How To Install Netdata on Debian 11

In this tutorial, we will show you how to install Netdata on Debian 11. For those of you who didn’t know, Netdata is an open-source tool designed for the real-time system performance monitoring solution. It monitors processes such as memory, CPU utilization, disk input/output, network bandwidth, system applications, and MySQL database among other system real-time metrics. The metrics are visualized on stunning interactive dashboards in form of graphical charts.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Netdata Monitoring tool on a Debian 11 (Bullseye).

Prerequisites

• A server running one of the following operating systems: Debian 11 (Bullseye).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Netdata on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade

Step 2. Installing Netdata on Debian 11.

By default, Netdata is available on Debian’s base repository. You can install Netdata on the Debian system by running the following commands below:

sudo apt install netdata

After installation to be able to start, stop, and get the status of the Netdata service use the command below:

sudo systemctl start netdata
sudo systemctl stop netdata
sudo systemctl status netdata

Step 3. Configure Netdata.

Next, edit the Netdata configuration file in your favorite text editor:

nano /etc/netdata/netdata.conf

Add the following lines:

[global]
        run as user = netdata
        web files owner = root
        web files group = root
        # Netdata is not designed to be exposed to potentially hostile
        # networks. See https://github.com/netdata/netdata/issues/164
        bind socket to IP = 127.0.0.1

By default,  bind socket to IP it set to 127.0.0.1. To access the dashboard using the IP address, you need to replace them 127.0.0.1 with your server IP address:

[global]
        run as user = netdata
        web files owner = root
        web files group = root
        # Netdata is not designed to be exposed to potentially hostile
        # networks. See https://github.com/netdata/netdata/issues/164
        bind socket to IP = <Your IP address here>

Save your file and restart the Netdata service:

sudo systemctl restart netdata

Step 4. Configure Firewall.

Now we allow port 19999 to use the UFW firewall:

sudo ufw allow 19999
sudo ufw reload

Step 5. Accessing Netdata Web Interface.

Once successfully installed, you need to type the URL http://(your-domain.com or your-server-IP-addresss):19999 in your favorite web browsers to be redirected to the Netdata dashboard:
