Install NetData On Linux

Netdata can be installed on any Linux distributions that have Bash installed.

The easiest way to install Netdata is to run the following one-liner command from the Terminal:

$ bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)

This will download and install everything needed to up and run Netdata.

Some users may not want to inject something directly into Bash without investigating it. If you don’t like this method, you can follow the steps below to install it on your system.

On Arch Linux:

The latest version is available in the Arch Linux default repositories. So, we can install it with pacman using command:

$ sudo pacman -S netdata

On DEB and RPM-based systems

NetData is not available in the default repositories of DEB based (Ubuntu / Debian) or RPM based (RHEL / CentOS / Fedora) systems. We need to install NetData manually from its Git repository.

First install the required dependencies:

# Debian / Ubuntu
$ sudo apt-get install zlib1g-dev uuid-dev libuv1-dev liblz4-dev libjudy-dev libssl-dev libmnl-dev gcc make git autoconf autoconf-archive autogen automake pkg-config curl
# Fedora
$ sudo dnf install zlib-devel libuuid-devel libuv-devel lz4-devel Judy-devel openssl-devel libmnl-devel gcc make git autoconf autoconf-archive autogen automake pkgconfig curl findutils
# CentOS / Red Hat Enterprise Linux
$ sudo yum install epel-release
$ sudo yum install autoconf automake curl gcc git libmnl-devel libuuid-devel openssl-devel libuv-devel lz4-devel Judy-devel lm_sensors make MySQL-python nc pkgconfig python python-psycopg2 PyYAML zlib-devel
# openSUSE
$ sudo zypper install zlib-devel libuuid-devel libuv-devel liblz4-devel judy-devel openssl-devel libmnl-devel gcc make git autoconf autoconf-archive autogen automake pkgconfig curl findutils

After installing the required dependencies, install NetData on DEB or RPM based systems as shown below.

Git clone the NetData repository:

$ git clone https://github.com/netdata/netdata.git --depth=100

The above command will create a directory called ‘netdata’ in the current working directory.

Change to the ‘netdata’ directory:

$ cd netdata/

Finally, install and start NetData using command:

$ sudo ./netdata-installer.sh
