4: Using InfluxDB v2

Confirm status of InfluxDB service.

$ systemctl status influxdb

Using InfluxDB UI

You can use InfluxDB UI that provides a web-based visual interface from where you can interact with and administer your InfluxDB server. This UI is packaged as part InfluxDB. To access InfluxDB web UI, visit http://serverip:8086 in your browser.

Click “Get Started” to begin the initial configurations. Create initial admin user, bucket, and organization.

Copy token printed in the next page.

You are ready to go in a few seconds. Explore documentation pages on how to send data to InfluxDB database.

Using CLI

To connect to InfluxDB from CLI you will need:

• InfluxDB Host
• Organization name
• Token

The syntax used is

influx config create --config-name CONFIG_NAME \
  --host-url http://localhost:8086 \
  --org ORG \
  --token API_TOKEN \
  --active

You can use the token generated earlier. If this is lost create a new one under Load Data–>API Tokens

Use “Generate api token” button to create a new token.

Give the token a name.

Copy the contents of the token and use to connect. We can save these two as variables.

API_TOKEN="EFNTYNar0wp3FdzL1wM-HAnKI_2WTogSSosfXTKiVGLLcAiW5QV7-60adV_D2mzSpGrFj5HyHOF9ArKNTl-UIQ=="
ORG="CloudSpinx"

Create influx CLI config and set it as active:

influx config create --config-name influx01 \
  --host-url http://localhost:8086 \
  --org $ORG \
  --token $API_TOKEN \
  --active

Our connection state:

Active	Name		URL			Org
*	influx01	http://localhost:8086	CloudSpinx

You can get more information about influx CLI commands on CLI reference documentation.
