Installing htop on Linux

Savvy Linux users are probably familiar with ‘top’, a simple process monitoring program which runs in command line. If you are one such Linux user, you might be interested in the prospect of using a more colourful and interesting UI, which the ‘htop’ offers.

This screenshot of htop will give you an idea of what it looks like:


Benefits of Using htop:

  • Colour meters – displays CPU load, memory usage, etc., so you can easily see if they are within standard levels
  • User interaction supported – user can utilise both mouse and keyboard
  • Sort process list – by CPU%, MEM%, time running, etc., in either ascending or descending sequence
  • Fully customisable – depending on your requirements
  • Help menu – lists all possible commands which is helpful if you are a beginner

How to Install:

It’s important to install Repoforge (previously known as RPMForge) before installing htop. Repoforge will act as a repository from which the files can be pulled.

RHEL, CentOS & Fedora (32-bit)

  • RHEL 5, CentOS 5 & Fedora

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
rpm -Uhv rpmforge-release*.rf.i386.rpm

  • RHEL 6, CentOS 6

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
rpm -ihv rpmforge-release*.rf.i686.rpm

RHEL, CentOS & Fedora (64-bit)

  • RHEL 5, CentOS 5 & Fedora

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
rpm -Uhv rpmforge-release*.rf.x86_64.rpm

  • RHEL 6 & CentOS 6

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

Installing htop

  1. After installing Repoforge, install htop by executing this command:
yum install htop
  1. Run htop by executing this command:


It is even simpler to install htop on Debian because it is already available in the repositories:

  1. Open an SSH session.
  2. Log in using your root user login credentials.
  3. Type “apt-get install htop”.
  4. Run htop by typing “htop”.
  5. Press F10 if you want to quit htop at any time.

WHM/cPanel Users:

Enabling additional repositories on servers with WHM/cPanel can cause issues so this is not recommended. Alternately, you can use wget to get the RPM from http://pkgs.repoforge.org/htop/. Afterwards, use the rpm i-command.
