How to install InfluxDB on Ubuntu 20.04

InfluxDB is an open-source time-series database. It is used for storage and retrieval of time series data in fields such as operation monitoring, operations metrics, internet of things sensor data, and real-time analytics. In this tutorial, we are going to learn how to install InfluxDB on Ubuntu 20.04.

By default, InfluxDB uses the following network ports for communication. If you need to change any port configuration head over to /etc/influxdb/influxdb.conf.

  • TCP port 8086 for client-server communication.
  • TCP port 8088 for RPC service to perform backup and restore operations.

Why InfluxDB?

  • It provides deep insight and analytics
  • InfluxDB is optimized for developer productivity
  • It has best UI which features dashboard, explorer and script editor.
  • It has faster time to market. That is production is faster while usin influxDB.
  • It is easy to build and easy to share templates.


  • You need to be root to perform tasks
  • Have basic knowledge of terminal.
  • Have Ubuntu 20.04 server up and running.

Installing InfluxDB on Ubuntu 20.04

1. Update system repositories

In order to make our system repositories up to date, use the following command in your terminal.

$ sudo apt update && apt upgrade 

2. Add InfluxDB repository to Ubuntu Repository

To install the stable latest version using apt, run the following command using curl.

Add key

$ curl -s | gpg --dearmor > /etc/apt/trusted.gpg.d/influxdb.gpg
$ export DISTRIB_ID=$(lsb_release -si); export DISTRIB_CODENAME=$(lsb_release -sc)

3. Add Repository

$ echo "deb [signed-by=/etc/apt/trusted.gpg.d/influxdb.gpg]${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" > /etc/apt/sources.list.d/influxdb.list

Then update the system repositories again

$ sudo apt update
Get:1 focal InRelease [4736 B]
Hit:2 main InRelease                                                 
Hit:3 focal InRelease                                                                  
Get:4 focal-security InRelease [114 kB]
Hit:5 focal-updates InRelease
Get:6 focal/stable amd64 Packages [1263 B]
Hit:7 focal-backports InRelease   

4. Install influxDB on Ubuntu 20.04

To install the latest stable version of InfluxDB we use the following command:

$ sudo apt install influxdb

The following is the output you will get from the terminal.

The following NEW packages will be installed:
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

After this operation, 153 MB of additional disk space will be used.

5. Configuring InfluxDB

In order to start using InfluxDB, we need to start and enable it.

# start InfluxDB
$ sudo systemctl start influxdb
# enable
$ sudo systemctl enable --now influxdb
# status
$ sudo systemctl status influxdb
● influxdb.service - InfluxDB is an open-source, distributed, time series database
     Loaded: loaded (/lib/systemd/system/influxdb.service; enabled; vendor preset: enabled)

Feb 08 13:04:23 ubuntu[1612]: InfluxDB started
Feb 08 13:04:23 ubuntu systemd[1]: Started InfluxDB is an open-source, distributed, time series database.

Enable –now InfluxDB will ensure that InfluxDB starts every time the server is reloaded. We don’t need to reenable every time.

Whenever you need to enable a certain configuration, head over to /etc/influxdb/influxdb.conf. Lets see an example.

$ sudo vi /etc/influxdb/influxdb.conf

Let’s enabled HTTP on our server, just comment out enabled = true save changes and exit.

To apply the changes stop the server and restart back again.

# stop
$ sudo systemctl stop influxdb
# restart
$ sudo systemctl start influxdb

6. Enable Firewall settings

To ensure that we can access InfluxDB from outside, we need to enable TCP 8086 on the firewall.

To know more about how to enable firewall read this article How to setup Ubuntu 20.04 Server for the first time

$ sudo ufw allow 8086/tcp

To check the status we use ufw enable and status command

$ sudo ufw enable
$ sudo ufw status
Status: active

To                         Action      From
--                         ------      ----
8086/tcp                   ALLOW       Anywhere                  
8086/tcp (v6)              ALLOW       Anywhere (v6)  

7. Launching InfluxDB

To launch InfluxDB we need to point the process to the correct configuration file by using -config flag. Lets see how we can do this.

$ influxd -config /etc/influxdb/influxdb.conf

This is what we get when we invoke the above command.

8888888           .d888 888                   8888888b.  888888b.
