About this Hands-on Lab

In this hands-on lab, we will be using Zypper to manage software and repositories. We will download a package and make a local repository and then install from that repository.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Query for the Package `nginx`, and Then Use Zypper to Download the Package but Do Not Install It
  1. Run the command:

    sudo zypper se nginx
  2. Answer no to the question.

  3. Make note of the package name, and then download the package:

    sudo zypper in -d nginx
  4. Answer y to download the package.

Create a New Zypper Repo at `/home/cloud_user/localrepo`, Name It `localrepo`, Copy the Docker Package to It, Refresh It, Install Nginx from It, and Verify the Package’s Source
  1. Get the name of the nginx package so we can find it in the cache directory:

    zypper info nginx
  2. Create the folder for the localrepo:

    mkdir ~/localrepo
  3. Copy the RPM file to the localrepo directory:

    cp -r /var/cache/zypp/packages/Server_Applications_Module_x86_64:SLE-Module-Server-Applications15-SP1-Updates/x86_64 ./localrepo
  4. Add the repository and refresh it:

    sudo zypper ar /home/cloud_user/localrepo/x86_64/ localrepo
    sudo zypper refresh
  5. Install Nginx from the localrepo:

    sudo zypper in localrepo:nginx
  6. Answer y to the question.

  7. Verify the installed Nginx came from the local repo:

    sudo zypper info nginx
Start Nginx, Verify It Works, Stop It, and Remove It
  1. Start Nginx:

    sudo systemctl start nginx
  2. Verify it works (a page should load, even if it is an error):

    curl 127.0.0.1
  3. Stop Nginx:

    sudo systemctl stop nginx
  4. Remove Nginx:

    sudo zypper rm nginx
  5. Answer y to remove the package.

Additional Resources

Your enterprise would like to begin managing their own packages. They would like you to do a proof of concept in their SUSE Linux Enterprise development server. You will need to search for the package nginx, and then download the package to a local directory that can be made into a repository. Once you have the local repository created, install the package to ensure it is working. Then, uninstall it so that the RPM can be modified as needed.
