Welcome to our guide on how to install InfluxDB on Ubuntu 22.04|20.04|18.04 Linux system. InfluxDB is an Open Source Time Series Database Platform for storing Time Series Data, these are metrics & Events collected from different devices. It is a product of InfluxData and part of TICK Stack – which comprises:
T – Telegraf; This is an agent written in Go for collecting performance metrics from the system it’s running on and the services running on that system. The collected metrics are output to InfluxDB or other supported data stores.
I – InfluxDB
C – Chronograf; A web application written in Go and React.js that provides the tools to visualize your monitoring data and easily create alerting and automation rules.
K – Kapacitor A data processing engine. It can process both stream and batch data from InfluxDB
In my monitoring series guides, I concentrated on the use of:
- Telegraf for collecting metrics from systems
- InfluxDB as Datastore
- Grafana for metrics visualization
InfluxDB installation for CentOS is available –> Install Grafana and InfluxDB on CentOS 7
Install InfluxDB on Ubuntu 22.04|20.04|18.04
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 :
Before you begin update your system APT repository index.
sudo apt updateImport repository GPG key.
curl -fsSL https://repos.influxdata.com/influxdata-archive_compat.key|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/influxdata.gpgThen add InfluxDB APT repository.
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.listUpdate apt index and install InfluxDB on Ubuntu 22.04|20.04|18.04:
sudo apt update
sudo apt install influxdb2Start and enable the service to start on boot up:
sudo systemctl enable --now influxdbCheck service status:
$ systemctl status influxdb

Open influxdb service ports on the firewall
By default, InfluxDB uses the following network ports:
- TCP port 8086 is used for client-server communication over InfluxDB’s HTTP API
- TCP port 8088 is used for the RPC service for backup and restore
If you have UFW service running you’ll need to open port 8086 since telegraf will push metrics using this port.
sudo ufw allow 8086/tcpInfluxDB default configuration file is located under /etc/influxdb/influxdb.conf. Most sections are commented out, you can modify it to your liking and restart influxdb service after.
Configuring InfluxDB
Run the configuration script.
$ sudo influx setup
