About this Hands-on Lab

In this hands-on lab, we will install an RPM package on a CentOS7 system. On rpm-based Linux distributions, we can install rpm packages using the `rpm` command.

This gives us the hands on experience of installing and removing rpm packages directly, without the use of a more comprehensive package manager like yum.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install the `htop` RPM Package
  1. The htop RPM package is located in the cloud_user home directory. In order to install the package, we need to elevate our permissions using sudo. If you don’t see the rpm file, wait a minute and re-run the ls command.
  2. Run the following command to elevate permissions and install the RPM package (Disregard the NOKEY warning):

    Use the following command to install the package:

    sudo rpm -i htop-2.2.0-3.el7.x86_64.rpm
Run the `htop` Application
  1. Now that htop is installed, we can run it with the htop command.
    htop

    This utility shows us system load and running processes.

  2. We can exit the application by pressing the Q key.
Remove the `htop` Package
  1. Use RPM to remove the htop package.
    sudo rpm -e htop
  2. Try re-running the htop command to verify it is uninstalled.
    htop

Additional Resources

An RPM file has been placed into the cloud_user home directory at /home/cloud_user.

Follow along with the video as we install the RPM package, run the new utility it provides, and then remove the package.

Note: Please wait about 2 minutes before starting the lab to make sure the lab has fully provisioned and use a standalone SSH Client instead of the Instant Terminal (in order for htop to display).
