How to do it...

To install ngxtop, you'll first need to install the Python package manager, pip. On a Debian/Ubuntu-based system, you'll need to run the following:

apt-get install python-pip

For a Red Hat- / CentOS-based system, the EPEL repository is required first. To install, run the following:

yum install epel-release
yum install python-pip

Once you have pip installed, you can now install ngxtop:

pip install ngxtop

This will download the required files and install ngxtop for you. It's now ready to use.
