Install NetData on Ubuntu 20.04/18.04 using NetData Automated Installer Script

In this tutorial, we will install NetData on Ubuntu 20.04/Ubuntu 18.04 using the most recommended method as per the NetData installation guide. This involves the use of the automatic one-line installation script which usually works out of the box on all Linux distributions.

To use the NetData automated installation script, simply execute the command below;

Be sure to run the script as an administrative user using a BASH shell.

bash <(curl -Ss https://my-netdata.io/kickstart.sh)

Basically, the script installs NetData from the source code. It therefore downloads and installs all the package dependencies and build tools required to install and run NetData.

The script runs interactively. Follow the prompts to install NetData on Ubuntu 20.04/18.04;

...
[/tmp/netdata-kickstart-2PuU0j/netdata-v1.24.0-49-gc6ba56af]$ sudo ./netdata-installer.sh --auto-update

  You are about to build and install netdata to your system.

  It will be installed at these locations:

   - the daemon     at /usr/sbin/netdata
   - config files   in /etc/netdata
   - web files      in /usr/share/netdata
   - plugins        in /usr/libexec/netdata
   - cache files    in /var/cache/netdata
   - db files       in /var/lib/netdata
   - log files      in /var/log/netdata
   - pid file       at /var/run/netdata.pid
   - logrotate file at /etc/logrotate.d/netdata

  This installer allows you to change the installation path.
  Press Control-C and run the same command with --help for help.


  NOTE:
  Anonymous usage stats will be collected and sent to Google Analytics.
  To opt-out, pass --disable-telemetry option to the installer or export
  the environment variable DO_NOT_TRACK to a non-zero or non-empty value
  (e.g: export DO_NOT_TRACK=1).

Press ENTER to build and install netdata to your system > press ENTER

Once the installation is done, the script will tell you that it is done and NetData is installed and running;

...
netdata by default listens on all IPs on port 19999,
so you can access it with:

  http://this.machine.ip:19999/

To stop netdata run:

  systemctl stop netdata

To start netdata run:

  systemctl start netdata

Uninstall script copied to: /usr/libexec/netdata/netdata-uninstaller.sh

Allow NetData Web Interface External Access

NetData by default listens on all IPs on port 19999.

sudo netstat -altnp | grep :19999
tcp        0      0 0.0.0.0:19999           0.0.0.0:*               LISTEN      2142/netdata        
tcp6       0      0 :::19999                :::*                    LISTEN      2142/netdata

Therefore, to allow external access to NetData web dashboard, you need to open this port on the UFW, if it is running.

sudo ufw allow 19999/tcp

Accessing Netdata Web Interface

You can now access your NetData Web interface via the address http:<hostname-or-IP>:19999. This should land you on the beautiful various system metrics NetData dashboard.
