Downloading Netdata package

Now you can proceed further to install the Netdata on Debian.

To install Netdata run the following command on the server.

apt install netdata -y

The -y is used for the confirmation which will be prompted by the installer.

Netdata configuration file

We need to make a small change in the configuration file.

Open the configuration file by entering the following command.

vi /etc/netdata/netdata.conf 

The configuration file will look like this,

[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, the bind socket to IP is set to 127.0.0.1. To access the dashboard using the IP address, you need to replace the 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 = <Enter your IP address here>

Now save the file and restart the Netdata Service using the following command.

systemctl restart netdata
